5.1.3 Mixing fuel
The engine will suffer damage if run with fuel mixed in the wrong ratio or with unsuitable oil.
Use a mixing ratio of 1:50. This corresponds to 1 part good-quality two-stroke oil that complies with
the API-TC specification and 50 parts gasoline (e.g. 100 ml oil and 5 liters of gasoline mixed in a
suitable canister).
1. Pour the required quantity of two-stroke oil into the fuel canister.
2. Then fill the gasoline into the fuel canister.
3. Close the fuel canister.
4. Mix the fuel by shaking the fuel container.
If the quality of the two-stroke oil or the gasoline is unknown, then increase the mixing ratio to 1:25.
5.1.4 Filling the fuel tank
1. Mix the fuel (two-stroke oil / gasoline mixture) by shaking the fuel container.
2. Place the product in a steady upright position.
3. Open the fuel tank by turning the cap counterclockwise and then removing the cap.
4. Fill the tank slowly using a funnel.
5. Close the fuel tank by fitting the cap and then turning it clockwise.
