Blade Guide Bearings - Grizzly G9743 Owner's Manual

Blade Guide
Bearings
The blade guide bearings come adjusted from the
factory and the need for adjustment should rarely
occur. Uneven blade wear and crooked cuts
may be the result of improper adjustment. Each
bearing assembly has an eccentric bushing that
allows the distance between the blade and bear-
ings to be adjusted. The bearings are secured in
place by a hex nut and a lock washer as shown
in Figure 39.
