FUEL HANDLING
Fuel mixture
CAUTION! The machine is equipped with
a two--stroke engine and must always be
run using a mixture of gasoline and two--
stroke engine oil. It is important to accu-
rately measure the amount of oil to be
mixed to ensure that the correct mixture is
obtained. When mixing small amounts of
fuel, even small inaccuracies can drastical-
ly affect the ratio of the mixture.
Gasoline
CAUTION! Always use high quality
unleaded gasoline.
S This engine is certified to operate on
unleaded gasoline.
S The lowest recommended octane rating
is 87. If you run the engine on lower oc-
tane rating than 87, “knocking” can oc-
cur. This leads to an increased engine
temperature, which can result in a seri-
ous engine breakdown.
S When working at continuous high revs a
higher octane rating is recommended.
Two--stroke oil
S For great results and performance use
HUSQVARNA two--stroke oil, which is
specially formulated for our two--stroke
engines. Mixture 1:50 (2%).
S To maximize the life of your trimmer, you
may choose to use a high quality syn-
thetic oil formulated for two--stroke
engines. Mixture 1:50 (2%).
S Never use two--stroke oil intended for
water--cooled outboard engines,
sometimes referred to as outboard oil.
S Never use oil intended for four--stroke
engines.
WARNING: Fuel and fuel fumes
are highly flammable and can cause
serious injury when inhaled or al-
lowed to come in contact with the
skin. For this reason, observe cau-
tion when handling fuel and make
sure there is adequate ventilation.
