Wheel Alignment - Grizzly G7211 Instruction Manual

Wheel Alignment

For proper operation of the bandsaw it is impor-
tant that the upper and lower wheels be aligned
so they are in the same plane. See Figure 5 to
understand the relationship between the wheels.
Figure 5. Wheel alignment conditions.
On the G7211/7212 it is not possible to lay a
straightedge across the two wheels to check
coplanarity and parallelism because of the
arrangement of the wheels in the cabinet. The
wheel relationship can be checked by clamping
two blocks of exactly the same size (must be at
least 2" high to extend beyond the cabinet) and
squareness to each wheel (use the large holes in
the wheels for the clamp), then use a straightedge
to check the wheel position. It will be necessary to
remove the fence and the table to perform this
check.

The adjustment knobs on the upper wheel (See
Figure 6) can be used to correct for deviation in
parallelism between the two wheels. Although this
has been set at the factory, it is a good idea to
check it occasionally to assure proper operation
of your bandsaw. Loosen the check nuts and
adjust as necessary by turning one knob in and
the other knob about the same amount. Adjust in
small increments and check the measurement
between the wheels until the wheels are in align-
ment.
Adjusting Knobs
Figure 6. Wheel alignment adjusting knobs.
If the wheels are not coplanar, the bearing mount
on the lower wheel can be adjusted to move the
wheel position in or out, or the wheel can be
shimmed on its shaft. This is a major service pro-
cedure, however, and should be undertaken very
carefully. Normally the positioning of the wheels
will not change as long as the saw is properly
cared for and is not dropped or tipped onto its
back or side. Contact Customer Service for more
information on wheel alignment if you are experi-
encing difficulty.
