Hydraulic oil thermometer 10
Socket 11
It indicates hydraulic oil temperature during operation. High-
est admissible temperature is 90 °C (194 °F) for oil of viscosity
class of HV 68 and HV 100. Optimal operating temperature is
50 - 60 °C (122 - 140 °F).

HV 46 80 °C (176 °F)
HV 32 70 °C (158 °F)
Connection to ECM (Electronic Actuator Module) - actuator
units of the engine and diagnosing of defects or parameter ad-
justments
Note
ECM is designed to process data about engine function, and to
actuator its operation.
