Operation Manual
YOUR MACHINE IS SHIPPED WITH SEVERAL
R E P L A C E M E N T P L A S T I C I N S E R T S ( I N S I D E
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 SEN-
SOR AWAY FROM THE BEAD OF THE DROP CENTER.
ALSO MAKE SURE THE TIRE LEVER DOES NOT CONTACT
THE SENSOR DURING THE MOUNT OR DEMOUNT PRO-
CESS. 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.
4.1-5), however, you may remove the tool after the bead
has been removed.

G.
Rotate the turntable clockwise (7 RPM Pedal Position)
and, at the same time, push down on the tire sidewall to
move the bead into the drop center of the rim (Fig. 4.1-6).

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. 4.1-7).
For this operation the 14 RPM Pedal Position can be
used.
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.
