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.
Limbing is an example of such work.
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.
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.
