OPERATING INSTRUCTIONS
4. Lock the handle in a position that will not interfere with the vehicle when raised or lowered. Keep the handle in that locked position until the work is
completed and you are ready to remove the jack from use.
5. With the jack in the lowered position, push the jack under the vehicle.
IMPORTANT: Use the vehicle manufacturer's recommended lifting procedures and lifting points before lifting loads.
6. In most cases 100 psig input air pressure (do not exceed 200 psig) will lift the maximum capacity load not to exceed 22-tons. Rotate the air lever to the
right until the top of the ram comes close to the designated lift point. Make sure the designated lift point is flat, parallel to the ground and free from grease,
any kind of lubricant, and debris. Proceed with pumping the jack in order to lift the vehicle to the desired height. During lifting, inspect the position of the
jack in relation to the ground and the ram in relationship to the load to prevent any unstable conditions from developing. If conditions look like they are
becoming unstable, slowly lower the load and make appropriate setup corrections after the load is fully lowered.
7. When the vehicle or load is lifted to its desired height, immediately place safety support stands (jack stands) in their designated locations and adjust the
stands' support columns up as close to the designated vehicle support points as possible. Although jack stands are individually rated, they are to be used
in a matched pair to support one end of the vehicle only. Stands are not to be used to simultaneously support both ends or one side of a vehicle. Rotate the
air lever to the left to lower the vehicle onto the safety support stands (jack stands). Make sure the vehicle is safely supported by the safety support stands'
(jack stands) saddles and not the locating lugs of the saddles. Inspect the relationship of the safety support stands (jack stands) with the ground and the
safety support stand (jack stand) columns and saddles with the vehicle to prevent any unstable conditions. If conditions look unstable, rotate the air lever
to the right to raise the vehicle off the safety support stands (jack stands). Make the appropriate setup changes and slowly and carefully lower the vehicle
onto the safety support stand saddles.
8. After the work is done, rotate the air lever to the right 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.
9. Rotate the air lever to the left to lower the vehicle or load down to the ground.

PREVENTATIVE MAINTENANCE

WARNING
Failure to follow these Preventative Maintenance instructions may result in serious injury or death, and/or property damage.
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, 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 qualified hydraulic repair personnel who are familiar with this equipment. Authorized Service
Centers are recommended.
In order to prevent seal damage and jack failure, never use alcohol, hydraulic brake fluid or transmission oil in the jack.
WARNING
Use hydraulic jack oil only.
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. 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.
