(9) Without disturbing the bar clamped to the miter gauge,
move the miter gauge to the center of the saw blade.
(10) Rotate the marked tooth to the rear and slide the miter
gauge rearward until the clamped bar is closest to the tip of
the marked saw blade tooth (see Fig. 13-c).
(11) If the bar just touched the tooth when the gauge was in the
front position, it should just touch the tooth in the rear
position.
Likewise, if there was some clearance between the bar and
the tooth tip at the front, the same clearance should be at
the rear.
(12) If the front and rear clearance are not identical,
1 Remove the miter gauge.
2 Loosen the four 6 mm flat head screws.
3 Move the body and adjust it so that a bar placed on the
miter gauge has the same clearance between the front
and the rear of the saw blade.
4 Tighten the four 6 mm flat head screws.
The tool is equipped with positive stops for rapid and accurate
positioning of the saw blade at 90˚ and left bevel 45˚ to the
table.
Check and adjust the positive stops with the following
procedures.
(1) To adjust positive stop at 90˚
1 Turn the wheel fully clockwise and set the saw blade to the
maximum cutting height.
2 Loosen the saw blade tilt lock handle and move the saw
blade tilting mechanism to the left until it hits against the
stopper. Then tighten the saw blade tilt lock handle (see
Fig. 14-a).
3 Use a square to check that the saw blade is at precisely
90˚ (see Fig. 14-b).
4 If the saw blade is not at precisely 90˚, loosen the saw
blade tilt lock handle by turning it counterclockwise.
Loosen the M6 x 20 seal lock screw (see Fig. 13-c) a few
turns and move the saw blade tilting mechanism until the
blade is 90˚ to the table (see Fig. 14-b).
5 Tighten the saw blade tilt lock handle after adjustment.
6 Loosen the 5 mm machine screw and set the needle
pointer to 0˚. On completion of adjustment, recheck the
90˚ angle of the saw blade and table (see Fig. 14-c).
