12.6.3 Mounting
WHEN DEMOUNTING VERY HE-
AVY TYRES, IT IS IMPORTANT TO
MOVE THE WHEEL AS CLOSE AS
POSSIBLE TO THE BASE BEFORE
COMPLETING THE OPERATION.
THROUGHOUT TYRE MOUNTING/
DEMOUNTING OPERATIONS,
CHECK THAT THE SELF-CEN-
TRING CHUCK CLAMPING PRES-
SURE IS CLOSE TO THE MAXIMUM
OPERATING VALUE (160 - 180
BAR).
Tubeless tyre fitting is normally done with the disc tool;
if the wheel is especially hard to fit, use the hook tool.
With beading disc
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
SILICONE.
• Mount grippers (
Fig. 41 ref. 1
) on the external edge
of the rim in the highest point as shown in
Fig. 41.

ALWAYS MAKE SURE THAT THE
ARM IS CORRECTLY HOOKED TO
CARRIAGE.
• Move to work position
D
(
Fig. 12
).
• Carry out the tools holder head 180° rotation in order
to insert the hook tool (
Fig. 40 ref. 1
) between rim
edge and tyre bead.

• Move the rim away from the tool by about 4-5 cm
to avoid possible unhooking of the bead from the
same tool.
• Move to work position
B
(
Fig. 12
).
• Translate the hook tool outwards to allow easy inser-
tion of the lever between the rim and the bead on the
tool left. Keeping the lever pressed, lower the wheel
until the edge of the rim is 5 mm distant from the
hook tool then turn the mandrel counterclockwise
until the tyre has been completely removed.
THE REMOVAL OF THE BEADS
FROM THE RIM CAUSES THE
TYRE TO FALL. ALWAYS MAKE
SURE THAT NO ONE IS STAN-
DING BY ACCIDENT IN THE WORK
AREA.
