7.3 Cleaning instructions for CRI/CRIN,
CRI Piezo and DHK/UI
!
Do not clean the nozzle cone with a brass brush,
steel brush or the like as this would damage the in-
jection orifices. Do not clean injection orifices with
the nozzle cleaning tool 0 986 611 140. Do not clean
the electrical connection of the injector with cold
cleaning agent.
1. Seal the inlet connection, return connection and
nozzle cone of the injector/nozzle holder with pro-
tective caps or cover over.
2. Use a plastic brush to remove any coarse dirt on the
injector/nozzle holder.
3. Pre-clean the injector/nozzle holder with cold clean-
ing agent.
!
Use the cleaning agent Tickopur TR 13 or a compa-
rable corrosion and coke-dissolving cleaning agent
for ultrasonic cleaning.
4. Remove the protective cap from the nozzle cone.
5. Attach the injector/nozzle holder to a suitable hold-
ing device and immerse it in the ultrasonic bath until
the nozzle retaining nut is completely covered by the
cleaning agent.
6. Set a cleaning temperature of 60°C to 70°C.
7. After approx. 15 minutes, take the injector/nozzle
holder out of the ultrasonic bath and blow dry with
compressed air.
i
After cleaning, always store injectors/nozzle holders
in a clean, closed container to prevent the injectors/
nozzle holders coming into contact with dirt par-
ticles (e.g. fluff, swarf).
i
