4.1.1 Use the bead presser as a demounting
help device.
A. In order to make the locking of hard or lowered tires
easier, the operator can use the rim pusher provided with
the bead pusher. Apply the rim pusher (Item 1, Fig.4.1.1-
1) on the bead pusher tool (Item 2), position it at the centre
of the rim (Fig.4.1.1-1) and low the rim as far as the clamps
can lock the rim (Fig.4.1.1-2).

B. Position the roller approx. 2 cm (3/4") from the rim
edge. Press down the sidewall of the tyre to ease the
introduction of the tyre bar (Fig. 4.1.1-3). Move the roller
to rest position.
To facilitate the lift of the bead on the head tool, position
the lower disk next to the edge of the lower rim edge,
hold firmly the arm of the disk and start the lifting of the
device (Fig.4.1.1-4).
Demount the first bead as described in the tyre changer
operator's manual.

C. Position the lower disk next to the lower rim edge. Hold
firmly the handle, and at the same time rotate the turntable
(Fig. 4.1.1-5). This operation allows loosening the bead if
this is stuck and helps lifting the tyre.
NOTE: A certain effort on the handle of the lower disk
in radial direction is normal to counter-
balance the action of the turntable that
pushes the disk off the center when rotating.
THE LOWER DISK DEVICE CANNOT BE LOCKED
BECAUSE OF SAFETY REASONS.
