The adjustment hub allows you to move the
lower wheel in the desired direction. Turning
all the bolts clockwise in equal amounts push-
es the wheel forward. Turning all the bolts
counterclockwise brings the wheel backward,
closer to the adjustment hub. Used individu-
ally, each bolt can control the direction that
the wheel tilts.
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 (see Figure 87) as necessary.

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.
