Lubricating oil pressure

CAUTION
Assuring lubricating oil pressure
Serious damage to the engine or property can result from a missing or insuf-
ficient lubricating oil supply.
The lubricating oil pressure must be monitored during operation and the
u
necessary pressure assured at the oil inlet.
Fig. 13: Lubricating oil pressure measuring point
The measuring point M is at the oil supply channel of the high and low-pressure stage that is
not used for the oil supply.
