ADJUSTMENTS
POSITIVE STOP ADJUSTMENTS
See Figure 43.
NOTE: These adjustments were made at the factory and
normally do not require readjustment.
 Unplug the saw.
If the cutting wheel is not perfectly vertical (0°):
 Loosen the bevel lock knob.
 Place a combination square beside the wheel.
 Using a wrench, turn the 0° hex bolt until the wheel is
square to the table and the hex bolt is resting on the saw
housing.
 Tighten the bevel lock knob and recheck.
If the cutting wheel is not an exact 45°:
 Loosen the bevel lock knob.
 Move the saw arm to a 45° angle.
 Place a combination square beside the wheel and set the
saw arm at 45°.
 Using a wrench, turn the 45° hex bolt until the hex bolt
is resting on the saw housing.
 Tighten the bevel lock knob and recheck.
After squaring adjustments have been made, it may be
necessary to loosen the bevel scale and reset it to zero.
ANGLE ADJUSTMENT OF THE LASER GUIDE
LINE
See Figure 44.
If the laser line drifts towards or away from the blade as the
head is moved up and down, the laser guide line might not be
in alignment with the wheel, make the following adjustments:
 Using a Phillips screwdriver, remove the cover screw.
 Turn the angle adjustment screw left or right as needed
to place the laser guide line and wheel on the same path.
 Move the saw arm up and down, and inspect the laser
line position. If the laser line drifts out of position as the
saw arm moves, turn the angle adjustment screw until
the laser no longer moves.
 Reinstall the cover screw.
