CAUTIONS
Warning
Since the test device is part of quartz glass, it is easy to break,
so do not place other objects around the equipment to avoid
bumping and breaking.
If there is no digital display after power on, please check
whether the power supply is powered; if so, check whether the
plug is connected firmly, or whether the fuse is blown. If it is not
broken, and the switch is still invalid after pressing the switch
several times intermittently, please contact the manufacturer
and must not disassemble it by yourself, otherwise our compa-
ny will not provide warranty.
When no cleaning agent is added to the ultrasonic tank, it is
strictly prohibited to open the ultrasonic cleaning item to avoid
damage to the ultrasonic system.
Every time the test solution is changed, it must be cleaned up,
and then 1L of new test solution should be added.
The use of unqualified testing agent will cause corrosion of the
oil pump, oil supply pipeline and failure of the pressure gauge.
Using other cleaning agent and testing agent will cause the
equipment surface coating to peel off.
It is strictly forbidden to use kerosene, gasoline or other testing
agent and cleaning agents as testing agent and cleaning
agents for this machine. Otherwise, the “O” ring and pipeline
rubber parts in the equipment will be damaged, causing
leakage.
The cleaning agent and testing agent should not be mixed up.
Before using the instrument, please read this manual careful-
ly for proper operation.

OPERATION PROCESS
Ultrasonic
cleaning
Ultrasonic cleaning is to use the penetrating and cavitation shock
waves generated when ultrasonic waves propagate in the medium,
and powerfully clean objects with complex shapes, cavities and
pores to completely remove stubborn carbon deposits on the fuel
injector.
Preparation
Remove the fuel injector from the vehicle and check whether
its rubber seal is damaged. If it is damaged, it should be
replaced in time before the cleaning test to avoid leakage
during the test. Then put the fuel injection nozzle into the
cleaning agent, carefully remove the external grease and wipe
it with a soft cloth.
Turn on the power and turn on the power switch on the side of
the main unit.
Put the cleaning bracket in the accessories into the ultrasonic
cleaning tank, and place the wiped fuel injector in the cleaning
bracket positioning hole of the ultrasonic tank.
●
●
●
Methods And Steps
Add an appropriate amount of cleaning agent to the ultrasonic
tank.
Insert the plugs of the drive wires into the injector sockets in
turn. (Special fuel injectors need to be connected with an
adapter cable)
Press the up or down key to select item 01 “Ultrasonic Clean-
ing” , and then press the function setting key to set the working
time.The default working time is 10 minutes, which can be
changed by up and down keys if needed.
Press START button, the system starts to feed pulse signal
and cleaning. After finishing cleaning, take out the injectors
from the ultrasonic bath, wipe the cleaning agent on them with
a soft cloth and prepare for the next item.

NOTE
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.
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.
Preparation
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.
Add 1 bottle (about 1000ml) of testing agent each time.
Install the fuel injector.

Select the top oil inlet connector from the accessories and
install it into the oil separator.
Install the fuel injector in the forward direction (apply a little
grease on the “O” ring of the fuel injector)
Put the horizontal end of the oil separator and the fuel injector
on the upper plate seat, and tighten the two ends with the
locking rod. Ready to test.

NOTE
Flow Balance Test
The flow balance test shall be carried out at different speeds.
When the liquid level in the measuring cylinder is 2/3 of the
measuring cylinder, pause or stop work to observe the balance
of the fuel injection volume. The deviation of the fuel injection
volume of all fuel injection nozzles on a vehicle should not
exceed 2%. Or refer to the relevant technical manual of the fuel
injector to judge the flow balance of the fuel injector.
Observation of Fuel Injection Shape
Observe whether the fuel injection shapes and angles of all
fuel injection nozzles on the same car are uniform at various
speeds. At the same time, you can adjust the opening pulse
width of the fuel injection nozzle to check whether the minimum
opening pulse width of the fuel injection nozzle is consistent.
Leak Detection Test
The leak detection test is to detect the tightness of the injector
needle valve under the high pressure of the system. (Observe
the tightness of the fuel injector, generally there should be no
leakage within one minute)

Reverse Flushing”, and install the injectors in the opposite
direction for cleaning.

STORAGE AND MAINTENANCE
Storage Turn off the power and unplug the power plug.
Put all connectors back into the accessory box for storage.
Drain the ultrasonic cleaning agent. Wipe the equipment clean
with a dry soft cloth.
If the machine needs to be stored for a long time, discharge the
testing agent into a bottle and seal it.
●
●
●
●
Replacement of Test Agent
When the test agent is used for a period of time, a lot of impuri-
ties will accumulate, and the agent containing dirt cannot be
used, otherwise it will easily block the fuel injector. When
replacing the agent, first open the testing agent drain valve to
empty the tank, and then inject a little testing agent to clean the
interior of the tank. After cleaning, drain the fuel tank again and
then pour 1L of new testing agent into the tank.
Fuse Replacement
There is a square box marked with a fuse on the power socket
on the left side of the device, and the fuse can be seen by
opening the box. If it is blown, replace it with a new one.
