g Inaccurate
squareness between
fence (A) and fence
(B) and turn table and
base causes the
workpiece to tilt at an
angle and prevent
accurate cutting.
h Loose fitting of
swiveling portion of
hinge 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 Excessive cutting force
(pressure) is required
because of dull saw
blade.
j Excessively fast
cutting speed causes
deflection of saw
blade and inaccurate
cutting.

• Ensure that slide pipe (A) slides
smoothly with slide load of 2 to
3 kgf (4.4 to 6.6 lbs.) without
looseness.
• Replace Fence (A) [47A] and
Fence (B) [21A] as necessary.
• Check the fitting surfaces of the
Hinge Ass'y [51], Gear Case
[140] and Hinge Shaft [153] for
any foreign substance (such as
cutting dust) and remove it as
necessary.
• Reduce cutting speed.
Appropriately 10 secs. for a
square wood workpiece of 90
mm (3-17/32").
• Sharpen the saw blade again.
• Correct bend, flex or other
deformation by planing and try
cutting.
