Fence
Squareness
0.1/height
of fence
Fig. 50
Cause
f Inaccurate squareness
between the fence
and the turn table and/
or the base causes
the workpiece to tilt at
an angle and prevent
accurate cutting.
g Loose fitting of
swiveling portion of
the hinge and the gear
case or sluggish
movement. As a
result, components
may be deformed
because of unstable
gear case or because
the operator applies
excessive pressure
during operation.
h Excessively fast
cutting speed causes
deflection of the saw
blade and inaccurate
cutting.
i Excessive cutting
force (pressure) is
required because of
dull saw blade.
j The workpiece moves
during cutting because
it is bent or deformed.

Inspection, repair or
adjustment
• Replace Fence (A) [65] or
Fence (B) [54].
• Check the fitting surfaces of the
Hinge [16], Gear Case [123]
and Shaft (C) [15] for any
foreign substances (such as
cutting dust), and remove it as
necessary.
• Reduce the cutting speed
(appropriately 10 seconds for a
60 mm square wood
workpiece).
• Sharpen the saw blade again.
• Correct bend, flex or other
deformation by planing and try
cutting.
