Limited Warranty
Arctic Cat Inc. (hereinafter referred to as Arctic Cat) extends a limited warranty as described below on each new Arctic Cat Snowmobile it assembles and on each
genuine Arctic Cat Snowmobile part and accessory assembled and sold by an authorized Arctic Cat Snowmobile dealer. The limited warranty on an Arctic Cat
Snowmobile is extended to the original retail purchaser for the time periods described below; however, the balance of the remaining warranty may be transferred to
another party unless the purchase is for commercial use (see below). Warranty coverage is only available in the country in which the original retail purchase occurs
to the original retail purchaser resident in that country or to a transferee resident in that country of the balance of the remaining warranty.
Arctic Cat warrants only the products it assembles and/or sells and does not warrant that other products will function properly when used with an Arctic Cat
Snowmobile or will not damage the Arctic Cat Snowmobile. Arctic Cat does not assume any liability for incidental or consequential damages.
Arctic Cat will repair or replace, at its option, free of charge (including any related labor charges), any parts that are found to be warrantable in material or workmanship.
This repair work MUST be done by an authorized Arctic Cat Snowmobile dealer. No transportation charges, rental charges, or inconvenience costs will be paid by Arctic
Cat. The warranty is validated upon examination of said parts by Arctic Cat or an authorized Arctic Cat Snowmobile dealer. Arctic Cat reserves the right to inspect such
parts at its factory for final determination if warranty should apply.
The warranty periods are as follows:
1. For snowmobiles used for recreational purposes:
—If purchased between May 1 and November 30, warranty expires ONE (1) YEAR from December 1 of the current year.
—If purchased between December 1 and April 30, ONE (1) YEAR from the date of sale.
2. For snowmobiles used for commercial purposes (including rental operations), ONE (1) YEAR from the date of invoice and/or 5000 MILES whichever comes first
(non-transferable).
3. THIRTY (30) DAYS from date of sale of snowmobile on Arctic Cat supplied batteries.

FOREWORD
Congratulations! You have chosen a quality Arctic Cat Snowmobile designed and manufactured to give dependable service. Be sure, as the owner/operator of an Arctic Cat Snowmobile, to become thoroughly familiar with its
basic operation, maintenance, and off-season storage procedures. Read this manual and the accompanying Snowmobile Safety Handbook before operating the snowmobile to ensure safe and proper use of your new Arctic Cat
Snowmobile. Always operate the snowmobile within your level of skill and current terrain conditions.
The Operator’s Manual, Snowmobile Safety Handbook, and snowmobile decals display the words Warning, Caution, and Note to emphasize important information. The symbol ! WARNING identifies personal safetyrelated information. Be sure to follow the directive because it deals with the possibility of severe personal injury or
even death. A CAUTION identifies unsafe practices which may result in snowmobile-related damage. Follow
the directive because it deals with the possibility of damaging part or parts of the snowmobile. The symbol
NOTE: identifies supplementary information worthy of particular attention.
This manual covers operator-related maintenance, operating instructions, and off-season storage instructions. If
major repair or service is ever required, contact an authorized Arctic Cat Snowmobile dealer for professional service.
At the time of publication, all information and illustrations were technically correct. Some illustrations used in this
manual are used for clarity purposes only and are not designed to depict actual conditions. Because Arctic Cat Inc.
constantly refines and improves its products, no retroactive obligation is incurred.
This Operator’s Manual should be considered a permanent part of the snowmobile and must remain with the snowmobile at the time of resale. If the snowmobile changes ownership more than once, contact Arctic Cat Inc., Service
Department, P.O. Box 810, Thief River Falls, MN 56701, for proper registration information.

! WARNING
This snowmobile is a very high performance snowmobile. Because it does accelerate rapidly and is capable
of very high speeds, it should not be operated by a
novice or an inexperienced operator. Never accelerate
rapidly or drive at high speed beyond the limits of visibility or without being totally familiar with the terrain
and what lies in front of you. Obey speed limits and
never operate at speeds that do not allow adequate
maneuvering and stopping distances. Read and study
the entire Operator’s Manual and Safety Handbook.
Failure to follow this warning could result in personal
injury to yourself or others.
PARTS AND ACCESSORIES
When in need of replacement parts, oil, or accessories for your Arctic Cat Snowmobile, be sure to only
use GENUINE ARCTIC CAT PARTS, OIL, AND
ACCESSORIES. Only genuine Arctic Cat parts, oil,
and accessories are engineered to meet the standards
and requirements of your Arctic Cat Snowmobile.
For a complete list of accessories, refer to the current
Arctic Cat Accessory Catalog.
To aid in service and maintenance procedures on this
snowmobile, an Illustrated Parts Manual is available
through your local Arctic Cat Snowmobile dealer.
If the snowmobile is purchased
through the Team Arctic Race
Department Racing Program, there
is no warranty.
Reference Information
The Arctic Cat Snowmobile has two important identification numbers. The Vehicle Identification Number
(VIN) is stamped on the side of the tunnel. The Engine
Serial Number (ESN) is stamped into the crankcase of
the engine.
These numbers are required by the dealer to complete
warranty claims properly. No warranty will be allowed
by Arctic Cat Inc. if the engine serial number or VIN is
removed or mutilated in any way.
Always provide the snowmobile name, VIN, and ESN
when contacting an authorized Arctic Cat Snowmobile
dealer for parts, service, accessories, or warranty. If
the complete engine must be replaced, ask the dealer to
notify Arctic Cat for correct registration information.
Write the appropriate information for your Arctic Cat
Snowmobile in the spaces below. Always use these
numbers when referring to your snowmobile.

Checking Brake Fluid
1. With the brake fluid reservoir in a level position,
check the fluid level. The brake fluid level must be
just below the high mark.
0747-094
2. Install the spindle axle into the spindle; then position the
ski damper into the bottom of the ski making sure the
damper is properly positioned for the desired ski stance.
NOTE: The ski damper must be positioned in the ski
so it is directly under the spindle.
3. With the cap screw hole of the ski centered with the
spindle axle, slide the cap screw with washer through
the outside of the ski and spindle assemblies.
NOTE: Local laws and/or regulations as to maximum width of the ski stance may be applicable.
Always comply with the maximum width laws and/or
regulations when adjusting ski stance.
NOTE: Install the cap screw so the lock nut will be
located to the inside of the ski and the cotter pin slot
in the cap screw will be horizontal with the ski.
SNO-253
2. If the brake fluid level is below the low mark,
remove the reservoir cover and add Arctic Cat
approved brake fluid until the fluid level is just
below the high mark. Install and secure the reservoir cover. Do not allow moisture to contaminate
the brake system.
4. Install the remaining washer and lock nut; then
tighten the lock nut to 35 ft-lb.
NOTE: Assure that the cotter pin slot in the cap
screw is still horizontal with the ski (see illustration);
then proceed to step 7.
5. Install the cotter pin from the back side of the ski cap
screw and spread the pin.
NOTE: Repeat this sub-section on the opposite side.
CAUTION
Brake fluid is highly corrosive. Do not spill brake fluid
on any surface of the snowmobile.
! WARNING
Do not overfill the brake fluid reservoir. Overfilling the
reservoir may cause the brake system to hydraulically
lock. Use only Arctic Cat approved brake fluid.
Checking Brake Lever Operation
Sway Bar
1. Test the operation of the hydraulic brake system
by compressing the brake lever.
2. The brake lever must feel firm when compressed.
Ski Alignment
Checking
Toe-Out Range
0.0 - 12.7 mm (0 - 1/2 in.)
NOTE: Track tension and alignment must be properly
adjusted prior to checking or adjusting ski alignment.
Ski alignment must be performed on a flat, level surface. Ski toe-out must fall within the specified range.
SNO-2232
1. Place the sway bar into position (mounting location) of the chassis.
2. Secure the bar with the two mounting brackets,
four machine screws.
18
1. Raise the front end of snowmobile just high
enough that the ski shocks are fully extended but
the skis are still resting on the floor.
2. From the riding position on the snowmobile,
check that the handlebar is in a straight-forward
direction for driving.
NOTE: Steering can be centered in the chassis by
taking measurements from each side of the drag
link to a location on the chassis which would be of
equal distance from each side of the drag link.
3. Using a very light hold-down strap (bungee cord)
between the ski handles, apply a very light load
approximately 2-4 lb pulling the skis together just
enough to pull the slack.
NOTE: Track tension and alignment must be
properly adjusted prior to placing the straightedge
against the outside edge of the track.
4. Place a long straightedge against the outside edge
of the track so it lies near the inside edge of the
left-side ski.
7. Measure the distance from the straightedge to the
right-side ski edge in two places: 35.5-38.1 cm
(14-15 in.) in front of the spindle and 35.5-38.1 cm
(14-15 in.) behind the spindle. Record the measurements taken for the right side.
! WARNING
The measurement from the front and rear of ski to the
straightedge can be equal (ski parallel to the track),
but the front measurement must never be less (ski
toed-in) or poor handling will be experienced. The
front measurements to the straightedge must not
exceed the rear measurements to the straightedge (ski
toed-out) by more than 12.7 mm (1/2 in.).
8. If ski alignment is not as specified, adjust the alignment of the ski(s) not parallel to the straightedge.
Adjusting
NOTE: The following procedure can be used to
adjust the alignment of either ski.
1. Unlock the steering tie rod by loosening jam nuts (A).
NOTE: The inside jam nuts are left-hand thread. Care
should be taken to rotate them in the proper direction.
729-887E
NOTE: The straightedge should be long enough to
extend from the back of the track to the front of the ski.
5. Measure the distance from the straightedge to the
left-side ski edge in two places: approximately
35.5-38.1 cm (14-15 in.) in front of the spindle and
35.5-38.1 cm (14-15 in.) behind the spindle.
Record the measurements taken for the left side.
SNO-2233A
2. Adjust ski alignment by rotating the tie rod with a
wrench at hex-point (B).
3. When ski alignment is correct, apply blue Loctite
#243 to the jam nut threaded area and tighten to 20
ft-lb. Tighten both jam nuts against the tie rod.
! WARNING
Neglecting to lock the tie rod by tightening the jam
nuts may cause loss of snowmobile control and possible personal injury.
NOTE: To allow equal rotation of the tie rod end
ball joints, secure the tie rod jam nuts with the tie
rod ends positioned 90° from each other.
729-887D
6. Place the straightedge against the outside edge of the
track so it lies near the inside edge of the right-side ski.
19
Also, if the snowmobile is to remain on a trailer after
filling the gas tank, the bed of the trailer must be maintained level to prevent gasoline from draining out
through the gas tank vent hose.
! WARNING
Always fill the gas tank in a well-ventilated area. Never
add gasoline to the snowmobile gas tank near any
open flames or with the engine running. DO NOT
SMOKE while filling the gas tank. Do not sit on the
snowmobile without first installing the gas tank cap.
0743-088
Recommended Gasoline
CAUTION
Do not use white gas or gasolines containing methanol. Only Arctic Cat approved gasoline additives
should be used.
The recommended gasoline to use in this snowmobile
is minimum 91 octane gasoline with a maximum 10%
ethanol content.
NOTE: For optimum performance, use only 91
octane (minimum) gasoline.
CAUTION
If a situation arises wherein 91 octane non ethanol or
91 octane with maximum 10% ethanol gasoline is not
available, 87 octane gasoline can be substituted in an
emergency; however, the prolonged usage of 87
octane gasoline can cause severe engine damage.
Gasolines containing more than 10% ethanol are not
acceptable gasoline for use in this snowmobile. Do not
use gasolines containing methanol.
Recommended Injection Oil
The recommended oil to use in the oil-injection system
is Arctic Cat C-TEC2 Synthetic 2-Cycle Oil (p/n
6639-520 - 48 oz) This oil is specially formulated to be
used and meets all of the lubrication requirements of
the Arctic Cat C-TEC2 snowmobile engine.
CAUTION
Any oil used in place of the recommended oil could
cause serious engine damage.
Filling Gas Tank
Since gasoline expands as its temperature increases,
the gas tank must be filled to its rated capacity only.
Expansion room must be maintained in the tank particularly if the tank is filled with cold gasoline and then
moved to a warm area.
Engine Break-In
The Arctic Cat engine (when new or rebuilt) requires a
short break-in period before the engine is subjected to
heavy load conditions.
During the break-in period (one tank of fuel), a maximum of 1/2 throttle (with varying throttle positions) is
recommended; however, brief full-throttle accelerations and variations in driving speeds contribute to
good engine break-in.
Premixing fuel and oil during the break in period is not
required. With the oil delivery control strategy of the
electronic oil pump, the pump will automatically compensate and deliver a richer fuel-to-oil ratio during the
engine break-in period.
Some may choose to pre-mix the first tank and if this
is the case, a pre-mix ratio of 100:1 is acceptable. A
pre-mix ratio of 100:1 combined with the richer fuel/
oil delivered from the electronic oil pump during
break-in may cause additional smoke at start up and
idle.
Preoperation Checks
1. Visually check all fluid levels. Add fluids as necessary.
2. Visually check the entire snowmobile for any
loose fasteners. Tighten as required.
3. Start and run the engine to operating temperature.
4. Check all switches (tether, dimmer, brakelight,
emergency stop) to make sure all function properly; then visually check the headlight, taillight,
and brake light for proper illumination.
5. Test the operation of the brakes. The brake lever
must feel firm when the lever is compressed.
Inspect the brake fluid level. The brake fluid level
must be just below the high mark on the brake
fluid reservoir. Add Arctic Cat approved brake
fluid as necessary.
Checking Headlight Aim
1. Position the snowmobile on a level floor so the
headlight is approximately 8 m (25 ft) from an
aiming surface (wall or similar surface).
NOTE: There should be an “average” operating
load on the snowmobile when adjusting headlight
aim.
20
2. Measure the distance from the floor to midpoint of
the headlight.
3. Using the measurement obtained in step 2, make a
horizontal mark on the aiming surface.
4. Make a vertical mark which intersects the horizontal mark on the aiming surface directly in front of
the headlight.
5. Engage the brake lever lock and start the engine.
Move the headlight dimmer switch to the HIGH
beam position. DO NOT USE LOW BEAM.
6. Observe the headlight beam aim. Proper aim is
when the most intense beam is centered on the vertical mark 5 cm (2 in.) below the horizontal mark
on the aiming surface.

0745-813
7. Adjust the headlight adjustment knobs until correct aim is obtained. Shut the engine off; then disengage the brake lever lock.
Track Tension/Track Alignment
CAUTION
Track tension has been initially adjusted at the factory
for “run-up testing”; however, track tension (and track
alignment) must be adjusted at the dealership according to the following recommendations.
To adjust track tension/track alignment, use the following procedure.
1. Elevate the snowmobile on a shielded safety stand
high enough to use a spring scale.
! WARNING
The tips of the skis must be positioned against a wall
or similar object for safety.
2. At mid-point of the track (on the bottom side),
hook a spring scale around a track clip; then pull
down on the scale to 9 kg (20 lb). Measure the
deflection (distance) between the bottom of the
wear strip and the inside surface of the track clip.
Compare the measurement with the chart.
0744-067
NOTE: Always loosen the right-side rear axle nut
when adjusting track tension/alignment. The leftside rear axle nut is secured with green Loctite
#609 and should not be loosened or removed.
4. If the distance between the bottom of the wear
strip and the inside surface of the track clip
exceeds specifications, tighten the adjusting bolts.
If the distance between the bottom of the wear
strip and inside surface of the track clip is less than
specified, loosen the adjusting bolts.
5. When proper track deflection is attained, loosen
the right-side rear axle nut just enough to apply
blue Loctite #243 to the axle threads; then tighten
the nut to 40-45 ft-lb.
CAUTION
Make certain the right-side rear axle nut is tightened
or component damage will occur.
21
6. Start the engine and accelerate slightly. Use only
enough throttle to turn the track several revolutions. Shut engine off.
! WARNING
DO NOT stand behind the snowmobile or near the
rotating track. NEVER run the track at high speed
when the track is suspended.
NOTE: Allow the track to coast to a stop. Do not
apply the brake because it could produce an inaccurate alignment condition.
7. When the track stops rotating, check the relationship
of the rear idler wheels and the inner track drive lugs.
If the rear idler wheels are centered between the inner
track drive lugs, no adjustment is necessary.
9. Loosen the right-side rear axle nut; then on the
side of the track which has the inner track drive
lugs closer to the rear idler wheel, rotate the
adjusting bolt clockwise 1-1 1/2 turns.
10. Check track alignment and make necessary adjustments until proper alignment is obtained.
NOTE: Make sure correct track tension is maintained after adjusting track alignment.
11. Loosen the right-side rear axle nut just enough to
apply blue Loctite #243 to the axle threads; then
tighten the nut to 40-45 ft-lb.
! WARNING
If the axle nut is not tightened, the adjusting bolts could
loosen causing the track to ratchet, derail, or lock.
Test Ride
Test ride the snowmobile 5 to 10 minutes. During and
after the test ride, do the following:
1. Burnish the brake pads by driving the snowmobile
slowly and compressing the brake lever repeatedly
until the pads just start to heat up; then allow them
to cool down. This process stabilizes the pad material and extends the life of the pads.
2. Allow the engine to cool; then visually check coolant level. Add coolant as necessary.
0740-118
8. If the idler wheels are not centered between the
inner track drive lugs, adjust track alignment.
! WARNING
Make sure the ignition switch is in the OFF position
and the track is not rotating before checking or adjusting the track alignment.
22
3. Recheck track alignment and tension.
4. Check the engine compartment and underneath the
snowmobile for any signs of fluid leaks (gas, coolant).
General Information
2. While holding the cable housing, lightly pull on
one cable end to remove slack.
3. Measure the amount of exposed cable from the
cable housing to the end of the cable.
Control Locations
0746-486
Arctic Power Valve (APV) System
This RPM and exhaust pipe temperature controlled
servomotor (servo) actuation system adjusts the size of
the exhaust ports to provide peak performance
throughout the RPM range.
At low RPM, the exhaust valves are held in the
DOWN position by return springs. This gives the
engine a “low port” exhaust design calibrated to provide maximum low RPM power.
0735-516
4. Repeat steps 2 and 3 on the other cable; then compare the measurements.
NOTE: Measurements must be within a range of
36.5 mm ± 1 mm.
NOTE: The measurements must be equal and
within the specifications. If the measurements are
within specifications, no adjustment is necessary.
If they are not within specifications, proceed to
step 5.
5. Loosen the jam nut on the cable adjuster to be
adjusted; then using the adjusting nuts, lengthen or
shorten the housing as needed.
6. While holding the adjusting nut in place, tighten
the jam nut securely.
7. Install the actuating cables to the servo.
739-152A
At high RPM, the exhaust valves are raised. This creates a “high port” exhaust design calibrated to provide
maximum performance at high RPM.
CAUTION
If excessive adjustment is required to attain synchronization, the entire adjustment procedure should be
repeated.
Exhaust Controlled Timing (ECT)
System
This system automatically adjusts the ignition timing
to provide maximum performance through a variety of
operating conditions. The ECM unit receives input on
engine RPM (demand) and exhaust pipe temperature
(engine condition) and adjusts the ignition timing
accordingly. This system is not adjustable and is maintenance free.
739-152B
To adjust the APV system, use the following procedure:
If a system fault is suspected, disconnect the exhaust
pipe temperature sensor; then use an ohmmeter to
check continuity of the exhaust pipe temperature sensor located in the expansion chamber. A reading of
either 0 ohm or infinity indicates a failed sensor.
1. Remove the actuating cables from the servo.
23
NOTE: A disabled ECT system WILL NOT cause
engine damage; however, a failed ECT system will
have slower throttle response and may produce
slightly less top-end performance.
NOTE: Do not adjust the handlebar to a position
that allows the brake fluid to be below the low
mark on either side of the master cylinder.
! WARNING
Testing Exhaust Temperature
Sensor
1. Disconnect the sensor harness; then remove the
sensor from the exhaust pipe.
2. Suspend the sensor (only up to the threads) in a
container filled with automatic transmission oil;
then slowly heat the oil on a hot plate.
3. Using a fluid thermometer, closely monitor the oil
temperature, and using a digital multimeter with
the leads connected to the sensor leads, observe
the resistance reading.
4. The resistance must be within the temperature
range (see chart).

5. If the resistance and temperature are not within
specifications, replace the sensor.
NOTE: Before replacing the sensor, repeat the
test to confirm results.
Handlebar Tilt
The handlebar can be adjusted to the operator’s preference. To adjust the handlebar, use the following procedure:
1. Loosen the eight cap screws securing the handlebar
caps to the riser and the riser to the steering post.
Tighten cap screws according to specifications to prevent unexpected “fold-down” of the handlebar during
operation over rough terrain. DO NOT offset the handlebar so steering capabilities are altered or throttle
and brake controls will be affected.
Rear Bumper
The rear bumper can be removed and replaced. To remove/
install a rear bumper, use the following procedure.
1. On the inside of the tunnel, drill out all rivets and
remove both screws and nuts securing the rear
bumper to both sides of the tunnel.
2. Remove the existing bumper and install the new
one aligning the holes with the holes in the brackets; then rivet the rear bumper to both sides of the
tunnel. Secure the front of the bumper using the
existing machine screws and nuts.
Exhaust System
The exhaust system is designed to reduce noise and to
improve the total performance of the engine. If any
exhaust system component is removed from the engine
and the engine is run, severe engine damage will result.
Liquid Cooling System
The cooling system should be inspected daily for leakage and damage. Also, the coolant level should be
checked daily. If leakage or damage is detected and the
operator does not feel qualified to service the cooling
system, see an authorized Arctic Cat Snowmobile
dealer for this service.
When filling the cooling system, use a coolant/water
mixture which will satisfy the coldest anticipated
weather conditions of your area in accordance with the
coolant manufacturer’s recommendations. While the
cooling system is being filled, air pockets may
develop; therefore, fill the bottle and run the engine for
five to ten minutes after the initial fill (until the thermostat opens); then add more coolant if necessary. Fill
the coolant tank and take the snowmobile for a test
ride. Let the engine cool down; then recheck the coolant level and add if necessary.
NOTE: Use a good quality, glycol-based, automotive-type antifreeze.
CAUTION
SNO-2236
2. Adjust the handlebar up or down to operator’s
desired tilt, tighten the cap screws evenly to 15 ftlb, and check steering for maximum right/left turning capabilities.
24
After operating the snowmobile for the initial 5-10 minutes, stop the engine, allow the engine to cool down,
and check the coolant level. Add coolant as necessary.
Drive Clutch And Driven Clutch
Shock Absorbers
The drive clutch and driven clutch do not require lubrication; therefore, no special maintenance is required
by the snowmobile owner. However, the drive clutch
and driven clutch should be disassembled, cleaned,
and inspected before each race.
Each shock absorber should be visibly checked daily for
excessive fluid leakage, cracks or breaks in the lower
case, a bent plunger, and wear or leakage in the hoses. If
any one of these conditions is detected, replacement is
necessary. If the operator does not feel qualified to service or replace shock absorbers, see an authorized Arctic Cat Snowmobile dealer for this service.
NOTE: A small amount of grease should be
applied to the driven shaft before installing the
driven clutch.
When operating the snowmobile at high altitudes, it
may be necessary to change certain component parts
of the drive clutch. If the operator does not feel qualified to change clutch components, see an authorized
Arctic Cat Snowmobile dealer for this service.
CAUTION
Use Clutch Puller (p/n 0744-062). Never substitute a
different puller or drive clutch damage will occur.
Drive Clutch/Driven Clutch
Alignment
The parallelism and the offset between the drive clutch
and driven clutch are set at the factory. Normally, no
adjustment is necessary as long as neither the drive
clutch nor the driven clutch is removed or disassembled. However, if premature drive belt wear is experienced or if the drive belt turns over, the drive clutch/
driven clutch alignment must be checked. If the operator does not feel qualified to align the clutch/clutch,

Operating Instructions
Starting And Stopping Engine
It is imperative that the hydraulic brake system be
checked for wear and proper operation and that all
safety checks found in the accompanying Snowmobile
Safety Handbook be performed before attempting to
start the engine. After the engine has been started,
check the headlights (high and low beam), taillight,
and brakelight to be sure they are working properly
and adjusted correctly. Make sure all lights are clean to
provide maximum illumination. The headlight and
taillight must be clean and must be illuminated whenever the engine is running.
1. Test the operation of the hydraulic brake system
by compressing the brake lever. The brake lever
must feel firm when compressed; then while holding the brake lever in the compressed position,
measure the distance between the brake lever and
the handlebar. The distance must be greater than
2.54 cm (1 in.).
! WARNING
Do not start the engine if the brake system is not functioning properly (if the lever feels spongy, if the brake
lever can be compressed to within 2.54 cm (1 in.) of
the handlebar, or if the brake fluid level is not correct).
Service the brake system or have it properly repaired
prior to operating the snowmobile. Serious personal
injury or even death may occur if the brake system is
not operating properly.
3. Test the throttle control lever by completely compressing and releasing it several times. The lever
MUST return to the idle position quickly and completely.
CAUTION
Always check the coolant level before starting the
engine.
4. Move the emergency stop switch to the RUN position.
5. Assure that the tether switch cap is secured to the
tether switch.
7. Pull the recoil handle slowly until resistance is
felt; then give a short quick pull. Repeat until the
engine starts.
CAUTION
To avoid damaging the recoil starter, DO NOT pull the
recoil rope to its limit or release the recoil handle from
an extended position. Allow the rope to rewind slowly.
CAUTION
0745-816
2. Check the brake fluid level in the master cylinder
reservoir. The brake fluid level must be just below
the high mark on the master cylinder reservoir.
Add Arctic Cat approved brake fluid as necessary.
It is extremely important that the engine is properly
warmed up before subjecting the engine to high speed
operation or heavy loads. Do not idle the engine for
excessively long periods of time. The engine should
be allowed to idle at least 1-2 minutes before it is operated at more than 1/2 throttle. In extremely cold conditions, the warm-up time will be longer. Cold seizure
and piston scuffing caused by insufficient warm-up
will not be covered by warranty. Also, do not idle the
engine for excessively long periods of time.
8. To shut off the engine, either depress the emergency stop switch to the OFF position or pull the
tether switch cap off the tether switch.
Braking
Operating a snowmobile with hydraulic brakes is different from operating a snowmobile with mechanical
brakes. The following items are items that the operator
must be familiar with when operating this snowmobile
and its hydraulic brake system.
SNO-253
26
NOTE: Important additional information on the
proper maintenance of the brake system is found
in the maintenance section of this manual.
1. Use the brakes wisely. Each time the brakes are
applied in all hydraulic brake systems (including
automotive applications), heat is transferred to the
brake fluid. The amount of heat transferred during
high speed stops and/or repetitive use may be high
enough to boil the brake fluid and cause the brakes
to either fade or may cause an unexpected loss of
brakes. If this occurs, the brake fluid requires a cool
down period before the brakes will again function
properly. This cool down period will vary depending
upon the ambient air temperature and the temperature of the brake fluid. If loss of brakes has occurred
because of high fluid temperatures, do not operate
the snowmobile until the cool down period has
expired and brake lever firmness has returned.
! WARNING
Excessive repetitive use of the hydraulic brake for
high speed stops will cause overheating of the brake
fluid and premature brake pad wear which will result
in an unexpected loss of brakes.
2. Be sure to maintain the brake fluid at the proper
level and take care not to get any moisture in the system as moisture in the brake fluid lowers the boiling
point. If the brake fluid is ever boiled (by high speed
stops or repetitive use) or if moisture is allowed to
enter the system, it must be changed. Never substitute or mix different types or grades of brake fluid.
! WARNING
Use only Arctic Cat approved brake fluid. Never substitute or mix different types or grades of brake fluid.
Brake loss can result. Check brake fluid level and pad
wear before each use. Brake loss can result in severe
injury or even death.
3. Never ride the brake. Even maintaining minimal
pressure on the brake lever will cause the brake
pads to drag on the disc and may overheat the
brake fluid.
4. The brake lever lock is not a parking brake and
should not be applied for periods exceeding 5 minutes. NEVER OPERATE THE SNOWMOBILE
WITH THE BRAKE LEVER LOCK ENGAGED.
! WARNING
The brake lever lock is not a parking brake and should
not be applied for periods exceeding 5 minutes. The
brake lever lock maintains the brake lever in the compressed position and maintains pressure against the
brake disc; however, after a period of time, the pressure applied to the brake disc may relax below the
amount required to hold the snowmobile stationary.
5. Pumping the brake lever is permissible but not acceptable on a snowmobile designed for racing; therefore,
if pumping the brake lever more than twice is necessary to obtain the necessary stopping power, the system must be serviced. If the operator does not feel
qualified to service the brake system, see an authorized Arctic Cat Snowmobile dealer for this service.
6. When new brake pads are installed, a “burnishing”
process is required. Drive the snowmobile slowly
and compress the brake lever several times until
the pads just start to heat up; then allow them to
thoroughly cool down. This process stabilizes the
pad material and extends the life of the pads.
Emergency Stopping
There are several methods of stopping or slowing the
snowmobile under a variety of situations. Identified in
the following chart are the ways a snowmobile may be
brought to a stop and the effectiveness under normal
conditions.

! WARNING
If any malfunction of the throttle system occurs (such
as freezing in fluffy snow) and the engine does not idle
down, use the emergency stop switch or disconnect
the tether switch IMMEDIATELY to stop the engine. DO
NOT start the engine until the malfunction in the throttle system has been located and corrected.
! WARNING
If the throttle control lever does not work properly, DO
NOT ATTEMPT TO START THE ENGINE.
27
NOTE: If excessive oil deposits are observed, the
chain case must be serviced. Also, when the oil level
is at the add mark, approximately 2 fl oz of transmission lube must be added to the chain case.
Lubrication
Chain Case
The recommended amount of synthetic chain lube in
the chain case is 15 fl oz. Adding more transmission
lube to the chain case (above the recommended
amount) may result in leakage. To check the transmission lube level, use the following procedure:
NOTE: The snowmobile must be on a level surface
for this procedure.
Check chain case lube level using the chain case sight
glass at the right-side footrest. If the lube is at least
halfway up the sight glass, the level is correct.
CAUTION
The correct lubricant to use in the chain case is Arctic
Cat Synthetic Chain Lube (p/n 5639-038). Any substitute may cause premature chain failure or serious
damage to the chain drive system.
Rear Suspension
1. With the gas tank nearly empty (less than 1/4 full),
lay the snowmobile on its side. A piece of cardboard should be used to protect the finish on the
hood and belly pan.
NOTE: Prior to tipping the snowmobile on its
side, apply the brake and set the brake lever lock.
2. Lubricate the grease fittings with an all-temperature grease.
0746-115
3. If the lubricant level is above the add mark, the
lubricant level is satisfactory. If the lubricant level
is below the add mark, proceed to step 4.
4. If oil is low, add transmission lube by removing the
oil fill plug.

approved brake fluid until the fluid level is just
below the high mark. Install and secure the reservoir cover. Do not allow moisture to contaminate
the brake system.
5. If the distance is less than specified, check the brake
fluid level (see Checking Brake Fluid in this sub-section), inspect for leakage, and check the brake pads.
CAUTION
Brake fluid is highly corrosive. Do not spill brake fluid
on any surface of the snowmobile.
! WARNING
Do not overfill the reservoir. Overfilling the reservoir may
cause the brake system to hydraulically lock. Use only
Arctic Cat approved brake fluid. Never substitute or mix
different types or grades of brake fluid. Brake loss can
result. Brake loss can result in severe injury or even death.
Changing
The brake fluid must be changed on a regular basis and
whenever the brake fluid has been overheated or contaminated. The brake fluid should be changed every
1000 miles or at the end of the snowmobiling season,
whichever occurs first.
Checking Brake Lever Travel
1. Test the operation of the hydraulic brake system by
compressing the brake lever.
! WARNING
Do not operate the snowmobile if the distance between
the compressed brake lever and handlebar is less than
2.54 cm (1 in.). Brake loss may occur. Brake loss can
result in severe personal injury.
Bleeding Brake System
If the brake lever feels spongy when applied, the brake
system may need to be bled. To bleed the brake, use
the following procedure:
1. Remove the reservoir cover and fill the reservoir to
the high mark with Arctic Cat approved brake fluid.
CAUTION
Brake fluid is highly corrosive. Do not spill brake fluid
on any surface of the snowmobile.
! WARNING
Use only Arctic Cat approved brake fluid. Any substitute may result in a loss of brakes.
2. Slide a piece of flexible tubing over the ball of the
bleeder valve and direct the other end into a container.
2. The brake lever must feel firm when compressed.
3. To verify lever travel, compress and hold the brake
lever to its maximum resistance.
NOTE: Do not pump the brake lever as it will produce an inaccurate reading.
4. Measure the distance between the brake lever and the
handlebar. The distance must be greater than 1 in.

during the bleeding process.
NOTE: Changing one pad at a time will prevent
one piston from pushing out the other piston from
the caliper.
5. When the brake fluid is free of all air and the brake
lever feels firm when compressed, fill the reservoir to a level just below the high mark; then
install and secure the cover. Remove the tube from
the bleeder valve.
Checking/Changing Brake Pads
The condition of the brake pads must be checked daily
and changed if worn or damaged. To check and change
the brake pads, use the following procedure.
1. Measure the width of both brake pads. The brake
pad width must be greater than 3.2 mm (0.125 in.).
If the brake pad width is less than specified,
replacement of both pads is necessary. Follow
steps 2-6 to replace brake pads.
2. Remove the pin securing the brake pads to the caliper assembly.
3. Remove the brake fluid reservoir cover; then
remove most of the brake fluid from the reservoir.
Replace the cover.
NOTE: The above procedure will allow room for the
fluid from the caliper when the pistons are pushed
into the caliper for installing new brake pads.
Replacing the cover will prevent fluid spillage.
5. Using a flat-blade tool, slowly and carefully push
the piston into the caliper.
NOTE: The brake pads are labeled (Inner and
Outer) for installation purposes.
6. Position the new brake pad into the caliper.
7. Repeat steps 4-6 for the other pad; then secure the
pads with the pin.
8. Remove the reservoir cover and remove the
remaining fluid; then fill the reservoir with fresh
fluid.
9. Pump the brake lever to ensure correct positioning
of the brake pads; then release.
10. Fill the reservoir to the proper level with fresh
brake fluid.
NOTE: When new brake pads are installed, a
“burnishing” process is required. Drive the snowmobile slowly and compress the brake lever several times until the pads just start to warm up; then
allow them to cool down. This procedure stabilizes
the pad material and extends the life of the pads.

Drive Train/Track/Brake
Systems
This section has been organized into sub-sections for servicing drive train, track, and brake systems; however,
some components may vary from model to model. The
technician should use discretion and sound judgment
when removing and installing components.
NOTE: Whenever a part is worn excessively, cracked,
or damaged in any way, replacement is necessary.
SPECIAL TOOLS
A number of special tools must be available to the technician
when servicing the drive train, track, and brake systems.

NOTE: Special tools are available from the Arctic
Cat Service Parts Department.
CAUTION
Never attempt to substitute any other drive clutch puller for
the recommended puller or severe clutch damage will occur.
Drive Belt
The drive belt transfers power from the drive clutch to
the driven clutch. If the belt is worn, cracked, or
stretched, maximum power will not be transmitted and
the belt could also fail and therefore must be replaced.
Periodic checks (at least once a week under normal
usage) of two drive belt specifications are essential.
1. Measure the outside circumference of the drive
belt. The belt should be within specifications in
circumference.
NOTE: Drive belts should be purchased from an.
authorized Arctic Cat Snowmobile dealer, as Arctic
Cat drive belts are made to exact specifications
and of quality material. Belts made by other manufacturers may not be of the same specifications or
quality and, therefore, usage could result in poor
performance and premature belt failure.
CAUTION
Never run the engine with the drive belt removed.
Excessive revving of the engine could result in serious engine damage and drive clutch failure.
Before starting the snowmobile in extremely cold temperatures, the drive belt should be removed and
warmed up to room temperature. Once the drive belt is
at room temperature, install the drive belt.
Also, drive belts have a break-in period of approximately 10 minutes. After installing a new drive belt,
drive the snowmobile for 10 minutes at 1/2 throttle or
less. This will allow the drive belt to gain its optimum
flexibility and will extend drive belt life.
Breaking-In
Drive belts require a break-in period of approximately
25 miles. Drive the snowmobile for 25 miles at 3/4
throttle or less. By revving the engine up and down
(but not exceeding 60 mph), the exposed cord on the
side of a new belt will be worn down. This will allow
the drive belt to gain its optimum flexibility and will
extend drive belt life.
Removing
1. Remove the tether switch cap and wait for all
moving parts to stop.
2. Set the brake lever lock.
3. Remove the left-side access panel.
4. Using Drive Belt Deflection Tool (p/n 0644-424),
thread the tool clockwise into the driven clutch
until the movable sheave opens far enough to
remove the drive belt.
2. Measure the outside width of the drive belt. The
belt should be within specifications in width.
3. Check the belt for cracking, fraying, etc.
If any of the specifications or conditions are unsatisfactory, replace the drive belt.
743-067B
5. When the sheaves are fully apart, pull up on drive
belt and roll belt over stationary sheave until it is
free of the driven clutch.

push the shaft down into the oil while rotating and
“wiggling” the shaft until there are no bubbles rising in the oil.
11. Gently lower the negative spring and spacer into the oil
taking care not to let the oil overflow into the air sleeve.
CAUTION
Make sure the piston assembly and the rebound hole
in the shaft DO NOT come out of the oil bath. If the
rebound adjust hole in the shaft comes out of the oil
bath, air can transfer to the underside of the piston
aerating the shock. Add oil to the shock as required to
keep the hole covered. Pull the shaft assembly out of
the oil until the top of the negative spring is even with
the end of the body.
12. Carefully lower the bearing assembly into the
damping body and thread into the shock; then
using an appropriate bearing head tool, tighten the
bearing assembly to 50 ft-lb.

Rear Suspension
The Sno Pro 600 is equipped with a compression adjustable remote reservoir shock in the rear suspension system. This system utilizes front arm limiter straps.
The suspension should be adjusted for the operational
needs and riding preference of the operator.
The rear springs influence the load carrying capability
of the snowmobile and should be adjusted for the
weight and riding preference of the operator.
Rear Arm Shock Rebound
The rear arm shock can be adjusted for rebound qualities. To adjust, use the following procedure.
1. Turn the adjuster clockwise until it stops (hard
position).
2. Turn the adjuster counterclockwise to the initial
setting (see appropriate Valve Stacks/Specifications page in this manual) or turn the adjuster
counterclockwise the desired number of “clicks.”
NOTE: On the rear arm shock, the rebound
adjuster has a total range of 18 “clicks” or 4 1/2 full
turns (4 “clicks”= 1 turn).
LLLL
20. Using a high-pressure hand air pump, pressurize
the shocks to 200 psi EVOL and 80 psi Main.

Front/Rear Arm Shock Compression
1. Turn the adjuster clockwise until it stops (hard
position).
2. Turn the adjuster counterclockwise to the initial setting
(see page 9 in this manual) or turn the adjuster counterclockwise the desired number of “clicks.”
NOTE: On the rear arm shock, the compression
adjuster has a total range of 18 “clicks” or 3 full
turns (6 “clicks” = 1 turn).
Front Arm Shock Spring
The skid frame front arm shock spring is adjustable.
However, Arctic Cat recommends that the shock
spring be adjusted to a maximum of 6.4 mm (1/4 in.)
up or down from the standard pre-load setting.
NOTE: The standard pre-load spring length (installed)
is 7.64 in.
CAUTION
Do not exceed the maximum 6.4 mm (1/4 in.) up or
down from the standard pre-load setting.
When customizing the amount of ski pressure, be sure to
not over-adjust the front arm shock spring to adversely
affect steering and operator control of the snowmobile.
Some experimentation may be required until the proper
adjustment for the operator’s individual style is obtained.
! WARNING
Do not adjust the front arm shock to a point at which
steering and operator control of the snowmobile are
adversely affected.
NOTE: Each driver’s style is different and some
experimentation will be required to become familiar with the above adjustment procedure.
! WARNING
DO NOT make adjustments while operating the snowmobile. Keep both hands on the handlebar while the
snowmobile is moving.
Adjusting Rear Spring Tension
Rear spring tension adjustment is accomplished by rotating the adjusting cams. Position 3 provides the stiffest ride,
and position 1 provides the softest ride. Always rotate the
cam from the lighter position to the heavier position.
Servicing Zero-X Shock Absorbers
This procedure shows the proper method for servicing
the front arm shock absorber w/“piggy-back” reservoir.
! WARNING
Before starting, read through all of these instructions
first to become familiar with the procedure. Make sure
the work area is clean and all of the necessary tools
are available. These shocks contain high pressure
nitrogen gas. Always use proper safety equipment
such as latex gloves and safety glasses when working
on shock absorbers.
NOTE: Some illustrations and photographs used
in the following sub-sections are used for clarity
purposes and are not designed to depict actual
conditions.
Disassembling
1. Remove the bearings and retaining rings from the
eyelets.
2. Clean the entire shock assembly with soapy water.
Dry the shock assembly with compressed air.
CAUTION
Use a soft-bristle brush to remove as much dirt and
debris as possible. Do not pressure wash the shock
as this can force water and debris inside causing damage to the seals.
! WARNING
When using compressed air to dry components,
always wear safety glasses.
NOTE: If compressed air is not available, use
clean towel to dry the shock assembly.
3. Clamp the shock body eyelet securely in a softjawed vise and remove the ball from the end cap;
then using a 3/16-in. hex key, slowly loosen the set
screw (FAV3 valve) on the shock reservoir.
! WARNING
Always place a rag or towel over the valve and hex key
for protection when releasing the nitrogen from the
reservoir.
CAUTION
Never force the adjustment cams from the low position to the high position. Cam damage may occur.
To rotate an adjusting cam, use a six-point box-end
wrench. Rotate the wrench until the cam is in the
desired position. To stiffen the ride, rotate the cam so
as to raise the spring end. Make the adjustment on the
other cam and be sure both cams are adjusted equally.

bulb. If the glass is touched, it must be cleaned with a
dry cloth before installing.
1. Disconnect the headlight harness connector from the
bulb; then remove the rubber grommet from the
headlight housing.
Ski Wear Bar
The ski wear bar is a replaceable bar attached to the
underside of the ski. The purpose of the wear bar is to
assist in turning the snowmobile, to minimize ski wear,
and to maintain good steering control. If the snowmobile is operated primarily in deep snow, ski wear bar
wear will be minimal; however, if the snowmobile is
operated on terrain where the snow cover is minimal,
the ski wear bar will wear faster. To maintain positive
steering characteristics, Arctic Cat recommends that
the ski wear bars be checked before each use and
replaced if worn beyond 1/2 of the original diameter.
Ski wear bars are available from an authorized Arctic
Cat Snowmobile dealer.
2. Rotate the bulb retainer counterclockwise until it
unlocks from the housing; then remove the bulb.
! WARNING
Operating the snowmobile with excessively worn or
missing wear bars may result in a loss of steering control.
NOTE: Always check the official rules for the
appropriate wear bars for the event being participated in.
Removing
1. Raise the front of the snowmobile and place it on a
support stand.
0746-096
86
2. Remove the lock nuts (and washers on the Sno
Cross model) securing the wear bar to the ski.
Rail Wear Strip
Arctic Cat recommends that the wear strips be checked
weekly and replaced as necessary. Measure the wear
strips at 25.4 cm (10 in.) intervals. Wear strips must be
10.7 mm (0.42 in.) thick or thicker. If wear strip measurements are less than specified, replacement of both
wear strips is necessary to prevent premature track clip
wear and possible track damage.
NOTE: The rail wear strips will wear rapidly if the
snowmobile is operated on terrain on which the
snow cover is minimal. Loose snow is required to
cool and lubricate the wear strips and prevent
accelerated wear.

Performance Tips
Operating a high performance snowmobile requires a
special attention. Often, a minor adjustment will result in
a large increase in performance. This section is intended
to highlight minor conditions that adversely affect performance and the adjustments needed to correct them. Be
sure, however, to thoroughly read and understand this
entire manual especially the section on spark plugs, track
tension and alignment, and suspension.
DRIVE BELT — This link between the engine and
drive train is often the most neglected component. The
drive belt must have the proper fit in the drive clutch
and driven clutch. Proper fit is when the top surface of
the drive belt is flush with the top or up to 1/16 in.
higher than the driven clutch sheaves (with the sheaves
fully closed). If the belt sits below this level, the snowmobile will bog at slow speeds and will have a slower
maximum speed. To correct this condition, first determine if the drive belt is within specifications (see
Drive Belt section) and replace if worn or too long.
Secondly, always run the drive belt in the same direction. Installing the drive belt so the part number can be
read will ensure that the drive belt is always run the
same direction.
88
DRIVE CLUTCH AND DRIVEN CLUTCH —
Keeping the drive clutch and driven clutch clean
should be the primary consideration of the operator.
The clutch sheaves can be cleaned of any drive belt
accumulation using a clean cloth and parts-cleaning
solvent. All pivot points can be maintained clean using
compressed air.
CAUTION
Use Clutch Puller (p/n 0744-062). Never substitute a
different puller or drive clutch damage will occur.
CARBURETOR MAIN JETS — Proper carburetion,
specifically proper main jets, is absolutely necessary to
obtain peak performance. Since ambient temperature
and operating altitude both affect the main jet size
needed for optimum engine performance, the main jets
will often need to be changed whenever the temperature changes 20° F (11° C) or whenever operating altitude varies by more than 1000 feet.
Preparation For Storage
Prior to storing the snowmobile, it must be properly
serviced to prevent corrosion and component deterioration. To prepare the snowmobile for storage, Arctic
Cat recommends the following procedure.
1. Clean the seat cushion with a damp cloth and Arctic Cat Vinyl Protectant.
2. Clean the snowmobile thoroughly by hosing dirt,
oil, grass, and other foreign matter from the skid
frame, tunnel, hood, and belly pan. Allow the
snowmobile to dry thoroughly. DO NOT get water
into any part of the engine.
8. Drain the chain-case lubricant. Remove the chaincase cover and inspect chain, sprockets, and chain
tensioner for wear and the chain for proper tension. Install the chain-case cover and seal; then
pour Arctic Cat Synthetic Chain Lube (p/n 5639038) into the oil level stick filler hole according to
specifications.
9. Remove the drive belt from the drive clutch/driven
clutch. Lay the belt on a flat surface or slide it into
a cardboard sleeve to prevent warping or distortion
during storage.
10. Clean and inspect the drive clutch and driven
clutch.
11. Apply light oil to the upper steering post bushing
and shafts of the shock absorbers.
3. Place the rear of the snowmobile up on a shielded
safety stand. Remove the air-intake silencer boots
from the carburetors.
12. Lubricate the rear suspension and bellcranks with
a all-temperature grease.
4. Start the engine and allow to idle. With the engine
idling, spray an Engine Storage Preserver into the
carburetors until the engine exhaust starts to
smoke heavily or until the engine starts to drop in
RPM. Turn engine off.
13. Tighten all nuts, bolts, and cap screws making sure
all calibrated nuts, bolts, and cap screws are tightened to specifications. Make sure all rivets holding
the components together are tight. Replace all
loose rivets.
5. Plug the exhaust system outlet with a clean cloth.
14. Clean and polish the hood, console, and chassis
with Cat Cleaner (p/n 4639-371). DO NOT USE
SOLVENTS. THE PROPELLANT WILL DAMAGE THE FINISH.
6. With the tether switch cap removed:
A. Disconnect the high tension leads from the
spark plugs; then remove the plugs, connect
them to the leads, and ground them on the cylinder heads.
CAUTION
Never crank the engine over without grounding the
spark plugs. Damage to coils and/or CDI unit may
result.
B. Pour 29.5 ml (1 fl oz) of SAE #30 petroleumbased oil into each spark plug hole and pull the
recoil starter handle slowly about 10 times.
C. Install the spark plugs and connect the high tension leads.
7. Drain the gas from the carburetor float bowls. Fill
the gas tank to its rated capacity; then add Arctic
Cat Fuel Stabilizer (p/n 0436-907) to the gas tank
following directions on the container for the stabilizer/gasoline ratio. Tighten the gas tank cap
securely.
15. If possible, store the snowmobile indoors. Raise
the track off the floor by blocking up the back end
making sure the snowmobile is secure. Loosen the
track adjusting bolts to reduce track tension. Cover
the snowmobile with a machine cover or a heavy
tarpaulin to protect it from dirt and dust.
16. If the snowmobile must be stored outdoors, position the snowmobile out of direct sunlight; then
block the entire snowmobile off the ground making sure the snowmobile is secure. Loosen the
track adjusting bolts to reduce track tension. Cover
with a machine cover or a heavy tarpaulin to protect it from dirt, dust, and rain.
CAUTION
Avoid storing in direct sunlight and using a plastic
cover as moisture may collect on the snowmobile
causing corrosion.
89
Preparation After
Storage
Taking the snowmobile out of storage and correctly
preparing it for another season will assure many miles
and hours of trouble-free snowmobiling. Arctic Cat
recommends the following procedure.
CAUTION
If the gas in the carburetor float chambers was not
drained prior to storage, the carburetors must be
cleaned before starting the engine.
1. Clean the snowmobile thoroughly. Polish the exterior of the snowmobile.
2. Clean the engine. Remove the cloth from the
exhaust system. Check exhaust system and airintake silencer for obstructions.
3. Inspect all control wires and cables for signs of
wear or fraying. Replace if necessary. Use cable
ties or tape to route wires and cables away from
hot or rotating parts.
4. Inspect the drive belt for cracks and tears. Check
belt specifications. Replace if damaged or worn.
Install the drive belt.
NOTE: If the old belt is worn but in reasonable
condition, keep it in the tool box as a spare in case
of emergency.
90
5. Inspect the in-line fuel filter and replace if necessary. Inspect all fuel hoses for deterioration or
cracks; replace if necessary. Make sure all connections are tight.
6. Inspect the entire brake system (fluid level, pads,
etc.), all controls, headlight, taillight, brakelight,
ski alignment, ski wear bars, and headlight aim;
adjust or replace as necessary.
7. Inspect the spark plugs. Replace, gap, or clean as
necessary.
8. Adjust the track to the proper tension and alignment.
NOTE: Prior to tipping the snowmobile on its
side, apply the brake and set the brake lever lock.
9. Check air pressure in the front ski shocks.
10. Adjust the carburetors, throttle cable, and choke
cable.
! WARNING
Be sure to tighten the swivel adapter jam nuts
securely. If a jam nut isn’t tightened, the adjuster can
rotate out of the carburetor cap causing the throttle
slide not to return to the full-closed position.
11. Tighten all nuts, bolts, and cap screws making sure
all calibrated nuts, bolts, and cap screws are tightened to specifications.
12. If not done during preparation for storage, lubricate the front and rear suspension and spindles
with an all-temperature grease.
