• Mount grippers (
Fig. 39 ref. 1
) on the external edge
of the rim in the highest point as shown in
Fig. 39
.

THE GRIPPERS MUST BE TIGHTLY
SECURED TO THE EDGE OF THE
RIM.
• Move to work position
B
(
Fig. 8
).
• Lower the mandrel arm completely. Roll the tyre on
the platform and hook it to clamp (
Fig. 40 ref. 1
)
.
• Lift the mandrel arm with the tyre hooked and turn
it counterclockwise by about 15-20 cm; the tyre
will position itself sideways with respect to the rim
Fig. 40
).

• Move to work position
C
(
Fig. 8
).
• Position beading disc (
Fig. 41 ref. 2
) so that it is
at approximately 1.5 cm (½”) from the edge of the
rim. Fitting clamp (
Fig. 41 ref. 1
) is at 11 o’clock.
Turn the mandrel until the grippers reach the lowest
point (6 o’clock).

• Move the beading disc away from the wheel.
• Remove the grippers and fit them in the same posi-
tion (6 o’clock) outside the second bead.
• Turn the mandrel 90° clockwise until the grippers
are at 9 o’clock.
• Move the beading disc forward until it is inside the
edge of the rim by about 1-2 cm, making sure it is
approximately 5 mm from the profile. Begin clock-
wise rotation making sure that, after a 90° turn, the
second bead begins to slide in the rim groove.
• Once insertion is completed, move the tool away from
the wheel, turn it over into “out of work” position and
remove the grippers.
• Lower the mandrel until the wheel rests on the
footboard.
• Move to work position
A
(
Fig. 8
).
• Close the mandrel jaws completely, making sure the
wheel is held up to avoid dropping.
MAKE SURE THAT THE WHEEL’S
HOLD IS SECURE TO AVOID IT
FALLING DURING REMOVAL. FOR
HEAVY AND/OR VERY LARGE
WHEELS USE AN ADEQUATE LIFT-
ING DEVICE.
• Translate the movable footboard to release the wheel
from the same mandrel. With especially soft tyres,
simultaneously insert both beads on the jaw so that
bead insertion in the tyre is done only once; this
single operation is ideal for saving time.
