Testing the Full 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. Make sure the tool is disconnected from the power supply.
2. Completely empty the magazine of nails.
3. The Nailer should not fire if the nose is not depressed against the workpiece.
4. Check that the Trigger (29) and the Safety (56) move freely, without sticking - see Figure
1 , next page.
5. Connect the air supply to the tool at the Air Inlet (38) set at the recommended 55-95 PSI,
and not to go over the maximum 95 PSI.
6. Test the tool by depressing the Safety (56) against the workpiece without pulling the
Trigger (29). The tool must not cycle (fire). If it cycles (fires), stop immediately and
take the tool to an authorized service technician.
7. Hold the tool away or off of the workpiece. The Safety (56) of the tool should return to its
original position. Squeeze the Trigger (29). The tool should not cycle (fire). If it cycles
(fires), stop immediately and take the tool to an authorized service technician.
8. Depress the Safety (56) against the workpiece and squeeze the Trigger (29). The tool
must cycle (fire) once only. Release the trigger and squeeze it again. The tool must
not cycle (fire). 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 described
in bold, have it repaired by a qualified service technician.

Operation
For best service, you should incorporate an oiler, regulator, and inline filter, as shown in
the diagram below. Hoses, couplers, oilers, regulators, and filters are all available at Harbor
Freight Tools.
Note: To connect this tool, we recommend a quick coupler/adapter (not included). Coupler/

drops of pneumatic tool oil in the Air Inlet (38) before each use.
