Adjusting Roller Bearings
Guide roller bearings should only be adjusted
after the carbide blade guides (see
Adjusting
Carbide Blade Guides on Page 66).
To adjust roller bearings:
1. DISCONNECT MACHINE FROM POWER!
2. On left blade guide, loosen cap screw of front
roller bearings (see
Figure 100).
3. Turn eccentric bushing clockwise to adjust
roller bearings closer to blade, and counter-
clockwise to adjust them further from blade
(see
Figure 100). Roller bearings should
lightly contact blade or have a maximum
clearance of 0.002".
Note: Since bearings twist blade into posi-
tion, it is acceptable if there is 0.001"-0.002"
gap between blade and front or back of bear-
ing. Just make sure not to squeeze blade too
tightly with bearings. After guide bearings
are set, you should be able to rotate guide
bearings (although they will be stiff) with your
fingers.
4. While holding eccentric bushing in place,
tighten cap screw to secure setting.
5. Repeat Steps 2–4 on right blade guide.
