OPERATING INSTRUCTIONS
IMPORTANT: Before attempting to raise a vehicle, check vehicle
service manual for recommended lifting surfaces.
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 until 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 recommended lift areas
that provide stable support for the raised vehicle.
2. To lower load: Open release valve VERY SLOWLY (by
turning handle counterclockwise). When release valve is
opened, saddle and load will be lowered. Lower the vehicle
slowly so as not to shock load the jack stands. Once repairs
are completed, raise vehicle enough to remove jack stands.
Lower vehicle very slowly.
CAUTION: Keep hands or feet away from the hinge mechanism
of the jack.
PROPER STORAGE
It is recommended that the jack be stored in a dry location with all wheels touching the ground on a relatively level surface.
TROUBLESHOOTING
Important: Service jacks are self-contained devices used for lifting, but not sustaining, a partial vehicular load. In accordance with
ASME-PALD standard, section 10-4.1.2 Load Sustaining Test: "A load not less than the rated capacity...shall not lower more than
1/8" (3.18mm) in the first minute, nor a total of .1875" (4.76mm) in 10 minutes." Leak down within this range is considered
normal operation and is NOT a warrantable defect.

MAINTENANCE
IMPORTANT: When adding or replacing hydraulic fluid, always
use a quality hydraulic fluid. DO NOT use brake fluid, alcohol,
glycerine, detergent motor oil, or dirty oil as improper fluid can
cause serious internal damage to jack.
To add hydraulic fluid: With saddle fully lowered and jack
on level ground, remove breather. The hydraulic fluid
should just cover the surface of the internal cylinder visible
through the hole. Do not overfill. Replace breather. If low,
add hydraulic fluid as needed.
Maintenance and Inspection: The owner and/or user must
maintain and inspect the jack in accordance with the
manufacturer's instructions.
LUBRICATION
All moving joints require lubrication on a regular maintenance
schedule. 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. Grease all lift arm linkages, front wheels
and rear casters.
SOLUTION SOLUTION
The release valve is not closed. Turn the valve clockwise tightly.
If this does not work, remove handle, lubricate handle
receptacle and handle end, then retry.
Low on hydraulic fluid. Refill the jack to the correct level of
hydraulic fluid.
Pump seals or back-up ring may be defective. Clean hydraulic fluid
passages, replace seals and refill hydraulic fluid.
(Must be serviced by qualified service center)
The hydraulic system has trapped air.
Open the release valve, pump handle rapidly (4) full strokes
to purge air, close release valve.
Return spring is broken or linkages are binding. Replace spring if
broken. Grease pivot shaft and all lift arm linkages.
Discharge ball is not sealing hydraulic system and oil may be dirty.
Manually flush hydraulic system. Open the release valve, as required,
to raise and lower the lift arm. Manually raise
and lower lift arm.
