TO CHECK MITER BASE PARALLELISM
See Figures 24 - 25.
n Unplug the saw.
n Set saw up as if you were preparing to make a cut.
Tighten rail clamps, miter locking clamps, adjusting
clamp, etc.
n 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 24.
NOTE: Front of miter base is on infeed side of saw.
n 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.
n Place a framing square (G) against the blade and
align with reference mark on miter table. Measure the
distance between the blade and the edge of miter
table.
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.
n Remove framing square and slide miter table to the
rear of miter base as far as it will go.
n 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.
n 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 table at the rear.
n Compare whether the front and rear measurements are
the same. If they are the same, proceed with checking
the miter fence alignment. If not, this indicates the
miter base needs aligning. Miter base must then be
adjusted before checking miter fence alignment. See
To Adjust The Miter Base section that follows.
