IMPORTANT:
In order to prevent seal damage and jack failure, never use alcohol, hydraulic brake fluid or transmission oil in the jack. Use
Chevron Hydraulic Oil AW ISO 32 or its equivalent Unocal Unax AW 150.
4. Every jack owner is responsible for keeping the jack labels clean and readable. Use a mild soap solution to wash external surfaces of
the jack but not any moving hydraulic components.
5. Inspect the jack before each use. Do not use the jack if any component is cracked, broken, bent, shows sign of damage or leaks
hydraulic fluid. Do not use the jack if it has loose or missing hardware or components, or is modified in any way. Take corrective action
before using the jack again.
6. Any hydraulic repairs within the warranty period must be performed by an authorized service center.
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.
