Operation Process

Ultrasonic Cleaning

Ultrasonic cleaning uses penetrating and cavitation shock waves generated by ultrasonic waves in the medium to powerfully clean objects with complex shapes, cavities, and pores, completely removing stubborn carbon deposits from the fuel injector.

Preparation

• Remove the fuel injector from the vehicle and check its rubber seal for damage. Replace if damaged to avoid leakage during testing.
• Turn on the power using the power switch on the side of the main unit.
• Place the cleaning bracket from the accessories into the ultrasonic cleaning tank and position the wiped fuel injector in the bracket's positioning hole.

Methods And Steps

1. Add an appropriate amount of cleaning agent to the ultrasonic tank, ensuring it covers the bottom of the cleaning stand.
2. Insert the plugs of the drive wires into the injector sockets. Use an adapter cable for special fuel injectors.
3. Use the selection keys (up/down) to select "01 Ultrasonic Cleaning". Set the working time using the time adjustment keys (default is 10 minutes).
4. Press the Start button and turn on the ultrasonic cleaning switch on the side of the device to begin cleaning. Use the Pause button to suspend or the Stop button to exit.
5. The heating switch on the side of the equipment can be turned on during cleaning to improve the cleaning effect.
6. The working time counts down. The system stops automatically when it reaches 0.
7. Remove the fuel injector from the ultrasonic tank, wipe off any cleaning liquid with a soft cloth, and prepare for the next job.

NOTE: During cleaning, you may hear an intermittent vibrating sound (approx. 5 seconds) when holding the injector to your ear, indicating normal operation. Ultrasonic cleaning is strictly prohibited without cleaning agent in the tank to prevent equipment damage. Only use dedicated ultrasonic cleaning agents; other reagents may void the warranty.

Injector Diagnostic

This function tests the atomization, dripping, blockage, and fuel injection angle of fuel injectors, as well as the volume and balance of fuel injection at different speeds.

Preparation

• Ensure the oil drain handle is open. Use the provided funnel to add test liquid through the glass window, controlling the flow rate to prevent overflow.
• Install the fuel injector.
