5 Operation and service / 5.5 Stopping the engine
CAUTION
Manual switching of the flaps
If the gas inlet flap is opened during cut-out operation or the air-outlet flap
is closed during normal operation, this causes very high turbocharger
speeds. These can result in damage with serious consequences or even a
total loss of the turbocharger.
Never open the gas inlet flap during cut-out operation.
u
Never close the air-outlet flap during normal operation.
u
CAUTION
Automatic switching of the flaps
During automatic flap control, there is a risk of the turbocharger rotating
opposite the intended direction of rotation if the air-outlet flap is open fur-
ther than the gas inlet flap during the switching process. This can lead to
damage on the turbocharger.
The turbocharger should only be switched on or off below charging pres-
u
sures of 0.3 bar.
Close the compressor outlet flap just before the gas inlet flap.

NOTICE
Contamination with closed flaps
To limit the deposits of dirt when operating with closed flaps, we recom-
mend you open them at least every 500 hours of operation.
