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 33.

Eccentric Bushing
Adjust the other eccentric blade guide bear-
6.
ing in the same manner. The backing bear-
ing is not adjustable and will make light
contact with the blade.
Adjust the carbide blade guides so they
7.
make the same contact with the blade as
the bearings.

Blade Guides

The blade guides should be as close to the
workpiece as possible. This will help ensure
straight cuts by keeping the blade from twisting
and drifting off the cut line.
To adjust the blade guides:
1. Loosen the knob shown in Figure 34 and
slide the rear blade guide as close to the
workpiece as possible, then tighten the
knob.
