Operation Introduction WARNING: Read and understand the safety chapter before you use the product. Fuel This product has a two-stroke engine. CAUTION: Incorrect type of fuel can result in engine damage. Use a mixture of gasoline and two-stroke oil. Premixed fuel • Use Husqvarna premixed alkylate fuel of a good quality, for best performance and extension of the engine life.
