List five rules that should be adhered to when using abrasive discs.
What will be an ideal response?
1. Do not use them on an aluminum head that uses an MLS gasket.
2. Do not use a disc of too coarse a grit. White bristle discs remove material more slowly than yellow ones, so they are safer to use.
3. Do not clean the "ghost marks" left when the gasket "stains" the aluminum head surface around water jacket openings. Attempting to do this will result in metal removal.
4. Be careful not to clean in one area longer than another.
5. Be certain that any material thrown about by the discs is carefully removed so it cannot ruin an engine.
