OPERATING AIR-POWERED IMPACT WRENCH

1.    Only use impact sockets that are specifically designed for use with an air-powered 

impact wrench.

2.    Connect the air-powered wrench to the air hose.

3.    Place the socket over the nut to be removed or installed, and depress the trigger 

in order to operate the wrench.

4.    To change direction push the button at the front of the handle. Direction of "R" for 

reverse and “F” for forward.

5.    The speed of the tool can be controlled by the air regulator.

6.    Verify that the air supply is clean, and that it does not exceed 90 PSI while 

operating the wrench. 

7.    Keep children away from tools and workplaces.

8.    Do not apply excessive or additional force to the wrench in order to remove a nut.

9.    Do not allow the air-powered wrench to run free for an extended period of time. 

Doing so will shorten the life of the wrench.

The tool owner and operator are responsible for assuring that the tool is kept in safe 

working order. Furthermore only service personnel trained by the manufacturer or 

distributor should repair the tool.

CAUTION:

Disconnect the air-powered impact wrench from the air supply before 

changing accessories, servicing, or performing maintenance. Replace or repair 

damaged parts or accessories before using the air-powered impact wrench. Use only 

recommended and properly rated replacement parts and accessories.

1.    Clean and inspect your tool every time you use it.

2.    Lubricate the air-powered impact wrench daily by dripping a few drops of air tool oil 

into the air inlet.

3.    Do not use worn or damaged accessories.

4.    Check the level of lubrication in the gearbox by removing the set-screw that is 

located under the tool head, and top it up if necessary.

5.    A loss of power or erratic action may be due to the following:

a) Excessive drain on the air line; moisture or restriction in the air pipe; incorrect 

size or type of hose connectors. To remedy these situations, verify the air supply 

and follow instructions. 

b) Grit or gum deposits in the air-powered impact wrench may also reduce 

performance. If the air-powered impact wrench has an air strainer (located in the 

area of the air inlet), remove the strainer and clean it. 

6.    When the air-powered impact wrench is not in use, disconnect it from the air supply, 

clean it, and store it in a safe, dry, and childproof location.
