Remove contamination manually with a soft brush or wire brush.

CAUTION
Water and contamination in the cartridge group
If water or contamination gets into the cartridge group, the turbochar-
ger function may be impaired and parts in the cartridge group may be
damaged.
Make sure that water or contamination does not get into the gap
u
between the sealing cover and turbine.
CAUTION
Non-permissible rotor unbalance after cleaning
Invisible and unevenly distributed residual contamination deposits lead
to rotor unbalance. This can result in bearing or turbocharger damage.
Remove all traces of contamination from the turbine.
u
After brushing off the contamination, fill the tank with clean water,
u
not salt water.
Submerge the turbine of the cartridge group in clean water, so that
u
loose particles of contamination detach completely.
Lift the cartridge group.
u
Dry turbine and gap between turbine and sealing cover with a weak
u
jet of compressed air.
Lightly spray turbine and gap between turbine and sealing cover with
u
penetrating oil.
Rotate cartridge group back to horizontal position (described proced-
u
ure in reverse order, see
end →57).
Dispose of contaminated water and cleaning agent in accordance
u
with the specifications in the safety data sheet.
