12.0 USING THE MACHINE
12.1 Precaution measures during tyre re-
moval and fitting
Before fitting a tyre, observe the following safety rules:
• always use clean, dry and in good condition rims
and tyres; in particular, if necessary, clean the rims
after all the balancing weights (as well as the adhesive
weights on the inner side) have been removed, and
make sure that:
- neither the bead nor the tread of the tyre are dam-
aged.
- the rim does not produce dents and/or deformation
(especially for alloy rims, dents can cause internal
micro-fractures, that pass unobserved at visual
inspection, and can compromise 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 COMPLETE-
LY DEFLATE.
• Establish from which side the tyre should be de-
mounted, checking the position of the groove.
• Find the rim locking point.
• Try to establish the special types of wheels, such as
“TD” and “AH”, in order to improve locking, bead
breaking, assembly and disassembly performances.
12.3 Bead breaking with side vane
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. 20
and move
the bead breaker tool toward the edge of the rim.
Fig. 20
2. Press the pedal (
Fig. 19 ref. 4
) and activate the
bead breaker tool to remove the bead. If the bead
does not detach the first time, repeat the operation,
on different points of the wheel, until it has come
away completely.
3. Reverse the position of the wheel and repeat the
operation on the other side.
4. Lubricate the tyre carefully along the entire circum-
ference of the bead on both sides.
FAILURE TO LUBRICATE MIGHT
CAUSE FRICTION BETWEEN THE
MOUNTING TOOL AND THE TYRE,
AND WOULD CAUSE DAMAGE TO
THE TYRE AND/OR THE BEAD.
