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 tool.
6. 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.
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 tool 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 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 remove 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.
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 for your brad nailer
or stapler:
1. DISCONNECT NAILER/STAPLER
FROM THE AIR SUPPLY!
2. Remove all nails/staples from the mag-
azine cartridge, and clean the exterior
of the tool.
3. Remove the four cap screws on the
back of the tool, near the exhaust port.
