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.

octane number less than 90 RON (87 AKI).
This can cause damage to the product.
