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 of a good
quality, for best performance and extension of the

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.

• We recommend that you use gasoline of a higher
octane grade for work with continuously high rpm.
Two-stroke oil

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.
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.
CAUTION: Small errors can influence the
ratio of the mixture drastically when you mix
small quantities of fuel. Measure the quantity
of oil carefully and make sure that you get
the correct mixture.
