To Shim a Wheel:
1.Adjust the tracking knob so that the top wheel is parallel with the bottom wheel. With the straightedge touching both points of the wheel that does not need to be adjusted (Figure 45), measure the distance away from the incorrect wheel with a fine ruler. The distance you mea- sured with the ruler is the distance the wheel must be corrected.
Figure 45. Measuring wheel difference.
2.Remove the blade from the saw, then remove the securing nut and the washers from the wheel that needs to be shimmed. Take the wheel off.
3.Electrical washers work well for shimming because they are offered in a wide range of thicknesses. Measure how many you will need and place them on the mounting shaft.
4.Replace the wheel, any remaining washers, and the securing nut. Install and tension the blade, as it will be used during operation before you check the wheels. Often the wheels may be coplanar with the blade loose, then be pulled out of alignment when it is tightened.
5.The first time you get the wheels coplanar, place a mark on each wheel where you held the straightedge. This assures repeated accuracy every time you adjust your wheels.
When wheels are properly coplanar, the blade may not be centered on the crown of the wheel, but it will be balanced.
