Making Adjustments to Your Saw
To align the blade to the tilt axis, you need to adjust the position of the nut and standoff on the top bolt of the
secondary elevation shaft until the misalignment between the blade and the miter slot as measured by sliding
the dial indicator across the blade from front to back at a 0º tilt angle is 2.4 times the measurement taken at a
45º tilt angle, but in the opposite direction.
For example:
if the measurement taken at 45° was +0.006 inch,
then the misalignment at 0° should be adjusted to (-2.4) x (0.006) = -0.014 inch
To make the adjustment, use a 10 mm wrench to turn both the small nut and the standoff on the top bolt of
the secondary elevation shaft (shown in Fig. 102). Only make small turns (about one-third of a turn at a time).
To create a positive misalignment, fi rst loosen the nut and then turn the standoff counter-clockwise the same
amount so that it moves towards the nut. To make a negative misalignment, fi rst turn the standoff clockwise
and then turn the nut clockwise the same amount so that it moves towards the standoff. You will see the dial
indicator reading go positive as you create a fi nal negative misalignment and negative as you create a fi nal
positive misalignment.
Keeping the dial test indicator positioned toward the front of the saw with the measurement arm about
1
⁄
2
inch
inside the front edge of the blade, set the dial readout to zero. Slide the dial indicator mount toward the back of
the saw until the measurement arm is about
1
⁄
2
inch inside the rear edge of the blade. Note the readout.
If the readout is -2.4 times the measurement you took at 45º, the bolt should be correctly adjusted. Otherwise,
repeat the above process of adjusting the top bolt on the secondary elevation shaft until the dial indicator at 0º
tilt angle reads -2.4 times the measurement taken at 45º as the dial indicator is moved across the blade from
the front to the back.
Once the bolt is adjusted correctly, the blade should now be parallel to the tilt axis. Make sure the small nut
at the end of the bolt is tight. Since the alignment of the blade has been changed, the table must now be
realigned. Align the table as described on page
65 , using the precision alignment procedure.
Once the table has been realigned, you can check the parallelism of the blade to the tilt axis by tilting the blade
to
45º and measuring the alignment between the blade and the miter slot. If the misalignment of the blade and
the miter slot is less than 0.002 inch at both 0º and 45º, then the blade is parallel to the tilt axis. If necessary,
you can fi ne tune the alignment by repeating the above procedure.
