2) Insert the plugs of the drive wires into the injector sockets in turn. (Special fuel 
injectors need to be connected with an adapter cable)

3) Press the item selection up and down keys to select the "01 ultrasonic cleaning" 
item, and then press the working time up and down keys to set the time. (The 
system defaults to 10 minutes, if you need to modify the time, you can use the up 
and down keys to change)

4) Press the start button and turn on the ultrasonic cleaning switch on the side of 
the device to start cleaning. When working, you can press the pause button to 
suspend work or press the stop button to exit.

5) During the cleaning process, the heating switch on the side of the equipment can 
be turned on to improve the cleaning effect.

The working time gradually decreases. When it is 0, the system automatically 
stops.

Take out the fuel injection nozzle from the ultrasonic tank, wipe the cleaning liquid 
on it with a soft cloth, and prepare for the next job.

NOTICE

 

●  

During the cleaning process, you can hear the intermittent (approximately 5 

seconds) vibrating sound when you take the fuel injector out and put it to your ear, 
so you can judge whether the fuel injector is working normally.

●  

Ultrasonic cleaning is strictly prohibited when there is no cleaning agent in the 

ultrasonic tank to avoid equipment damage.

●  

Only the ultrasonic cleaning agent dedicated to cleaning the fuel injection 

nozzle can be added to the ultrasonic tank, and other reagents cannot be used 
instead, otherwise any malfunctions and damages caused will not be covered by 
the warranty.

3.2 Injector diagnostic

This function is to detect the atomization, dripping, blockage, fuel injection angle 
status of the fuel injectors and the size and balance of the fuel injection of each fuel 
injector at different speeds.

3.2.1 Preparation

1) Confirm that the oil drain handle is open, use the funnel in the 
accessories to 

add the test liquid to the equipment through the glass window, and pay

 

attention to control the flow rate during the addition to avoid overflow.

2) Add 1 bottle (about 1000ml) of testing agent each time.

3) Install the fuel injector.
