FUEL HANDLING
WARNING!
Allow adequate ventilation while
handling fuel.
!
Two-stroke oil
• For the best performance, use HUSQVARNA
two-stroke oil, which has been specially
developed for Husqvarna two-stroke engines.
Mixing ratio: 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 marine outboard motors, so-called
outboard oil.
• Never use oil intended for four-stroke engines.
NOTE!
The machine is fitted with a two-stroke engine and
must always be run on a mixture of petrol and two-
stroke oil. It is important to measure the quantity of
oil accurately, to ensure the correct mixture ratio.
Small discrepancies in the amount of oil have a
great bearing on the proportions of the fuel mixture
when mixing small amounts of fuel.
Fuel
Petrol
NOTE!
Always use an oil-mixed quality petrol (at least
90 octane). If your machine is equipped with a
catalytic converter,
(see “technical data”) an
unleaded, oil mixed quality petrol should always
be used. A leaded petrol will destroy the
catalytic converter.
• The lowest recommended octane rating is 90. If
you run the engine on a petrol with a lower
octane rating than 90 so-called “knocking“ can
occur. This leads to an increased engine
temperature, which can result in a serious
engine breakdown.
• When working at continuous high revs a higher
octane rating is recommended.
