Framing & Brad Nailer

To replace a piston for your framing or brad nailer:

1.DISCONNECT NAILER FROM THE AIR SUPPLY!

2.Remove all nails from the magazine cartridge, and clean the exterior of the nailer.

3.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.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.

7.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 and inspect the parts for cracks, wear, or burrs.
