Adjust pressure to the type of tire.

Use the plastic protections on the types of
rim that need it.
!
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 accesso-
ries!
i
Remove all the balancing weights from the rim.
i
If the semi drop centre of the rim is placed in the
inside part it is necessary to insert a cover to the
locking jaws (see chap. 3.3) on the flanged plate,
because in this case the rim leans on its side during
rotation.
