4 Putting into operation
Low-load operation
Possible damage to the engine due to low-load operation.
► Run the engine at idling speed or at high engine speed at over 20 %
engine load.
Possible consequences of low-load operation are:
• Increased engine oil consumption
• Engine contamination due to engine oil in exhaust system
• Blue smoke in exhaust gas
• Shorter particulate matter catalyst regeneration cycles (only in case of
Tier IV)
• Reduced engine-oil replacement intervals
Stopping the engine
Possible damage to the engine when it is stopped after running under high
load.
► Letting the engine run at idling speed before stopping it avoids engine
damage and increases the engine’s service life.
1. Let the engine run at idling speed for five minutes without any load.
2. Turn the starting key to “0” and remove it.
After stopping the engine, wait two minutes before disconnecting the
battery or actuating the battery master switch to avoid damage to the
control electronics.
