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
dangerous exhaust fumes. The fuel gives a low quantity
of dangerous remainings when it is combusted, which
keeps the components of the engine more clean. This
extends the life of the engine. Husqvarna alkylate fuel is
not available in all markets.
Two-stroke oil
CAUTION: Unsatisfactory oil quality
and/or incorrect oil/fuel ratio can damage
the product and decrease the life time of
catalytic converters.
CAUTION: Do not use two-stroke oil
for water-cooled outboard engines, also
referred to as outboard oil.
CAUTION: Do not use oil for four-stroke
engines.
For best results and performance use Husqvarna
two-stroke oil.
If Husqvarna two-stroke oil is not available, use a
different two-stroke oil of good quality for air-cooled
engines. Speak to your servicing dealer to select the
correct oil.

To mix gasoline and two-stroke oil
CAUTION:
There is a risk that small
errors influence the ratio of the mixture
drastically when you mix small quantities of
fuel. Carefully measure the quantity of oil
to be mixed to make sure that you get the
correct mixture.
