Troubleshooting; Warranty - Napa Carlyle Tools 791-6620E Operating Manual & Parts List

IMPORTANT: The number one cause of jack failure in air/hydraulic jacks is dirt and moisture in the air motor and/or hydraulic system.
The shop air supply should be equipped with water and dirt filter traps that should be emptied or cleaned according to a monthly
maintenance schedule. An in line oil lubricator will extend the life of air/hydraulic jacks. Inoperable jacks caused by poorly equipped or
maintained shop air systems are not eligible for warranty consideration. Contaminants can also enter the air/hydraulic system when
the shop air line is disconnected from the jack air line and the line is dropped on the floor. Contaminants in the air couplers, once reconnect-
ed, will be driven into the system.
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 wheels, 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 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 NAPA
Hydraulic Jack Oil #765-1541.
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 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.
OWNER/USER RESPONSIBILITY
The owner and/or user must have an understanding of the manufacturer's operating instructions and warnings before using this jack.
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.
