OPERATING INSTRUCTIONS

Become familiar with the identification and function of the jack components:

a. The ram (#32) is the shaft that comes out of the jack when you rotate the air lever to the

left.

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.

Apply the emergency brake and use wheel chocks to block all wheels to prevent movement of the

vehicle being lifted.

Connect the quick coupler into a shop air supply hose. In most cases 110-120 PSI air pressure will lift

the maximum rated capacity.

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.

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.

With the jack in the lowered position push the jack under the vehicle. IMPORTANT: Use the vehicle's

manufacturer's recommend lifting procedures and lifting points before starting.

Rotate the air lever to the left 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 or debris. Proceed

with pumping the jack in order to lift the vehicle to the desired height. During use inspect the position

of the jack in relation to the ground and the ram in relationship to the load. If conditions look to be

unstable slowly lower the load completely to make appropriate changes.

When the vehicle or load is lifted to its desired height place safety stands (jack stands) in their

designated locations and adjust the stands support columns as close to the designated vehicle

support points as possible. Although jack stands are individually rated they are not to be used in a

matched pair to support one end of the vehicle only. Rotate the air lever to the left to lower the vehicle

onto the safety stands. After the work is done rotate the air lever to the right until the vehicle or load

is high enough to remove the safety stands.

WARNING:

Ensure that you read and understand all safety

instructions and warnings before use.
