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,
