Framing & Brad Nailer
To replace a piston for your framing or
brad nailer:
1.
DISCONNECT NAILER FROM THE
AIR SUPPLY!
2.
Remove all nails from the magazine
cartridge, and clean the exterior of the
nailer.
3.
Remove the four cap screws on the
back of the nailer, 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.
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 nailer until you
can grip the piston head and remove
it from the cylinder. Clean and inspect
the parts for cracks, wear, or burrs.
Always disconnect air from nailer
whenever servicing! During mainte-
nance, a nailer connected to air may
fire accidentally, causing serious per-
sonal injury!
