Serious damage to engine or property can be caused by the overheating of
intact turbocharger components.
If the gas inlet is not blanked off, the lubricating oil supply remains switched
on (Further information for operation of 2-stroke engines, with blocked ro-
tor).
If there is a lubricating oil leak on the turbocharger, stop the oil supply.

and unbalance values if set screws (balancing screws) are loosened or un-
screwed on the compressor wheel.
Before recommissioning of the turbocharger, the compressor wheel must
be balanced at an ABB Turbocharging Service Station.
Do not screw any set screws that have become unscrewed into the com-
u
