7. After the work is done, close the release knob and depress the air valve until the jack is high enough to remove the vehicle or load from the
safety support stand saddles. Be sure load is stable. If it is not, lower load back onto safety support stands. Make appropriate setup
corrections and repeat the step again. Remove the safety support stands from under the vehicle being very careful not to move the vehicle.
8. Turn the release knob in a counterclockwise direction very slowly and carefully to lower the vehicle or load down to the ground.

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.
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. Jacks found to be defective due to 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. Contact NAPA for replacement labels if not readable.
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.
