To Check Miter Base Parallelism

See Figures 32 - 33.

 Unplug the saw.

 Set saw up as if you were preparing to make a cut. Tighten rail clamps, miter locking clamps, lock knob, etc.

 Slide miter table (A) to the front of miter base (B) as far as it will go. Place a reference mark (C) near the end of the miter table as shown in figure 32.

Note: Front of miter base is on infeed side of saw.

 Place a reference mark on one of the blade teeth (D) and rotate the blade (E) so that the reference mark on the blade is at the front of the throat plate.

 Place a framing square (G) against the blade and align				Fig. 31
with reference mark on miter table. Measure the distance
between the blade and the edge of miter table.		e	d	c
Note: Place framing square between carbide teeth and
measure from blade. This step will insure framing square
is square against blade from the front to back of blade.				a
 Remove framing square and slide miter table to the rear
of miter base as far as it will go.
 Rotate the blade so the reference mark on the blade is
at the rear of the throat plate. Measuring from the same
mark on the blade at the rear will eliminate the effect of
blade wobble.
 Place framing square against the blade and align with
the same reference mark on the miter table. Measure the
distance between the blade and the edge of the miter		b	g
table at the rear.
 Compare whether the front and rear measurements are				Fig. 32
the same. If they are the same, proceed with checking
the miter fence alignment. If not, this indicates the miter			d	e
base needs aligning. Miter base must then be adjusted
		g
before checking miter fence alignment. See To Adjust	c			f
the Miter Table section that follows.
