Adjusting Blade
Guides & Support
Bearings
The blade guide blocks can be adjusted left-
to-right, as well as front-to-back, relative to the
blade. Properly adjusting the blade guides pro-
vides side-to-side support to help keep the blade
straight while cutting.
The support bearings are positioned behind the
blade on the blade guides and prevent the blade
from deflecting backward during cutting opera-
tions. Proper adjustment of the support bearings
is an important part of making accurate cuts and
keeps the blade teeth from coming in contact with
the blade guides while cutting, which will bend the
"tooth set" of the blade teeth and ruin the cutting
effectiveness of the blade.
There are blade guides and a support bearing on
each of the upper and lower blade guide assem-
blies. Both adjust in the same manner.
IMPORTANT: Verify blade is tracking (Page 22)
and tensioned (Page 24) correctly before per-
forming this procedure.
Familiarize yourself with the blade guide controls
shown in Figure 36 on next page.
