Adjusting Blade
Guides & Bearings
The blade guide assemblies 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 blade guide assembly includes a carbide
blade guide, an eccentric bushing, and three
bearings (see Figure 77). The eccentric bushings
allow the distance between the blade and bear-
ings to be adjusted.

There is also a support bearing on the upper and
lower blade guides that is not adjustable. When
the blade guides and tracking are adjusted cor-
rectly, these bearings will make light contact with
the blade.
