Unpacking

When unpacking, make sure item is intact and undamaged. If any parts are missing or broken, call Harbor Freight Tools at 1-800-444-3353.

This air tool may be shipped with a protective plug covering the air inlet. Remove this plug before set up.

Air Supply

To prevent explosion:

Use only clean, dry, regulated, compressed air to power tool. Do not use oxygen, carbon dioxide, combustible gases, or any other bottled gas as a power source for this tool.

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 components, such as a connector, air hose 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.Release the tool’s trigger.

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.
