Remove the tire
BEFORE PROCEEDING WITH THE TIRE REMOVAL,
CHECK THAT BOTH BEADS ARE COMPLETELY
BROKEN.
5.3.1
Positioning the tool
Procedure:
• Position the tool 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 tool clears from the rim flange by
approximately 1 mm: this is necessary to avoid rim
damage (Fig. 5.1-7).
Note:
once the mount/demount tool is positioned
properly, other wheels of the same type
can be changed without having to reset
the tool.
Note:
The plastic insert inside the mount/
demount tool must be periodically
replaced. Every machine is equipped
with several plastic spare inserts (inside
the accessory box).
• Insert the bead lifting tool under the bead and
over the support of the mount/demount tool. Lift
the bead onto the mounting finger. To facilitate
this operation, press with left hand on the bead in
position diametrically opposite to that of the tool. If
desired, the bead lifting tool can be removed after
lifting the bead onto the finger (Fig. 5.1-8).
• Rotate the wheel support clockwise and at the same
time push down on the tire sidewall to move the
bead into the drop centre of the rim (Fig. 5.1-9).
• Repeat the process for removing the lower bead.
With left hand, lift the tire in a position diametrically
opposite the tool to keep it in the drop centre (Fig.
5.1-10).
• Move the swing arm aside and remove the tire.
5.3.2 Use the bead presser during
demounting
A. Position the bead presser approx. 2 cm (3/4") from
the rim edge (Fig. 5.1-11).
Press down the sidewall of the tire to ease the
introduction of the bead lifting tool.
Move the roller to rest position.
B. Demount the first bead as previously described in
the manual.
