ASSEMBLY INSTRUCTIONS
1. Remove 2-piece handle from box. Insert narrow portion
of top section (17) into bottom section (15) and secure
with bolt (16) provided.
2. Then, slightly press down on the handle yoke
assembly to release pressure on the handle yoke
assembly retainer and remove retainer. This will allow
handle yoke to be raised to operating position.
3. Grease handle receptacle and insert slotted end
of handle into place. Tighten set screw (13) to secure
handle.
OPERATING INSTRUCTIONS
BEFORE USE:
Air may become trapped in the hydraulic system during
transit. To purge air:
1. Open release valve by turning handle counterclock-
wise.
2. Pump handle rapidly 4 full strokes. This will expel air
that may have entered oil passages during transit.
3. Close release valve by rotating handle clockwise and
pump handle.
4. If lift arm is raised, jack is ready for use. If not, repeat
this procedure.
IMPORTANT:
Before attempting to raise any vehicle, check
vehicle service manual for recommended lifting surfaces.
OPERATION:
1. To Raise Load: Close release valve tightly (by turning
handle clockwise). DO NOT OVERTIGHTEN. Position
jack under load so that saddle will contact load firmly and
load is centered so it cannot slip. Operate jack handle un-
til saddle approaches the load. Once again, check to see
that saddle is correctly positioned. Raise load to desired
height. Place jack stands of appropriate capacity under
the vehicle. DO NOT CRAWL UNDER VEHICLE WHILE
LIFTING VEHICLE OR PLACING OR REMOVING JACK
STANDS!
Place jack stands at vehicle manufacturer’s recommend-
ed lift areas that provide stable support for the raised
Vehicle. Once jack stands are positioned, open the
release valve VERY SLOWLY (by turning the handle
counterclockwise).
Lower the load to rest on the jack stands. Then, make
sure that the release valve on the jack is closed tightly
(by turning the handle clockwise).
2. To lower load:
Re-check to make sure release valve is tightly closed.
Then, operate the jack handle until the load is raised
enough to remove the jack stands.
DANGER!
DO NOT CRAWL UNDER VEHICLE WHILE LIFTING
VEHICLE OR REMOVING THE JACK STANDS!
Once jack stands are removed, open release valve very
slowly to lower the vehicle. Lower jack completely so that
the vehicle is securely resting on the ground and that jack
no longer makes contact with vehicle.
CAUTION!
Keep hands or feet away from the
hinge mechanism of the jack.
MAINTENANCE
When adding or replacing hydraulic fluid, always use a
quality hydraulic fluid. DO NOT use brake fluid, alcohol,
detergent motor oil, dirty oil or any fluid other than quality
hydraulic fluid. Improper fluids can cause internal dam-
age to the jack and improper or unsafe operation.
Adding Hydraulic Fluid
With the saddle fully lowered and the jack on level
ground, remove the filler screw. Hydraulic fluid should
be filled to the level of the filler screw hole. If the level is
below this hole, add hydraulic fluid as needed.
LUBRICATION
All moving joints require lubrication often. Lightly grease
saddle post and saddle bottom. Remove handle and
grease the lower end of handle where it rotates in the
handle socket. Using a grease gun, grease the lift arm
pivot shaft grease fitting until grease appears at the end
of the shaft. Oil all lift arm linkages, front wheels and rear
casters.
