Fuel safety

Never start the machine:
1 If you have spilled fuel on it. Wipe off the spillage and
allow remaining fuel to evaporate.
2 If you have spilled 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.
3 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 open 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 gas 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.
• In order to prevent unintentional starting of the engine,
the spark plug cap must always be removed during
long-term storage, if the machine is not under close
supervision and when performing all service
measures.
WARNING! Take care when handling fuel.
!
Bear in mind the risk of fire, explosion
and inhaling fumes.

Fuel

CAUTION! The machine is equipped with a two-stroke
engine and must always be 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.
WARNING! Fuel and fuel fumes are
!
highly flammable 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.

FUEL HANDLING

Gasoline
CAUTION! Always use a quality gasoline/oil mixture with
an octane rating of at least 87 octane ((RON+MON)/2). If
your machine is equipped with a catalytic converter (see
chapter on Technical data) always use a good quality
unleaded gasoline/oil mixture. Leaded gasoline will
destroy the catalytic converter.
Use low-emission gasoline, also known as alkylate
gasoline, if it is available.
Ethanol blended fuel, E10 may be used (max 10%
ethanol blend). Using ethanol blends higher than E10 will
create lean running condition which can cause engine
damage.
This engine is certified to operate on unleaded
gasoline.
• The lowest recommended octane grade is 87
((RON+MON)/2). If you run the engine on a lower
octane grade than 87 so-called knocking can occur.
This gives rise to a high engine temperature and
increased bearing load, which can result in serious
engine damage.
• When working at continuous high revs a higher octane
rating is recommended.
Two-stroke oil
• For best results and performance use HUSQVARNA
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
50:1 (2%) with HUSQVARNA two-stroke oil.
