Parts List & Operating Instructions

WARNING: Failure to heed the following warnings can result in personal injury and/or equipment

damage. These warnings cannot cover every situation, so have safety foremost in your mind when

setting up a job.

• Read, understand, and follow safety precautions and operating instructions. If the

operator cannot read these instructions, operating instructions and safety precautions

must be read and discussed in the operator's native language.

• Wear eye protection that meets the requirements of ANSI Z87.1 and OSHA.

• Inspect the jack before each use; do not use the jack if it is damaged, altered, or in

poor condition.

• To prevent tipping, set up the jack on a hard, level surface.

• The load must not exceed the rated lifting capacity of the jack. Lift only dead weight.

• Center the load on the jack saddle; off-center loads can damage the seals and cause

hydraulic failure.

• Use the jack for lifting purposes only. This jack is designed to LIFT loads, not support

loads. Immediately support a lifted load with jack stands.

• Stay clear of lifted loads.

• The safety valve is set at the factory; no further adjustment is needed.

• Use only approved hydraulic fluid, such as Chevron AW Hydraulic Oil MV or equivalent.

1. Add 1/2 oz. clean lubricating oil to the air inlet, and connect the air supply. CAUTION: To prevent damage

to the air pump, the air supply must be clean and dry.

2. Assemble the adapter holder to the handle using the U-bolts, nuts, and spring washers provided. See

Figure 1. Note: When not using the adapters, store them on the holder. Lock each adapter in place with a

hitch pin.

1. Tightly close the release valve knob (located on top of the "T" handle) by turning it clockwise.

2. Center the load on the jack saddle. Connect the air supply, and squeeze the air valve lever to raise the

load. Release the air valve lever to stop movement.

3. Transfer the load to support stands.

4. To lower the jack, open the release valve knob by SLOWLY turning it counterclockwise.

Note: To adjust the handle, pull up and then release the lever to lock it in one of three positions.

Bleeding the Jack

Air bubbles can become trapped inside the hydraulic system, reducing the efficiency of the jack. Purge air

from the system as needed by following these steps:

1. With the jack sitting on its base and the ram retracted, bleed air by opening the release valve.

2. Pump for 10 seconds.
