to adjust the sliding table parallel with the
main blade:
1. disConneCt saW FroM poWer!
2. Move the blade tilt to 0˚ (blade 90˚ to table),
and raise the main blade up to the maximum
height.
3. Mark one of the blade teeth with a felt tip pen.
this will be your reference point when taking
measuring points, so you take them in the
same location each time.
4. Move the sliding table all the way back, and
measure the distance "a" in figure 137,
between the marked tooth and the edge of
the miter slot.

5. rotate the blade 180°, move the sliding table
all the way forward, and measure the dis-
tance between "B" in
figure 137.
6. note the difference between the two posi-
tions.
— if the gap is the same on both sides or the
difference is 0.004" or less, no adjustments
to the table parallelism need to be made.
— if the difference is greater than 0.004",
then the sliding table parallelism must be
adjusted. proceed to
step 7.
7. loosen the nuts on t-bolts that are used to
mount the sliding table to the base (refer to
page 26 for t-bolt locations and photos).
8. loosen the hex nut on the parallel adjust-
ment screw (see figure 138), then adjust the
screw as necessary to move the table. if you
move the adjustment screw away from the
table, then push the table against the screw
before proceeding.
9. tighten the hex nut on the parallel adjust-
ment screw to secure it in place, then tighten
the table mounting nuts. repeat
steps 4–6
as necessary until the sliding table is parallel
with the blade.
