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.
Green petrol tends to create
IMPORTANT
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.
IMPORTANT To know the percentages of
oil and petrol to be used, see the "TECHNICAL
DATA" table.
Preparing and storing the fuel blend
7.2.3
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.
Keep containers of fuel blend
IMPORTANT
and petrol separate and clearly identified to avoid
swapping them at the time of use.
IMPORTANT Clean the petrol and fuel blend
containers at regular intervals to remove any
deposits.
7.3 REFUELLING
Before refuelling:
1. vigorously shake the canister containing the
fuel blend;
2. place the machine on a level surface in a
stable position with the fuel tank cap facing
upwards (Fig. 19.G).
NOTE The fuel tank (Fig. 19.G) has the
following symbol:
Fuel blend tank.
3. Clean the fuel cap and the surrounding area to
avoid ingress of dirt when refuelling.
4. Carefully open the fuel tank slowly to allow the
pressure to decrease gradually.
5. Refuel using a funnel; do not fill the tank right
to the top.
7.4 CLEANING THE MACHINE AND THE
ENGINE
Always clean the machine after use.
To reduce the risk of fire:
– keep the machine and especially the engine
free from residues of grass, leaves or
excessive grease;
– frequently clean the cylinder fins with
compressed air and eliminate sawdust,
twigs, leaves or other debris from the
silencer area.
To avoid overheating and damage to the engine,
always keep the cooling air vents clean and free of
sawdust or debris.

7.5 NUTS AND BOLTS

• Keep all nuts, bolts and screws tight to be sure
the equipment is in safe working condition.
• Check regularly that the handles are fixed
firmly.
