Product Overview<\/h2>\n

The AUTOOL HTS558 walnut blaster is a 1200W walnut sand de-carbon cleaner designed for intake pipe, intake manifold, and intake valve backside carbon deposit cleaning. It uses an external air compressor to drive walnut shell abrasive for physical blasting, while the built-in vacuum recovery and dust filter help separate carbon residue from reusable walnut media.<\/p>\n

Before You Order And Use<\/div>\n

Before You Order And Use<\/h2>\n

HTS558 needs walnut shell abrasive, an external air compressor, and correct intake valve preparation. Review the media size, compressor requirement, safety gear, and cleaning range before use.<\/p>\n <\/div>\n

\n
\n

External Air Compressor Required<\/h3>\n

The package does not include a high-pressure air pump or air compressor. Use an external compressor with sufficient pressure, generally 6bar or above. The original requirement also mentions up to about 0.7MPa.<\/p>\n <\/article>\n

\n

Walnut Sand Not Included<\/h3>\n

Walnut shell abrasive is not included in the package. Purchase suitable walnut media separately before cleaning.<\/p>\n <\/article>\n

\n

Use 0.6-1.2mm Media<\/h3>\n

Use walnut shell abrasive between 0.6-1.2mm for HTS558. Under normal conditions, the media can usually be reused 5-10 times.<\/p>\n <\/article>\n

\n

Dry Air Is Recommended<\/h3>\n

Use an air compressor equipped with a dryer filter when possible. Moisture can make walnut shell media clump and reduce blasting performance.<\/p>\n <\/article>\n

\n

Close Intake Valve First<\/h3>\n

Turn off the engine and rotate the crankshaft to close the intake valve before blasting. Clean one intake pipe or intake port at a time.<\/p>\n <\/article>\n

\n

Wear Safety Protection<\/h3>\n

Wear safety goggles and respiratory protection during operation to reduce risk from debris, dust, and fine walnut shell particles.<\/p>\n <\/article>\n <\/div>\n
