Operations
5.1 Demounting tubeless tires
• Remove all wheel-weights from the rim. Remove the
valve stem or core and deflate the tire (Fig. 5.1-1).
• Break outer bead starting from opposite the valve
position. lubricate the bead and rim with a tire lube
only. Break inner bead. Do not hold the foot pedal
depressed longer than necessary since this could
damage the bead. Liberally lubricate bead and rim
(Fig. 5.1-2).
• Set the rim clamps to the proper position: retract
clamps to clamp the wheel from the inside and
expand clamps to clamp from the outside. When
clamping small wheels (14" or smaller) from the
outside, set the clamps at diameter nearly equal to
the rim diameter, before placing the wheel on the
clamps. This will avoid the risk of pinching the tire.
TO MINIMIZE THE RISK OF SCRATCHING ALLOY
RIMS, THESE SHOULD BE CLAMPED FROM THE
OUTSIDE.
• Place the wheel WITH DROP CENTER UPWARDS
(Fig. 5.1-3) on the turntable, and clamp in position.
• Position the mount/demount head in contact with
the rim edge and lock it into place: the tool
automatically moves away from the rim edge
vertically. Turn the adjustment knob until the mount/
demount head clears from the rim flange about 2
mm (1/16"): this is necessary to avoid rim damage
(Fig 5.1-4).
Note: once the mount/demount head is
positioned properly, matching wheels may
be changed without having to reset the
head.
Note: the plastic insert inside the mount/demount
tool must be periodically replaced. every
machine is equipped with several plastic
inserts (inside standard equipment box).if
desired, the plastic insert may be replaced
by a steel roller also included in the
standard equipment box. follow the
instructions included with the replacement
parts.
