u Keep to the lubricating oil pressure at the inlet.
u Keep to the lubricating oil temperature at the inlet.
u Refer to chapter Monitoring operation →44 for admissible values.
Gas, air and oil pipes
u After starting the engine, check all gas, air and oil pipes for leaks.
4.2.4 Checks when starting up the engine
If present:
u Measure speed, oil pressure and charging pressure at various engine performances.
u Measure the exhaust gas temperature before and after the turbine.
u Measure the air temperature before and after the compressor.
u Compare the measured values with the values of the acceptance report. Different operat-
ing conditions indicate a malfunction (see chapter Eliminating malfunctions →78).
Lubricants and pastes used during assembly can liquefy or vaporise and escape as oily fluids
during the initial hours of operation. Continual escape of an oily fluid indicates an oil leak. If
there is a leak, contact an ABB Turbocharging Service Station.
