 Replacing Pistons/O-Rings
If you use your nailer/stapler day in and day out, repair pistons are cheap insurance against wasted down time and
lost profits, in the event that a piston or piston shaft becomes worn out. A replacement piston and O-ring kit, you can
contact with where you buy!
To replace a piston and O-ring:
1. DISCONNECT NAILER /STAPLER FROM THE AIR SUPPLY!
2. Remove all nails/staples from the magazine.
3. Remove the four cap screws on the head of the nailer/stapler, 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/stapler.
6. O pen the nose cover as if to clear a jammed nail/staple.
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. With a long flathead screwdriver or similarly shaped tool, push the piston shaft back inside the nailer/stapler
until you can grip the piston head and remove it from the cylinder. (Be careful not to scratch the discharge area
when pushing the piston shaft with the screwdriver.)
9. Place a new O-ring on the new piston and apply a thin film of the nailer/stapler 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 pusher. Replace the rear cap assembly and tighten the
4 cap screws.
12. 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.

damage to the nailer/stapler and the air couplings.
