THE BEADING DISC MUST EXERT
PRESSURE ON THE TYRE BEAD
BUT NEVER ON THE RIM.
WHILE THIS OPERATION IS BEING
CARRIED OUT PAY ATTENTION
NOT TO DEFORM THE TYRE SIDE.
GREASE THE BEAD BEFORE THE
ROLL RE-ENTERS.

ing the pedal (
Fig. 19 ref. 3
). Keep on rotating the
wheel until the operation is completed (see

8.
Once bead breaking on the lower part
has been terminated, move the roll to rest position
lowering the lever (
Fig. 39 ref. 1
) and pressing the
lever (
Fig. 39 ref. 2
).
12.7 Demounting the tyre
When both beads are broken, the tyre can be de-
mounted.
1. Press the pedal (
Fig. 19 ref. 3
) to rotate the wheel
clockwise until the valve stem reaches “hour 1”
position.
2. Define the tool position on the rim edge pressing
the push-button (
Fig. 40 ref. 1
). Position the tool
correctly on the rim diameter (see
Fig. 41
) through
the handle (
Fig. 40 ref. 2
). If necessary perform a
horizontal adjustment of the tool arm after unlock-
ing it trough the button (
Fig. 40 ref. 3
), placed on
the handle itself.
While this phase is being carried out, stay just next
to a zone in the tyre where bead breaking has been
effectuated.
CONTROL (FIG. 40 REF. 1) (IN
ORDER TO PREVENT THE WRONG
USE OF THE TYRE CHANGER) IS
OPERATIVE ONLY IF THE TOOL
(FIG. 40 REF. 6) IS IN COMPLETE-
LY LIFTED POSITION. OPER-
ATE LEVER (FIG. 40 REF. 7), BY
SHIFTING IT UPWARDS, IN ORDER
TO MOVE THE TOOL TO SUCH
POSITION.
3. Place the presser cone (
Fig. 40 ref. 4
) (if present)
in “4 o'clock” position from the machine-head axis
and press on the tyre operating the lever of the
control unit (
Fig. 40 ref. 5
) downwards, until the
tyre bead is placed next to the rim groove.
MOVE VERY CAREFULLY THE
TOOLS HOLDER ARM TO WORK-
ING POSITION, IN ORDER TO
AVOID POSSIBLE HANDS CRUSH-
ING.
THE TOOL UNIT IS EQUIPPED
WITH A MECHANIC AUTOMATIC
MEMORY DEVICE THAT ALLOWS
TO STORE THE TOOL WORKING
POSITION. IN THIS WAY YOU CAN
WORK ON WHEELS HAVING THE
SAME RIM WITHOUT HAVING TO
PLACE EACH TIME THE TOOL ON
THE RIM EDGE.
