Safety instructions
EYE PROTECTION: Which meets ANSI specifications and provides protection against flying particles both from the FRONT and SIDE should ALWAYS be worn by the operator and others in the work area when connecting to air supply, loading, operating, or servicing this tool. Eye protection is required to guard against flying fasteners and debris, which could cause severe eye injury.
AIR SUPPLY AND CONNECTIONS
Do not use oxygen, combustible gases, or bottled gases as a power source for this tool, as the tool may explode and possibly cause injury.
Do not use supply sources that can potentially exceed 200 P.S.I.G. The tool may burst, possibly causing injury.
The connector on the tool must not hold pressure when the air supply is disconnected. If the wrong fitting is used, the tool can remain charged with air after disconnecting and will be able to drive a fastener even after the line is disconnected, possibly causing injury.
Do not pull the trigger or depress the safety arm while connected to the air, as the tool may cycle, possibly causing injury.
Always disconnect the air supply: 1. Before making adjustments; 2. When servicing the tool; 3. When clearing a jam; 4. When the tool is not in use. When moving to a different work area, eliminate accidental actuation which may cause possible injury.
WARNING:
When loading the tool: 1. Never place a hand or any other part of your body in the fastener discharge area of the tool; 2. Never point the tool at anyone; 3. Do not pull the trigger or depress the safety as actuation may occur, possibly causing injury.
The operator must not hold the trigger pulled on contact trip (bump mode) except during fastening operation, as serious injury could result if the tip accidentally contacted someone or something, causing the tool to
Always keep hands and body away from the discharge area of the tool. In contact safety (bump fire) mode, the tool may bounce from the recoil of driving a fastener, and an unwanted second fastener may be driven, possibly causing
injury.
Inspect the operation of the contact safety mechanism frequently. Do not use the tool if the safety is not working correctly, as accidental driving of a fastener may occur. Do not interfere with the proper operation of the safety arm mechanism.
Do not drive fasteners with the tool at an overly steep angle or on other fasteners, as this may cause deflection of fasteners which could cause injury.

ADJUSTING DEPTH OF DRIVE SAFETY
To assure that each nail is driven to the same depth, be sure that:
- Air pressure to the tool is consistent, and a regulator is installed and properly in line with the tool.
- The tool is always held firmly against the work piece. If nails are driven too shallow or too deep into the work piece, adjust the Safety Adjust Wheel on the Safety to the desired depth.
See Diagram for details.
TOOL MAINTENANCE AND INSPECTION
- Inspect the magazine; clean it by removing any plastic or wood chips that may have accumulated.
- Make sure the Pusher Lever operates smoothly in the magazine.
- Check that the Safety Lever operates smoothly and freely up and down.
- Lubricate moving parts daily for proper operation of the tool.
ADJUSTING AIR PRESSURE
Adjust air pressure at the recommended operating pressure of 70~120 psi (4.9~8.3 bar) according to the length of nails and the hardness of the work. Correct air pressure is the lowest pressure that will do the job. Use of pressure higher than required to drive nails to proper setting puts unnecessary stress on the tool and parts.
