3. Position support bearing approximately 0.016"
away from the back of the blade, as illustrated
in
Figure 23. This can be measured with a
feeler gauge or a dollar bill.

Adjusting Blade
Support Bearings
The support bearings are positioned behind the
blade near the blade guides and prevent the blade
from pushing backward during cutting operations.
Proper adjustment of the support bearings helps
you make accurate cuts and prevents the blade
teeth from coming in contact with the blade guides
while cutting. If this happens the blade "tooth
set" can be ruined, which will greatly reduce the
blade's ability to make good cuts.
There are support bearings on the upper and
lower blade guide assemblies. Both adjust in the
same manner. The following instructions refer to
the upper support bearings. To access the lower
support bearing, you must open the lower wheel
cover (see
Page 3 for reference).
Important: To ensure best results while cutting,
make sure the blade is tracking and tensioned
correctly before performing this procedure.
Tip:
To quickly measure this setting, fold
a crisp dollar bill in half twice (when folded
tightly, four thicknesses of a dollar bill is
approximately 0.016"). Place the folded dol-
lar bill between the support bearing and the
blade, as shown in
Figure 24.
4. Tighten adjustment cap screw to lock support
bearing in place.
Note: When securing adjustment of lower
support bearing, make sure it is parallel to
blade.
