a Large deflection of the
saw blade (It causes
rough cut surface.)
b Each surface
parallelism of washer
(A), (B) is inaccurate
due to surface defects
such as impact marks
and scratches.
c Inaccurate
squareness between
the turn table and the
saw blade causes the
saw blade to cut at an
improper angle and
make cutting marks.
d Loose fitting of
swiveling portion of
the hinge and the gear
case or sluggish
movement.
e Cutting operation
becomes sluggish
because workpiece is
warped or bent.
f Excessive vibration

• Reduce cutting speed.
• Use a thicker and shorter
extension cord.
• Replace the saw blade.
• Use a suitable Hitachi-supplied
saw blade.
• If the saw blade has a large
number of teeth, the cutting
resistance will be increased.
When using a saw blade with a
large number of teeth, reduce
the cutting speed.
• Correct workpiece deformation
with a planer.
