• Secure the rim to the mandrel according to the proce-
dure described in paragraph “WHEEL CLAMPING”.
• Adequately lubricate the tyre beads and the rim bead
seat with a suitable lubricant using the provided
brush.
USE ONLY TYRE LUBRICANTS.
SUITABLE LUBRICANTS CONTAIN
NO WATER, HYDROCARBONS, OR
SILICON.
• Mount the grippers (on demand) (
Fig. 27 pos. 1
) on
the external edge of the rim in the highest point as
shown in
Fig. 27
.
THE GRIPPERS MUST BE TIGHTLY
SECURED TO THE EDGE OF THE
RIM.
• Move to work position
B
(
Fig. 11
).
• Position the tyre near the machine and lower the
mandrel (make sure that the grippers are in the high-
est point) to hook the first tyre bead (internal bead).
• Lift the mandrel with the tyre hooked and turn it
clockwise by about 15-20 cm; the tyre will position
itself sideways with respect to the rim.
• Bring the roll holder arm in the “out of work” position
(
Fig. 18 pos. 1
); by operating on the handle control
position the roll holder arm on the internal side of
the wheel then bring it back into “working” position
(
Fig. 17 pos. 1
) and lock it with the special safety pin.
PAY ATTENTION WHEN REPOSI-
TIONING THE ROLL HOLDER ARM
TO AVOID HAND CRUSHING.
ALWAYS MAKE SURE THAT THE
ARM IS CORRECTLY LOCKED TO
THE SHIFTING BEAM.
• Mount the hook tool turned towards the tyre in order
to insert the same hook between the rim edge and the
tyre bead; the operation must be carried out during
the mandrel rotation.
• Move to work position
C
(
Fig. 11
).
• Move the tool forward until the axis of the reference
notch matches that of the external edge of the rim at
about 5 mm from the rim itself (see
Fig. 33
).

• Move to work position
B
(
Fig. 11
).
• From the external side of the wheel, check the exact
position of the tool and, if necessary, correct it. Then,
turn the mandrel clockwise until the grippers reach
in the closest point to the tool (11 o’clock). The first
bead should now be inserted in the rim, therefore
remove the grippers.
• Move to work position
C
(
Fig. 11
).
• Extract the tool hook from the tyre.
• Place the roll holder arm in “out of work” position
(
Fig. 18 pos. 1
) and translate it to the outer side of
the tyre.
• Remount the hook tool with a 180° rotation, accord-
ing to the descriptions in the relevant paragraph.
• Move to work position
A
(
Fig. 11
).
• Turn the mandrel to position the hole to insert the
valve downward (6 o’clock).
• Lower the mandrel until the wheel is laid down to the
ground in order to create the space needed between
tyre edge and rim for the air chamber introduction.
THE VALVE HOLE COULD BE
IN AN ASYMMETRIC POSITION
WITH RESPECT TO THE CENTRE
OF THE RIM. IN THIS CASE IT IS
NECESSARY TO POSITION AND
INTRODUCE THE INNER TUBE
AS SHOWN IN FIGURE 34.
