Replacing Pistons/O-

Rings

If you use your nailer/stapler day in and day out, repair pistons are cheap insur- ance 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, part PH7664084, may be purchased for the Model H7664.

Always disconnect air from nailer/ stapler whenever servicing! During maintenance, a nailer/stapler con- nected to air may fire accidentally, causing serious personal injury!

To replace a piston and O-ring:

1.DISCONNECT NAILER/STAPLER FROM THE AIR SUPPLY!

2.Remove all nails/staples from the mag- azine.

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/sta- pler.
