Next, move the dial indicator measurement arm so that it is not touching the blade and tilt the blade to
approximately 45º. Make sure not to tighten the tilt handwheel against the 45º limit stop. Now reposition the
dial indicator measurement arm against the right side of the blade and about
1
⁄
4
inch directly above the arbor
fl ange. Slide the dial indicator mount toward the front of the saw until the measurement arm is about
1
⁄
2
inch
inside the front edge of the blade (see Fig. 101). Set the dial indicator readout to zero.
Slide the dial test indicator mount smoothly
toward the back of the saw until the
measurement arm is about
1
⁄
2
inch inside
the rear edge of the blade. Note the reading
of the dial indicator as the mount moves
across the blade. Write down the fi nal
number, including whether it is positive or
negative. This number is proportional to the
misalignment between the blade and the tilt
axis.
If the measurement is 0.002 inch or less,
then the blade is parallel to the tilt axis
within the margin of error for this procedure
and no further alignment is necessary. For
measurements larger than 0.002 inch, you
can adjust the angle of the blade to improve
the parallelism between the blade and the
tilt axis. The adjustment must be made at a
0º tilt angle.
To do this, move the dial test indicator away
from the blade, set the tilt angle back to 0º
and reposition the dial test indicator at the
front of the blade. When you slide the dial
indicator mount across the blade, you should
see little or no change in the indicator readout
since the table was previously aligned. Now,
slide the dial indicator toward the front of the
saw until the measurement arm is about
1
⁄
2
inch inside the rear edge of the blade. Set
the readout to zero.
The angle of the blade relative to the tilt
axis is controlled by two bolts that bolt the
secondary elevation shaft to the rear trunnion
(see in Fig. 102).
