Engine Shutdown
During longer breaks in operation, the engine must be warmed up at least once every two weeks. This prevents
corrosion in the engine. If you expect the engine to remain unused for two months or more, it must be preserved:
Refer to the chapter Storage, page 70.
Before Engine Shutdown
Let the engine run at high idle (1500 or 1800rpm) for a
minimum of 5 minutes before the shutdown after
normal use. Normal use is defined as minimum 50%
load. After use with less than 50% load, high idle for
approximately 3 minutes is sufficient. This allows
engine temperature equalization and prevents boiling
once stopped and also allows the turbochargers to cool
down. This contributes to long, fault-free service life.
NOTICE! Do not turn off the main switch within 2
minutes after turning off the ignition. This is in order to
save engine data to the engine control unit.

1 Disengage the clutch, if possible.

WARNING!
Working with or approaching a running engine is a
safety risk. Watch out for rotating components and hot
surfaces.
