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 a
similar manner. The following instructions refer
to the upper support bearings.
IMPORTANT:
To ensure best results while cutting,
make sure the blade is tracking and tensioned
correctly before performing this procedure (see
Tensioning Blade on Page 27).

is to prevent the blade from being pushed
backward far enough that the blade guides
will contact (and ruin) the "tooth set" of the
blade during cutting operations.
