Fuel and oil
Fuel
Use unleaded petrol with normal quality mixed with special 2-stroke motor oil for best results. Use the
mixing ratio stated in the section fuel mixing table further below.
Warning:
Never only use petrol for the device. This will lead to permanent motor damages and void the
manufacturer's warranty for this product. Never use a fuel mix, which has been stored for longer than
90 days.
Warning:
Only use top-quality 2-stroke lubricant/oil for air cooled 2-stroke motors mixed with a 1:30
ratio. Do not use 2-cycle oil product with a recommended mixing ratio of 1:100. If an insufficient lubrica-
tion is the reason for a motor damage, it will void the warranty of the manufacturer.

container to mix the two liquids thoroughly.
