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.
IMPORTANT: The number one cause of jack failure in air/hydraulic jacks is dirt and moisture in the air motor and/or hydraulic
system. The shop air supply should be equipped with water and dirt filter traps that should be emptied or cleaned according to a
monthly maintenance schedule. An in line oil lubricator will extend the life of air/hydraulic jacks. Inoperable jacks caused by poorly
equipped or maintained shop air systems are not eligible for warranty consideration. Contaminants can also enter the air/hydraulic
system when the shop air line is disconnected from the jack air line and the line is dropped on the floor. Contaminants in the air
couplers, once reconnected, will be driven into the system.
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 or grit 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.
IMPORTANT: Any jack found to be defective as a result of worn parts due to lack of lubrication or air/hydraulic system contaminated with
water, rust and /or foreign materials from the air supply or other outside source 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 preformed 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.
6. Any hydraulic repairs within the warranty period must be performed by an authorized service center.
