5.2.2 Removing the tires
BEFORE PROCEEDING WITH THE TYRE
EXTRACTION, CHECK THAT BOTH BEADS ARE
COMPLETELY BROKEN.
5.2.2.1 Head Positioning
Procedure:
•
Lift the mount/demount head completely out of the
work zone, with the control (
4 Figure 5.2.2-1
).
Note
: In the opening / closing of the operatine arm
lower the tyre shoulder with the bead breaker
disc, in order to make room for the moving
head.
• Activate the pedal control (
3 Figure 5.2.2-2
) to bring
the Swing Arm into the working position on the wheel.
DURING THE CLOSURE OF THE HEAD, MAKE SURE
THAT ITS POSITION DOES NOT KNOCK INTO THE
WHEEL.
•
Bring the tool
into contact with the edge of the rim
and lock it in place (
Figure 5.2.2-2
).
The tool automatically moves away from the rim in a
vertical and radial sense by about 2 mm; this is
necessary to prevent damage to the rim.
Note
:
once the mount/demount head is
positioned properly, matching wheels may
be changed without having to reset the
head.
Note
:
The plastic inserts inside the mounting/
demounting head must be replaced
regularly. Each machine is supplied with
various spare inserts (in the accessories
box).
5.2.2.2 Upper bead extraction
Using the Automatic Tool:
•
Once the tool has been positioner, as shown in the
previous section, use demounting tool control level
to bring it in the maximum extension position (
Figure
5.2.2-3
).
Note
:
During this phase the turntable must not
be rotated.
•
Start rotating the turntable to bring the demounting
tool in position (
Figure 5.2.2-4
).
Note:
To facilitate this operation, press with your
left hand or alternatively with the Bead
Pusher tool, on the side of the tyre,
diametrically opposite to the tool.
