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.
u
Never open the gas inlet flap during cut-out operation.
u
Never close the air-outlet flap during normal operation.
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.
u
The turbocharger should only be switched on or off below charging pres-
sures of 0.3 bar.
u
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.
