ponents, such as a connector and 

quick coupler, will make operation 

more efficient, but are not required.

WARNING!  TO PREVENT SERIOUS 

INJURY FROM ACCIDENTAL 

OPERATION: 

Do not install a female quick 

coupler on the tool.

  Such a coupler 

contains an air valve that will allow 

the air tool to retain pressure and 

operate accidentally after the air 

supply is disconnected.

Note: 

Air flow, and therefore tool perfor-

mance, can be hindered by under-

sized air supply components.

3.  The air hose must be long enough 

to reach the work area with enough 

extra length to allow free movement 

while working.

4.  Close the in-line safety valve be-

tween the compressor and the tool.

5.  Turn on the air compressor according 

to the manufacturer’s directions and 

allow it to build up pressure until it 

cycles off.

6.  Adjust the air compressor’s output 

regulator so that the air output is 

enough to properly power the tool, 

but the output will not exceed the 

tool’s maximum air pressure at any 

time.  Adjust the pressure gradually, 

while checking the air output gauge 

to set the right pressure range.

7.  Inspect the air connections for leaks.  

Repair any leaks found.

8.  If the tool will not be used at this time, 

turn off and detach the air supply 

and safely discharge any residual air 

pressure.

Note:

  Residual air pressure should not be 

present after the tool is disconnected 

from the air supply.  However, it is a 

good safety measure to attempt to 

discharge the tool in a safe fashion 

after disconnecting to ensure that the 

tool is disconnected and unpowered.

 

To Attach An Air Connector:

1.  Attach a 1/4” Connector (not  

 

included)  to  the Air  Plug  (83)  prior  to        

       operation.  

2.  Wrap about 3” of pipe thread seal     

 

tape (not included) onto threads of    

 

the Connector before attaching it to      

       the Air Plug.
