Safety Rules

In addition to the standard shop safety rules for the machine shop:

  • Do not make contact with the revolving cutter.
  • Place a wooden pad or suitable cover over the table surface to protect it from possible damage.
  • Use the buddy system when moving heavy attachments.
  • Do not attempt to tighten arbor nuts using machine power.
  • When installing or removing milling cutters, always hold them with a rag to prevent cutting your hands.
  • While setting up work, install the cutter last to avoid being cut.
  • Never adjust the workpiece or work mounting devices when the machine is operating
  • Chips should be removed from the workpiece with an appropriate rake and a brush.
  • Shut the machine off before making any adjustments or measurements.
  • When using cutting oil, prevent splashing by using appropriate splash guards. Cutting oil on the floor can cause a slippery condition that could result in operator injury.
