Wear a face shield over goggles for protection against heavy particles
Use a dressing tool approved for the job
Don't use a lathe cutting tool
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
Schedule regular servicing of grinders to keep them running safely. This includes:
Cleaning the entire machine and oiling all moving parts
Testing the motor, and replacing defective parts
