FUEL HANDLING
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
•
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.
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 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.
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.
•
If the machine is not used for some time the fuel tank
should be emptied and cleaned.
Fuelling
•
Keep the handle dry and free from oil and fuel.
•
Ensure that the fuel is well mixed by shaking the container
before filling the tank.
•
Always exercise care when refilling the fuel. Move the
machine at least three metres from the fuelling area
before it is started. Check that the fuel cap is tightened
correctly.
•
Clean around the fuel cap. Clean the fuel and oil tank
regularly. The fuel filter should be changed at least once a
year. Contamination in the tanks causes malfunction.
!
WARNING! Always ensure there is adequate
ventilation when handling fuel.

WARNING! Taking the following precautions,
will lessen the risk of fire:
Do not smoke or place hot objects near fuel.
Always shut off the engine before refuelling.
When refuelling, open the fuel cap slowly so
that any excess pressure is released gently.
Tighten the fuel cap carefully after refuelling.
Always move the machine away from the
refuelling area before starting.
