Aligning Wheels
Wheel alignment is important for optimal perfor-
mance from your bandsaw. Wheels are properly
aligned when they are parallel with each other and
in the same plane or “coplanar” (see the illustra-
tion in the figure to the right).
When wheels are coplanar, the bandsaw is
more likely to cut straight without wandering; and
vibration, heat, and blade wear are considerably
decreased because the blade is automatically bal-
anced on the wheel.
Bringing the wheels into alignment may require a
combination of shimming a wheel and adjusting
the position of the lower wheel shaft.

or
Wheels parallel and
aligned: No adjust-
ment needed.
Wheels parallel, but
upper or lower wheel
is not coplanar with the
other wheel: Move the
upper wheel in or out.
Upper wheel is not
vertically aligned with
lower wheel: Use
blade tracking knob
to tilt upper wheel.
Lower wheel is not
laterally aligned with
upper wheel: Adjust
rear adjustment set
bolts to tilt lower wheel
left/right.
4. Check wheel alignment, and adjust tracking
knob to bring both wheels into alignment as
much as possible. If wheels cannot be adjust-
ed coplanar, use
Figure 70 to determine how
to proceed with alignment adjustments.
To check wheel alignment:
1. DISCONNECT MACHINE FROM POWER!
2. Remove table.
3. With blade on and properly tensioned, hold a
straightedge close to center of both wheels.
Make sure straightedge fully extends across
rims of both wheels, as shown in
Figure 69.
