!
Before demounting or mounting operations it is ext-
remely important to collect all the rim and tire data.
In this way it will be possible to know in advance the
mounting, the pressure and the required accessories!

Remove all the balancing weights on the rim.
i
If the semi drop centre of the rim is placed in the
lower part it is necessary to insert a lock cover (see
chap. 3.3) on the flanged plate, because in this case
the rim leans on its side during rotation.
