Operator manual
In order to prevent damage or involuntary movement of the machine, it is
recommended to only use original manufacturer spare parts and accessories.
WARNING
9.1. PRELIMINARY CHECKS
Check that there is a pressure of at least 8 bar on the filter regulator pressure gauge.
If the pressure is below the minimum level, some machine operations may be limited
or insufficient.
After the correct pressure has been restored, the machine will operate properly.
Check that the machine has been adequately connected to the electric mains and the
pneumatic supply.
9.2. DECIDING FROM WHICH SIDE OF THE WHEEL THE TYRE
MUST BE REMOVED
See Fig.13. Identify the position of channel A on the
rims. Identify the greater width B and the smaller width
C. The tyre must be mounted and demounted with
the wheel on the turntable with the smallest width
side C facing upwards.
SPECIAL WHEELS
Wheels with alloy rims: some wheels with alloy rims
have a minimum A rim channel or do not have any
channel -
Fig. 13A . These rims are not approved by
DOT standards (Department of Transportation). The
DOT initials certify that tyres comply with the safety
standards adopted by the United States and Canada
(these wheels cannot be sold in these markets).
High performance wheels (asymmetric curvature) -
Fig. 13B
some European wheels have rims with very
pronounced curvature C, except in the area of the
valve hole A where the curvature is less pronounced
B. On these wheels the bead must first be broken in
correspondence of the valve hole, on both the top
and bottom sides.
