Operation

5. Remove the cutting attachment guard (A).
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
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.
• We recommend that you use gasoline of a higher
octane grade for work with continuously high rpm.
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.
