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 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 .
