AUTOOL HTS518 Walnut Blasting Machine for Intake Valve Cleaning

HTS518 brings together the core functions expected from professional walnut blasting equipment: intake-port adapter coverage, simultaneous spraying and recovery, dust-filter media management, intake carbon removal, workshop mobility, 1400W rated power for vacuum recovery, and multiple operating modes. HTS518 uses a closed-loop walnut shell blasting process: abrasive impact loosens carbon deposits while vacuum recovery collects media and residue. The full service also includes intake access, valve-position confirmation, inspection, residual-media recovery, reassembly, final leak checks, diagnostic scanning, and a functional vehicle check. Before operating HTS518, check the air source, walnut abrasive, cleaning target, intake-valve position, adapter seal, required personal protective equipment (PPE), and final residual-media inspection steps. Always follow the service procedure for the specific vehicle when it differs from general product guidance.
