PREVENTIVE MAINTENANCE

WARNING
Failure to follow these Preventive Maintenance instructions may result in serious injury or death, and/or property damage.
1. Always store the jack in a well protected area where it will not be exposed to inclement weather, corrosive vapors, abrasive dust, or any other harmful
elements. The jack must be cleaned of water, snow, sand, grit, oil, grease or other foreign matter before using.
2. The jack must be lubricated periodically in order to prevent premature wearing of parts. A general purpose grease must be applied to all zerk grease
fittings, caster wheels, front axle, elevator arm, handle base pivot bolts, release mechanism and all other bearing surfaces. Worn parts resulting from
inadequate or no lubrication are not eligible for warranty consideration.
3. It should not be necessary to refill or top off the reservoir with hydraulic oil unless there is an external leak. An external leak requires immediate repair
which must be performed in a dirt-free environment by an authorized service center.
In order to prevent seal damage and jack failure, never use alcohol, hydraulic brake fluid or transmission oil in the jack.
WARNING
Use hydraulic jack oil only.
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.
INSPECTION
WARNING
Failure to follow these Inspection instructions may result in serious injury or death, and/or property damage.
Visual inspection should be made before each use of the jack, checking for leaking hydraulic fluid and damaged, loose or missing parts. Each jack must be
inspected by a manufacturer's repair facility immediately if subjected to an abnormal load or shock. Any jack which appears to be damaged in any way, is found
to be badly worn, or operates abnormally MUST BE REMOVED FROM SERVICE until necessary repairs are made by a manufacturer's authorized repair facility.
It is recommended that an annual inspection of the jack be made by a manufacturer's authorized repair facility and that any defective parts, decals or warning
labels be replaced with manufacturer's specified parts. A list of authorized repair facilities is available from the manufacturer.
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-
2019 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
1. Unit will not lift rated load.
2. Unit will not sustain rated load or feels "spongy" under rated load.
3. Unit will not lift to full height.
4. Handle tends to raise up while the unit is under rated load.
5. Unit still does not operate.
