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-PASE 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.” Lowering within this range is considered normal operation and is NOT a warrantable defect.

PROBLEM

ACTION

1. Unit will not lift rated load.

Purge air from hydraulic system by following procedure under 
SETUP.

2. Unit will not sustain rated load or  feels “spongy” under rated load.

Purge air from hydraulic system as above.

3. Unit will not lift to full height.

Purge air from hydraulic system as above.

4. Handle tends to raise up while the unit is under rated load.

Pump the handle rapidly several times to push oil past ball 
valves in power unit.

5. Unit still does not operate.
