8-3-1. Adjustment of Saw Blade parallel to Miter Gauge Groove
This is probably the most difficult of the adjustments. Before shipment from the factory this adjustment was made
but it should be rechecked and readjusted if necessary.
CAUTION: The adjustment must be correct. Kickback could result and accurate cuts cannot be made.

(1) Loosen the saw blade tilt lock handle by turning it
counterclockwise. Move the saw blade tilting mechanism to
the left and set the saw blade to 0 with the stopper.
(2) Turn the wheel fully clockwise and set the saw blade to the
maximum cutting height (see Fig. 15-a).
(3) Select a tooth on the saw blade which is bent to the right.
(4) Mark that tooth with a pencil or permanent marker.
(5) Set the miter gauge to 90 and tighten the clamp handle (B)
to lock it in that position. Place the miter gauge in the left
hand groove in the table top (see Fig. 15-b).
(6) Rotate the saw blade to bring the marked tooth to the front
and about 12.7 mm (1/2") above the table top.
(7) Place a bar or square flat against the miter gauge.
(8) Move the bar or square toward the saw blade until it just
touches the tip of the marked saw blade tooth.
(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. 15-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.
