5 Preparations at the workplace
5.1 Fuel
The two-stroke engine runs on a mixture of gasoline and oil. The quality of the fuel mixture decisively
influences operation and life expectancy of the engine.
WARNING
Risk of injury. The inhalation of gasoline vapors and skin contact with gasoline may be hazardous to the
health.
▶ Avoid direct skin contact with gasoline. Wear protective gloves.
▶ If your clothing becomes soiled with gasoline, it is essential to change your clothing.
▶ Ensure that the workplace is well ventilated in order to avoid breathing in gasoline fumes.
▶ Use a fuel container that complies with the applicable regulations.
5.1.1 Gasoline
▶ Use regular or super gasoline with an octane rating of at least 89 ROZ.
The alcohol content (e.g. ethanol, methanol or others) of the fuel used must not exceed 10%,
otherwise the life expectancy of the engine will be greatly reduced.
5.1.2 Two-stroke oil
▶ Use good-quality two-stroke oil for air-cooled engines that meets at least the API TC specification.
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.
6. Close the fuel canister.
