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 and jack stands in a well protected area where they will not be exposed to inclement weather, corrosive vapors,
abrasive dust, or any other harmful elements. The jack and stands must be cleaned 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, lift 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 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 and jack stand 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 and jack stands before each use. Do not use the jack and jack stands 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 and stands, checking for leaking hydraulic fluid and damaged, loose or
missing parts. Jack and stands must be inspected by a manufacturer's repair facility immediately if subjected to an abnormal load or shock.
Any jack or stands which appear to be damaged in any way, are found to be badly worn, or operate 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 and stands 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 and stands be stored in a dry location with all wheels and stand legs touching the ground on a relatively
level surface.
OWNER/USER RESPONSIBILITY
The owner and/or user must have an understanding of the manufacturer's operating instructions and warnings before using the jack and
stands. Personnel involved in the use and operation of equipment shall be careful, competent, trained, and qualified in the safe operation
of the equipment and its proper use when servicing motor vehicles and their components. Warning information should be emphasized and
understood. If the operator is not fluent in English, the manufacturer's instructions and warning shall be read to and discussed with the
operator in the operator's native language by the purchaser/owner, making sure that the operator comprehends its contents. Owner and/or
user must study and maintain for future reference the manufacturers' instructions. Owner and/or user is responsible for keeping all warning
labels and instruction manuals legible and intact. Replacement labels and literature are available from the manufacturer.
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.
