Remedy

Low cutting accuracy
--- poor squareness of
cut surface
a) Because of poor
squareness between
the table and saw
blade, the saw blade
enters the material at
a slant.
b) Large run out of saw
blade
(Large vibration)
c) Poor parallelism of
table upper surface
d) Poor parallelism
between the table and
the extension wing
e) Poor parallelism
between the miter-
gauge groove and
saw blade
f) Poor parallelism
between the rip fence
and saw blade
g) A too fast cutting
speed causes the saw
blade to deflect and
results in low
accuracy.
h) Excessive force is
applied because of a
dull saw blade.
i ) Deformation of the
material such as a
curvature or bend
causes the material to
move during cutting.

• Readjust the squareness of the
saw blade using the M6 x 20
Seal Lock Screw [61].
• Replace the Saw Blade [704].
• Check Washer (A) [98] for
dents, etc. If any, remove with
a file.
• Replace Washer (A) [98].
• Replace the Table [67].
• Loosen the M8 x 20 Bolt (W/
Washers) [153], M6 x 35 Hex.
Socket Hd. Cap Bolt [73] and
readjust the parallelism
between the Table [67], and
Extension Wing (R) [71] and
Extension Wing (L) [63].
• Replace Extension Wing (R)
[71] or Extension Wing (L) [63].
• Loosen the M6 x 25 Flat Hd.
Screw [60], and readjust the
parallelism between the miter-
gauge groove and the saw
blade.
• Loosen the M6 x 16 Hex.
Socket Hd. Bolt [40], and
readjust the parallelism
between the rip fence and the
saw blade.
• Slow down the cutting speed.
(Proper speed is 7 seconds for
50 mm rectangular lumber.)
• Sharpen the Saw Blade [704].
• Replace the Saw Blade [704].
• Correct the curvature or bend
by planing the material, and cut
again.
