WARNING: Read and understand the safety
chapter before you use the product.
Fuel
To use fuel
CAUTION: This product has a two-stroke
engine. Use a mixture of gasoline and two-
stroke engine oil. Make sure to use the
correct quantity of oil in the mixture.
Incorrect ratio of gasoline and oil can cause
damage to the engine.
Husqvarna alkylate fuel
CAUTION: Do not use gasoline with an
octane number less than 90 RON (87 AKI).
This can cause damage to the product.
CAUTION: Do not use gasoline with more
than 10% ethanol concentration (E10). This
can cause damage to the product.
CAUTION: Do not use leaded gasoline. This
can cause damage to the product.
We recommend Husqvarna alkylate fuel for best
performance. This fuel gives less dangerous exhaust
fumes compared to regular fuel. It keeps the engine
clean and increases the engine life. Husqvarna alkylate
fuel is not available in all commercial areas.
• Always use new unleaded gasoline with a minimum
octane number of 90 RON (87 AKI) and with less
than 10% ethanol concentration (E10).
• Use gasoline with a higher octane number if you
frequently use the product at continuously high
engine speed.
• Always use a good quality unleaded gasoline/oil
mixture.
Two-stroke oil
• For best results and performance use Husqvarna
two-stroke oil, which is specially formulated for our
two-stroke engines.
• If Husqvarna two-stroke oil is not available, use a
different two-stroke oil of good quality that is
formulated for air-cooled engines. Consult your
servicing dealer when you select an oil.
