19. When do I have to change the engine oil?

The oil has to be replaced after every 50 operating hours and the engine has to be switched off and the device should still be warm.
To this end, start the engine for a short while, if required.
Place a suitable collecting container with a volume of at least 1 litre under the oil drain plug (A).
First open the oil drain plug (A) and then the oil filler neck (B) and drain off the entire engine oil using a suitable hose or pipe.
Close the oil drain plug (A) again and fill 0.6 litres of fresh engine oil into the oil filler neck (B).
Afterwards, check the oil level using the oil dipstick (B) and adjust the oil level, if required.
