FUEL HANDLING

Fuel

CAUTION! The machine is equipped with a two-stroke engine and must always been run using a mixture of gasoline and two-stroke engine 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.

 

 

 

 

 

Gasoline

CAUTION! Always use high grade unleaded oil mixed gasoline (minimum 87 RON). If your machine is equipped with a catalytic converter (see chapter on Technical data) always use a good quality unleaded petrol/oil mixture. Leaded petrol will destroy the catalytic converter and it will no longer serve its purpose.

Use low-emission gasoline, also known as alkylate gasoline, if it is available.

•This engine is certified to operate on unleaded gasoline.

•The lowest recommended octane rating is 87. If you run the engine on lower octane rating than 87 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.

Two-stroke oil

•For the best results and performance use JONSERED two-stroke oil, which is specially formulated for our two- stroke engines. Mixture 1:50 (2%).

•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.
