FUEL HANDLING

Fuel mixture

CAUTION! The machine is equipped with

atwo--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.

WARNING: Always ensure there is adequate ventilation when handling fuel.

Gasoline

CAUTION! Always use high quality unleaded gasoline.

SThis engine is certified to operate on

unleaded gasoline.

SThe 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.

SWhen working at continuous high revs a higher octane rating is recommended.

Two-stroke oil

SFor great results and performance use HUSQVARNA two--stroke oil, which is specially formulated for our two--stroke

engines. Mixture 1:50 (2%).

STo 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%).

SNever use two--stroke oil intended for water--cooled outboard engines,

sometimes referred to as outboard oil.

SNever use oil intended for four--stroke engines.
