Ensure that the upper heel of the tyre slides in the
semi drop centre passing near the rim edge. To facili-

While operating the bead pressing device keep the
bead low in the semi drop centre of the tire and
start rotating the tightening flange (operate the lo-

If the bead does not fit correctly in the semi drop
centre, use the pressure of the upper bead breaking
roller and of the adjustable roller holding arm.

stepping on its pedal, until the bead enters the cen-
tre groove of the rim, in order to eliminate yielding of
the bead.
2.
Rotate the tightening flange stepping on its pedal
until the bead is completely mounted.
i
Be sure that the lower tire bead slides in the semi
drop centre passing close to the rim edge.
3.
Release the adjustable roller holding arm from the
handle with screws and bring it in position.
4.
Tilt downwards the upper bead breaking roller and
move it downwards with the right control lever
switch on the hydraulic control unit.

The fine positioning (close up to just 5mm distan-
ce from the edge of the rim) is done with the right
and central control lever switches of the hydraulic
control unit.
5.
Check the positioning of the adjustable roller hol-
ding arm and lock it by means of the handle with
