nailer still for one day, and
then check the nailing work.
• Check the sealing surfaces,
X-rings, and O-rings inside
the cylinder, piston, chamber
cover, and chamber base for
flaws, unwanted objects, and
other failures.
• Supply compressed
air.
• Disassemble the
nailer and clean the
chamber, piston, and
their vicinity.
• Replace the sealing
parts.
• Probe is not set at the hole

• Wood material too hard to be
nailed
• Drive nails into soft wood and
check whether nails jam.
• This nailer is not for
hard wood.
• Piston slide surface trouble
(e.g., galling, break)
• Check the surfaces on which
the piston slides (blade
guides (A), (B), pushing
levers (A), (B), probe, and
nail support (B)).
• Replace defective
parts.
<Magazine section>
• Nail feeder trouble (e.g.,
deformation, burring, break)
• Check the nail feed section
for any trouble (e.g., burring,
deformation, break,
excessive wear).
• Remove burring.
• Correct the
