Air Supply

 

TO PREVENT 

EXPLOSION: 

Use only clean, dry, regulated, 

compressed air to power this 

tool.  Do not use oxygen, 

carbon dioxide, combustible 

gases, or any other bottled 

gas as a power source for this 

tool.

1.  Incorporate an in-line oiler, shut-off 

valve, regulator with pressure gauge, 

and filter for best service, as shown in 

the diagram above. 

 An in-line shut-

off valve is an important safety 

device because it controls the air 

supply even if the air hose is rup-

tured.

Note: 

If an automatic oiler system is not 

used, add a few drops of Pneumatic 

Tool Oil to the airline connection be-

fore operation.  Add a few more drops 

after each hour of continual use.

2.  Attach an air hose to the compres-

sor’s air outlet.  Connect the air hose 

to the air inlet of the tool.  Other com-
