Troubleshooting

Compound feels dry on a small tool

Low surface speed and low temperature may prevent the compound binder from becoming mobile enough.

Symptoms

  • Compound feels dry, dusty or inactive on a small tool.
  • The tool does not transfer compound smoothly into the contact zone.

Likely causes

  • Low surface speed and low temperature may prevent the compound binder from becoming sufficiently mobile.
  • Too much compound or a dirty tool can make the small-tool contact even less stable.

Checks

  • Check tool diameter and rpm.
  • Inspect whether the tool is clean and lightly charged.
  • Compare behaviour with a standard wheel if possible.

Recommended fixes

  • Use less compound.
  • Clean the tool.
  • Check rpm and diameter.
  • Consider low-temperature LUXI compounds when the tool remains cool.

Prevention

  • Develop small-tool routes separately from standard wheel routes.
  • Record rpm, diameter and compound behaviour.
