8. Apply a thin film of 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.
Palm Nailer
To replace a piston for your palm nail-
er:
1. DISCONNECT NAILER FROM THE
AIR SUPPLY!
2. Using a 19mm wrench, remove the
nose piece, depth guide, compression
spring, and flat washer.
3. Use the 4mm hex wrench to remove
the four cap screws on the nailer cap,
then remove the cap.
4. Push the ram pin towards the inside of
the nailer—this will push the cylinder
free of the housing.
5. Grab the ram pin and pull the piston
from the cylinder.
6. Apply a thin film of tool oil on the new
O-ring and place it on the new piston.
7. Insert the new piston into 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, check the alignment of
the piston inside the cylinder.
8. After the piston is inserted correctly,
place the cylinder back in the nailer
housing. If seated correctly, the cylin-
der will snap into place.
9. Push the cylinder collar down into the
housing as far as it will go. The horizon-
tal air slots on the cylinder sides should
be visible.
10. Replace the rear cap and secure it
with the four cap screws removed in
Step 3.
11. Re-install the flat washer, compression
spring, depth guide, and nose piece
onto the front of the nailer, then use
a 19mm wrench to tighten the nose
piece.
