(blade set 90° to miter table). Tighten bevel lock knob.
n Place a combination square against the miter table and
the flat part of saw blade.
NOTE: Make sure that the square contacts the flat part
of the saw blade, not the blade teeth.
n Rotate the blade by hand and check the blade-to-table
alignment at several points.
n The edge of the square and the saw blade should be
parallel as shown in figure 25.
n If the top or bottom of the saw blade angles away from
the square as shown in figures 26 and 27, adjustments
are needed.
n Using a 10 mm wrench or adjustable wrench, loosen the
lock nut securing positive stop adjustment screw. Also
loosen bevel lock knob.
n Adjust positive stop adjustment screw to bring
saw blade into alignment with the square. See Figure 28.
n Retighten bevel lock knob. Next, retighten lock nut
securing the positive stop adjustment screw. Recheck
blade-to-table alignment.

squareness of the saw blade to the miter table at both 0°
and 45° angles.
