Figure 3. Loading nails into magazine. 4. Slide the nails all the way down to the nose of the nailer. 5. Release the magazine pusher by pulling back on the pusher and pressing in on the catch lever. Operating If you have not read the safety instructions in this manual, do not operate the nailer. Before you operate your nailer, place five to six drops of the included oil into the quick connect fitting where the nailer connects to the air supply. To operate your nailer, do these steps: 1. Connect the air supply to the quick connect fitting. 2. To test for proper nail penetration, hold the nailer perpendicular to the surface of a piece of clean scrap wood that is thick enough for the length of nails you have loaded. -8 Model W1777 21.2" 16 Gauge Finish Nailer 3. Depress the safety nose mechanism against your workpiece. 4. Before pulling the trigger, make sure your free hand and other body parts are positioned out of the way of a potential path of a nail in case of deflection. Deflection is caused when grain irregularities, knots or foreign objects inside the wood cause the nail to change its path, resulting in the nail puncturing the surface of the workpiece, as shown in Figure 4. Adjusting Depth A depth adjustment knob is attached to the nose for setting the nail depth. To adjust the nail depth, do these steps: 1. DISCONNECT NAILER FROM THE AIR SUPPLY! 2. Rotate the adjustment knob (Figure 5) clockwise to increase nail depth, and counterclockwise to decrease nail depth. Besides damaging your workpiece, deflection can cause injury if your free hand is securing the workpiece in the location that the nail deflects. Figure 4. Example of nail deflection. 5. Pull the trigger. — If the nail drove into the wood far enough, continue with your intended operations. — If the nail either went too far or not far enough, then go to the Adjusting Depth subsection on this page. Adjustment Knob Figure 5. Depth adjustment control. 3. Connect the nailer to the air supply and test the nail depth. Repeat Steps 1–2 until the nail penetration depth is satisfactory. DO NOT place your hands near the nail point of entry. A nail can deflect and tear through the surface of the workpiece, puncturing your hand or fingers. -9 Model W1777 21.2" 16 Gauge Finish Nailer Figure 6. Nose opened to clear jam.

Remove the four cap screws on the back of the nailer, near the exhaust port. 4. Remove the cap. 5. The top of the piston should now be visible inside the cylinder, which is housed in the head of the nailer. 6. Open the nose cover as if to clear a jammed nail. 7. Watch the discharge area and push the top of the piston with your finger. You will see the piston shaft slide down the discharge area. 8. Taking care not to scratch or dent the nailer parts, use a wooden dowel or similarly shaped tool to push the piston shaft back inside the nailer until you can grip the piston head and remove it from the cylinder. Clean inspect the parts for cracks, wear, or burrs. 9. Place a new O-ring on the new piston and apply a thin film of the nailer lubricating oil on the O-ring. 10. Insert the new piston in the cylinder. Make sure that the grooves on the piston shaft line up with those on the guide at the bottom of the cylinder. The new piston should easily slide into the cylinder. DO NOT force the piston into the cylinder! If the piston is not easily inserted, double-check the alignment of the piston shaft with the grooves on the guide. 11. After the piston is inserted correctly, close the magazine.
