explOsiOn:
use only clean, dry, regulated,
compressed air to power 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.
Attach an air hose to the compres-

sor’s air outlet. Connect the air hose
to the air inlet of the tool. Other
components, such as a connector,
air hose and quick coupler, will make
operation more efficient, but are not
required.

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.
Release the tool’s trigger.
4.
Close the in-line safety valve be- 5.
tween the compressor and the tool.
Turn on the air compressor according
6.
to the manufacturer’s directions and
allow it to build up pressure until it
cycles off.
