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
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

frequently use the product at continuously high
engine speed.
• Always use a good quality unleaded gasoline/oil
mixture.
Two-stroke oil
