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

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

Confirm the abrasive, air compressor, cleaning range, intake valve position, and reuse rules before ordering or operating the walnut blaster.<\/p>\n <\/div>\n

\n
\n

External Air Compressor Required<\/h3>\n

HTS518 needs an external high-pressure air compressor for blasting. The air compressor is not included in the package.<\/p>\n <\/article>\n

\n

Use Dry Filtered Air<\/h3>\n

Use an air compressor with stable pressure and a dryer filter when possible. Moisture may cause walnut shell media to clump and reduce blasting performance.<\/p>\n <\/article>\n

\n

6 Bar Or Above Recommended<\/h3>\n

The original air compressor configuration calls for up to 0.7MPa and generally 6 bar or more. Always follow safe workshop and vehicle service limits.<\/p>\n <\/article>\n

\n

Walnut Sand Not Included<\/h3>\n

Walnut shell abrasive is not included. Prepare 0.6-1.2mm walnut abrasive before use, or purchase compatible walnut sand separately.<\/p>\n <\/article>\n

\n

Intake System Only<\/h3>\n

HTS518 is designed for the engine intake pipe and intake valve backside. It is not for injector, throttle valve, cylinder, or combustion chamber cleaning.<\/p>\n <\/article>\n

\n

Clean Port By Port<\/h3>\n

Close the intake valve before blasting. Clean one intake port each time; a 6-cylinder engine should be cleaned six times, one port at a time.<\/p>\n <\/article>\n <\/div>\n
