air bound system is a ram that does not rise smoothly. In some extreme case of an air bound system, air can be purged by following this
procedure:

b. Repeat step “a” several times until all air is purged from the system.
OPERATING INSTRUCTIONS
This is the safety alert symbol used for the OPERATING INSTRUCTIONS section of this manual to alert you to potential
personal injury hazards. Obey all instructions to avoid possible injury or death.
IMPORTANT: Before attempting to raise any vehicle, check vehicle service manual for recommended lifting surfaces.
1. Become familiar with the identification and function of the operating jack components.
a. The ram
(#32)
is the shaft that comes out of the jack when you rotate the air lever to the right.
b. The ram
(#32)
is equipped with an extension screw which can be unscrewed to extend from the ram if there is not enough hydraulic
stroke to raise the load to the desired height. If additional height is required, extension adapters can be inserted in the hole on top of
the extension screw.
c. Larger diameter saddles can be inserted in the extension screw when requiring a larger diameter saddle surface.
2. Chock the vehicle's tires that will not be lifted off the ground prior to lifting the vehicle and if available, apply the emergency brake or any
other method of braking.
3. Position the jack at the designated lift point. Estimate the required ram travel to raise the vehicle to the desired height. If the desired
vehicle height exceeds the entire ram travel, unscrew the extension screw to make up the difference and add an extension adapter if
necessary.
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. Withthejackintheloweredposition,pushthejackunderthevehicle.IMPORTANT:Usethevehiclemanufacturer'srecommendedlifting
procedures and lifting points before lifting loads.
6. Inmostcases100psiginputairpressure(donotexceed200psig)willliftthemaximumcapacityloadnottoexceed22tons.Rotatethe
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.

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
