Troubleshooting the Tread
If the tread is loose and comes off, check to see
that all the wheels have very little movement
when pulled. They should roll easily but should
not be floppy. If the wheels are floppy, loosen
the two nuts and re-tighten. If the treads are
still loose, the servo mounting screws can be
loosened, the servo moved up, and the screws
re-tightened.
Should the tread come off while turning and the
wheels have been adjusted and tightened, try
swapping the two bottom wheels (front to rear
and rear to front). The plastic might be too
rounded. Also check the tread connection joints.
If the interlocking rubber tabs are not pressed
together firmly, they could snag on carpet. If
there is still a problem, the two unused wheels
with sprockets can replace the two front bottom
wheels. You will need to drill or cut the end of
the wheel so the screw will go through.
