Scale Calibration

The scale next to the handwheel needs to be
calibrated after the saw blade has been calibrated
at the 90º positive stop (see previous section) and
the scale does not indicate 0º.
To calibrate the scale (refer to Figure 20):
1. Loosen the blade tilt lock knob (D) by turning
counterclockwise.
2. Push the handwheel (C) in to engage the blade
tilt mechanism; then turn clockwise all the way,
bringing the blade to the 90º position to the
table. Hold the handwheel and:
3. Lock the blade tilt lock knob (D).
If the scale does not read exactly 0º:
4. Loosen the screw (B) with an off-set cross-
point screwdriver.
5. Manually adjust the scale (A) until it points
to 0º:
6. Tighten the screw (B).

3. Push the handwheel (A) in to engage the blade
tilt mechanism and turn counterclockwise all
the way, bringing the blade to the 45º position
to the table.
4. Continue holding the handwheel with the blade
in this position. Place a combination square (E)
on the table and against the blade as shown.
If the blade is not 45º to the table:
