HTS518 Walnut Sand De-Carbon Cleaner

The AUTOOL HTS518 Walnut Blaster is an advanced car engine carbon deposition cleaning equipment designed to deeply remove carbon deposits from the engine. It helps address issues such as unstable idle speed, incomplete fuel combustion, and increased fuel consumption. The AUTOOL HTS518 Sand Blasting Machine is equipped with a powerful 1400W motor that provides strong suction. It uses non-harmful walnut shell abrasive for cleaning, and the integrated filter screen separates the carbon deposits from the walnut shell abrasive, ensuring the walnut shell abrasive can be reused. With the support of an external air compressor, the machine provides robust sandblasting effects, ensuring thorough cleaning of the intake manifold and valves, ultimately restoring the engine to optimal performance.

Working Principle

The Walnut Shell Sand Blaster uses high-pressure airflow to blast walnut shell abrasive into the engine intake pipelines. The high-speed rolling and impact of the abrasive particles within the enclosed pipes effectively remove carbon deposits from the intake valves and cylinder walls. During the cleaning process, the specialized recovery nozzle’s suction tube collects the walnut shell abrasive mixed with carbon deposits and channels it into the sand storage tank for reuse.

AUTOOL HTS518 Walnut Blasting Machine Features

Intake Manifold Cleaning: The sandblasting method is used to clean the engine’s intake manifold, effectively removing carbon deposits and ensuring thorough cleaning.

Intake/Exhaust Valve Cleaning: The valves are cleaned without disassembly, following the sandblasting sequence, thoroughly removing carbon deposits without damaging the engine.

Multiple Adapters: Equipped with 23 different adapters, it is compatible with a wide range of vehicle models, including BMW, Volkswagen, Mercedes-Benz, GM, Volvo, Nissan, and more.

External Air Source Design: The walnut blaster is powered by a robust 1400W high-performance motor, which uses an external air source to provide continuous power. This enhances the impact force of the walnut shell abrasive, ensuring thorough removal of carbon deposits from the engine pipes.

Built-in Dust Filter: The equipment performs spraying and recovery simultaneously. The filter separates the walnut shell abrasive from the carbon deposits, ensuring that the walnut shell abrasive can be reused, while preventing residual particles from damaging the exhaust system at high temperatures.

Integrated Design: The walnut shell abrasive is recycled within the equipment, and no manual recovery is required, saving time and effort.

User-Friendly: The rear storage box is designed to store adapters, and the telescopic rod offers three adjustable height levels. Equipped with swivel casters, the unit can rotate 360°, allowing technicians to easily move the equipment during maintenance.

Three-Year Warranty, Lifetime Maintenance: For damage caused by non-human factors, AUTOOL promises to resend parts for free within 3 years. If you have any problems, please contact us, and we will respond within 24 hours!

Operating Instructions

1. After unpacking, place the AUTOOL HTS518 Walnut Blaster in the workspace. Take out the walnut sand abrasive recovery suction pipe from the accessory storage box and attach it to the walnut sand abrasive suction pipe interface on the product.

2. Take out the walnut sand abrasive recovery hose elbow from the accessory storage box and attach it to the other end of the walnut sand abrasive suction pipe.

3. Take out the sandblasting nozzle tube from the accessory storage box and attach it to the sandblasting nozzle.

4. Insert the sandblasting nozzle into the round hole on the elbow of the walnut sand abrasive suction pipe.

5. Connect the quick connector of the external air source to the product’s air intake port.

6. Plug the power cable into the external power socket.

Preparatory Work

1. Open the locks on both sides of the AUTOOL HTS518 Walnut Shell Sand Blaster machine head cover, remove the cover, and take out the filter element. Then, take the walnut shell abrasive from the accessory storage box and pour it into the stainless steel tank (recommended to pour 3~5 kg of walnut shell abrasive). Reassemble the filter element and the machine head cover in sequence.

2. Take the safety goggles from the accessory storage box and wear them.

3. Remove the vehicle engine intake manifold, inspect the carbon deposits inside the cylinders and on the valves, and check whether the intake and exhaust valves are in a closed state.

4. Ensure that the sandblasting nozzle, walnut sand abrasive suction pipe elbow, and vehicle-specific adapter have been properly assembled according to their respective configurations.

Operating Procedure

1. Open the top cover of the AUTOOL HTS518 Sandblaster, pour in 3~5 kg of walnut shell abrasive, press the dust cover onto the walnut sand abrasive, and close the lid, ensuring a proper seal.

2. Connect the nozzle of the sandblasting nozzle to the recycling hose (there is a hole on the recycling hose).

3. Remove the engine intake manifold, ensuring that the intake pipe is in an operable state.

Insert the sandblasting nozzle into the intake pipe and rotate the crankshaft to close the intake valve.

4. Connect the air pump (not included) to the AUTOOL HTS518 Sandblaster, ensuring the air source is functioning properly.

5. Turn on the power switch, and the machine will enter working mode. Select the appropriate working mode (low speed or high speed) and choose the suitable speed based on the carbon deposit condition.

6. Start the cleaning process, cleaning each manifold for about 2 minutes. After finishing, stop the machine and check the cleaning effect.

7. After cleaning the carbon deposits, use the dust blow gun to expel the remaining walnut sand abrasive.

Tips

1. Air compressor configuration: air pressure up to 0.7mpa, 6bar or more air pressure.

2. The walnut shell abrasive size should be between 0.4~0.8 mm. Under normal conditions, walnut shell abrasive can be reused 5~10 times.
