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.
IMPORTANT: To ensure best results while cut-
ting, make sure blade is tracking (see
Initial
Blade Tracking on Page 20) and tensioned (see
Blade Tensioning on Page 22) correctly before
performing this procedure.

Adjusting Upper Support Bearing
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.
3. Position support bearing approximately 0.016"
away from back of blade (see
Figure 25).
