— If the wheels are parallel and coplanar, the
straightedge will touch the top and bottom
rims on both wheels. No further adjustment
is required.
— If the wheels are parallel but not coplanar,
the straightedge will touch the top and bot-
tom rims on one wheel, but will not touch
either rim on the other wheel. In this case,
shim the wheel that does not touch the
straightedge, as instructed in the following
Shimming a Wheel procedure.
— If the wheels are not coplanar, the straight-
edge will touch both rims of one wheel, but
at an angle to the other wheel. In this case,
you will need to adjust the tracking of the
upper wheel.
If the upper wheel is tilted from top to
bottom only, perform the Blade Center
Tracking procedure as instructed on Page
23.
If the upper wheel is tilted from side to side,
perform Upper Wheel Lateral Adjustment
procedure on Page 51.
Shimming a Wheel
A wheel that is parallel with the other wheel, but
is not coplanar, must be shimmed by the distance
that it is not in the same plane with the other
wheel.
To shim a wheel:
1.
DISCONNECT BANDSAW FROM POWER!
2.
Adjust the upper wheel tracking so that it is
parallel with the bottom wheel.

3. With the straightedge touching both rims of
the wheel that does not need to be adjusted,
measure the distance away from the other
wheel with a fine ruler, as shown in the figure
below. The distance measured with the ruler
is the distance this wheel must be shimmed.
Figure 63. Measuring the distance to shim the
wheel to be coplanar.
4. Remove the wheel to be shimmed, then
place shimming washers in the amount mea-
sured in Step 3 onto the wheel shaft.
5. Re-install the wheel and secure it in place.
6. Re-install the blade, then properly tension it
for operation.
Note: Often the wheels may be coplanar with
the blade loose, then be pulled out of align-
ment when it is tightened.
7. Perform the previous Checking Wheel
Alignment procedure. If necessary to make
the wheels parallel, repeat this procedure.
8.
When you are satisfied with the adjustment,
re-install the blade and close the wheel cov-
ers.
