FUEL HANDLING
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 environment 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 (K760)
•
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.
Mixing ratio (K760 OilGuard)
•
1:50 (2 %) with HUSQVARNA OilGuard oil

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 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 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.
