3 IN 1 AIR FRAMING NAILER START-UP GUIDE

WARNING

To prevent serious injury:

1. Even though the Nailer should be empty during the following procedure, ALWAYS point the Nailer at a piece of scrap wood when testing.

2. Make sure Trigger and Safety Nosepiece move freely, without sticking. Do not use nailer if Trigger or Safety sticks.

3. Disconnect the Nailer from the air compressor whenever loading or servicing.

4. WEAR ANSI-APPROVED IMPACT SAFETY GOGGLES WHEN RELOADING OR DOING ANY OTHER MAINTENANCE ON NAILER. Other people in work area must also wear ANSI-approved safety goggles.

Testing The Safety Mechanism

1. Completely empty the Magazine.

2. The Nailer should not fire if Safety Nosepiece is not depressed against scrap wood.

3. Connect air supply to the Air Coupler. Set the regulator at the recommended 70 to 120 PSI.

4. Test by depressing Safety Nosepiece against a piece of scrap wood without pulling the Trigger. The Nailer must not fire. If it fires, stop immediately and have the Nailer repaired by a qualified service technician.

5. Hold tool away or off of scrap wood. The Safety Nosepiece should return to its original position. Squeeze the Trigger. The Nailer must not fire. If the tool fires, stop immediately and have it repaired by a qualified service technician.

6. Depress Safety Nosepiece against workpiece and squeeze Trigger. The Nailer must fire only once. Release the Trigger and squeeze it again. The Nailer must not fire. With the Trigger held, carefully lift the Nailer and press it against the workpiece again. The Nailer must not fire. If it fails to perform in the manner explained in bold, have the Nailer repaired by a qualified service technician.

Loading Nails

The driving depth of a nail can be adjusted in two ways. First, by increasing or decreasing air pressure (never to exceed the maximum of 120 PSI). Second, by loosening the Depth Screw and adjusting the Bracket as shown below. Experiment on a scrap piece of material to determine how far to adjust the unit.

Put on ANSI-approved goggles and attach air supply to the Air Coupler.

Cover

Start your air compressor and set between 70-120 PSI. To fire, place the Safety Nosepiece of the Nailer on the workpiece. The Nailer should not fire if the Safety Nosepiece is not depressed. Once depressed, quickly squeeze the Trigger once. Do not fire repeatedly; nails could bounce off of one another causing injury. We recommend practicing with a piece of scrap material.

The Rubber Cover provides a non-marring surface. If desired, the Rubber Cover may be removed to expose the teeth on Safety Nosepiece. Doing so provides a nonslip surface and can improve accuracy.

When finished, disconnect the Nailer from the air source.
