Operation
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
ƔConnect the power supply: connect one end of the power cable to the power socket on ultrasonic
cleaner and the other end to power socket.
ƔPlace the injectors which have gone through surface cleaning in a launder.

ƔPlug the injector pulse signal wires to injectors respectively then turn on the power switch of the
ultrasonic cleaner.

Ɣ:KHQWKHWLPHLVXS,QMHFWRU&OHDQHU7HVWHUZLOOVWRSDXWRPDWLFDOO\
ƔTurn off the power of the ultrasonic cleaner, take the injectors out of the launder and wipe them with
a dry soft cloth. And they are ready for next operation.
Note:
ƔNever operation the ultrasonic cleaner when the tank’s empty, otherwise, damage may be incurred.
ƔDo not dip the pulse signal cables plug and the injector’s body into the detergent.
Uniformity/Spray-ability Test
Uniformity test is to find out if the flow of different injectors meets the requirement or specifications under
the same working condition. This test can reflect the comprehensive influences on the injector caused

On-Vehicle Cleaning
ƔPlease check if there is test liquid or detergent inside the fuel tank before on-vehicle cleaning. If
test liquid is in the tank, replace it with detergent. The detailed procedure to be followed: remove the
level indicator on the left of the main unit, and drain the test liquid inside fuel tank into a container. If the
drained test liquid contains lots of impurities and can not be reused, please dispose it in the proper way
and fill with new test liquid. If the drained test liquid is clean, please store it for later using.
