maintain high performance and guarantee the du-
ration of the mechanical parts over time.
2.2.1 Petrol characteristics

posits in the container if preserved for more than 2
months. Always use fresh petrol!

– Keep the petrol in homologated fuel con-
tainers, in safe place, away from any flames
or heat sources.
– Never leave the containers within the reach
of children.

inadequate oil or one with different features to
those indicated will damage the motor and will
cause invalidation of the warranty
