Fuelling
WARNING!The following precautions reduce
the risk of fire:
the risk of fire:
• Do not smoke or place any sources of heat in
the vicinity of the fuel.
• Never refuel when the engine is running.
• Open the fuel cap slowly when fuelling so
• Open the fuel cap slowly when fuelling so
that any over pressure is released slowly.
• Tighten the fuel cap carefully after refuelling.
• Always move the machine from the fuelling
• Always move the machine from the fuelling
place before starting.
• Keep the handle dry, clean
and free from oil and fuel.
• Clean around the fuel cap.
Clean the fuel tank
regularly. The fuel filter
should be changed at least
once per year
Contamination in the tank
can disrupt operations.
Ensure that the fuel is well
mixed by shaking the
container before filling the
tank.

IMPORTANT! The machine is equipped with a two-stroke
engine and must always been run using a mixture of gasoline
and two-stroke engine oil. It is important to accurately measure
the amount of oil to be mixed to ensure that the correct mixture
is obtained. When mixing small amounts of fuel, even small
inaccuracies can drastically affect the ratio of the mixture.

Petrol
• Use good quality unleaded
or leaded petrol.
• The lowest octane
recommended is 90 (RON).
If you run the engine on a
lower octane grade than 90
so-called knocking can
occur. This gives rise to a
high engine temperature,
which can result in serious
engine damage
