Leaktightness of pipes
WARNING
Risk of burning from hot gas
Escaping gases are hot and will lead to serious burns in the event of contact.
Check all pipes for leaks in accordance with the enginebuilder's instruc-
u
tions.
Wear safety gloves to protect against thermal hazards.
4.2.4 Checks when starting up the engine
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
The measured values must be compared with the values of the acceptance protocol; differ-
ent operating conditions must be taken into account here.
Escape of oily fluids
Lubricants and pastes used for the assembly of the low-pressure and high-pressure stage
can liquefy or vaporise and escape as oily fluids during the initial hours of operation. Con-
tinual escape of an oily fluid indicates a possible oil leak.
In the event of a leak, contact a Turbo Systems service station.
