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.

3. The air hose must be long enough

to reach the work area with enough

extra length to allow free movement

while working.

4. Make sure the tool’s throttle or switch

is in the off position; refer to Opera-

tion section for description of con-

trols.

5. Close the in-line safety valve be-

tween 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 shall 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 value.

8. Inspect the air connections for leaks.

Repair any leaks found.

9. 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 compressor switch to

its off position to prevent accidental

operation.
