Aligning Wheels
The following adjustment was performed at the factory
and should not need to be performed again unless there
is a wheel alignment problem, or one or more wheels are
replaced.
When wheels are coplanar (see Figure 98), the bandsaw
is more likely to cut straight without wandering; and
vibration, heat, and blade wear are considerably
decreased because the blade is automatically balanced on
the wheel.
Bringing the wheel into alignment may require a
combination of shimming a wheel and adjusting the
position of the lower wheel shaft.

Checking Wheel Alignment
1. Make "Coplanarity Gauge" shown in Figures 98–99.
Note: For best results, straighten the 2x4 with a
jointer before cutting. Alternatively, you can cut
the gauge out of a new sheet of
1
⁄2"—
3
⁄4" plywood
using a table saw. The "factory edge" of the plywood
will ensure a straight and parallel gauge.
2. DISCONNECT MACHINE FROM POWER!
3. Remove blade (refer to Changing Blade on Page 50),
remove table, then re-install and properly tension
blade (refer to Tensioning Blade on Page 30).
