Important Operating Instructions

controls the air supply even if the air hose is ruptured. The shut-off 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. The air hose must be long enough to reach the work area with enough extra

length to allow free movement while working.

3. 

Release the tool’s trigger.

4. 

Close the in-line shut-off valve between the compressor and the tool.

5. 

Turn on the air compressor according to the manufacturer’s directions and allow it to

build up pressure until it cycles off.

6. 

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.

7. 

Inspect the air connections for leaks. Repair any leaks found.

8. 

 If the tool will not be used at this time, turn off and detach the air supply, safely

discharge any residual air pressure, and release the trigger to prevent accidental

operation.

Note: 

Residual air pressure should not be present after the tool is disconnected from the

air supply. However, it is a good safety measure to attempt to discharge the tool in a safe

fashion after disconnecting to ensure that the tool is disconnected and not powered.
