7.2 PREPARING THE FUEL MIXTURE

This machine has a two-stroke engine which requires a mixture of petrol and lubricating oil.EN - 10 IMPORTANT Using petrol alone will damage the engine and will void the warranty. IMPORTANT Only use quality fuels and oils to maintain high performance and guarantee the duration of the mechanical parts over time.

7.2.1 Petrol characteristics

Only use unleaded petrol with an octane rating of at least 90. IMPORTANT Unleaded petrol tends to create deposits in the container if stored for more than 2 months. Always use fresh petrol!

7.2.2 Oil characteristics

Only use top quality synthetic oil that is specically for two-stroke engines, with minimum JASO FC specications. Your Dealer can provide you with oils which have been specically developed for this type of engine, and which are capable of guaranteeing a high level of protection. The use of these oils makes it possible to prepare a 2.5% mixture, consisting of 1 part oil to 40 parts petrol.

7.2.3 Preparation and storage

of the fuel mixture The chart indicates the amount of petrol and oil to use to prepare the fuel mixture. Petrol 2-stroke synthetic oil litres litres

To prepare the fuel mixture:

1. Place about half the amount of

petrol in a homologated tank.

3. Add the rest of the petrol.

4. Close the top and shake well.

IMPORTANT The fuel mixture tends to age. Do not prepare excessive amounts of the fuel mixture to avoid the formation of deposits. IMPORTANT Keep the petrol and fuel mixture containers separate and easily identiable to avoid the mistake of using one in place of the other. IMPORTANT Periodically clean the petrol and fuel mixture containers to remove any deposits.

Refuelling must take place when the machine is switched o and the spark plug cap removed. Before refuelling:

1. Shake the fuel mixture container well.

2. Place the machine on a at stable surface,

with the fuel tank cap facing upwards. NOTE On the fuel mixture tank (Fig. 11.A) there is the following symbol: Fuel mixture tank

3. Clean the fuel tank cap and the

surrounding area to prevent any dirt from entering the tank during refuelling.

4. Open the fuel tank cap carefully to allow

the pressure inside to decrease gradually.

5. Use a funnel to rell and avoid

lling the tank to the brim.

7.4 CLEANING THE MACHINE

To reduce re hazards, keep the machine and, in particular, the engine free of leaves and branches.
