Use the Correct Type of Nails
This nailer uses only “clipped-head” nails, which are collated at an angle of 28°. “Round
Head” nails, collated at 22°, are not to be used in this tool, as they will not feed reliably, and
may cause premature wear of the driver assembly.
Harbor Freight tools offers a variety of compatible fasteners, which are usually collated in
strips of 25. Nails from other manufacturers are also widely available from home centers and
building supply stores. Please note that some manufacturers offer fasteners packaged for
their brand of air nailers, and their nail strips may be longer than the loading slot in this tool.
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 (56) of nails.
3. The Nailer should not fire if the Safety (28) is not depressed against the workpiece.
4. Make sure the Trigger (31) and Safety (28) move freely, without sticking.
5. Connect the air supply to the tool at the Air Plug (41). Set the regulator at the recom-
mended 60 to 125 PSI.
6. Test the tool by depressing the Safety (28) against the workpiece without pulling the
Trigger (31). The Tool must not cycle (fire). If it cycles (fires), stop immediately and
have it repaired by a qualified service technician.
7. Hold the tool away or off of the workpiece. The Safety (28) of the tool should return to
its original position. Point the nailer in a safe direction, towards the scrap wood and
squeeze the Trigger (31). The tool should not cycle (fire). If the tool fires, stop imme-
diately and have it repaired by a qualified service technician.
8. Depress the Safety (28) against the workpiece and squeeze the Trigger (31). The tool
must cycle (fire) only once. 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 perform in the manner
explained in bold, have it repaired by a qualified service technician.
