English Mode Selection WARNING: Always wear proper eye [ANSI Z87.1 (CAN/CSA Z94.3)] and hearing protection [ANSI S12.6 (S3.19)] when operating this tool. WARNING: Keep fingers AWAY from trigger when not driving fasteners to avoid accidental firing. NEVER carry tool with finger on trigger. In contact mode tool will fire a fastener if safety is bumped while trigger is depressed. Sequential Trip Sequential trip requires the operator to hold the trigger against the work surface before pulling the trigger. This makes accurate fastener placement easier. The sequential trip allows exact fastener placement without the possibility of driving a second fastener on recoil, as described under Contact Trip. The sequential trip tool has a positive safety advantage because it will not accidentally drive a second fastener if the tool is contacted against the work surface or anything else while the operator is holding the trigger pulled. Bump/Contact Action The common operating procedure on contact trip tools is for the operator to contact the work surface to actuate the trip mechanism while keeping the trigger pulled, thus driving a fastener each time the work is contacted. This will allow rapid fastener placement on many jobs. All pneumatic tools are subject to recoil when driving fasteners. The tool may bounce, releasing the trip, and if unintentionally allowed to recontact the work surface with the trigger still actuated (finger still holding the trigger pulled) an unwanted second fastener will be driven. TO CHANGE OPERATING MODES (FIG. 1-3) WARNING: Disconnect air line from tool and remove fasteners from magazine before making adjustments or personal injury may result. SEQUENTIAL TRIP ACTION Use sequential action for intermittent nailing where very careful and accurate placement is desired. To operate the nailer in sequential action FIG. 2 mode: 1. Rotate the trigger mode selector (B) clockwise to the sequential action position , as shown in Figure 2. 2. Fully depress nosepiece against the work surface. 3. Pull trigger. 4. Release trigger. 5. Lift nosepiece off work surface. 6. Repeat steps 2 through 4 for next application. WARNING: The contact trip needs to be depressed followed by a trigger pull for each fastener followed by a release of both the contact trip and trigger after each fastener. CONTACT TRIP ACTION Bump/contact action is intended for rapid nailing on flat, stationary surfaces. When using bump action, two methods are available: place actuation and bump actuation. Rotate the trigger mode selector (B) FIG. 3 counterclockwise to the contact action position , as shown in Figure 3. To operate the tool using the PLACE ACTUATION method: WARNING: A fastener will fire each time the trigger is depressed as long as the contact trip remains depressed. 1. Depress the contact trip against the work surface. 7
