NOTE:
YOUR MACHINE IS SHIPPED WITH SEVERAL
REPLACEMENT 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
PERIODICALLY REPLACED.
MAINTENANCE NOTE:
IF THE MOUNT/DEMOUNT HEAD NYLON INSERTS
ARE WEARING OUT PREMATURELY, THE CAUSE
IS MAINLY THE INCORRECT POSITIONING OF
MOUNTING HEAD ON THE RIM. THIS STRESSES
INSERTS WHICH KEEP GRANTING THE RIM
PROTECTION BUT REDUCE THEIR LIFE.
NOTE:
ONCE THE MOUNT/DEMOUNT HEAD IS POSITIONED
PROPERLY, IDENTICAL WHEELS MAY BE CHANGED
WITHOUT HAVING TO RESET THE HEAD.
NOTE:
ON VEHICLES WITH TPMS SENSORS, LOCATE THE
SENSOR AWAY FROM THE BEAD OF THE DROP
CENTER. ALSO MAKE SURE THE TIRE LEVER DOES
NOT CONTACT THE SENSOR DURING THE MOUNT
OR DEMOUNT PROCESS. DAMAGE TO THE WHEEL
AND/OR SENSOR WILL RESULT IF THE BEAD IS
BROKEN AT ANY OTHER POINT ON THE RIM.
F. Insert the mount/demount tool between the bead and the
mount/demount head. Pry the bead onto the mount/demount
head using the mount/demount head as the leverage point.
To make this operation easier, insure that the bead of the
tire, 180º 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.
It is suggested that the mount/demount tool be removed
after lifting the bead onto the mount/demount head (Fig.
4.1-6), however, you may remove the tool after the bead
has been removed.

G. Rotate the turntable clockwise and, at the same time,
push down on the tire sidewall to move the bead into the
drop center of the rim (Fig. 4.1-7).

H. Repeat the process for removing the lower bead.
This time, lift the bead opposite to the mount/demount
head to keep it in the drop center (Fig. 4.1-8).
If you meet diffi culty during this operation, use the bead
presser assist device PBA (see chapter 5.3).
Tilt the column backwards and remove the tire.
