Operation

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.
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.
WARNING: Always use protective
gloves when you assemble the saw
chain.
To adjust the tension
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.
