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 filter

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-

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.

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

to reach the work area with enough

extra length to allow free movement

while working.
Make sure the tool’s trigger is in the

off position; refer to Operation section

for description of controls.
Close the in-line safety valve be-

tween the compressor and the tool.
Turn on the air compressor according

to the manufacturer’s directions and

allow it to build up pressure until it

cycles off.
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,

while checking the air output gauge

to set the right pressure range.
Inspect the air connections for leaks.

Repair any leaks found.
If the tool will not be used at this

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.
