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 condi-
tion; if necessary, remove the balancing weights and
clean the rim. Check 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, using 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;
on the contrary, never fit a tyre unless you are sure it
is of 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.
• Establish from which side the tyre should be de-
mounted, checking the position of the groove.
• Find the rim locking type.
• Try to establish the special types of wheels, such as
“EH2” and “EH2+”, in order to improve locking, bead
breaking, assembly and disassembly performances.

WEIGHING MORE THAN 10 KG
AND/OR WITH A FREQUENCY
OF MORE THAN 20/30 WHEELS
PER HOUR, A LIFTING DEVICE
SHOULD BE USED.
12.3 Wheel clamping
All wheels must be locked on the rubber plate (
Fig. 17
ref. 1
) through the central hole using the proper locking
ring nut (
Fig. 17 ref. 2
).

IN CASE OF USE OF RIMS WITH-
OUT CENTRAL HOLE, IT’S NECES-
SARY TO USE THE PROPER FIX-
TURE (AVAILABLE ON DEMAND).
To lock a rim proceed as follows:
1. Dowel the wheel (
Fig. 18 ref. 1
) on the rubber plate
and check that the dragging pin (
Fig. 18 ref. 2
)
enter in a hole placed on the rim hub.

IF THE WHEEL HUB IS HIGH-
ER THEN THE DRAGGING PIN
(FIG. 19 REF. 2), USE THE EXTEN-
SION (FIG. 19 REF. 1) SUPPLIED
ON ISSUE.
