FUEL HANDLING
General
Fuel
Gasoline
Use good quality 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.
Environment fuel
The use of environmentl fuel (alkylate fuel), or environment 
fuel for four-stroke engines blended with two-stroke oil as set 
out below is recommended.
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.
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.
Mixing
Always mix the gasoline and oil in a clean container 
intended for fuel.
Always start by filling half the amount of the gasoline to be 
used. Then add the entire amount of oil. Mix (shake) the 
fuel mixture. Add the remaining amount of gasoline.
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.
Mixing ratio
1:50 (2%) for all engines.
Fueling
Never start the machine:
If you have spilled fuel or chain oil on the machine. Wipe 
off the spillage and allow remaining fuel to evaporate.
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.
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.
!
WARNING! Running an engine in a confined 
or badly ventilated area can result in death 
due to asphyxiation or carbon monoxide 
poisoning. Use fans to ensure proper air 
circulation when working in trenches or 
ditches deeper than one meter (3 foot).
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.
The exhaust fumes from the engine are hot 
and may contain sparks which can start a 
fire. Never start the machine indoors or near 
combustible material!
Do not smoke and do not place any hot 
objects in the vicinity of fuel.
NOTICE! The machine is equipped with a two-stroke 
engine and must always been 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! Always stop the engine and let it 
cool for a few minutes before refuelling. The 
engine should be switched off, and the stop 
switch in STOP position.
When refuelling, open the fuel cap slowly so 
that any excess pressure is released gently.
Clean the area around the fuel cap.
Tighten the fuel cap carefully after refuelling. 
Negligence may lead to the start of a fire.
Move the machine at least 10 ft (3 m) from 
the refuelling point before starting it.
