Inspect star dressers for loose shafts and worn discs
Round off the wheel edges with a hand stone before and after dressing to prevent the edges from
chipping
Use the work rest to support and guide the tool
Use a tool holder if one is available
Always apply pressure slowly and evenly
Always apply diamond dressers at the centre of the wheel or slightly below the centre, never above
Servicing
