the function of the turbocharger and damage parts inside the cartridge
group.
Make sure that no water or dirt enters the gap between the heat sheet
u
metal and the turbine.
CAUTION
Non-permissible rotor unbalance after cleaning
Unevenly distributed residual contamination deposits lead to rotor unbal-
ance. This can result in bearing or turbocharger damage.
Remove all traces of contamination from the turbine.
