7.5 Cleaning instructions for CRI/CRIN
and CRI Piezo xxx
!
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 with protective caps or
cover over.
2. Use a plastic brush to remove any coarse dirt on the
injector.
3. Pre-clean the injector with cold cleaning agent.
!
Use the cleaning agent Tickopur TR 13 or a compara-
ble corrosion and coke-dissolving cleaning agent for
ultrasonic cleaning.
4. Remove the protective cap from the nozzle cone.
5. Attach the injector to a suitable holding 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 min, take the injector out of the
ultrasonic bath and blow dry with compressed air.
i
After cleaning, always store injectors in a clean,
closed container. This prevents the injectors from
coming into contact with dirt particles (e.g. fluff and
swarf).
i
Also heed the additional cleaning information in the
ESI[tronic] 2.0 component repair instructions.

7.6 Connecting the CRI/CRIN and
CRI Piezo
WARNING – Risk of injury!
If the hydraulic connections for the testing
equipment and the injectors are not set up
properly, test oil can escape at high pres-
sure during the test or parts of the testing
equipment can burst. This can cause injury
or damage to property.
¶
Prior to switching on, check that all hose
assemblies have been properly connected
to the EPS 118 and the injector.
¶
Replace any leaking and defective hose
assemblies.
WARNING – Risk of hand injuries!
Uncontrolled closing of the protective hood
can lead to crushing or finger injury.
¶
Always close the protective hood using
the handle.
WARNING – Risk of burns from hot surfaces!
Contact with hot components and the hot
test equipment (e.g. injector) may cause
severe burns.
¶
Allow the components and test equipment
to cool down.
¶
Wear protective gloves.
DANGER – Risk of fatal injury from electro-
magnetic fields!
The high voltages at the piezo CRI (charging
of the actuators) and at the adapter cables
are a source of potential fatal injury for
persons wearing pace-makers are implanted
defibrillators.
¶
Piezo CRI testing may not be performed
by persons with pace-makers are implant-
ed defibrillators.
!
Do not check any damaged and/or severely corroded
components.
!
Use only for EPS 118 approved accessories. Using
accessories not intended for the EPS 118 can result
in incorrect measurements and thus a faulty evalua-
tion of the injector.
