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.
IMPORTANT Keep containers of fuel blend
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. 14.G).
NOTE The fuel tank
(Fig. 14.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.
