9. Miter cutting procedures
(1) Loosen the side handle and pull up the lever
for angle stoppers. Then, adjust the turntable
until the indicator aligns with desired setting
on the miter scale (Fig. 35).
(2) Re-tighten the side handle to secure the
turntable in the desired position.
(3) The miter scale (Fig. 36) indicates both the
cutting angle on the angle scale and the
gradient on the grade scale.
(4) The gradient, which is the ratio of the height
to the base of the triangular section to be
removed, may be used for setting the miter
scale instead of the cutting angle, if desired
(see Fig. 36).
(5) Therefore, to cut a workpiece at a grade of
2/10, set the indicator to position a as indicated
in Fig. 36.
NOTE
Positive stops are provided at the right and
○
left of the 0° center setting, at 15°, 22.5°, 31.6°
and 45° settings.
Check that the miter scale and the tip of the
indicator are properly aligned.
Operation of the saw with the miter scale and
○
indicator out of alignment, or with the side
handle not properly tightened, will result in
poor cutting precision.
10. Miter angle fi ne adjustment
(1) Rotate the turntable to the miter angle you
need.
(2) When making fi ne adjustments of the miter
angle, turn the knob (A) while pulling up the
lever (Fig. 38).
NOTE
Turning knob (A) clockwise, allows fi ne adjustment of the turntable to the right. Turning
knob (A) counterclockwise, allows fi ne adjustment of the turntable to the left.
(3) After adjusting to the desired angle, tighten the side handle.
CAUTION
Always check that the side handle is secured and the turntable is clamped.
If you attempt angle cutting without clamping the turntable, then the turntable
might shift unexpectedly causing injuries.
