4 Putting into operation
Low-load operation
The running behavior of the engine can be negatively affected if it runs at
idling speed or high speed and at less than 20% of the load.
► Run the engine in regular operation at loads of over 20 %.
Possible consequences of low-load operation are:
• Increased lube oil consumption.
• Lube oil in exhaust system, and therefore engine contamination.
• Blue smoke in exhaust gas.
Stopping the engine
Engine damage by stopping the engine after full load.
► In order to stabilize the temperature, let the engine run at idling speed
with no load for at least five minutes, and then shut it off.
Turn the starting key to “0” and remove it.
