AUTOOL HTS518 Walnut Sand De-Carbon Cleaner User Manual

1. Introduction

The AUTOOL HTS518 Walnut Sand De-Carbon Cleaner is an advanced automotive tool designed for efficient and non-destructive cleaning of carbon deposits in engine intake and exhaust pipes, and intake and exhaust valves. Carbon deposits, formed from incomplete combustion residues, can lead to various engine performance issues such as difficult cold starts, unstable idling, reduced power, slow acceleration, increased fuel consumption, and higher exhaust emissions. This machine utilizes walnut sand, a natural and harmless abrasive, to effectively remove these deposits, restoring optimal engine health and performance.

The HTS518 model is engineered for superior quality, featuring a high-quality motor for powerful suction and efficient carbon decomposition. Its design incorporates user-friendly features like a telescopic pull rod for easy mobility and a built-in dust filter for recycling walnut sand.

4. Setup Guide

Follow these steps to set up your AUTOOL HTS518 Walnut Sand De-Carbon Cleaner:

1. Prepare the Machine: Ensure the main unit is on a stable, level surface. The telescopic pull rod can be adjusted to three different heights for convenience.
   

   Figure 4.1: The telescopic rod allows for 3-stop height adjustment, making the unit easy to move and position.

2. Install Sand Suction Hose: Connect the sand suction hose to the designated port on the main unit. Ensure it is securely fastened to prevent leaks during operation.
3. Attach Sandblasting Gun and Adapters: Connect the sandblasting gun to the hose. Select the appropriate engine adapter from the provided set that matches the intake port of the vehicle you are working on. The kit includes 5 kinds of fittings suitable for various car models.
   

   Figure 4.2: The integrated design allows for simultaneous spraying and recovery of walnut sand, with various adapters to fit different engine types.
4. Connect External Air Source: The machine requires an external air compressor with an output pressure of 120PSI for optimal performance. Connect the air hose from your compressor to the machine's air inlet.
   

   Figure 4.3: The machine requires an external air source, typically an air compressor with 120PSI output pressure, to power the walnut sand blasting.

5. Load Walnut Media: Open the main unit and pour the walnut sand media into the designated compartment. Ensure the built-in dust filter is properly in place to separate recovered sand from carbon deposits for recycling.
   

   Figure 4.4: The built-in dust filter efficiently separates recovered walnut sand grit from carbon deposits, allowing for recycling of the media.

6. Power On: Plug the machine into a suitable power outlet (110V/220V, 50/60HZ).

5. Operating Instructions

Before operating, ensure you wear the provided safety goggles and any other necessary personal protective equipment.

1. Inspect Intake Valves: Before cleaning, visually inspect the engine's intake valves to assess the extent of carbon buildup. This helps in determining the required cleaning duration.

2. Select Speed Mode: The HTS518 features both low-speed and high-speed modes. For general cleaning, start with the low-speed mode. For stubborn or heavy carbon deposits, switch to high-speed mode for increased suction and blasting power.
3. Start De-Carbon Cleaning: Insert the sandblasting gun with the appropriate adapter into the engine's intake port. Activate the machine. The walnut sand will be blasted into the intake manifold, effectively removing carbon deposits. The integrated design ensures that the sand and dislodged carbon are simultaneously recovered by the machine's suction.

4. Monitor Progress: Continue the cleaning process until the carbon deposits are visibly removed. For most applications, complete cleaning can be achieved within three minutes per port.
5. Post-Cleaning Inspection: After cleaning, re-inspect the intake valves to ensure all carbon deposits have been removed. The valves should appear significantly cleaner.

6. Maintenance

Proper maintenance ensures the longevity and optimal performance of your AUTOOL HTS518:

• Filter Cleaning: Regularly check and clean the built-in dust filter. This filter separates the reusable walnut sand from the carbon deposits. A clogged filter can reduce suction efficiency.
• Walnut Sand Management: While walnut sand is organic and harmless, ensure proper disposal of used, contaminated sand. Reusable sand can be stored for future use.
• Hose and Gun Inspection: Periodically inspect all hoses and the sandblasting gun for any signs of wear, cracks, or blockages. Replace damaged components immediately.
• General Cleaning: Wipe down the exterior of the machine with a damp cloth after each use to remove any dust or residue.
• Storage: Store the machine in a dry, clean environment away from extreme temperatures and direct sunlight. Utilize the telescopic rod and universal pulleys for easy movement and storage.

7. Troubleshooting

If you encounter issues with your AUTOOL HTS518, refer to the following common troubleshooting tips:

• No Suction or Weak Suction:
  • Check if the power cord is securely plugged in and the machine is turned on.
  • Ensure the sand suction hose and all connections are tightly sealed.
  • Inspect the built-in dust filter for clogs and clean it if necessary.
  • Verify that the host capacity is not full.
• No Sand Blasting or Weak Blasting:
  • Confirm that the external air source (air compressor) is connected and providing sufficient pressure (120PSI).
  • Check if there is enough walnut media in the machine.
  • Inspect the sandblasting gun and hose for any blockages.
• Machine Not Turning On:
  • Ensure the power cable is properly connected to both the machine and the power outlet.
  • Check the power switch on the control panel.
  • Verify the power outlet is functional by testing with another device.
