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.
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.
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 the front of the magazine until the
catch lever locks.
