SAFETY SETUP Contact Safety Trip (Bump Fire) Mechanism Definition The contact safety trip (or bump fire) mechanism allows rapid fire. Use the Mode Switch near the Trigger to change modes. The tool should only fire if the Safety Nosepiece is pressed against the workpiece and the trigger is pulled. It should fire again if the trigger is released and pulled OR if the safety is lifted and pressed against the workpiece again. The Tool should not fire if the Safety Nosepiece is not pressed against an object. Contact safety trip / bump fire should only be enabled and used by skilled operators who are aware of the hazards and use proper, safe work practices. Contact Safety Trip (Bump Fire) Mechanism Testing Procedure TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION: Point the tool at a piece of scrap wood when testing. 1. Disconnect the tool from the air supply. 2. Load the magazine with fasteners. 3. Check that the Trigger and the Safety Nosepiece move freely, without sticking. 4. Connect the air supply to the tool and set within the Operating Air Pressure indicated on the Specification chart. 5. Test the tool by pressing the Safety Nosepiece against the workpiece without pulling the Trigger. The tool must not cycle (fire). If it cycles (fires), stop immediately and have it repaired by a qualified service technician. 6. Hold the tool away, or off of the workpiece. The Safety Nosepiece should return to its original position. Squeeze the Trigger. The tool must not cycle (fire). If it cycles (fires), stop immediately and take the tool to a qualified service technician. 7. Press the Safety Nosepiece against the workpiece and squeeze the Trigger. The tool must cycle (fire) only once. Release the trigger, slide the nailer to a fresh piece of wood, and squeeze it again. The tool must cycle (fire) again only once. With the Trigger depressed, carefully lift the tool and press it against the workpiece again in a new location. The tool must cycle (fire) again only once. If it fails to act in the manner explained in bold, have it repaired by a qualified service technician. Safety Trip Mode Switch TO PREVENT SERIOUS INJURY FROM ACCIDENTAL FIRING: • Release trigger and point tool in a safe direction before changing safety trip mode. • ONLY operate the tool with the switch fully in one of the safety trip mode positions. 1. Turn the switch to the (single nail) setting to enable Single Sequential operation. This operation is safer and should be used whenever practical. 2. Turn the switch to the (multiple nail) setting to enable contact trip / bump fire operation. This operation is more dangerous. Only a skilled operator who is aware of the hazards and uses proper, safe work practices should use contact trip / bump fire operation.
