7.2 PREPARING THE FUEL BLEND

This machine is equipped with a 2-stroke engine
that requires a blend of petrol and lubricating oil.
IMPORTANT Using petrol alone damages
the engine and will void the warranty.
IMPORTANT Use only high quality fuels
and lubricants to maintain performance and
ensure the durability of mechanical parts.
7.2.1 Petrol - characteristics
Use only unleaded petrol (green petrol)
with an octane of no less than 90 N.O.
IMPORTANT Green petrol tends to create
deposits in the container if stored for more
than 2 months. Always use fresh petrol!
7.2.2 Oil - characteristics
Use only high quality synthetic oil
specific for 2-stroke engines.
Your Dealer will have oils specially
designed for this type of engine which can
guarantee a high level of protection.
Using these oils allows a 2.5% blend to be used,
comprising 1 part oil for every 40 parts petrol.
7.2.3 Preparing and storing the fuel blend
Preparing the fuel blend
1. add approximately half of the amount
of petrol to a type-approved canister;
2. add all the oil;
3. add the rest of the petrol;
4. close the cap and shake vigorously.
IMPORTANT The fuel blend is subject to
ageing. Do not prepare excessive quantities of
fuel blend to prevent the formation of deposits.
