4. Fluid Drain Valves: Ensure the drain valves for both cleaning and testing fluids are securely installed and closed before adding any liquids.
5. Install Cleaning Bracket: Insert the stainless steel cleaning bracket into the ultrasonic cleaner tank.
6. Connect Pulse Signal Cable: Connect the main pulse signal cable to the designated port on the machine.
7. Install Fuel Distributor: Secure the 6-cylinder fuel distributor package onto the main unit.

6. Operating Instructions

6.1. Ultrasonic Cleaning

1. Prepare Injectors: Clean the exterior of the injectors with gasoline or a suitable cleaning liquid to remove loose dirt.
2. Place in Ultrasonic Cleaner: Place the fuel injectors into the ultrasonic cleaner tank, ensuring they are properly seated in the cleaning bracket.
3. Connect Pulse Signal: Connect the pulse signal wires from the main unit to each injector.
4. Add Cleaning Fluid: Pour professional injector ultrasonic cleaning fluid into the tank, ensuring the injectors are submerged. (Refer to "Fluid Selection" below).
5. Start Cleaning: Select the ultrasonic cleaning function on the control panel and press "Run" to start the cleaning process. The ultrasonic vibrations will dislodge carbon deposits.
6. Drain Fluid: After cleaning, drain the used cleaning fluid into a suitable container.

6.2. Fuel Injector Testing

1. Install Injectors: Securely install the cleaned fuel injectors onto the fuel distributor rail. Use appropriate adaptors and fix them with bolts.
2. Add Test Fluid: Pour professional injector test fluid into the main unit's reservoir. Ensure the fluid level is between MIN and MAX indicators. (Refer to "Fluid Selection" below).
3. Connect Pulse Signal: Connect the pulse signal wires from the main unit to each injector.
4. Select Test Function: Use the control panel to select the desired test function (e.g., Uniformity/Sprayability, Leakage, Injecting Flow, Auto Test).
5. Adjust Parameters: Set parameters such as RPM, PW (pulse width), and Timer (sec) as required for the specific test.
6. Monitor Pressure: Observe the system pressure gauge and adjust using the "Increase Pressure" or "Decrease Pressure" buttons if necessary.
7. Start Test: Press "Run" to begin the test. Observe the spray pattern, leakage, and flow rate in the graduated cylinders.
8. Evaluate Results: Compare the results against manufacturer specifications or expected performance.
9. Drain Fluid: After testing, drain the test fluid into a suitable container for recycling or disposal.

6.3. On-Vehicle Cleaning

The unit supports on-vehicle cleaning. This process involves connecting the machine to the vehicle's fuel system using specialized adaptors and couplers to clean injectors without removal. Consult your vehicle's service manual for specific on-vehicle cleaning procedures and compatible adaptors.

6.4. Fluid Selection

• Test Fluid: Used to evaluate injector performance. It should be a colorless, transparent liquid with no irritating odor, non-corrosive, and not easily evaporative. Professional automotive injector test fluids are recommended. As an alternative, medical alcohol with over 75% alcohol content can be used if professional fluid is unavailable locally.
• Cleaning Fluid: Used to remove deposits like carbon from injectors. It is typically highly corrosive and flammable. Professional injector ultrasonic cleaning fluid is recommended. Medical alcohol (over 75%) can be used as an alternative, but its effectiveness may be reduced compared to specialized cleaning fluids.
• Note: Cleaning and testing fluids are NOT included in the package and must be purchased separately from your local market.

7. Maintenance

• Regular Cleaning: After each use, clean the control panel and exterior of the machine with a soft, damp cloth.
• Fluid Management: Always drain and properly dispose of or store used cleaning and testing fluids. Do not mix different types of fluids unless specified.
• Storage: Store the machine in a dry, clean environment away from direct sunlight and extreme temperatures.
• Component Inspection: Periodically inspect all cables, hoses, and adaptors for wear or damage. Replace any damaged parts immediately.
