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 tire to ease the introduction
of the tire 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 fi rmly the arm of the disk and start the lifting of the
device (Fig.4.1.1-4).
Demount the fi rst bead as described in the tire changer
operator's manual.
C. Position the lower disk next to the lower rim edge. Hold
fi rmly 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 tire.
