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.

8.Apply a thin film of pneumatic tool oil on the new O-ring and place it on the new piston.

9.Insert the new piston in the cylinder. Make sure that the grooves on the pis- ton shaft line up with those on the guide at the bottom of the cylinder. The new piston should easily slide into the cyl- inder. 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.

10.After the piston is inserted correctly, close the magazine. Replace the rear cap assembly and secure it with the four cap screws removed in Step 3.

Note: For more assistance, or to install a complete O-ring set, refer to the appropriate breakdown diagram in the back of this manual for component locations.
