Adjusting Blade Guide Bearings - Grizzly G0803Z Owner's Manual

3. Position support bearing approximately 0.016"
away from the back of the blade, as illustrated
in Figure 24. This can be measured with a
feeler gauge.
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.

back of blade.
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.

Adjusting Blade
Guide Bearings
The blade guide bearings can be adjusted left-
to-right, as well as front-to-back, relative to the
blade. Properly adjusted blade guide bearings
provide side-to-side support, from just behind the
gullets to the back of the blade, to help keep the
blade straight while cutting.
There are blade guide bearings on the upper and
lower blade guide assemblies. Both adjust in the
same manner. The following instructions refer to
the upper guide bearings.
Important: Make sure the blade is tracking and
tensioned correctly before performing this proce-
dure (see Tensioning Blade on Page 21).
