5. Safety Information

Always adhere to safety precautions when operating the CNC605A to prevent injury or damage to the equipment.

• Ensure the unit is placed on a stable, level surface in a well-ventilated area.
• Do not operate the unit near open flames or sources of ignition due to the presence of flammable liquids.
• Wear appropriate personal protective equipment (PPE), including safety glasses and chemical-resistant gloves, when handling cleaning fluids and fuel.
• Always disconnect the power supply before performing any maintenance or cleaning on the unit.
• Use only recommended cleaning and testing fluids. Refer to the fluid manufacturer's safety data sheets (SDS).
• Avoid direct contact with ultrasonic cleaning fluid and fuel. In case of contact, wash thoroughly with soap and water.
• Do not immerse the main unit in water or other liquids.
• Keep children and unauthorized personnel away from the operating area.

6. Setup and Installation

Follow these steps for initial setup of your CNC605A unit:

1. Unpacking: Carefully remove all components from the packaging. Verify that all items listed in Section 3.2 are present and undamaged.
2. Placement: Position the unit on a sturdy workbench in a well-ventilated workshop. Ensure there is adequate space around the unit for operation and maintenance.
3. Power Connection: Connect the provided power cable to the unit's power inlet (No. 12 in Image 3.1) and then to a grounded AC110V 50Hz power outlet.
4. Air Supply Connection: Connect an external air compressor (5-8 bar) to the air inlet pressure port (No. 9 in Image 3.1) using appropriate fittings.
5. Fluid Filling: Fill the ultrasonic cleaner tank (No. 4 in Image 3.1) with the recommended ultrasonic cleaning fluid. Fill the fuel tank (accessible via Fill port No. 8) with the appropriate testing fluid (e.g., calibration fluid or gasoline substitute). Note: Cleaning and testing liquids are not included and must be purchased separately.
6. Injector Installation: Install the desired fuel injectors into the fuel distributor (No. 2 in Image 3.1) using the appropriate adaptors and O-rings from the accessory kit. Ensure secure connections to prevent leaks.
7. Pulse Line Connection: Connect the pulse signal lines (No. 1 and No. 9/10) from the control board to each injector.

7. Operating Instructions

The CNC605A offers various modes for comprehensive injector testing and cleaning. Use the control board (No. 5 in Image 3.1) to navigate and select functions.

7.1 Ultrasonic Cleaning

1. Place the injectors into the ultrasonic cleaning tank.
2. Ensure the injectors are fully submerged in the ultrasonic cleaning fluid.
3. Select the 'Ultrasonic Cleaning' mode on the control panel.
4. Set the desired cleaning time (1-30 minutes).
5. Start the cleaning process. The ultrasonic waves will dislodge carbon deposits.

7.2 Uniformity and Sprayability Test

1. Install the injectors into the test tubes (No. 3 in Image 3.1).
2. Select 'Uniformity & Sprayability Test' mode.
3. Adjust parameters such as RPM and pulse width (PW) to simulate engine conditions.
4. Observe the spray pattern and volume in each glass tube. Look for consistent spray cones and equal fluid levels.

7.3 Sealing Test

1. With injectors installed in the test tubes, select 'Sealing Test' mode.
2. The system will apply a specific pressure.
3. Observe the injectors for any signs of leakage or dripping over a set period.

7.4 Injection Volume Test

1. Select 'Injection Volume Test' mode.
2. Set the duration for continuous spraying.
3. After the test, compare the fluid levels in the glass tubes to determine the injection volume of each injector.

7.5 No Disassembly Needed (EFI & SFI)

This function allows for on-vehicle cleaning of EFI and SFI injectors and the fuel supply system. Refer to the specific instructions for connecting the unit to the vehicle's fuel system without removing the injectors.

7.6 Automatic Mode

For streamlined testing, select 'Automatic Mode'. The unit will execute a preset program covering various tests. This mode is ideal for quick diagnostics and batch testing.
