Match the adapter to the specific engine and intake-port shape before cleaning. The included adapter set fits multiple intake-port shapes, but it is not universal for every engine.<\/p>\n<\/article>\n<article class=\"autool-product-card\" data-feature-id=\"HTS678-KF02\">\n<h3>Integrated Spray And Vacuum Recovery<\/h3>\n<p>HTS678 sprays walnut abrasive and recovers it by vacuum at the same time, helping reduce scattered media and manual cleanup during intake carbon cleaning.<\/p>\n<\/article>\n<article class=\"autool-product-card\" data-feature-id=\"HTS678-KF03\">\n<h3>Built-In Dust Filter + HEPA Filtration<\/h3>\n<p>The built-in dust filter and HEPA filtration help manage collected walnut abrasive, carbon residue, and fine particulate during recovery. Recovered abrasive should be reused only when the vehicle service procedure permits it and the media remains suitable for reuse.<\/p>\n<\/article>\n<article class=\"autool-product-card\" data-feature-id=\"HTS678-KF04\">\n<h3>Adjustable Pressure Control<\/h3>\n<p>The pressure regulating knob and pressure gauge help users monitor and adjust blasting pressure for different intake cleaning tasks. Use pressure settings that match the HTS678 instructions, walnut media, air source, and vehicle service procedure.<\/p>\n<\/article>\n<article class=\"autool-product-card\" data-feature-id=\"HTS678-KF05\">\n<h3>Controlled Intake Valve Carbon Cleaning<\/h3>\n<p>With adjustable pressure control, walnut-shell abrasive helps remove carbon buildup from the intake pipe and the backs of intake valves, leaving the cleaned intake path visibly cleaner. Results vary with airflow, vehicle condition, diagnosis, and the service performed.<\/p>\n<\/article>\n<article class=\"autool-product-card\" data-feature-id=\"HTS678-KF06\">\n<h3>Standard Mode \/ Expert Mode<\/h3>\n<p>Choose Standard Mode or Expert Mode based on your experience and the cleaning task. Follow the HTS678 operating instructions when selecting Standard Mode or Expert Mode. Do not activate both modes at the same time.<\/p>\n<\/article>\n<article class=\"autool-product-card\" data-feature-id=\"HTS678-KF07\">\n<h3>Mobile Integrated Body<\/h3>\n<p>The three-section telescoping handle and 360\u00b0 swivel casters make the machine easier to move around the workshop, while the storage-box configuration helps keep accessories with the unit.<\/p>\n<\/article>\n<article class=\"autool-product-card\" data-feature-id=\"HTS678-KF08\">\n<h3>1500W Rated Power + External Air Source<\/h3>\n<p>HTS678 is rated at 1500W for the machine system and built-in recovery, while an external air compressor provides the blasting force for walnut-shell cleaning.<\/p>\n<\/article>\n<article class=\"autool-product-card\" data-feature-id=\"HTS678-KF09\">\n<h3>Walnut Media Recovery &amp; Reuse<\/h3>\n<p>The recovery and filtration system helps separate collected walnut-shell abrasive from carbon residue so suitable media can be reused. Under normal conditions, walnut-shell abrasive can be reused 5\u201310 times. Keep the media dry and replace it if it becomes contaminated, clumped, or cleaning performance drops.<\/p>\n<\/article>\n<article class=\"autool-product-card\" data-feature-id=\"HTS678-KF10\">\n<h3>3-Year Main Unit Warranty<\/h3>\n<p>Main unit: 3-year warranty.

external compressor, dry walnut abrasive, cleaning target, adapter seal, intake-valve position, selected operating mode, required personal protective equipment (PPE), and final residual-media recovery steps. Always follow the service procedure for the specific vehicle when it differs from general product guidance.<\/p>\n<\/header>\n<div aria-label=\"AUTOOL HTS678 safety and compatibility guidance\" class=\"autool-product-grid autool-product-grid--3 autool-product-rail\" data-autool-rail=\"safety-cards\">\n<article class=\"autool-product-card\">\n<h3>External Compressor Required<\/h3>\n<p>HTS678 requires an external high-pressure air compressor, which is not included. Use an external compressor with air pressure up to 0.7 MPa; 6 bar or more is generally recommended. Make sure it also provides sufficient continuous airflow and that the air tank, hose, quick-connect fittings, and duty cycle suit the blasting workflow.<\/p>\n<\/article>\n<article class=\"autool-product-card\">\n<h3>Use Dry Filtered Air<\/h3>\n<p>Use dry, filtered compressed air. Moisture may cause walnut abrasive to clump or feed inconsistently; a dryer\/water-separation setup is recommended.<\/p>\n<\/article>\n<article class=\"autool-product-card\">\n<h3>Compatible Walnut Abrasive<\/h3>\n<p>The recommended fill is generally 3\u20135 kg of 0.6\u20131.2 mm walnut abrasive. Follow the HTS678 operating instructions for loading and use. Walnut abrasive inclusion may vary by selected package option; check the selected package contents before ordering.<\/p>\n<\/article>\n<article class=\"autool-product-card\">\n<h3>Intake-Side Cleaning Scope<\/h3>\n<p>HTS678 is designed for intake-pipe and back-of-intake-valve cleaning. It is not designed for injectors, throttle valves, cylinders, or combustion chambers.<\/p>\n<\/article>\n<article class=\"autool-product-card\">\n<h3>Adapter Match and Sealing<\/h3>\n<p>Confirm that one of the supplied 23 adapters fits the target intake port, seals securely, and clears surrounding components.<\/p>\n<\/article>\n<article class=\"autool-product-card\">\n<h3>Valve Closure And Port Isolation<\/h3>\n<p>Start blasting only after confirming that the target intake valve is fully closed. Clean one intake port at a time and isolate other intake openings as required by the service procedure for the specific vehicle.<\/p>\n<\/article>\n<article class=\"autool-product-card\">\n<h3>One Operating Mode At A Time<\/h3>\n<p>Use Standard Mode or Expert Mode according to the HTS678 operating instructions and the service procedure for the specific vehicle. Use only one operating mode at a time.<\/p>\n<\/article>\n<article class=\"autool-product-card\">\n<h3>Protective Equipment and Walnut-Media Safety<\/h3>\n<p>Walnut-shell media can create dust and may trigger allergies. Wear suitable eye and respiratory protection, provide ventilation, and follow the walnut-media supplier Safety Data Sheet (SDS).<\/p>\n<\/article>\n<article class=\"autool-product-card\">\n<h3>Walnut Abrasive Reuse<\/h3>\n<p>Reuse walnut abrasive only when the service procedure for the specific vehicle permits it and the recovered media remains suitable for reuse.<\/p>\n<\/article>\n<article class=\"autool-product-card\">\n<h3>Residual Media Must Be Recovered<\/h3>\n<p>Remove visible residual walnut abrasive before starting the engine instead of relying on it to burn away. Before starting the engine, vacuum out the remaining abrasive and inspect the cleaned area to make sure no visible media remains.<\/p>\n<\/article>\n<article class=\"autool-product-card\">\n<h3>Mechanical Cleaning and Chemical Cleaner Guidance<\/h3>\n<p>Use HTS678 to remove suitable intake deposits; results vary with deposit severity and engine condition.<\/p>\n<\/article>\n<\/div>\n<\/div>\n<\/section>\n<section class=\"autool-section autool-comparison\" data-autool-nav=\"Spec&amp;Comparison\" data-autool-surface=\"dark\" id=\"autool-comparison\">\n<div class=\"autool-layout-container autool-layout-container--wide\">\n<header class=\"autool-section-head\">\n<p class=\"autool-subhead\">Compare models<\/p>\n<h2 class=\"autool-title\">Compare AUTOOL Walnut Blaster Models<\/h2>\n<p class=\"autool-lead\">Use this table to compare key specifications and feature differences across the AUTOOL walnut blasting models.<\/p>\n<\/header>\n<div class=\"autool-model-compare\" data-autool-model-compare=\"\" data-current-model=\"hts678\"><button aria-controls=\"hts678-compare-model-picker\" aria-expanded=\"false\" aria-label=\"Open model comparison selector\" class=\"autool-model-compare__mobile-trigger\" data-compare-picker-open=\"\" type=\"button\"><span class=\"autool-model-compare__mobile-trigger-copy\"><strong>Compare models<\/strong><span data-compare-mobile-summary=\"\">Selected: HTS678<\/span><\/span><span class=\"autool-model-compare__mobile-trigger-count\" data-compare-mobile-count=\"\">1<\/span><\/button><button aria-label=\"Close model selector\" class=\"autool-model-compare__scrim\" data-compare-picker-close=\"\" tabindex=\"-1\" type=\"button\"><\/button><\/p>\n<div aria-labelledby=\"hts678-compare-picker-title\" class=\"autool-model-compare__selector\" id=\"hts678-compare-model-picker\" role=\"group\">\n<div class=\"autool-model-compare__selector-head\">\n<div class=\"autool-model-compare__selector-copy\">\n<h3 class=\"autool-model-compare__legend\" id=\"hts678-compare-picker-title\">Compare models<\/h3>\n<p class=\"autool-model-compare__instruction\">Choose one or more models.

External compressed air drives the abrasive across the target intake surface, while the recovery system collects spent media and loosened carbon. Use compatible 0.6\u20131.2 mm walnut abrasive, follow the media Safety Data Sheet (SDS), and wear appropriate personal protective equipment (PPE).<\/p>\n<\/div>\n<\/details>\n<details>\n<summary>Can HTS678 Remove Carbon Buildup on Intake Valves?<\/summary>\n<div class=\"autool-faq-answer\">\n<p>HTS678 is designed to remove carbon buildup from supported intake-valve and intake-port surfaces when inspection confirms deposits and the service procedure for the specific vehicle supports walnut blasting. Use the correct adapter, pressure setting, and recovery procedure for the specific engine.<\/p>\n<\/div>\n<\/details>\n<details>\n<summary>When Should Intake Carbon Deposits Be Cleaned?<\/summary>\n<div class=\"autool-faq-answer\">\n<p>Use mechanical cleaning when inspection confirms suitable intake deposits and the vehicle procedure permits it. Service timing and performance results vary with engine condition and deposit severity.<\/p>\n<\/div>\n<\/details>\n<details>\n<summary>What Air Compressor Does HTS678 Need?<\/summary>\n<div class=\"autool-faq-answer\">\n<p>Use an external compressor with air pressure up to 0.7 MPa; 6 bar or more is generally recommended. Also make sure the compressor provides sufficient continuous airflow and dry air, and that the air tank, hose, quick-connect fittings, and pressure settings suit the vehicle and workshop setup.<\/p>\n<\/div>\n<\/details>\n<details>\n<summary>Is The Air Compressor Included?<\/summary>\n<div class=\"autool-faq-answer\">\n<p>No. The external air compressor (high-pressure air source) is not included and must be prepared separately.<\/p>\n<\/div>\n<\/details>\n<details>\n<summary>Is Walnut Media Included in the Package?<\/summary>\n<div class=\"autool-faq-answer\">\n<p>Walnut media inclusion depends on the selected package option. Check the selected package contents before ordering.<\/p>\n<\/div>\n<\/details>\n<details>\n<summary>How Much Walnut Shell Abrasive Should I Add?<\/summary>\n<div class=\"autool-faq-answer\">\n<p>The recommended fill is generally 3\u20135 kg of 0.6\u20131.2 mm walnut abrasive for HTS678. Keep the walnut abrasive dry and follow the HTS678 operating instructions for loading and use.<\/p>\n<\/div>\n<\/details>\n<details>\n<summary>How Does HTS678 Clean Carbon From Intake Valves?<\/summary>\n<div class=\"autool-faq-answer\">\n<p>HTS678 cleans carbon from the backs of intake valves one port at a time using walnut blasting, adjustable pressure control, and integrated recovery. Before blasting, make sure the target intake valve is fully closed and isolate the other intake openings according to the service procedure for the specific vehicle.<\/p>\n<\/div>\n<\/details>\n<details>\n<summary>Can HTS678 Clean Injectors, Throttle Valves, Cylinders, Or Combustion Chambers?<\/summary>\n<div class=\"autool-faq-answer\">\n<p>No. HTS678 is designed for intake-pipe and back-of-intake-valve cleaning\u2014not injectors, throttle valves, cylinders, or combustion chambers. Use a tool and cleaning procedure specifically designed for those other cleaning tasks.<\/p>\n<\/div>\n<\/details>\n<details>\n<summary>Where Can I Compare HTS678 and HTS728?<\/summary>\n<div class=\"autool-faq-answer\">\n<p>Use the AUTOOL Walnut Blaster Model Comparison table above to compare HTS678 and HTS728 across rated power, capacity, adapters, pressure controls, operating modes, filtration, and combustion-chamber capability.<\/p>\n<\/div>\n<\/details>\n<details>\n<summary>Where Can I Compare HTS558, HTS559, HTS518, HTS678, and HTS728?<\/summary>\n<div class=\"autool-faq-answer\">\n<p>Use the AUTOOL Walnut Blaster Model Comparison table above to compare rated power, capacity, adapters, filters, modes, pressure controls, and combustion-chamber capability across HTS558, HTS559, HTS518, HTS678, and HTS728.<\/p>\n<\/div>\n<\/details>\n<details>\n<summary>What Should I Check Before Operation?<\/summary>\n<div class=\"autool-faq-answer\">\n<p>Before cleaning, inspect the machine and accessories, secure the recovery hose, make sure the adapter fits and seals correctly, inspect the filter, use the specified dry walnut abrasive, confirm the target intake valve is closed, connect dry filtered air, isolate other intake openings as required by the service procedure for the specific vehicle, and wear appropriate eye and respiratory protection.<\/p>\n<\/div>\n<\/details>\n<details>\n<summary>How Can I Prevent Walnut Abrasive Residue From Remaining in the Engine?<\/summary>\n<div class=\"autool-faq-answer\">\n<p>Keep recovery active during cleaning, then vacuum out remaining walnut abrasive and inspect the cleaned area before reassembly. Before engine startup, confirm the intake valve position, check that the adapter seal was correct, and make sure no visible residue remains.<\/p>\n<\/div>\n<\/details>\n<details>\n<summary>How Long Is The Warranty?<\/summary>\n<div class=\"autool-faq-answer\">\n<p>The main unit includes a 3-year warranty, standard accessories include a 1-year warranty, and lifetime maintenance support is available.
