Fuel
This product has a two-stroke engine.
CAUTION: Incorrect type of fuel can result in
engine damage. Use a mixture of gasoline
and two-stroke oil.
Premixed fuel
Use Husqvarna premixed alkylate fuel for best
performance and extension of the engine life. This
fuel contains less harmful chemicals compared to
regular fuel, which decreases harmful exhaust
fumes. The quantity of remains after combustion is
lower with this fuel, which keeps the components of
the engine more clean.
To mix fuel
Gasoline
Use good quality unleaded gasoline with a maximum
of 10% ethanol contents.
CAUTION:
Do not use gasoline with an
octane grade less than 90 RON/87 AKI.
Use of a lower octane grade can cause
engine knocking, which causes engine
damages.
Two-stroke oil
For best results and performance use Husqvarna
two-stroke oil.
If Husqvarna two-stroke oil is not available, use a
two-stroke oil of good quality for air-cooled engines.
Speak to your servicing dealer to select the correct
oil.
CAUTION: Do not use two-stroke oil for
water-cooled outboard engines, also
referred to as outboard oil. Do not use oil
for four-stroke engines.
