Cause
(g) Inaccurate
squareness between
fences (A) and (B),
turn table and base
causes the workpiece
to tilt at an angle and
prevent accurate
cutting.
(h) Loose fitting of
swiveling portion of
hinge (A) ass'y and
gear case, or sluggish
movement. As a result,
components may be
deformed because of
unstable gear case or
because the operator
must apply excessive
pressure during
operation.
(i) Excessively fast cutting
speed causes
deflection of saw blade
and inaccurate cutting.
(j) Excessive cutting force
(pressure) is required
because of dull saw
blade.
(k) The workpiece moves
during cutting because
it is bent or deformed.
