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.

3. Carefully position Saddle of Jack (Fig. 1) under the
vehicle manufacturer’s recommended lifting point. If
equipped, the Elevating Screw can be used to alter the
height of the jack’s saddle; it is adjusted by turning the
saddle clockwise or counterclockwise. (See vehicle
manufacturer’s owner’s manual for location of frame
lifting point when lifting only one wheel, and frame lifting
points when lifting entire front or rear end of vehicle.)

4. Pump the Handle until the top of the Jack’s Saddle
has nearly reached the vehicle lifting point.
Note: The Jack should be positioned at 90° to the
vehicle’s lifting point to ensure the Jack’s Saddle
and vehicle lifting point are in alignment. If not,
reposition the Jack before lifting the vehicle.

5. To lift the vehicle, pump the Handle of the Jack.
Use smooth, full strokes for best results.
Setup and Operation
6. Once the vehicle is raised, slide a jack stand of
appropriate capacity (not included) under the
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.
Attaching the Handle
1. Insert the Handle into the Handle Socket.
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 captured between the outer
lugs of both jack stands. Use a matched pair of jack stands
per vehicle to support one end only. Use 1 pair per vehicle
only. Failure to do so may result in sudden loss of load,
which may cause personal injury and/or property damage.
2. Turn Handle clockwise until Handle bases
is securely threaded into Socket.
Bleeding
1.
Loosen the Oil Fill Screw (Fig. 2).
2. Insert the Handle into the Release Valve.
3. Turn the Handle (Fig. 1) counterclockwise to open valve.
4. Insert the Handle into the Handle Socket. Pump
the Handle (Fig. 1) up and down quickly for several
times to purge the air from the system.
5. Tighten the Oil Fill Screw (Fig. 2).

Inspection, Maintenance, & Cleaning
sure that they lock securely into position.
Procedures not specifically explained
in this manual must be performed
only by a qualified technician.
Note: Always set both Jack Stands at the same height.

the vehicle onto the saddle(s) of the jack stand(s).
Then, turn the Handle firmly clockwise to close it.
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.
Lowering
1. Carefully remove all tools, parts, etc.
from under the vehicle.
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. Position the Saddle under the lifting point. Turn the
Release Screw firmly clockwise and pump the Handle
to raise the vehicle slightly above the saddles of the
jack stands. Then lower the Jack Stand Saddles to
their lowest position and carefully remove jack stands.
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 2.
3. Slowly turn the Handle counterclockwise (never more
than two full turns) to lower the vehicle onto the ground.
4. Lower the Jack completely. Then, store in a
safe, dry location out of reach of children.
3. Change hydraulic oil at least once every three years:
a. With the Jack fully lowered, remove the Oil
Fill Screw on the side of the Hydraulic Unit.
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 just begins to run out of the oil fill hole.
d. Open the Release Screw 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.
4. 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.
