To mix fuel Gasoline • Use good quality unleaded gasoline with a maximum of 10% ethanol contents. CAUTION: Do not use gasoline with an octane grade less than 90 RON/87 AKI. Use of a lower octane grade can cause engine knocking, which causes engine damages. • We recommend that you use gasoline of a higher octane grade for work with continuously high rpm. Two-stroke oil • For best results and performance use Husqvarna two-stroke oil. • If Husqvarna two-stroke oil is not available, use a two-stroke oil of good quality for air-cooled engines. Speak to your servicing dealer to select the correct oil. CAUTION: Do not use two-stroke oil for water-cooled outboard engines, also referred to as outboard oil. Do not use oil for four-stroke engines.

To do a run-in • During the first 10 hours of operation, do not apply full throttle without load for extended periods.
