SETUP
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" (see Figure 43) 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.
IMPORTANT: To ensure best results while cutting, make
sure the blade is tracking and tensioned correctly before
performing this procedure.

To adjust support bearing, do these steps:
1. DISCONNECT MACHINE FROM POWER!
2. Loosen support bearing adjustment cap screw (see
Figure 44).
3. Position support bearing approximately 0.016" away
from back of blade, as illustrated in Figure 45.
Note: The main purpose of this adjustment 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.
4. Tighten adjustment cap screw to lock support
bearing in place.
