NOTE:
EVERY MACHINE IS EQUIPPED WITH SEVERAL RE-
PLACEMENT PLASTIC INSERTS (INSIDE STANDARD
EQUIPMENT PACK). THE PLASTIC INSERTS WILL
HELP AVOID DAMAGE FROM ACCIDENTAL CONTACT
BETWEEN THE MOUNT/DEMOUNT HEAD AND THE RIM.
THE PLASTIC INSERTS WILL NEED TO BE PERIODI-
CALLY REPLACED.
MAINTENANCE NOTE:
IF THE MOUNT/DEMOUNT HEAD NYLON INSERTS ARE
WEARING OUT PREMATURELY, THE CAUSE IS THE
OPERATORS FAILURE TO CORRECTLY SET THE SWING
ARM ADJUSTMENT KNOB, CAUSING THE INSERT TO
INCORRECTLY CONTACT THE RIM.
NOTE:
ONCE THE MOUNT/DEMOUNT HEAD IS POSITIONED
PROPERLY, IDENTICAL WHEELS MAY BE CHANGED
WITHOUT HAVING TO RESET THE HEAD.
F. Insert the mount/demount tool under the bead and over
the support of the mount/demount head. Lift the bead onto
the mount/demount head. To make this operation easier,
insure that the bead of the tire, directly across from the mount/
demount head, is in the drop center of the wheel. Push the
tire into the drop center with your hand or bead depressor
tool if necessary.
If desired, the mount/demount tool can be removed after
lifting the bead onto the mount/demount head (Fig.15), or
you may remove the tool after the bead has been removed.
