air hose is ruptured. The shutoff valve should be a ball valve because it can be closed quickly. See pages 8 and 9 for Air Tool Setup procedures.

Note: If an automatic oiler system is not used, add a few drops of Pneumatic Tool Oil into 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. Please note: a quick coupler will be needed for proper connection.

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 tool’s Trigger (44).

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 90 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.

Nail Penetration Depth Adjustment

1.With the tool connected to its air supply and with the nails loaded, test fire on a scrap material (similar to the workpiece) and note the depth of nail’s penetration.

2.To adjust nail depth penetration, rotate the Depth Knob (52). Turn the Depth Knob to the left (+) for deeper nail penetration and to the right (-) for more shallow penetration.

3.CAUTION! When working with asphalt shingles in particular, the nail head should not sink below the top face of the shingle.
