FUEL HANDLING
Fuel
CAUTION! 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.
Gasoline
CAUTION!
Always use high grade unleaded oil mixed gasoline (minimum
87 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 and it will no longer serve its purpose.
• This engine is certified to operate on unleaded
gasoline.
• The lowest recommended octane rating is 87. If you run
the engine on lower octane rating than 87 so-called
“knocking“ can occur. This leads to an increased engine
temperature, which can result in a serious engine
breakdown.
• When working at continuous high revs a higher octane
rating is recommended.
Two-stroke oil
• For best results and performance use HUSQVARNA two-
stroke oil, which is specially formulated for our two-stroke
engines. Mixture 1:50 (2%).
• Never use two-stroke oil intended for water-cooled
outboard engines, sometimes referred to as outboard oil.
• 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.
• If the machine is not used for some time the fuel tank
should be emptied and cleaned.
• This engine is certified to operate on unleaded
gasoline.
Fuelling
• Move the machine at least 3 m from the refuelling point
before starting it.
• Clean the area around the fuel cap. Contamination in the
tank can cause operating problems.
• Ensure that the fuel is well mixed by shaking the container
before filling the tank.
!
WARNING! Always ensure there is adequate
ventilation when handling fuel.

WARNING! The catalytic converter muffler
gets very hot during and after use. This also
applies during idling. Be aware of the fire
hazard, especially when working near
flammable substances and/or vapours.
!
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.
Always stop the engine and let it cool for a
few minutes 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.
