IMPORTANT Use only quality fuels and oils to maintain high performance and guarantee the
du-ration of the mechanical parts over time.
2.2.1 Petrol characteristics
Only use unleaded petrol with a fuel grade of at least 90 ON.
IMPORTANT Unleaded petrol tends to create deposits in the container if preserved for more
than 2 months. Always use fresh petrol!
2.2.2 Oil characteristics
Only use top quality synthetic oil specifically for two-stroke engines.
Your Dealer can provide you with oils which have been specifically developed for this type of
en-gine, and which are capable of guaranteeing a high level of protection.

D ANGER! Petrol and the fuel mixture are highly inflammable!
