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.

Incorporate a filter, regulator with 1.
pressure gauge, oiler, in-line shutoff
valve, and quick coupler for best ser-
vice, as shown in the diagram above.
An in-line shutoff ball valve is an
important safety device because it
controls the air supply even if the
air hose is ruptured. The shutoff
valve should be a ball valve be-
cause it can be closed quickly.
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.
Attach an air hose to the compres- 2.
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 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.
The air hose must be long enough
3.
to reach the work area with enough
extra length to allow free movement
while working.
Close the in-line safety valve be-
4.
tween the compressor and the tool.
Turn on air compressor according to
5.
manufacturer’s directions and allow it
to build up pressure until it cycles off.
Adjust the air compressor’s output
6.
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.
Inspect the air connections for leaks.
7.
Repair any leaks found.
If the tool will not be used at this time,

release the Trigger, close the shut-off
valve, press the Trigger to discharge
