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.
IMPORTANT: Any jack found to be defective as a result of worn parts due to lack of lubrication, or hydraulic system
contaminated with water, rust and/or foreign materials is not eligible for warranty consideration.
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 the
threads on the extension screw. 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.
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 qualified hydraulic repair personnel who are familiar with this
equipment. Authorized Service Centers are recommended. 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 label clean and readable. Use a mild soap solution to wash external surfaces of the
jack but not any moving hydraulic components.
5.
Do not attempt to make any hydraulic repairs unless you are a qualified hydraulic repair person that is familiar with this equipment.
