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 lter 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-
ponents, such as a connector and
quick coupler, will make operation
more efcient, 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 ow, 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. Release the tool’s trigger.
5. Close the in-line safety valve be-
tween the compressor and the tool.
6. Turn on the air compressor according
to the manufacturer’s directions and
allow it to build up pressure until it
cycles off.
