Blade Parallelism
Your table saw will give the best results if the
miter slot is parallel to the blade. If they are not
exactly parallel, your cuts and finished work will
be lower in quality. To check and adjust blade
parallelism:
1. Using an adjustable square, measure the
distance between the miter slot and the front
of your blade as shown in Figures 41 and
42.
Figure 42. 90° blade parallelism measurement.
Figure 41. 90° blade parallelism measurement.
Figure 43. Table/trunnion assembly.
2. Note the first measurement. Rotate the
blade 180° and move the square to the rear
of the blade. You may find it helpful to mark
your blade with a felt-tip pen (as a rotation
guide) at the point where the straightedge
and blade meet.
3. Compare the measurements. If the differ-
ence in measurements is less than 0.004",
your blade and table are in acceptable align-
ment move to Step 7. If the difference is
greater, you will need to adjust the trunnion
and table.
4. To adjust blade alignment, remove the
motor, wings and the upper half of the saw
from the stand. Place it upside down on 4 x
4 blocks to allow the saw blade to rotate
freely.
5. Remove the handwheels and the sheet
metal body. To maintain the trunnion assem-
bly as one unit, place a bar clamp across the
entire trunnion assembly. The four trunnion
bolts (Figure 43) can now be loosened. This
will allow the trunnion assembly to be shifted
in order to change the alignment between
the blade and the miter slot.
6. Now measure the miter slot to the blade as
in Steps 1 and 2. Move the trunnion assem-
bly until proper alignment has been
obtained. Tighten the trunnion bolts and
remove the bar clamp.
