Checking Heeling Adjustment or Parallelism
of Sawblade to Miter Gauge Groove
While cutting, the material must move in a straight line
parallel to the sawblade. Therefore, both the miter gauge
groove and the rip fence must be parallel to the saw-
blade.
WARNING: The blade must be parallel to the miter
gauge groove. Misaligned blades could bind on
workpiece. Workpiece could suddenly kickback.
You could be cut or hit.
If the sawblade is not parallel to the miter gauge groove,
the blade will bind at one end of the cut. This is known as
“Heeling”.
WARNING: To reduce the risk of injury from acci-
dental start, make sure switch is “OFF” and plug is
not connected to power source outlet.
To check for parallelism:
1. Raise blade to 3" depth of cut.
2. Mark an “X” on one of the teeth which is set (bent) to
the left.
3. Place the head of a combination square in the groove.
Adjust blade of square so that is just touches the tip of
the marked tooth.
4. Move square to rear, rotate blade to see if marked
tooth again touched blade of square.
5. If tooth touches square at front and rear sawblade is
parallel to miter gauge groove.
6. If tooth does not touch the same amount, the mecha-
nism underneath must be adjusted to make the blade
parallel to groove.
A. Rear trunnion must be moved toward the combina-
tion square if there is a space between marked tooth
and end of square in step 4.
B. Rear trunnion must be moved away from the square
if marked tooth pushed square out of position in the
groove.
7. Loosen all three screws that hold the rear trunnion and
all three screws that hold the front trunnion.
WARNING: When reaching under table, the saw-
blade teeth may be contacted causing injury. Wear
glove or remove blade.
NOTE: All six screws can be reached through back of
saw. Use a 9/16 inch wrench. To reach left-hand front
trunnion screw, tilt blade to 45°. After loosening
screws, reposition blade at 90°.
8. Remove the table insert and lower the blade com-
pletely. The front and rear trunnion can be accessed
for adjustments through the insert opening.
9. Using a wood block and hammer, as shown, move rear
trunnion to right or left as required to realign the blade.
If necessary, shift front trunnion in similar manner, but
do not move front trunnion unless necessary. Raise
blade and recheck the alignment with the square, then
securely retighten all six trunnion screws. Recheck
alignment. Replace insert.
