6.
Open the nose cover as if to clear a
jammed nail.
7.
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.
8.
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.
9.
Place a new O-ring on the new piston
and apply a thin film of the nailer
lubricating oil on the O-ring.
10.
Insert the new piston in the cylinder.
Make sure that the grooves on the
piston shaft line up with those on the
guide at the bottom of 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, double-check
the alignment of the piston shaft with
the grooves on the guide.
11.
After the piston is inserted correctly,
close the magazine. Replace the rear
cap assembly and tighten the four
cap screws.
12.
For more assistance, or to install a
complete O-ring set, refer to the
appropriate breakdown diagram in
the back of this manual for O-ring
locations.
