1.Incorporate an in-line oiler, shut-off valve, regulator with pressure gauge, and filter for best service, as shown in the diagram above. An in-line shut- off valve is an important safety device because it controls the air supply even if the air hose is rup- tured.

Note: If an automatic oiler system is not used, add a few drops of Pneumatic Tool Oil to the airline connection be- fore operation. Add a few more drops after each hour of continual use.

2.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.

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 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.Close the in-line safety valve be- tween 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 and safely discharge any residual air pressure.

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 unpowered.
