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.
