25. Take caution, as some woods contain preservatives such as copper chromium arsenate (CCA) which can be toxic. When nailing these materials extra care should be taken to avoid inhalation and minimize skin contact. WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contain chemicals known (to the State of California) to cause cancer, birth defects, or other reproductive harm.
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: If an automatic oiler is not used, for smoother operation and to extend the life-span of the tool, put 3-5 drops of pneumatic Tool Oil (93) in the attached Air Plug (82-not included) before each use.
3. Connect the air supply to the tool at the Air Plug (82-not included). Set the regulator at the recommended 70 to 125 operating PSI. Do not exceed the maximum 125 PSI. 4. Test the tool by depressing the Safety (38) against a piece of scrap wood without pulling the Trigger (60). The tool must not cycle (fire). If it cycles (fires), stop immediately and have it repaired by a qualified service technician. (See Figure B.) 5. Hold the tool away or off the workpiece.
2. Check the Nail Support (88) inside the Magazine (85). The Nail Support can be adjusted up and down to use various lengths of nails from 1-1/4” to 2-1/8”: (See Figure D.) A. 1-1/4” Long Nails (Turn Magazine Post (87) to top setting). B. Between 1-1/4” and 2-1/8” Long Nails (Use middle setting). C. 2-1/8” Long Nails (Use bottom setting).

3. To fire, place the Safety (38) of the Nailer on the workpiece. The Nailer should not fire if the Safety is not depressed. Once depressed, gently and briefly squeeze the Trigger (60) once. Do not fire repeatedly. Nails could bounce off of one another, damaging the workpiece or causing personal injury. (See Figure E.) 4. Do not press the Safety (38) against the workpiece with extra force. Allow the tool to do the work. Always allow the tool to recoil off the work surface. (See Figure E.) 5.
Anytime any maintenance or repairs are done (including clearing jams), FIRST: 1. Disconnect the Nailer from its air supply. 2. Empty the Magazine (85) completely. 3. Attempt to fire the Nailer into a piece of scrap wood to ensure that it is disconnected and is incapable of firing any Nails. CLEARING JAMS 1. Occasionally, a Nail may become jammed in the firing mechanism of the Nailer, making the tool inoperable. 2. To remove a jammed Nail, disconnect the Nailer from its air supply.
