12.3 TUBED WHEELS

BEAD BREAKING
WARNING: Unscrew the bush which fixes the valve when deflating the tyre so that the valve, coming in the inside of the rim, is not
an obstacle during bead breaking.
Follow all the steps described previously for bead breaking tubeless tyres.
With tubed tyres, however, stop disk movement as soon as the bead has loosened to avoid damaging the tube inflation valve.
DEMOUNTING
1) Take the mobile control unit to work position C.
2) Tip the tool carrier arm (14, Fig. D) to its non-working position.
Move it to the outside plane of the wheel and rehook it in this position.
3) Rotate the wheel and at the same time move the hook tool (18, Fig. D) forward
inserting it between rim and bead until it is anchored to the tool.
4) Move the rim 4-5 cm from the tool taking care that it does not unhook from
the bead.
5) Move the hook tool towards the outside until the red reference dot is by the
outside edge of the rim.
6) Take the mobile control unit to work position B.
7) Insert lever LA (see Fig. P) between rim and bead at the right of the tool.

8) Press down on the lever and lower the wheel to bring the edge of the rim about
5 mm from the hooked tool.
9) Turn the wheel anticlockwise pressing down on lever LA until the bead is com-
pletely off.
10) Move the tool carrier arm to its non-working position.
Lower the spindle until the tyre is pressed down against the platform .
As the platform is moved slightly towards the outside, the tyre will open a little and
thus create enough space to remove the inner tube.
11) Remove the inner tube and lift the wheel back up.
12) Take the mobile control unit to work position D.
13) Move the tool carrier arm to the inside plane of the tyre, turn the hook tool
180° and lower the arm to its work position.
Insert it between rim and bead and move it until the bead is by the from edge of
the rim (best to do this with the wheel turning).
Q
14) Move the rim about 4-5 cm from the tool making sure the hook does not detach
from the rim.
15) Portarsi con la colonnetta mobile in posizione di lavoro B.
16) Move the hook tool so that its red reference dot is about 3 cm inside the rim.
17) Insert lever LA between rim and bead at the right of the tool (See Fig. Q).
