General Operating Instructions

Lifting

Park vehicle on a flat, level, solid, 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, chock the wheels that are not being lifted.

1. Turn the Handle counterclockwise to lower the Jack.
Once the Jack is fully lowered, turn the
Handle firmly clockwise to close it.

2. Carefully position the Saddle of the Jack under
the vehicle manufacturer’s recommended lifting
point. (See vehicle manufacturer’s owner’s
manual for location of frame lifting point.)

3. Pump the Handle until the top of the Jack’s Saddle
has nearly reached the vehicle lifting point. Position
the Saddle directly under the vehicle’s lifting point.

4. To lift the vehicle, pump the Handle of
the Jack. Use smooth, full strokes.

5. Once the vehicle is raised, slide a jack stand of
appropriate capacity (not included) under a proper
lifting point referred to in the vehicle owner’s
manual. Always use two jack stands, position them
at the same point on each side of the vehicle.

WARNING! The rated capacity of jack stands is per
pair, not the individual capacities combined unless
specifically noted on the product by the jack stand
manufacturer. Do not exceed rated jack stand capacity.
Ensure that the vehicle support points are fully seated
in the saddle of both jack stands. Use a matched pair
of jack stands per vehicle to support one end only.
Failure to do so may result in the load suddenly falling,
which may cause personal injury and/or property damage.

6. Center the vehicle’s lifting point(s) on the saddle of
the jack stand(s). Set the jack stand(s) to the same
height according to the manufacturer’s instructions,
making sure that they lock securely into position.

7. Slowly turn the Handle counterclockwise to lower
the vehicle onto the saddle(s) of the jack stand(s).
Then, turn the Handle firmly clockwise to close it.

SAFETYOPERATIONMAINTENANCE SETUP

Lowering

1. Carefully remove all tools, parts, etc.
from under the vehicle.

2. Position the Saddle under the lifting point.
Turn the Handle firmly clockwise and raise
load high enough to clear the jack stands,
then carefully remove jack stands.

3. Slowly turn the Handle counterclockwise
(never more than 1/2 full turn) to lower
the vehicle onto the ground.

4. Lower the Jack completely. Then, store in a
safe, dry location out of reach of children.

5. To prevent accidents, turn off the tool and
disconnect its power supply after use. Clean, then
store the tool indoors out of children’s reach.

Maintenance and Servicing

Procedures not specifically explained in this manual must

be performed only by a qualified technician.

SAFETY OPERATION MAINTENANCESETUP

TO PREVENT SERIOUS INJURY FROM TOOL FAILURE:
Do not use damaged equipment. If abnormal noise or vibration
occurs, have the problem corrected before further use.

Cleaning, Maintenance, and Lubrication

1. Before each use, inspect the general condition
of the Jack. Check for broken, cracked, or bent
parts, loose or missing parts, 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. Before each use, thoroughly test the Jack
for proper operation prior to its actual use.
If the Jack appears not to be working properly,
follow Bleeding instructions on page 4.

3. Change the hydraulic oil at least
once every three years:

A. With the Jack fully lowered, remove the Oil

Filler Plug on the side of the Housing.

B. Tip the Jack to allow the old hydraulic oil

to drain out of the Housing completely,
and dispose of the old hydraulic oil in
accordance with local regulations.

C. With the Jack upright, completely fill the

Housing with a high quality hydraulic oil (not

included) until the oil is 1/4″ below the fill hole.

D. Open the valve by turning the Handle

counterclockwise and pump the Handle
to bleed air from the system.

E. Recheck oil level and re-fill as needed.

F. Reinstall the Oil Filler Plug.

7. Wipe dry with a clean cloth. Then, store the
Jack in a safe, dry location out of reach of
children and other non-authorized people.

Troubleshooting

TO PREVENT SERIOUS INJURY:
Use caution when troubleshooting a malfunctioning jack. Stay well clear of the supported load.
Completely resolve all problems before use. If the solutions presented in the Troubleshooting guide
do not solve the problem, have a qualified technician inspect and repair the jack before use.

After the jack is repaired: Test it carefully without a load by raising and lowering it fully,
checking for proper operation, BEFORE RETURNING THE JACK TO OPERATION.

DO NOT USE A DAMAGED OR MALFUNCTIONING JACK!
