—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 Center Blade Tracking procedure as instructed earlier in this manual.

If the upper wheel is tilted from side to side, perform Upper Wheel Lateral Adjustment procedure that follows.

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.

-50-

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 64. 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.
