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 shut-off valve, regula-
tor with pressure gauge, and lter
for best service, as shown in the
diagram above. An in-line shutoff
valve is an important safety device
because it controls the air supply
even if the air hose is ruptured.
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 efcient, 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.
The air hose must be long enough 3.
to reach the work area with enough
extra length to allow free movement
while working.
Make sure the tool’s trigger is in the 4.
off position; refer to Operation section
for description of controls.
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.
Adjust the air compressor’s output 7.
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. 8.
Repair any leaks found.
If the tool will not be used at this 9.
time, turn off and detach the air sup-
ply, safely discharge any residual air
pressure, and release the throttle
and/or turn the trigger to its off posi-
tion to prevent accidental operation.
