FUEL HANDLING
14 – English
General
Fuel
Petrol
Use good quality unleaded or leaded petrol.
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.
Environment fuel
HUSQVARNA recommends the use of alkylate fuel, 
either Aspen two-stroke fuel or environmental fuel for 
four-stroke engines blended with two-stroke oil as set out 
below. Note that carburettor adjustment may be 
necessary when changing the type of fuel (see the 
instructions under the heading Carburettor).
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
K760
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.
K760 OilGuard
Use HUSQVARNA OilGuard two stroke oil.
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.
Mixing ratio
1:50 (2%) with HUSQVARNA two-stroke oil or 
equivalent.
1:33 (3%) with oils class JASO FB or ISO EGB 
formulated for air-cooled, two-stroke engines or mix 
as per recommendation from the oil manufacturer.
!
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.
Fuel and fuel fumes are 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.
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 
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.
