FUEL HANDLING
Fuel safety
Never start the machine:
●
If you have spilt fuel on it. Wipe off the spillage and
allow remaining fuel to evaporate.
●
If you have spilt fuel on yourself or your clothes,
change your clothes. Wash any part of your body
that has come in contact with fuel. Use soap and
water.
●
If the machine is leaking fuel. Check regularly for
leaks from the fuel cap and fuel lines.
Transport and storage
● Store and transport the machine and fuel so that
there is no risk of any leakage or fumes coming into
contact with sparks or naked flames, for example,
from electrical machinery, electric motors, electrical
relays/switches or boilers.
●
When storing and transporting fuel always use
approved containers intended for this purpose.
●
When storing the machine for long periods the fuel
tank must be emptied. Contact your local petrol
station to find out where to dispose of excess fuel.
● Ensure the machine is cleaned and that a complete
service is carried out before long-term storage.
● The transport guard must always be fitted to the
cutting attachment when the machine is being
transported or in storage.
● Secure the machine during transport.
a
WARNING:
Take care when handling fuel.
Bear in mind the risk of fire, explosion and
inhaling fumes.
Fuel
a
WARNING:
Fuel and fuel fumes are highly
inflammable and can cause serious injury when
inhaled or allowed to Come in contact with the
skin. For this reason observe caution when
handling fuel and make sure there is adequate
ventilation.
CAUTION:
The machine is equipped with a
two-stroke engine and must always been run using
a mixture of petrol and two-stroke 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
CAUTION:
Always use a quality petrol/oil mixture
at least 87 octane [(R+M)/2]. If your machine is
equipped with a catalytic converter (see chapter on
Technical data) always use a good quality unleaded
petrol/oil mixture. Leaded petrol will destroy the
catalytic converter.
● The lowest octane recommended is 87 octane
[(R+M)/2]. If you run the engine on a lower octane
grade gasoline, so-called knocking can occur. This
gives rise to a high engine temperature, which can
result in serious engine damage.
●
When working at continuous high revs a higher
octane rating is recommended.
● Ethanol blended fuel (E10 or less) may be used.
Using ethanol blends higher than E10 will create
lean running condition which can cause engine
damage.
Two-stroke oil
● For best results and performance use JONSERED
two-stroke engine oil, which is specially formulated
for our air-cooled two-stroke engines.
●
Never use two-stroke oil intended for water-cooled
engines, sometimes referred to as outboard oil
(rated TCW).
●
Never use oil intended for four-stroke engines.
● A poor oil quality and/or too high oil/fuel ratio may
jeopardise function and decrease the life time of
catalytic converters.
● Mixing ratio is 50:1 (2%).

Mixing
●
Always mix the petrol and oil in a clean container
intended for fuel.
● Always start by filling half the amount of the petrol
to be used. Then add the entire amount of oil. Mix
(shake) the fuel mixture. Add the remaining amount
of petrol.
● Mix (shake) the fuel mixture thoroughly before filling
the machine’s fuel tank.
●
Do not mix more than one month’s supply of fuel
at a time.
●
If the machine is not used for some time the fuel
tank should be emptied and cleaned.
