NOTE:
This clearance will be maintained as long as the
slide locking valve remains locked. The operator
may tilt the tower back out of the way and back into
place again without needing to reposition the head
when changing a like set of wheels. The tool
clearance may change with machine use and
should be inspected often. Failure to maintain
proper clearance may result in damage to the wheel
rim or tire.
