12.0 USING THE MACHINE
12.1 Precaution measures during tyre re-
moval and fitting
Before fitting a tyre, observe the following safety rules:
• rim and tyre must be clean, dry and in good condition.
If necessary, remove the balancing weights and clean
the rim. Check:
- tyre bead and tread for damage.
- rim for dents and/or deformation (especially for alloy
rims, dents can cause internal micro-fractures, that
pass unobserved at visual inspection, and can com-
promise the solidity of the rim and constitute danger
even during inflation).
• adequately lubricate the contact surface of rim and
tyre bead. Use specific tyre lubricants only.
• replace the inner tube valve with a new valve. If the
tyre tube has a metal valve, replace the grommet.
• make sure that the tyre is the right size for the rim.
Never fit a tyre unless you are sure it is the right size
(the rated size of the rim and tyre is usually printed
directly on each of them).
• Do not use compressed air or water jets to clean the
wheels on the machine.
12.2 Preliminary operations - Preparing
the wheel
• Remove the wheel balancing weights from both sides
of the wheel.
REMOVE THE VALVE STEM AND
ALLOW THE TYRE TO COM-
PLETELY DEFLATE.
12.3 Bead breaking
After preparing the wheel as described in the previous
point, follow the instructions given below to carry out
the bead breaking procedure.
1. Position the wheel as indicated in
Fig. 18 and move
the bead breaker tool toward the edge of the rim.
2. Operate the bead breaker shoe by pressing the rela-
tive pedal until the bead has detached. If the bead
does not detach the first time, repeat the operation,
on different points of the wheel, until it has come
completely away.
3. Reverse the position of the wheel and repeat the op-
eration on the other side.
4. Lubricate the tyre carefully along the entire circum-
ference of the bead on both sides. Failure to lubri-
cate might cause friction between the mounting tool
and the tyre, and would cause damage to the tyre
and/or the bead.

NEVER INSERT ANY PART OF YOUR
BODY BETWEEN THE BEAD
BREAKER TOOL AND THE TYRE,
OR BETWEEN THE TYRE AND THE
WHEEL SUPPORT.
• Verify from which side the tyre should be demounted,
checking the position of the channel.
• Find the rim locking type.
• Try to establish the special types of wheels, such as
“TD” and “AH”, in order to improve locking, bead break-
ing, assembly and disassembly performances..
