1. Remove coolant valve assembly from blade
guide.
2. Loosen set screws shown in Figure 83 to
allow guide bearings on front blade guide arm
to turn.
3. Turn hex nut on each eccentric shaft. Adjust
guide bearings (see
Figure 83) so they lightly
contact blade or have 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. Tighten set screws.
5. Adjust carbide blade guides (see Figure 83)
so they make same contact with blade as
guide bearings.
6. Adjust blade guide bearings on right blade
guide assembly in same manner, then re-
install blade guards.

1. Make sure blade is tensioned and tracking
correctly (refer to
Page 27).
2. Raise headstock high enough to give you
room to work around bearings.
3. DISCONNECT MACHINE FROM POWER!
4. Remove blade guard from blade arm.
5. Verify that back of blade lightly contacts sup-
port bearing.
— If it does not, loosen cap screws on blade
guide arm, (see
Figure 82), adjust upper
set screw (see
Figure 83), and move
assembly up or down until support bearing
lightly touches back of blade, then tighten
cap screws.
Note: If it is difficult to slide blade guide
assembly onto blade, adjust roller bearings
and carbide guides away from blade (refer
to next sub-section). Also, clean blade guide
assembly of any shipping protectant (refer to
Cleanup section on Page 15).
