Preliminary Checks; Deciding From Which Side Of The Wheel The Tyre Must Be Demounted - Mondolfo Ferro AS 924 Manual De Uso

Use only original accessories and spare parts provided by the Manufacturer to
prevent the risk of damage or uncontrolled movements of the machine.

8.1. 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 function properly.
Check that the machine has been connected correctly to the mains electricity supply and
the compressed air supply
8.2. DECIDING FROM WHICH SIDE OF THE WHEEL THE TYRE
MUST BE DEMOUNTED
See Fig.13. Identify the position of rim well A on the
wheel. Find the largest width B and the smallest
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
Alloy rim wheels: some alloy rim wheels have minimal
rim wells A or no rim wells at all - Fig. 13A. These rims
are not approved by DOT (Department of Transport-
ation) standards. 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 a 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 the area
of the valve hole, on both the top and bottom sides.
