SQUARING THE BLADE TO THE MITER TABLE
See Figures 28 - 31.
 Unplug the saw.
 Pull the saw arm all the way down and engage the lock
pin to hold the saw arm in transport position.
 Loosen the miter lock handle approximately one-half
turn.
 Depress the miter lock plate and rotate the miter table
until the pointer on the control arm is positioned at 0°.
 Release the miter lock plate and securely tighten the miter
lock handle.
 Loosen bevel lock knob and set saw arm at 0° bevel
(blade set 90° to miter table). Tighten bevel lock knob.
 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.
 Rotate the blade by hand and check the blade-to-table
alignment at several points.
 The edge of the square and the saw blade should be
parallel as shown in figure 9.
 If the top or bottom of the saw blade angles away from
the square as shown in figures 30 and 31, adjustments
are needed.
 Loosen the lock nut securing positive stop adjustment
screw. Also loosen bevel lock knob.
 Adjust positive stop adjustment screw to bring saw blade
into alignment with the square. See Positive Stop Adjust-
ment in the Adjustment section.
 Retighten bevel lock knob. Next, retighten lock nut
securing the positive stop adjustment screw. Recheck
blade-to-table alignment.
NOTE: The above procedure can be used to check blade
squareness of the saw blade to the miter table at both 0°
and 45° angles.
The saw has two scale indicators, one on the bevel scale
and one on the miter scale. After squaring adjustments have
been made, it may be necessary to loosen the indicator
screws and reset them to zero.
