Before you start
- Replacing the oil must take place when the engine has its operating temperature (but is stopped), so that the fluid can be pumped out easily. The oil temperature is then about 80 degrees Celsius, so watch out for burning the skin!
Procedure
- Replace the engine lubricant and the oil filter after every 100 hours of service or at least once a year.
- Run the engine to operating temperature (about 80 degrees Celsius) and then stop it.
- Remove the dipstick first, then insert the hose of the sump pump into the pipe of the dipstick.
- Extract the oil by quickly pushing down the grip of the sump pump and then pulling it slowly upwards.
- When all lubricating oil has been drained, replace the oil filter.
- Collect the used oil and bring it to the service station in accordance with the environmental directives.
