Operation
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.
Gasoline
CAUTION: Always use a quality gasoline/oil
mixture of at least 90 octane (RON). There
is a risk that use of lower octane grade
causes knocking. This gives rise to high
engine temperature, which can result in
serious engine damage.
CAUTION: If your product is equipped with a
catalytic converter use a good quality
unleaded gasoline/oil mixture. Leaded
gasoline will destroy the catalytic converter.
• Use low-emission gasoline, also know as alkylate
gasoline, if it is available.
• Ethanol blended fuel, E10 may be used (max 10%
ethanol blend). Using ethanol blends higher than
E10 will cause lean running condition which can
damage the engine.
• We recommend a higher octane rating when you do
work at continuous high speed.
Husqvarna alkylate fuel
We recommend you to use Husqvarna alkylate fuel for
best performance. The fuel contains less dangerous
material compared to regular fuel, which decreases
