Testing The Single Sequential Safety Trip Mechanism
Warning: Even though the nailer should be empty during this procedure, ALWAYS
point the Nailer at a piece of scrap wood when testing.
1. The Nailer should not fire if the nose is not depressed against the workpiece. This
tool has a single sequential safety trip mechanism, which is designed to prevent
inadvertent firing. The tool will only fire if the Safety (38) is resting on the workpiece
prior to pulling the Trigger (44).
2. Make sure the tool is disconnected from the air supply.
3. Empty the magazine of nails or staples.
4. Check that the Trigger (44) and the Safety (38) on the nose of the tool, move freely,
without sticking.
5. Connect the air supply to the tool at the Air Plug (79) and set at the recommended 70-
125 PSI, and not over the maximum 125 PSI.
6. Test the tool by depressing the Safety (38) on the nose of the tool against the workpiece
without pulling the Trigger (44). The tool must not cycle (fire). If it cycles (fires), stop
immediately and take the tool to a qualified service technician for repair.
7. Hold the tool away, or off of the workpiece. The Safety (38) or nose of the tool should
return to its original position. Squeeze the Trigger (44). The tool should not cycle
(fire). If it cycles (fires), stop immediately and take the tool to a qualified service
technician.
8. Depress the Safety (38) against the workpiece and squeeze the Trigger (44). The
tool must cycle (fire) once only. Release the trigger and squeeze it again. The tool
must cycle (fire) again only once. With the Trigger held, carefully lift the nailer and
press it against the workpiece again. The tool must not cycle (fire). If it fails to act in
the manner explained in bold, have it repaired by a qualified service technician.
