Fuel
To use fuel
CAUTION: This product has a two-cycle
engine. Use a mixture of gasoline and two-
cycle 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
We recommend you to use Husqvarna alkylate fuel for
best performance. The fuel contains less dangerous
material compared to regular fuel, which decreases
dangerous exhaust fumes. The fuel gives a low quantity
of dangerous remainings when it is combusted, which
keeps the components of the engine more clean. This
extends the life of the engine. Husqvarna alkylate fuel is
not available in all markets.
Gasoline
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.
• 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-cycle engine oil
• Use only the two-cycle engine oil of high quality,
especially HUSQVARNA two-cycle oil. Use only the
oil of an air cooled engine.
• Mixture ratio 50:1 (2%).
• Oil of low quality and high oil/fuel ratio can decrease
the lifetime of catalytic converters.
• Speak to your dealer when you select an oil.
• If Husqvarna two-stroke oil is not available, you can
use another two-stroke oil of good quality that is
intended for air cooled engines. Contact your dealer
when you select oil.

• Do not use the two-stroke oil for water-cooled
outboard engines. The two-stroke oil is sometimes
referred to as outboard oil.
