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 a filter, regulator with
pressure gauge, oiler, in-line shutoff
valve, and quick coupler for best
service, 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 because 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
before operation. Add a few more
drops after each hour of continual
use.
2. Attach an air hose to the
compressor’s air outlet. Connect the
air hose to the air inlet of the tool.
Other components, such as a coupler
plug 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
performance, can be hindered by
undersized 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 (13); refer
to Operation section for description of
controls.
5. Close the in-line safety valve between
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.
7. 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,
