The thrust bearings support the blade from the rear and
will rotate when the blade is pushed against them while
you are cutting, As soon as you stop cutting, the
bearings should stop rotating.
11. To be sure the thrust bearing is properly supporting the
blade, turn the thrust bearing adjustment knob so that
the bearing moves toward the blade and almost touches
it.
12. While turning the upper wheel to the right by hand,
adjust the thrust bearing until it barely touches the
blade and starts to rotate. Now move the bearing back
slightly, until it stops rotating. Tighten the thrust
bearing setscrew.
13. Adjust the lower thrust bearing the same way.

NOTE: The upper and lower blade guides support the blade
and keep it from twisting during operation. An adjustment
is necessary when blades are changed or replaced,
14. To adjust the upper blade guides loosen the setscrew
which locks the blade guide holder (see illustration).
15. Turn the blade guide adjustment knob, so that the
guides move toward the blade. Move them until the
"ledge" is about 1/32" from the deepest part of the
blade teeth. This deep part is called a "gullet". Tighten
the setscrew.
16. Adjust the lower guides the same way.

blade, but don't pinch the blade. Release the guides and
rotate the upper wheel a little bit, moving the blade

from the blade than the other. Tighten both setscrews.
18. Adjust the lower guides the same way.
19. Rotate the upper wheel a few times by hand, and check
the guides and thrust bearings. Make readjustments if
necessary.
