3. By means of the hydraulic control unit joystick, lift
the tool, rotate it and position it on the upper edge
of the rim, using the central button (AUTO) of the
hydraulic control unit.
!
The curved part of the tool has to match the rim.
4. While operating the locking flange pedal, keep rota-
ting the tightening flange until the upper tire bead
has passed close to the mounting tool and it has
gone underneath the rim edge.
i
Ensure that the upper heel of the tyre slides in the
semi drop centre passing near the rim edge. To facili-
tate this operation we recommend aiding the mano-
euvre by lightly pressing on the tyre with the hands.
5. 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-
cking flange pedal) to mount completely the tire.
i
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.
