Preparing The Fuel Mixture; Using The Machine - Stiga SBC 627 K Manual De Instrucciones

2.2 PREPARING THE FUEL MIXTURE

This machine is fitted with a two-stroke engine
which requires a mixture of petrol and lubricat-
ing oil.
IMPORTANT Using petrol alone will damage the
engine and is cause for invalidation of the war-
ranty.
IMPORTANT Use only quality fuels and oils to
maintain high performance and guarantee the du-
ration of the mechanical parts over time.
2.2.1 Petrol characteristics
Only use unleaded petrol with a fuel grade of at
least 90 ON.
IMPORTANT Unleaded petrol tends to create de-
posits in the container if preserved for more than 2
months Always use fresh petrol!
2.2.2 Oil characteristics
Only use top quality synthetic oil specifically for
two-stroke engines.
Your Dealer can provide you with oils which have
been specifically developed for this type of en-
gine, and which are capable of guaranteeing a
high level of protection.
The use of these oils makes it possible to pre-
pare a 2% mixture, consisting in 1 part oil to 50
parts petrol.
2.2.3 Preparation and preservation
of the fuel mixture
DANGER! Petrol and the fuel mixture are
highly inflammable!
– K eep the petrol and fuel mixture in homolo-
gated fuel containers, in a safe place, away
from any flames or heat sources.
– Never leave the containers within the reach
of children.
– N ever smoke whilst preparing the mixture
and avoid inhaling the petrol fumes.
To prepare the fuel mixture:
– Place about half the amount of petrol in a ho-
mologated tank.
– Add all the oil, according to the chart.
– Add the rest of the petrol.
– 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 identifiable to
avoid the mistake of using one in place of the
other.
IMPORTANT Periodically clean the petrol and
fuel mixture containers to remove any eventual
deposits.
2.3 REFUELLING
DANGER! Never smoke whilst refuelling
and avoid inhaling the petrol fumes.
WARNING! Carefully open the tank top
as pressure could have formed inside.
Before refuelling:
– Shake the fuel mixture container well.
– Place the machine on a flat stable surface,
with the fuel tank cap facing upwards.
– Clean the fuel tank cap and the surrounding
area to avoid any dirt from entering the tank
during refilling.
– Carefully open the fuel tank cap to allow the
pressure inside to decrease gradually. Use
a funnel to refill and avoid filling the tank to
the brim.
WARNING! Always close the fuel tank
cap firmly.
WARNING! Immediately clean all traces
of fuel which may have dripped on the ma-
chine or the ground and do not start the en-
gine until the petrol fumes have dissipated.

3. USING THE MACHINE
