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.
