Inspection, repair or adjustment
1 • Adjust the clearance between
the Bushing [115] and slide
pipe (A) with the Seal Lock
Hex. Socket Set Screw M6 x
10 [118]. Ensure that slide pipe
section slides smoothly with a
slide load of within 3 kgf.
(g) Inaccurate
squareness between
fences (A) and (B),
turn table and base
causes the workpiece
to tilt at an angle and
prevent accurate
cutting.

(height of Fence (A)
[55])
0.1/49
(height of Fence (B)

(Fig. 63)
• Replace Fence (A) [55] or
Fence (B) [47] as necessary.
(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.
- • Check the fitting surfaces of
Hinge (A) Ass’y [87], Gear
Case [198] and Hinge Shaft
(A) [92] for any foreign
substance (such as cutting
dust) and remove it as
necessary.
(i) Excessively fast cutting
speed causes
deflection of saw blade
and inaccurate cutting.
- • Reduce the cutting speed
(appropriately 6 seconds for a
square wood workpiece of 60
mm (2-3/8")).
(j) Excessive cutting force
(pressure) is required
because of dull saw
blade.
- • Sharpen the saw blade again.
(k) The workpiece moves
during cutting because
it is bent or deformed.
- • Correct bend, flex or other
deformation by planing and try
cutting.
