Setup

1. See Figure 1. Loosen and remove the four screws holding the upper 

cover. Remove the upper cover. 

2. Note the handle position lever shown in Figure 2. Use the lever to 

place the handle in Position 4 (horizontal) as shown in Figure 3. 

3. Insert the bolt and washer near the bottom of the handle assembly. 

See Figure 4.

 

Note: When storing the jack for a long period of time, remove the bolt 

and washer to place the handle in Position 1.

4. Install the upper cover.

Operating Instructions

1. Verify the control lever is in the OFF position. See Figure 2.
2. Connect shop air supply to the jack. Recommended air pressure is 

7–10 BAR (100–145 psi). Install an air filter / lubricator in the shop 

air line, because water in the air line will damage the jack.

3. Move the control lever to the UP position to raise the saddle to the 

contact point. Move the control lever to OFF.

  Note: The extension may be used in the uppermost position if required 

to meet the contact point.

4. Check the placement of the jack: lift only on areas of the vehicle as 

specified by the vehicle manufacturer; center the load on the jack 

saddle; avoid jack wheel obstructions such as gravel, tools, or uneven 

expansion joints. 

5. Move the control lever to UP to finish lifting the vehicle.
6. Immediately place approved support stands under the vehicle at points 

recommended by the vehicle manufacturer. Slowly and carefully lower 

the vehicle onto the support stands by pushing the control lever to 

the DOWN position.

Bleeding air from the Jack

Air can accumulate within a hydraulic system during shipment or after 

prolonged use. This entrapped air causes the jack to respond slowly or 

feel “spongy.” To remove the air:
1. Move the control lever to DOWN, and hold it there for a few seconds.
2. Move the control lever to UP to complete a load-free lifting cycle.
3. Move the control lever to DOWN to retract the jack pistons. The 

pistons should react in a smooth motion; if not, repeat Steps 1–3.
