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.
