5. Operating Instructions

5.1 Cleaning Functions

The CT500 offers three primary cleaning functions:

1. Ultrasonic Cleaning:

   This function uses ultrasonic waves to thoroughly remove carbon deposits and internal blockages from injectors. It can clean single or multiple injectors simultaneously.

   • Place injectors in the ultrasonic cleaning tank.
   • Add appropriate ultrasonic cleaning fluid to cover the injector tips.
   • Select "Ultrasonic Cleaning" on the display and set the desired cleaning time.
   • Start the cleaning process.

2. Reverse Flushing:

   This function cleans injectors by flowing fluid in the opposite direction of normal fuel flow. Note: Only 12V injectors are supported for reverse flushing. 70V and 120V injectors are not supported.

   • Install injectors in the opposite direction on the oil rail.
   • Select "Reverse Flushing" and initiate the process.
3. No-Disassembly Cleaning:

   This method allows for cleaning of the combustion chamber or throttle without disassembling the injectors. It requires connection to specific C100 special parts (sold separately).

   • Connect the machine to the C100 special parts as per the C100 manual.
   • Follow the instructions on the CT500 display to perform no-disassembly cleaning.

5.2 Testing Functions

The CT500 provides 12 comprehensive testing modes to evaluate injector performance:

• Idle Speed Test: Simulates engine idling conditions.
• Medium Speed Test: Simulates medium engine speeds.
• High Speed Test: Simulates high engine speeds.
• Accelerating Test: Evaluates injector response during acceleration.
• Variable Speed Test: Tests performance across a range of speeds.
• Leakage Test: Checks for fuel leaks from the injector.
• Idling Spray Value Test: Measures spray volume at idle.
• Medium Speed Spray Value Test: Measures spray volume at medium speed.
• High Speed Spray Value Test: Measures spray volume at high speed.
• Pulse Injection Test: Tests short pulse injection.
• Wide Pulse Injection Test: Tests longer pulse injection.
• Continuous Injection Test: Evaluates continuous fuel flow.

During testing, the machine assesses injection volume, uniformity of injection, atomization pattern, tightness, and dripping.

6. Maintenance

• Fluid Management: Regularly drain and replace cleaning and testing fluids to maintain optimal performance and prevent contamination. Use the oil drain handle for easy fluid removal.
• Cleaning: Wipe down the machine's exterior with a soft, damp cloth after each use. Avoid using abrasive cleaners or solvents.
• Injector Adapters: Clean injector adapters and connectors after each use to prevent residue buildup. Store them in the built-in storage drawer.
• Storage: Store the machine in a dry, clean environment when not in use.
