CHECKING SLIDING MITER TABLE ASSEMBLY
To Check Miter Base Parallelism:
WARNING:
Begin by unplugging your saw. Failure to unplug saw
could result in accidental starting causing possible serious
injury.
Set saw up as if you were preparing to make a cut.
Tighten rail clamps, miter locking clamps, adjusting clamp,
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 51.
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 (F).
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.
Remove framing square and slide miter table to the rear
of miter base as far as it will go.
See Figure 52.
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
table at the rear.
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.
