FUEL HANDLING

14 – English

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. In the event of 
leakage, contact your service agent.

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. Drain the 
tank into the appropriate containers and in a well 
ventilated area.

•

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.

•

Allow the machine to cool before putting it in storage.

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.

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 the 
catalytic converters.

•

Mixing ratio

50:1 (2%) with HUSQVARNA two-stroke oil.

!

WARNING! Take care when handling fuel. 
Bear in mind the risk of fire, explosion 
and inhaling fumes.

!

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.

!

WARNING! Always ensure there is 
adequate ventilation when handling fuel.
