Making Adjustments to Your Saw
This procedure requires two measurements. For the first measurement, set the tilt angle to 0° and lower the
blade below the table. Make sure to back the hand wheels off slightly to release the pressure between the
trunnion assembly and limit stops. Next, position the dial test indicator near the right side of the blade. The
indicator measurement arm should rest against the blade approximately ½ inch inside the front edge of the
blade and about ½ inch higher than the top of the arbor washer (see Fig. 53). Depending on the geometry of
your dial test indicator, it may be necessary to position the indicator below the table.
Now measure the parallelism of the blade relative to
the miter slots in the table as described above in the
section named "Aligning the Table," see page 46.
If necessary, adjust the alignment of the table so
that the blade is parallel to the miter slots when the
blade is below the table.
For the second measurement, raise the blade to the
maximum height above the table, making sure to
back the elevation hand wheel off slightly to release
the pressure between the trunnion assembly and
the upper elevation limit stop. Reposition the dial
test indicator so that the measurement arm is resting
against the blade approximately ½ inch inside the
front edge of the blade and about ½ inch higher
than the top of the arbor washer (see Fig. 46).
Measure the parallelism of the blade relative to the
miter slots in the table as described above.

If the second measurement is 0.002 inch or less,
then the blade elevation assembly is aligned within
the margin of error for this measurement and,
therefore, no further alignment is needed. If the
set screw
second measurement is greater than 0.002 inch,
you can adjust the angle of the rear shaft relative to
the front shaft to reduce the error.
The angle of the rear shaft is set by the eccentric
bushing at the bottom of the shaft (see Fig. 54). The
eccentric bushing is locked in place by a set screw
in the elevation plate, and a smaller set screw in the
side of the bushing.
To adjust the shaft angle, make sure the blade is
still about 3 inches above the table and the dial
indicator is still reading the second measurement (if
not, repeat the second measurement as described
above). Next, loosen the set screw in the elevation
plate using a 4 mm allen wrench and the smaller set
screw in the eccentric bushing using a 2.5 mm allen
wrench. You can access the set screws by opening
the belt access door on the left side of the cabinet.
