G 1.
Service
Correct maintenance at the right time is essential for
reliable operation of the tractor. Maintenance costs are
small compared with repair costs resulting from lack of
maintenance. The most important measures are those
which you carry out yourself which include lubrication and
various checks and adjustments.
The service intervals shown apply for normal operating
conditions but in more severe conditions servicing should
be carried out more frequently.
Cleaning the tractor
General cleaning instructions
Protect environment following the following environment
orders.
The washing place must have a separator outlet when
using some detergents.
It is best to wash the new tractor for the first time during
the first week of the start---up. Never rub back and forth.
General instructions
concerning oil checks and oil
filling
G 1.1.
Note: Do not wax the paintwork of the new tractor before
the initial washing.
Do not let the tractor run during washing.
--- Always stop the engine before starting work.
--- Apply the parking brake to ensure the tractor cannot
move. If the ground is uneven the wheels should be
blocked.
--- Wash down the tractor first so that the work can be
done easily and quicker, cleaning instructions see (point
G 1.2.).
--- Always observe the utmost cleanliness in all
maintenance work. Thoroughly wipe off filler caps and
plugs as well as surrounding parts of the tractor before
filling up with fuel or oil.
Inspect the oil and filters when changing. Large amounts
of dirt (e.g. heavily clogged filters) can point to a fault
which could cause extensive and costly repairs if not
corrected in time.
--- When carrying out checks the tractor should stand on
level ground.
--- Levels should be checked in the morning when the oil is
cold and has had time to run down to the bottom of the
unit concerned.
--- When changing the oil, bear in mind that the oil can be
very hot when it drains from the tractor.
--- Avoid touching the exhaust manifold, turbocharger and
other hot parts of the engine.
--- Keep the engine surfaces clean in order to avoid the risk
of fire.
--- The fuel, lubricating oil and coolant cause irritation to
skin if in contact for long periods.
--- After completion of service work replace all safety
covers etc.
--- Waste oil, liquid waste, oil filters and batteries should be
handled carefully and disposed of properly.
Greasing lubricating points fitted with
grease nipples
--- Always clean the grease nipples before applying the
grease gun.
--- Apply grease through the nipples until clean grease
oozes out (unless otherwise instructed).
--- Wipe away superfluous grease which has been pressed
out at the lubricating point.
--- Preferably carry out lubrication with bearing points and
joints unloaded and with the bearings in different
positions.
G 1.2.
When washing do not use special nozzles (t.g. turbo nozzle). Keep the nozzle of the pressure washer at least 30
cm from the sealing points and paint work. The temperature of the washing water may not be higher than 50˚C.
Follow also the instructions of the manufacturer!
When washing the cabin sides do not let the water get to
the cabin air filter (in the side plate, usually on the left).
Do not wash the inside of the cab with a pressure washer
or running water. Do not point the pressure washer towards to the electrical equipment, electrical connectors,
lead---through points, bearings, seals and locks. Use lower pressure, 65 bar / 940 psi) and point the water jet diagonally to the above points. Do not point the pressure
washer towards the radar sensor (distance min. 1m and
the max pressure 65 bar / 940 psi).
When using the so---called cold fat remover, do not keep
the tractor in sunshine, the paintwork must not be hot
otherwise the hot paintwork may be damaged.
After washing grease the lubricating points, the joints and
bearings must be lubricated with oil. Wax the painted surfaces.
Engine compartment
Keep the engine surfaces clean in order to avoid the risk
of fire. Do not wash the hot engine, fire risk.
Radiator honeycombs
Clean all the radiator honeycombs regularly using
compressed air or by flushing with water (according the
maintenance program).
Bellows of front axle suspension (air---suspend front
axle)
To ensure correct function of the front axle suspension,
the dirt in the bellows of the suspension and in the housing have to be occasionally removed (detach the housing, if necessary).
Keep the pressure washer nozzle during washing at distance of at least 30 cm from the bellows. The temperature
of the washing water may not be higher than 50 C. Do not
---116---
use special nozzles when washing (Turbo nozzle).
G 1.4.
Cleaning the polycarbonate windows
If the cab has the polycarbonate windows clean them according to the following instructions for keeping the windows bright as long as possible:
--- Clean the stains by wiping using a detergent or plenty
of water. Never rub back and forth.
--- Never use the side window wiper on a dry window.
--- Ensure that there is enough fluid in the washer reservoir.
--- Never clean the side window using a sharp tool like an
ice scraper.
--- Never use an abrasive detergent.
--- Do not point the pressure washer towards the side seals
or lead---through seals because the possible detergent
may reach the uncoated glass parts. However the coated window withstands well different detergents.
G 1.3.
Lubrication and maintenance
schedule
NOTE: All intervals are counted from zero hours on the
hour recorder. For example, the 500 hours service is
carried out after 500, 1000 hours etc. even if the measures
have been carried out at the 100 hours service.
Example: The 1000 hour service contains all items
mentioned under the 10 hr/daily and the 50 hr/weekly
checks as well as the 500 hr service.
Service inspection (after 100
hours)
Your dealer gives a cost---free service inspection
(excluding oil and filter costs) to all new tractors after 100
hours running. The service procedure is as follows:
20 Engine
--- Change engine oil and filter
--- Change prefilter, fuel system
--- Change fuel filter
40 Power transmission

ISO 15380 class HEES (synthetic esters) bio oils can be used as transmission and hydraulic oil. The oil must fulfil the
technical requirements of tractor transmission oil. The bio oil cannot be mixed with mineral oil.
IMPORTANT: The bio oil must not be mixed with other oils, for example when filling or using the machines. The bio oil
can be hazardous to the environment and it must be destroyed properly. Follow the instructions on the package and the
instructions of the local waste management authorities.

G 2.2.3.
IMPORTANT: To mix fuel with any admixing materials is
not allowed.
G 2.2.1.
Fuel
--- The properties of light fuel oil that is only intended for
warming use do not meet the requirements of modern
diesel engines and cannot be used as fuel.
--- In particular, distributor---type injector pumps require the
fuel to have sufficient lubricity, because they do not
have oil lubrication in the same way as typical multi---element pumps. Adding oil to diesel fuel is not recommended, because it causes carbon build---up, and if oil
is mixed with even a small amount of water it will clog
the filter.
--- Additionally, various fuel quality requirements imposed
by taxation and seasonal changes have to be taken into
consideration.
G 2.2.2.
EN ISO 3104
Fuel storage
--- Storing and distributing fuel must be arranged in conditions where no water or impurities can enter the storage
tanks. The storage tanks must be installed in a slanted
position, so that water and impurities are collected at
the opposite end from the suction pipe of the pump.
The suction pipe of the pump should not reach the bottom of the tank.
--- Water must be periodically drained from the tank in
order to prevent problems. Refueling at the same time
the tank is being refilled must be avoided without exception.
--- When the tank is filled with winter---quality fuel in good
time, the engine is guaranteed to run flawlessly during
the cold season.
Filter system
--- The engine’s standard filter system gives sufficient
protection for the injection system from impurities that
can be present in well---tended distribution systems.
--- The control of distributor---type injection pumps is
based on internal pressure, which will drop if the fuel
system is clogged. If the pilot pressure drops too low,
engine power is reduced, smoke increased and starting
becomes more difficult. Additionally, water in the injection system will destroy it in a very short time. For this
reason, the water trap and the filters must always be
serviced according to the specified amount of running hours.
--- It is also important always to use original Valtra (or Sisu
Diesel) fuel filters. They guarantee sufficient filtration,
preventing impurities from damaging the fuel system.
There are many cheap filter kits (so---called pirates) on
the market, with lower quality and performance in order
to minimise the cost. Among other things, the quality
and amount of filter paper are often insufficient. There
are also often dangerous defects in the basic structure
that may cause expensive damage even in a short
period of time.
G 2.2.4.
Biodiesel fuel
The only possible alternative fuel to use is RME
(Rapeseed Methyl Ester) Biodiesel according to European
norm EN 14214 or US norm ASTM D6751. When using
Biodiesel the engine capacity is almost the same as using
diesel fuel.
In Tier 3 SisuDiesel engines with Common Rail fuel
injection system only max 20% dilution of Biodiesel (B20)
is allowed.
---119---
G 3.
Grease
Always use the following greases in Valtra tractors. Each
point requires it own type of grease.
Valtra Grease, NLGI2
Universal grease
Lithium ---based universal grease. Is suitable for greasing all heavy machines.
---25˚ ... +130˚C

G 4.
Maintenance schedule
PERIODICAL MAINTENANCE---schedule (according to
operator’s manual) is recommended for all tractors and
specially for tractors, which have more than 1000 running
hours in one year. The periodical maintenances from 50
hours onwards can also be ordered from the authorized
workshop. In that case the periodical maintenance is
carried out by Valtra authorized and trained service
personnel.
Observe when doing the services that if the tractor is
equipped with extra equipment like towing device, air
condition, air pressure brakes etc. the periodical
maintenances and checks for them must be carried out.
The extra equipment which needs servicing is given in the
end of this manual in section ”K”.
YEARLY MAINTENANCE---schedule should be carried
out by an authorized workshop, but for tractors which
have under 1000 running hours in one year the operator
has to carry out the normal service routines according to
the following table (like daily and weekly periodic
maintenance).

General
Periodic maintenance for the extra and alternative
equipment are in section K, after each extra equipment.
IMPORTANT: Before the maintenance and repair work of
the tractor, loosen the removable parts and clean the environment carefully. Waste oil, liquid waste and brake oil
has to be destroyed properly. Follow the instructions in
the package and the instructions of the local waste management authorities.
The maintenance of the tractor has to be done according
to the periodic maintenance instructions to minimize the
environmental hazard.
NOTE: Clean the tractor before maintenance. Instructions
for cleaning see point G on page 116.
--- After every 1000 hours
--- After 5 cleanings, when the indicator light for the air
cleaner has illuminated 5 times
Change safety air filter (2):
--- At least once a year
--- After every 1000 hours
Unless it is necessary do not open the cover of the air
cleaner housing. Only associated with the situations
mentioned before. During the maintenance check, that the
cover of the housing, pipes and unions are in good
condition.

Change air filter (1):
Always stop the engine before cleaning. A blockage of the
air filter is indicated by a change of the engine beat,
smoky exhaust and reduction of engine power.
--- Check the inside of the air cleaner housing and the inlet
pipe. Dirt on these parts indicates that the filter element
is defective or has not been fitted properly.
--- Clean the filter element with compressed air, max.
pressure 500 kPa (5 bar = 73 lbf/in2), or with an
effective vacuum cleaner.
IMPORTANT: The filter element must not be cleaned
more than 5 times, after which it must be replaced. The
filter must be changed every 1000 hours in accordance
with the maintenance requirement:
--- Hold the filter element up against the light and inspect
the element.

Check, that there are no leakages.
IMPORTANT: The coolant pump is provided with a
drainage hole on its underside. This hole must not be
blocked. If coolant drips out of the hole, the pump seal is
faulty and should be changed immediately. There may be
slight leakage on a new engine before the pump has been
run in.
H 2.2.1.
Freezing point of coolant
Check the freezing point of the coolant at the beginning of
the cold season. If the freezing point is too high, drain off
some of the coolant and top up with anti---freeze. Run the
engine for a while until the anti---freeze has been mixed in,
then re---check the freezing point of the coolant. Drain the
cooling system completely every second year and refill
with new coolant.

The battery can be pulled out in the battery casing to make the maintenance easier. Lock the casing after maintenance.
NOTE: If the water in the battery evaporates too quickly, it
may be a sign that the charging voltage is too high. Keep
the battery clean and dry on the outside. Protect the pole
studs and the cable terminals with grease.
IMPORTANT: During the cold season it is important that
the engine is allowed to run for a while after topping up
with distilled water, otherwise the water may freeze before
it has had time to mix with the battery acid.
Also check cables and battery terminals and clean them if
necessary.
After service fasten the covers and the steps.

--- Top up with distilled water if required.
--- Under no circumstances should you attempt to
replenish the battery acid yourself.
--- Never use a naked flame to check the level of the
electrolyte.
It is recommended that the changing of tyres and wheels
is carried out in a professional tyre workshop which is
equiped to handle this type of work.
DANGER: When welding the discs the tyre
must be away from the rim/ disc, DANGER
OF EXPLOSION!
When mounting the tyre on the disc the pressure limit is

filter is blocked. This can be checked by disconnecting
the pressure sensor wires and running the engine. If the
indicator lamp does not light now, the fault is in the return
filter. Then only the return filter need be changed.
--- Fit a suitable container under the filter and clean the

Low pressure circuit
The fuel system bleeds air automatically due to the electric feed pump. If the engine is not restarted, air is bled
from the fuel system by holding the ignition switch in position 1 when the fuel pump is rotating for one minute at a
time. If the engine fails to start, move the ignition switch
back to the STOP position, bleed again in the position 1
and start the engine.
High pressure circuit
T I39
In Common Rail engines let the pump run for 30 seconds
and the start for 10 seconds in turn (the high pressure
circuit bleeds only when the high pressure pump is rotating).
WARNING: The fuel system connectors are
not allowed to be opened when the engine
is running and not in 30 seconds after
switching off the engine. The pressure in
injection type of engines (CR models) is
over 1000 bar. If the jet of the high pressure
fuel contacts your skin, the fuel penetrates
the skin causing serious injuries. Contact
your doctor immediately. Only an authorized
person is allowed to repair the fuel system.
The air cleaner prevents dust and other particles from
entering the engine with the induction air. Engine wear is
largely dependent on the cleanliness of the induction air,
so it is very important to check the air cleaner regularly
and to maintain it correctly.
IMPORTANT: The safety filter (2) behind the main filter (1)
must not be cleaned but must always be changed
according to the maintenance schedule. The purpose of
the safety filter is to prevent damage to the engine if the
main filter should fail.

always be changed.
IMPORTANT: Never clean or remove the air filter unless it
is absolutely necessary. When removing the air filter there
is always the possibility that dirt may enter the induction
system of the engine.
Cleaning of the main filter
Use clean and dry compressed air with a max. pressure of
500 kPa (5 bar = 72.5 lbf/in2).

The following action should be taken to make sure that
the cooling system functions correctly:
--- Check the coolant level (see maintenance point 2 on

--- Clean the radiator honeycomb externally using
compressed air or by flushing with water.

1. First, direct the air flow from the rearside of the filter
forward into the air direction. Do not hold the nozzle
closer than 3---5 cm (1.2 --- 2.0 in).
2. Then, direct the air flow from the front side of the filter
and after that from the rearside of the filter again.
3. Check the filter and its sealing surfaces using a
flashlight. Change the filter if any holes or other defects
are discovered.
IMPORTANT: See maintenance on page 123.
Coolant
The cooling system is filled with a mixture of water and
anti---freeze agent on delivery. The anti---freeze agent also
prevents rust from forming in the cooling system.
However, the anti---rust properties of the agent diminish
with time, so it is important to change the coolant at
regular intervals. A suitable mixture is one part anti---freeze
agent to one part water, but the manufacturer’s directions
should always be followed (see maintenance point 32).

Do not connect any additional electrical equipment, as
this may damage components of the existing electrical
system.
Battery checks and
maintenance
I 2.3.1.
Welding
IMPORTANT: The battery leads (negative first), the alternator wiring and the engine management multipoleconnectors (3 pcs) have to be disconnected before arc welding is carried out on the tractor or an implement which is
attached to it.
The engine control unit (1) is placed:
A6181---114
--- Check the charge in the battery using a hydrometer
(”acid tester”). The density of the electrolyte should be
at least 1,23.
--- Make sure that the fan belt (belts) are always correctly
tensioned.
--- Keep the battery clean. It can be washed with lukewarm
water after removal from the tractor (always disconnect
the negative lead first).
--- Also clean the pole studs, the cable terminals and the
battery retainer thoroughly. Wash off oxidized spots with
water. Wipe the outside of the battery when it is clean,
and coat the pole studs and the cable terminals with
petroleum jelly.
--- Refit the battery (always connect the positive lead first).
DANGER: Avoid sparking or naked flames
near the battery. The battery gives off
explosive hydrogen gas!
Battery electrolyte is corrosive.

Alternator
T I40
The tractor has a negative---grounded alternator which
can easily be damaged if incorrect connections are made
in the electrical system. For example, connection of the
battery with wrong polarity can burn out the alternator or
rectifier. The electrical charging circuit must not be broken
when the engine is running.
I 2.3.
Safety precautions for the
electrical system
--- Always connect the battery with the correct polarity.
--- Disconnect the negative lead of the battery first and
connect it last.
---Never open the charging circuit while the engine is
running.
--- The engine control unit (1) is placed in the left side of
the engine. The cover of the connectors must first be
disconnected. The demountable connectors are three.
All the connectors (2) will be disconnected and connected
in the same way. Open the connector locking device (3) to
disconnect the connector, then the connector opens.
When re---connecting turn the locking device back to the
locking position.
IMPORTANT: Never run the engine with the alternator
disconnected.
---145---
I 2.4.
Fuses
T I52
The fuse box, which is positioned under the instrument
panel should always be kept clean. It contains 31 fuses.
The nominal current rating of the fuses is between
5---30 A. If any of the fuses blow, the fault must be traced
and remedied. Fuses must not be replaced with ones of
a higher rating, as this may cause damage to the
electrical equipment. The fuse diagram is placed under
the fuse box (it is shown in the figure above). There is
space for reserve fuses between the fuses.
When you need a continuous electrical supply e.g. to the
implement, illumination etc. power can be taken from the
trailer connection (see page 103). With the implement
control system (optional equipment) electrical power to
the optional equipment can be switched on and off from
the driver’s cab.
Power for optional equipment can also be taken from the
spare fuses or unused optional equipment fuses. A
continuous current source can be connected from the
main current pole of the starter motor (on the models with
main circuit breaker, current is switched off with main
switch) through the new fuse.

Headlight adjustment
Correct adjustment of the headlights is very important
when running on the public road.
Headlight adjustment can be carried out quickly and
accurately by using an optical headlight adjusting unit. If
no optical instrument is available, adjustment can be done
as follows:
Check before adjusting the headlight that the tractor
loading is normal and tyre pressures are correct. With
dipped---beam switched on, the cutoff edge of the light
pattern should come at height H when the tractor is at
distance L. With full---beam switched on, the distance
between the light points should be B. Any necessary
adjustment is done using the headlamp adjusting screws.
