Ultrasonic Cleaning Operation:
1.Pour in the injector detergent and place the injectors in the ultrasonic cleaner tank.
2.Connect the pulse signal wire and select the ultrasonic cleaning function to start working.

Fuel Injector Testing Operation:
1. Pour in the test liquid,install the fuel injector is to the fuel dstributor and fix main unit body
2. Test if the injector is leaking or blocked under different functions.

How to choose test fluid?

The test fluid is used to test and judge whether the performance of the fuel injector is in good condition. It is a colorless and transparent liquid with no irritating odor, non-corrosive, and not easy to emit. Its function is to simulate various working states of the fuel injector as a medium. In order to achieve the best test effect, it is recommended to use professional automotive injector test fluids. If it is not available locally, as an alternative, it's recommended that medical alcohol with an alcohol content of more than 75% can be used instead of the test fluid.

How to choose cleaning fluid?

Cleaning fluid is used to clean deposits (such as carbon deposits) on fuel injectors, and it is usually highly corrosive and flammable. In order to achieve the best test effect, it is recommended to use professional injector ultrasonic cleaning fluid. If it is not available locally, it's recommended that medical alcohol with an alcohol content of more than 75% can be used instead of the cleaning fluid, but note that the effect may not good enough.

FAQ
1) The unit does not respond when the power is turned on.
Check the fuse on the lower right side of the unit and replace the fuse (5A) if it is damaged or broken.

2) Fuel distributor (rail) is leaking.
Check the o-ring and replace if damaged or broken. Do not tighten the adapter fitting too much,
otherwise, it may cause leakage.

3) When running, there is no working pressure.
When using a new machine for the first time, or if the machine has not been used for a long time, there may be no fuel
pressure. In this case, select the "first time use" function in the system functions, and then do the following:
a) Connect the test connector to the unit's fuel supply line and insert it into the fuel filler neck as shown in the illustration.
b) Then, run the first time use function.
c) When liquid comes out of the test connector, stop the operation. The device stops automatically after 30 seconds of operation.

4) There is no oil feed pressure, the buzzer sounds.
The machine has a lack of fuel warning function, when there is not enough fluid in the tank, the machine will beep, then
automatically shut down the fuel pump and injector nozzle, and return to the stop state. Add test fluid to the unit until the
buzzer stops beeping.

5) Completely emptying the test fluid from the glass tube requires pressing the Drain button several
times.
The solenoid valve will automatically stop after 15 seconds and will need to be emptied more times if more fluid is present.
Precautions
a) 1)Do not place anything on the control panel to prevent breaking the test measuring cup/glass panel.
b) 2) Do not disconnect the oil feed connection until the system pressure reaches "0" to prevent test fluid from spraying out.
c) 3) Always ensure that the unit is reliably earthed when in use.
d) 4) The device has a lack of oil alarm function. When the liquid level falls below the minimum line, the device will emit a warning
sound and at the same time automatically stop the oil pump and injector nozzle work. Until the test liquid is sufficient, the
equipment will be able to work normally.
e) 5) Clean the control panel in time, pulse signal line please ask stained test liquid, cleaning agent.

Arrangement after use
a) It need to do some job as below after use.
b) Press the "Drain" icon to drain the test fluid into the fuel tank.
c) Turn off and pull of the power plug.
d) Clean the machine with a soft cloth.
e) Drain the test fluid from the fuel tank into a container to avoid evaporation. If reuse, store the it in a safe place and dispose of it
according to the relevant regulations if it is too dirty
