Figure 11. Folded dollar between support
bearing and blade.
The support bearings back-up the blade during
the sawing operation. The important adjustments
to make with the support bearings are centering
them laterally and adjusting the distance between
the support bearing and the back of the blade.
To center the support bearings laterally:
1. Loosen the two hex bolts that allow the
upper assembly to move side-to-side.
2. Shift the entire assembly so the blade is cen-
tered on the support bearing.
3. Tighten the two hex bolts.
Support Bearings
3. Turn the upper wheel clockwise by hand and
watch the blade ride on the wheels. If the
bottom of the blade gullets are not approxi-
mately
1 ⁄
16
" away from the edge of the
wheels then you need to adjust the tracking
handwheel on the backside of the saw.
4. Turn the tracking handwheel a few times and
note the direction that the blade shifts when
you spin it by hand.
5. Adjust the tracking handwheel until the blade
gullets ride approximately
1 ⁄
16
" away from the
edge of the wheels while you are spinning
the upper wheel by hand. Your saw is now
properly tracked.
To adjust the support bearings behind the
blade:
1. Loosen the hex bolt that secures the support
bearing shaft in place.
2. Adjust the support bearing shaft so it is
approximately .016" away from the back of
the blade. Four thicknesses of a dollar bill is
approximately the equivalent to .016". For a
quick gauge, fold a dollar bill in half twice.
3. Slip your folded dollar between the back of
the blade and the support bearing as shown
in
Figure 11. Lightly pinch the folded dollar
with the support bearing and secure the sup-
port bearing shaft in place.
4. Remove the folded dollar bill.
