FUEL HANDLING
16 – English
Fuel safety
Never start the machine:
1
If you have spilt fuel on it. Wipe off the spillage and 
allow remaining fuel to evaporate.
2
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.
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 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.
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.
Fuel
CAUTION!  The machine is equipped with a two-stroke 
engine and must always been run using a mixture of 
petrol 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
CAUTION!  Always use a quality petrol/oil mixture at least 
90 octane (RON). 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.
Use low-emission petrol, also known as alkylate petrol, if 
it is available. 
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.
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
1:50 (2%) with HUSQVARNA two-stroke oil.
1:33 (3%) with oils class JASO FB or ISO EGB 
formulated for air-cooled, two-stroke engines.
!
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.
