fixing flange 5 by a lock nut wrench. Place the
new wheel on thesupport flange 3 with the in-
scriptions facing up, and screw down flange 5
facing its flat side towards the wheel, using the
lock nut wrench. Use blotters if the wheel has
been delivered with them. After replacing the
wheel operate the machine with the new wheel
in no load mode for one minute. Vibrating or
otherwise improperly rotating wheels must be
replaced immediately and discarded.
