tighten the wing bolt on the miter guide rule. Then position
the miter guide rule so that the arrow on the scale plate on
the tool is aligned with the cutting line.
Secure the miter guide rule by stepping on the foot plate on
the miter guide rule. Move the tool gently forward along the
miter guide rule. Be especially careful to maintain proper bal-
ance and footing, or else loss of control and subsequent
injury may result.
Also, the miter guide rule position can be determined using
004833
the indicator on the miter guide rule. Adjust the indicator so
that its length is 0.5 mm (0.02") shorter than the distance (A)
between the edge of the tool base and the side of the cutter
blade. With this adjustment, the indicator will project toward
the cutter blade within 0.5 mm (0.02") of it as the edge of the
tool slides along the edge of the miter guide rule. Secure the
miter guide rule at the position where the indicator tip is
0.5 mm (0.02") away from the cutting line.
CAUTION:
Unplug the tool and re-adjust the indicator when
changing the miter angle of the miter guide rule.
