OPERATING MANUAL & PARTS LIST FOR 791-7200 E
PREVENTATIVE MAINTENANCE (continued)
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. Lubricate moving parts, excluding the telescopic rams, monthly with a general purpose grease.
IMPORTANT:
any jack found to be defective as a result of worn parts due to insufficient or lack of lubrication is 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 qualified hydraulic repair personnel who are
familiar with this equipment.
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. Do not attempt to make any hydraulic repairs unless you are a qualified hydraulic repair person that is familiar with this
equipment. Repairs must be performed by an authorized service center.
