Special Instructions; Bead Breaking - Corghi A 2030 Manual De Uso

The two sides may be almost identical, but only the narrow side serves for tyre mount-
ing and demounting
Identify the side for tyre mounting and make sure that this side is facing upward when
you install the tyre on the table top (i.e. facing toward the mount/demount head)
Alloy wheels
Some alloy wheels on the market have minimal rim channels or are even completely
without rim channels (these wheels are not DOT approved).

A No rim channel
DANGER
When working these wheels it is possible to damage the tyre, the rim or both, with
the risk of the tyre exploding under pressure causing serious injury or death. When
mounting tyres on this type of wheel, use the utmost caution.
European style high performance wheels (asymmetrical curvature)
Some European wheels have very pronounced curves on the rim edge, except in the area
of the valve hole. On this type of wheel bead breaking must be performed in correspond-
ence with the valve hole and on the lower and upper side of the wheel.

C Pronounced curvature
Wheels for Corvette, BMW, Lamborghini and other wheels with "Low pressure indica-
tor system"
Some types of high performance wheels are equipped with a pressure transmitter se-
cured to the rim with a belt on the side opposite the valve hole. On this type of wheel
bead breaking must be done initially in correspondence with the valve hole, on both
sides of the rim.

- Fully deflate the tyre, removing the valve
(On the A 2020 and A 2025 use lever A fig.10 to adjust the rim support in the correct
position for the width of the wheel the bead of which is to be broken. On the A 2025 and
A 2030 adjust the position of the blade using the lever B, fig. 10a to suite the tyre size
fig. 10c. On the A 2030 use the lever C fig.10a to adjust the angle of the bead breaker
arm as required by the wheel diameter.
- Position the wheel as shown in fig.11 and bring the bead breaker shoe to the edge of
the rim.
