6.2.3 Mounting function
1) Clamp the rim on the table and mount the rise bead as described in the Instruction
manual of the tyre changer.
The positioning and the removal of the operating arm of the tyre changer from
the edge of the rim can be carried on only after having brought arms outwards
in non-working position.
2) Position the bead pressing device (Fig. 15) near the mount/demount tool (at about
3-4 cm. Lower it until the bead is level with the centre well.
Bringing the bead-pressing tool against the tyre creates a danger: the operator's
hands could be crushed between the tool and the rim. Be careful and keep your
hands far from the rim.
3) As the turntable turns the bead pressing
tool will revolve with the tyre and keep the
bead in the well. The second bead will thus
be mounted on the rim without any effort nor
danger to the operator or without risking to
damage the tyre (Fig. 15).
4) A fter fitting has been completed by means
of the control lever
pressing tool and bring the arm (10, Fig. 8)
in non-working position.
