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 quick coupler on the tool. 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 Trigger.

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, while checking the air output gauge to set the right pressure range.

8.The air pressure setting must not exceed job site regulations/restrictions. The air pressure setting must not exceed 120 PSI when being used with work pieces that have a thickness of less than 1-3/4”.

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

10.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 unpowered.
