Fuel

CAUTION! The machine is equipped with a two-stroke
engine and must always been run using a mixture of
petrol and two-stroke oil. It is important to accurately
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 drastically affect the
ratio of the mixture.
WARNING! Always ensure there is
!
adequate ventilation when handling fuel.
Petrol
CAUTION! Always use a good quality petrol/oil mixture (at
least 90 octane).
• The lowest recommended octane rating is 90. If you
run the engine on a petrol with a lower octane rating
than 90 this can cause knocking. This leads to an
increased engine temperature, which can result in
serious engine damage.
• When working at continuous high revs a higher octane
rating is recommended. Use good quality unleaded petrol.
Two-stroke oil
• For best results and performance use HUSQVARNA
two-stroke oil, which is specially formulated for our
two-stroke engines. Mixture 1:50 (2%).
• If HUSQVARNA two-stroke oil is not available, you
may use another two-stroke oil of good quality that is
intended for air cooled engines. Contact your dealer
when selecting an oil. Mixing ratio 1:33 (3%).
• Never use two-stroke oil intended for water-cooled
outboard engines, sometimes referred to as outboard oil.
• Never use oil intended for four-stroke engines.

used. Then add the entire amount of oil. Mix (shake) the
fuel mixture. Add the remaining amount of petrol.
