CAUTIONS

Warning
A Before using the instrument, please read this manual careful- ly for proper operation.

• 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 company 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.
• he 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.

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

Ultrasonic Cleaning

• 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 Cleaning” , 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.

• 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.

**Top-in fuel injector installation diagram

**

• Select the top olio 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.

Methods And Steps

Idle Speed Test

• Confirm that the injector to be tested has been installed properly and the signal wire has been plugged in.
• Select “02 Idle Speed Test”.
• Press the function setting key to set the working time and pulse width.

• 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 impurities 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.
