Problem
Possible cause
(*: Most common cause)
Inspection method
Corrective action
1.
Nails
cannot be
driven.
• No compressed air in the
nailer
• Compressed air leak
• Fill up the nailer with
compressed air, leave the
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.
2.
Nails are
driven but
bent.
*• Worn-out piston tip
*• Broken or worn-out blade
rack
• Check the piston tip for
excessive wear.
• Check the blade rack for
break or wear.
• Replace defective
parts. See page 25.
• Nails are not completely fed
into the injection port.
• Unspecified nails are used.
• Check whether the magazine
is correctly loaded with
specified nails.
• Use specified nails.
• Remove abnormal
nails and load the
nailer with proper
nails.
• Wood material too hard to be
nailed
• Drive nails into soft wood and
check whether the driven
nails are bent.
• This nailer is not for
hard wood.
• Deformed output section
• Check the tips of the pushing
lever, blade guide, nail
support, and probe for warp,
deformation and excessive
wear.
• Replace defective
parts.
• Probe is not set at the hole of
the metal connector.
• Set the probe at the hole of
the metal connector surely
and drive nail.

3.
Nails
cannot be
driven into
the
workpiece
completely:
the lower
heads
cannot be
made flush
with the
workpiece
surface.
• Worn-out piston tip
• Check the piston tip for
excessive wear.
• Replace defective
parts. See page 25.
*• Worn-out piston rack
• Check the piston rack for
excessive wear.
• Replace defective
parts. See page 25.
• Wood material too hard to be
nailed
• Drive nails into soft wood and
check whether the nail heads
are lifted.
• This nailer is not for
hard wood.
• Weak thrusting force against
wood to be nailed
• Firmly thrust the nailer
against wood to be nailed
and start nailing. Check
whether the nail heads are
still lifted.
• Follow the nailer
operation guide.
• Deformed output section
• Check the nail guide groove
of the pushing lever, blade
guide, nail support, and
probe for any trouble (e.g.,
deformation, excessive wear,
burrs).
• Replace defective
parts.
• Insufficient grease on the
cylinder and piston section
• Check the greasing condition
of the cylinder and piston
section.
• Replenish grease.
