7.5 Blade guide bearings
1. Disconnect band saw from power source.
2. Loosen bolt (H, Figure 7-4) and adjust
assembly so that rear bearing (J) is slightly set
back from back edge of blade. Also, inside
bearing (K) should very lightly contact blade.
Tighten bolt (H).
3. Inside bearing (K) is fixed. Outside bearing (L)
rotates on an eccentric shaft. Loosen top nut
(L
1
) and rotate bottom nut (L
2
) to adjust
eccentric bearing to very slight distance away
from blade.

7.6 Blade tracking
Blade tracking adjustment
requires running saw with back cover open. Use
caution when making this adjustment. Failure to
comply may cause serious injury.
Blade tracking has been set by the manufacturer
and should not need immediate adjustment. If blade
tracking should ever require adjustment:
1. Confirm that blade tension is set properly. To
adjust, see sect. 7.4, Blade tension .
2. Raise bow to vertical position and open blade
cover.
While performing the
following steps, keep blade from rubbing
excessively on wheel flange. Excessive
rubbing will damage wheel and/or blade.
3. Run saw at low speed and observe blade.
Blade should run next to but not tightly against
wheel flange.
4. Loosen bolts (M, Figure 7-5) with 12mm
wrench.
5. Turn set screw (N) with 4mm hex wrench, while
observing blade tracking on wheel. Turn set
screw clockwise to track closer to wheel flange.
Turn set screw counterclockwise to track away
from wheel flange.
NOTE: This adjustment is sensitive; start with
1/4 turns on the set screw and allow blade to
respond to changes.
6. Once tracking is set, tighten bolts (M).
