TROUBLESHOOTING
Assuming the source of compressed air is functioning properly and supplying air pressure to the jack's air valve, the only causes for a jack's
inability to lift a load would be the jack's air valve is blocked or its ram seal is damaged. In either case, the jack must be taken to an
authorized service center for repair.
WARRANTY
Please contact your local NAPA Auto Parts Store for details on warranty.
PREVENTATIVE MAINTENANCE (continued)
IMPORTANT: Water can enter the jack's cylinder through the shop's compressed air system or the top of the jack where the ram is
located. Water can enter the top of the jack if left out in inclement weather or used near a wash rack or place where water/fluid pres-
sure is used to clean the underside of vehicles or other components. Water in the jack's cylinder can cause the interior wall of the
cylinder to rust and cause damage to the ram's air seal rendering the jack inoperable. An inoperable jack caused by rust or contami-
nation is not eligible for warranty consideration. A jack believed to contain water must be serviced at an authorized repair center as
soon as possible.
2. The jack must be lubricated periodically in order to prevent premature wearing of parts. A general purpose grease must be applied
to the axle where the wheels rotate and a very thin coat on the ram. Do not lubricate any portion of the lift saddle and make sure the
saddle is free from grease, any kind of lubricant, or debris before using the jack. Use a high quality grease to lube the cylinder wall.
3. An air leak requires immediate repair which must be performed in a dirt-free environment by qualified hydraulic repair personnel
who are familiar with this equipment. Authorized Service Centers are recommended.
4. Every jack owner is responsible for keeping the jack label clean and readable. Contact NAPA for a replacement label if your jack's
label is not readable.
5. Inspect the jack before each use. Do not use the jack if any component is cracked, broken, bent, shows signs of damage, or leaks
air. 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. Do not attempt to make any repairs unless you are a qualified repair person that is familiar with this equipment.
