GENERAL SAFETY RULES
1.
Keep your work area clean and well lit. Cluttered work areas invite accidents.
2.
Do not operate tools and equipment in explosive atmospheres, such as in
the presence of flammable liquids, gases, or dust. Power tools and equipment create sparks which may ignite flammables.
3.

footing and balance enables better control of the tool in unexpected situations.
7.
Use safety equipment. Always wear ANSI approved safety impact goggles,
safety shoes/boots, and heavy duty work gloves when using this product.
8.
Do not force the tool. Use the correct tool for your application. The correct
tool will do the job better and safer at the rate for which it is designed.
9.
Store idle tools and equipment out of reach of children and other untrained
persons. Tools and equipment are dangerous in the hands of untrained users.
10.
Maintain tools with care. Do not use a damaged tool. Tag damaged tools “Do

WARNING! Do not exceed the maximum lift capacity (1.5 Tons/3,000
pounds) for the Hydraulic Jack. Overloading the Jack could cause serious
personal injury and/or property damage.
2.
WARNING! Jack Stands maximum weight capacity is 3 Tons/6,000 lbs.
when used in pairs. Never exceed this maximum weight capacity. Overloading
the Jack Stands could cause serious personal injury and/or property damage.
3.
This Jack and its Stands are designed for intermittent use only. Do not use
the Jack or its Stands to support a vehicle over extended periods of time. The
duration of the lifting job should be kept as short as possible.
4.
Maintain labels and nameplates on the Jack and its Stands. These carry
important information. If unreadable or missing, contact Harbor Freight Tools for
a replacement.
5.
Prior to using the Jack and its Stands, make sure to read and understand
all warnings, safety precautions, and instructions as outlined in the vehicle
manufacturer’s instruction manual. Always check instruction manual for
proper lifting and support locations.
6.
When lifting only one wheel, make sure to support the load immediately
with one Jack Stand placed under the side of the vehicle being lifted. Align
the Saddle of the Jack Stand directly under the vehicle’s seam (recommended

OPERATING INSTRUCTIONS
NOTE: For additional references to the parts listed in the following pages, refer to the
Assembly Diagrams on pages 11 and 12.
1.
IMPORTANT! Make sure to thoroughly test the Hydraulic Jack for proper
operation prior to its actual use. If the Hydraulic Jack appears not to be
working properly, it may be necessary to purge its hydraulic system of
excess air. To do so, remove the Oil Fill Plug (3C). Assemble the Upper Handle
(6A), Bumper (7A), and Lower Handle (8A) of the Jack. Insert the Lower Handle
into the Handle Yoke (12A) and tighten the Handle Yoke Bolt (10A). Turn the
Handle Assembly clockwise. Apply pressure to the Saddle (28A), and pump the
Handle Assembly slowly several times. The trapped air is pressurized and will be
audible when released in this manner. Once purged of air check the Oil Reservoir (22C) and, if necessary, top off the Oil Reservoir with hydraulic oil. Then,
replace the Oil Fill Plug. Turn the Handle Assembly counterclockwise slowly to
completely lower the Jack. Test the Jack several times for proper operation
before attempting to lift a load. If, after purging, the Jack still does not appear
to be working properly, do not use the Jack until it has been repaired by a
qualified service technician. (See Figures A and C.)

2.
CAUTION! Make sure the vehicle is parked on a flat, level, solid, ground
surface safely away from oncoming traffic. Turn off the vehicle’s engine.
Place the vehicle’s transmission in “PARK” (if automatic) or in its lowest gear (if
manual). Set the vehicle’s emergency brake. Then, block the wheels that are
not being lifted.
3.
Check to make sure the Jack is fully lowered. If not, assemble the Upper Handle
(6A), Bumper (7A), and Lower Handle (8A). Insert the Lower Handle into the
Handle Yoke (12A). Then, turn the Lower Handle counterclockwise to lower the
Jack. Once the Jack is fully lowered, turn the Handle Assembly firmly clockwise.
(See Figure A.)
4.
Carefully position the Saddle (1B) of the Hydraulic Jack under the vehicle
manufacturer’s recommended lifting point. (See vehicle manufacturer’s owner’s
manual for location of seam lifting point when lifting only one wheel and frame
lifting points when lifting the entire front or rear end of the vehicle.)
5.
Pump the Handle Assembly until the top of the Jack’s Saddle (28A) has nearly
reached the vehicle lifting point. NOTE: The Jack should be positioned at 90
degrees to the vehicle’s lifting point to ensure the Jack’s Saddle and lifting point
are in alignment. If not, remove and reposition the Jack before lifting the vehicle.
(See Figure A.)
6.
To lift the vehicle, pump the Handle Assembly (6A, 7A, 8A) of the Jack. Use
smooth, full strokes for best results. (See Figure A.)
7.
Raise the vehicle to just above the minimum height of the Jack Stand. Then,
slide the Jack Stand to the proper lifting points referred to in the vehicle owner’s
manual. Also, if using two Jack Stands, make sure they are on the same point
on each side of the vehicle. (See Figure B, next page.)
8.
Center the vehicle’s lifting point on the Saddle (1B) of the Jack Stand. Pull
up on the Saddle of the Jack Stand until it is just below the contact points on the
vehicle. Next, insert the Lock Pin (3B) through the Outer Tube (2B) and Saddle
to lock the Saddle in place. If using two Jack Stands make sure they are at
the same height. (See Figure B.)
9.
If using two Jack Stands, turn the Handle Assembly counterclockwise slowly to
lower the vehicle onto the Saddles (1B) of the Jack Stands. Do this release
slowly until you are familiar with the rate at which the Jack lowers a load. Then,
turn the Handle Assembly firmly clockwise. (See Figure B.)
10.
If using two Jack Stands, gently rock the vehicle to determine if it is stable on
the Jack Stands. If it is not, raise the vehicle, and reposition the Jack Stands.
CAUTION! When performing this procedure be prepared and stand
clear of the vehicle, as the vehicle can fall off the Jack Stands causing
personal injury and/or property damage.

11.
When the repair work to the vehicle is completed, make sure to remove all tools,
old vehicle parts, etc. from under the vehicle.
12.
Turn the Handle Assembly (6A, 7A, 8A) firmly clockwise, and pump the Handle
Assembly to raise the vehicle slightly above the Saddles (1B) of the Jack Stands.
Then, collapse the Jack Stands and remove them from under the vehicle.
13.
Slowly turn the Handle Assembly (6A, 7A, 8A) counterclockwise (never more
than two full turns) to lower the vehicle onto the ground. (See Figure B.)
14.
Lower the Hydraulic Jack completely. Then, store the Jack and Jack Stands in
a safe, dry location.
INSPECTION, MAINTENANCE, AND CLEANING
1.
Before each use, inspect the general condition of the Hydraulic Jack and Jack
Stands. Check for broken, cracked, or bent parts, loose or missing Lock Pins,
and any condition that may affect the proper operation of the product. If a problem occurs, have the problem corrected before further use.
Do not use damaged equipment.
2.
Change the hydraulic oil at least once every three years. To do so, with the
Hydraulic Jack fully lowered, remove the Oil Fill Plug (3C) on the end of the
Base Plate (5C). Tip the Hydraulic Jack to allow the old hydraulic oil to drain
out of the oil Reservoir (22C) completely, and dispose of the old hydraulic oil in
SKU 91850
For technical questions, please call 1-800-444-3353
PAGE 8
accordance with local regulations. With the Hydraulic Jack upright, completely fill
the Reservoir with a high quality hydraulic oil (not included). Then, reinstall the
Oil Fill Plug. (See Figures A and C.)
3.
Purge the hydraulic system of air occasionally. Occasionally, the Hydraulic
Jack will exhibit signs of excessive air in its hydraulic system such as slow response to pumping, a spongy feeling to the pumping action, and a general lack of
performance. To purge the hydraulic system of air, remove the Oil Fill Plug (3C).
Assemble the Upper Handle (6A), Bumper (7A), and Lower Handle (8A) of the
Jack. Insert the Lower Handle into the Handle Yoke (12A) and tighten the
Handle Yoke Bolt (10A). Turn the Handle Assembly clockwise. Apply pressure to
the Saddle (28A), and pump the Handle Assembly slowly several times. The
trapped air is pressurized and will be audible when released in this manner.
Once purged of air check the Oil Reservoir (22C) and, if necessary, top off the Oil
Reservoir with hydraulic oil. Then, replace the Oil Fill Plug. Turn the Handle
Assembly counterclockwise slowly to completely lower the Jack. Test the Jack
several times for proper operation before attempting to lift a load. If, after purging, the Jack still does not appear to be working properly, do not use the
Jack until it has been repaired by a qualified service technician.
(See Figures A and C.)
4.
When cleaning, use a clean cloth with a detergent or mild solvent. Then, store
the Hydraulic Jack and Jack Stands together in a safe, dry location.
