9 Starting and Stopping the Engine
► Make sure that the octane number of the gasoline is at 
least 90 RON and the ethanol content is not more than 
10%.
► Make sure the two-stroke engine oil you are using meets 
the requirements.
► Depending on the required amount of fuel, determine the 
correct amounts of two-stroke engine oil and gasoline in a 
mix ratio of 50:1. Examples for fuel mixes:
– 1 liter gasoline, 20 ml two-stroke engine oil
– 3 liters gasoline, 60 ml two-stroke engine oil
– 5 liters gasoline, 100 ml two-stroke engine oil
► Pour two-stroke engine oil into a clean approved fuel 
canister first and then add gasoline.
► Thoroughly mix the fuel.
8.2 Fueling the Trimmer
► Shut off the engine.
► Place your trimmer on a level surface so that the fuel tank 
cap faces up.
► Use a damp cloth to clean the tank cap and the area 
around it.
► Turn the tank cap counterclockwise until it can be 
removed.
► Remove the fuel tank cap.
NOTICE
Bright light, sunlight and extreme temperatures can cause 
the fuel mix to separate much faster. The trimmer can be 
damaged if it is used with a fuel mix that has become 
separated.
► Thoroughly mix the fuel.
► Do not use fuel mix that has been stored for more than 30 
days.
► Fill the tank to within no more than 15 mm of the brim, 
taking care not to spill any fuel.
► Fit the tank cap on the tank opening.
► Turn the tank cap clockwise and tighten it down firmly by 
hand.
The fuel tank is closed.
