6.
Adjust the tracking knob to get both wheels
parallel. if the wheels won't go parallel to
each other, then move the lower wheel at the
adjustment hub so they line up.
7.
if the wheels will go parallel but not coplanar,
then move the lower wheel at the adjustment
hub (figure 65) as necessary.
8. figure 66 shows the positions of the wheels
when coplanar. When your wheels are copla-
nar, readjust the guide blocks and rear sup-
port bearings, and replace the wheel covers.
Note: The blade may track slightly OFF center
when the wheels are coplanar. This is natural
because the blade will be balanced ON the crown
of the tire, rather than just in the center of the tire.
This will be more noticeable with larger blades.
