7 Periodic maintenance
7.1 Foreword to maintenance
Maintenance work includes regular visual controls and cleaning operations which are inten-
ded to ensure the trouble-free functioning of the low-pressure and high-pressure stage.
In this process, the exterior condition and the degree of contamination of the components
on which maintenance work is to be performed are determined.

Compressor cleaning
We recommend cleaning the HP compressor after the LP compressor.
On V-engines with several low-pressure and/or high-pressure stages per engine, Turbo Sys-
tems recommends the parallel cleaning of the LP compressors as well as the parallel clean-
ing of the HP compressors.
This cleaning process is faster and reduces the risk of surging of the low-pressure and high-
pressure stages.
