connecting nailer with compressor. 

 

Do not connect this tool to a system with maximum potential. Only disconnect the 
quick connector with the body tai l portion of the air inlet. 
No compressed air can be guaranteed when disconnecting. 
 
Disconnect tool from air supply before performing maintenance, clearing a jammed 
fastener, leaving work area, moving tool to another location, or handing the tool to 
another person. 
 

PREPARING THE TOOL BEFORE DRIVING 

1. After reading and understanding this entire manual, connect tool to air supply. 

CAUTION: 

Keep tool pointed away from yourself and others at all times. 

 
Always connect tool to air supply before loading fasteners. 
 
Do not load fasteners with trigger or safety depressed. 
 
Always wear Z87 approved safety glasses, and hearing protection when preparing or 
operating the tool. 
 
Never use a tool that leaks air or needs repair. 
 
2. Depress handle (See A Fig. 14) and open latch. 
 
3. Rotate adjusting nut to adjust the lower housing (see B Fig. 15) according to 
desired nail length. The highest position is used for 2" , the center position used for

4. Rotate to the side of the body. Place a coil of nails over the Lower Nail Housing. 
Uncoil enough nails to reach the Feed Hook and place the second nail between the 
teeth on the Feed Hook. 
 
5. Close the latch (see Fig. 17). 
 
6. Adjust directional exhaust deflector (see Fig. 18) , so that the exhaust air blast will 
be directed away from the operator. Grasp the deflector and rotate it to the desired 
position for the current application. 

 

USING THE TOOL 

Complete all steps of PREPARING THE TOOL before using the tool. 
This tool can be fired in two different ways: 
This tool can be fired using either trigger fire (single sequential) or bump fire or 
(contact actuation). 

Trigger firing (single sequential): Turn the rotating shaft so the tail of the 
rotating shaft is up (see fig. 18A). 
 
 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
When safety bracket is pressed against the work splace, push the trigger 
repeatedly, and the nails can be shot continuously. 
Dual-action (bump fire): Turn the rotating shaft so the tail of rotating shaft is 
down (see Fig. 19A). 
 
1. Trigger firing: Put the nose on the working surface, lightly push the tool 
toward the working surface until the safety bracket is depressed, then, depress 
the trigger to drive the fasteners. This “trigger fire” method provides the most 
accurate fastener placement. In this method, the safety bracket can be adjust 
downwards with knob to avoid striking two nails at one time.
