adjustments
tO set the blade at 0° and 45°
See Figures 73 - 74.
The angle settings of your saw have been set at the factory
and, unless damaged in shipping, should not require set-
ting during assembly. After extensive use, it may need to be
checked.
 Unplug the saw.
 Raise the blade.
 Remove the blade guard.
If the blade is not perfectly vertical (0°):
 Loosen the 0º adjustment screw and the bevel lock knob.
 Place a combination square beside the blade on the left.
Lock the angle by tightening the bevel lock knob and
retighten the adjustment bolt.
nOte: Make sure that the square contacts the flat part
of the saw blade, not the blade teeth.
 Turn the bevel handle until the bevel indicator points to
zero. If the bevel handle is turned as far as possible and
doesn't indicate zero properly, you may need to adjust
the bevel indicator.
If the blade is not an exact 45°:
 Loosen the adjustment screw and the bevel lock knob.
nOte: Make sure that the square contacts the flat part of
the saw blade, not the blade teeth.
 Place a combination square beside the blade on the left.
Lock the angle by tightening the bevel lock knob and
retighten the adjustment bolt.
 Turn the bevel handle until the bottom of the blade has
moved completely to the left side of the slot. Lock the
angle by tightening the bevel lock knob.
 If the blade is not an exact 45°, loosen the adjustment
bolt and the bevel lock knob.
 Adjust the bevel indicator to 45°.
 Make a test cut.
The adjustment screws must be below the saw table surface
so the workpiece doesn't catch on uneven edges. If unable
to make this adjustment, take the product to an authorized
service center.
