V. Operation
Important reminder: Before any operation, choose the correct injector type for proper operating. Press the GDI key
with the indicator light ON for GDI injectors. For general top-feed or side-feed injectors, no need to press this
key.

5.1 Resistance Test

1)
Connect one end of the resistance measurement line to the interface on the right side of the device, and the other
end to the two electrodes of the fuel injector.
2)
Start the machine, and press the
3)
If needed, measure several times to confirm the measured value.
4)
After the measurement is completed, remove the fuel injector and the resistance measurement line.

5.2 Ultrasonic Cleaning

Injector Cleaner takes advantage of the penetrability and cavitation impact wave caused by ultrasonic wave traveling
through the medium to provide powerful cleaning on objects with complex shapes, cavities and pores, so that the
stubborn carbon deposits can be removed from the injectors.
Procedures
1)
Place the injector/pump which has gone through surface cleaning in the launder.
2)
Add enough injector detergent into ultrasonic cleaner so that the liquid level is about 20mm above the needle
valve of injectors / whole pump.
3)
Plug the pulse signal wire to injector / pump respectively.
4)
Select ultrasonic cleaning function and then set the time.
Press RUN key to start the procedure.
5)
6)
Turn on the ultrasonic cleaning switch on the left side of the machine.
7)
When the time is up, it will stop automatically as the beeper rings.
8)
Turn off the ultrasonic cleaning switch on the left side of the machine after cleaning procedure.
9)
Take the injector / pump out of the launder and wipe them with a dry soft cloth. Get ready for next operation.
Note:
1)
It is strictly forbidden to open the ultrasonic system under the circumstances that cleaning agent has not been added
into the ultrasonic cleaning pool. Otherwise, the ultrasonic equipment may be damaged easily.
2)
It is strictly prohibited to immerse the pulse signal line connector along with the injector into the ultrasonic pool
for cleaning. Otherwise, the pulse signal line connector can be damaged easily.
3)
ATTENTION: Make sure to turn off the ultrasonic cleaning switch on the left side of the machine after cleaning
procedure.

5.3 Uniformity/Sprayability Test

Uniformity test is to find out the difference of the injectors injecting at the same working condition. This test can
indicate the comprehensive influences on the injector caused by electrical nature, bore variation and clogging. Spray
ability test is to inspect the spraying performance by observing the injectors.
Installing and testing procedures for injectors
1)
Choose a proper adaptor according to the injector type and mount it to the fuel separator.
2)
Install the injectors in forward direction (Apply a little lubricating grease on the O-ring.)
3)
Install the fuel separator with injector onto the plate of the test tube.
4)
Connect the injector pulse signal wire.
5)
Before doing this test, drain the test liquid from the measuring cup if there is any.
6)
Select Uniformity/Sprayability test function, set corresponding parameters (consult the appendix for pressure
setting, consult vehicle manuals for other parameters as needed), and then press RUN key to start the test.
7)
When the test is completed, the equipment will auto stop with the ring of the buzzer.
Note:
1)
The system pressure can be adjusted by pressing + or – at testing.
key. The resistance value will be displayed on the screen.
