Sliding Table Parallel Adjustment - Grizzly G0493 Owner's Manual

sliding table parallel
adjustment
the table is calibrated at the factory, but can
be adjusted if it changes during the life of the
machine.
Besides the tools included with the saw, this
procedure requires a felt tip pen, an adjustable
square and a set of feeler gauges, or a dial indica-
tor. note: Using a dial indicator will provide much
more accurate results.
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 maximum
height.
3.
Mark the edge of the blade with a felt tip pen.
this will allow you to take your measurements
from the exact same place on the blade.
4. using an adjustable square or a dial indica-
tor, measure the distance (a) between the
miter slot and the front of the blade, as shown
in figure 99.

6.
Measure the difference between the two
positions (use the feeler gauge if using the
adjustable square). Make note of the differ-
ence between the two measurements on a
piece of paper.
— if the gap is the same on both sides, then
the sliding table is already parallel with the
main blade.
— if the difference was less than 0.004", then
the blade parallelism is correct.
— if the difference was greater than 0.004",
then the trunnion assembly below the table
needs to be adjusted. Continue with the
next step.
7.
loosen the sliding table mounting bolts. if you
need help locating the sliding table mounting
bolts, review assembly & setup on page
21.
8.
slowly make the adjustments to the parallel-
ism adjustment bolt (see figure 100) on the
end that is closer to the blade.

9. repeat steps 4-8 until the gap between the
blade and the sliding table is equal.
10. tighten the jam nuts on the parallel adjust-
ment bolts to secure them in place
11. tighten the table mounting bolts and replace
the access plates.
