G9744Z Metal Cutting Bandsaw
Blade Guide
Bearings
The blade tracking has been properly set at
the factory. The tracking will rarely need to be
adjusted if the bandsaw is used properly.
To adjust the blade tracking on the bandsaw:
1. Loosen or tighten the tracking set screw in
Figure 42 until the blade is tracking properly.
The blade is tracking properly when the back
of the blade is lightly touching the flange of
both wheels.

2. Remove the V-belt from the motor pulley and
spin either wheel by hand to observe how the
blade is tracking. Make sure the blade teeth
are not cutting into any part of the saw. Adjust
as needed.

The blade guide bearings are adjusted at the fac-
tory but due to shipping and storage may need
adjustment. Use
Figures 43 & 44 to guide you
through the following steps.
To adjust the blade guide bearings:
1. Before making adjustments, make sure the
blade is tensioned and tracking correctly.
2. UNPLUG THE BANDSAW!
3. Raise the bow high enough to give you room
to work, then lock in place.
4. Remove both blade guards.
5. The back of the blade (A) in Figure 43 should
make light contact with the backing bearing
(C).
—If it does not, loosen the set screw (B)
shown in Figure 43, and move the bearing
(C) up or down until it lightly touches the
back of the blade.
The blade guide roller bearings also need to be
adjusted. The front bearing is mounted on an
eccentric and can be easily adjusted to suit the
blade thickness.
To adjust the blade guide roller bearings:
1. Loosen the set screw shown in Figure 44 to
allow the eccentric bushing to turn.
