CAUTION
Machine damage
If the oil temperature at the oil inlet exceeds the admissible range, this
may lead to engine damage.
Observe oil temperature at the oil inlet according to the following table.

Lubricating oil temperature at the outlet
The oil temperature at the outlet is mainly dependant on:
Lubricating oil temperature and pressure at the oil inlet
Engine load and turbocharger speed
Exhaust gas temperature
The maximum admissible oil temperature at the outlet is listed in the fol-
lowing table. The specified oil outlet temperature is to be considered as
alarm value for the turbocharger operation and must be monitored accord-
ing to the current regulations.

If the turbocharger was operated for a longer period of time outside of the
admissible range, ABB Turbo Systems recommends to have the turbo-
charger inspected by an ABB Turbocharging Service Station.
