cooled two-stroke engines.
Mix the oil for two-stroke engines
according to the instructions on the
container, Petrol: Oil 40:1.
Petrol
&Danger
Under certain conditions petrol is
extremely flammable and explosive.
- Refuel only in a well ventilated area
and with the engine switched off.
Do not smoke and switch off all
ignition sources in the vicinity of the

- Do not overfill the fuel tank (there
must be no fuel in the inlet nozzle).
After filling up the petrol tank,
ensure that the tank cap is closed
and secured.
