OWNER'S MANUAL
PREVENTATIVE MAINTENANCE
This is the safety alert symbol used for the PREVENTATIVE MAINTENANCE section of this manual to alert you to potential personal
injury hazards. Obey all instructions to avoid possible injury or death.
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 cleared of water, snow, sand or grit 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. See page 6 for lubrication instructions.
3.
It should not be necessary to refill or top off the reservoir with hydraulic fluid 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.
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.
INSPECTION
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-
PALD 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 load.
2. Unit will not sustain load or feels "spongy" under load.
3. Unit will not lift to full height.
4. Handle tends to raise up while the unit is under load.
5. Unit still does not operate.
