• 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
(

).
• 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.
With hook tool
Proceed as follows:
• 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 grippers (
Fig.
_
29 ref.
_
1
) on the external edge
of the rim in the highest point
.
THE GRIPPERS MUST BE TIGHTLY
SECURED TO THE EDGE OF THE
RIM.
• Move to work position
B
(
Fig.
_
6
).
• Lower the mandrel arm completely. Roll the tyre on
the platform and hook it to clamp (
Fig.
_
30 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.
_
30
).
• Place the tool holder arm in “off-work” position
(
Fig.
_
15 ref.
_
1
); translate it to the inner side of the
tyre and hook it again into work position (
Fig.
_
14
ref.
_
1
).
• Carry out the tools head 180° rotation until the hook
tool is moved onto the tyre side (see
Fig.
_
32
).

• Move to work position
D
(
Fig.

).
• Move the tool forward until the reference notch
matches the external edge of the rim coincide at about
5 mm from the rim itself.
• Move to work position
C
(
Fig.
_
6
).
• 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
the lowest point (6 o’clock). The first bead should
now be inserted in the rim.
• Remove the grippers.
• Move to work position
D
(
Fig.
_
6
).
• Extract the tool from the tyre.
• Place the tool holder arm in “off-work” position
(
Fig.
_
15 ref.
_
1
); translate it to the outer side of the
tyre and hook it again into “work” position (
Fig.
_
14
ref.
_
1
).
• Carry out the tools head 180° rotation until the hook
tool is moved onto the tyre side (see
Fig.

).
