BENCH GRINDER

What this tool is primarily used for:

The Bench Grinder is used for grinding the edges of flat metals, removing burrs from the ends tubing or rods, and minor shaping of some metal tools
 

ALWAYS WEAR APPROPRIATE PPE WHEN USING THIS MACHINE

SAFETY FOR THIS MACHINE:

  • DO NOT operate while under the influence of drugs, alcohol, or medication
  • SECURE any loose fitting jewelry or clothing, tie back long hair - they can get caught in moving parts
  • INSPECT the wheels for cracks or chips before use. A cracked wheel will disintegrate when operated
  • GUARD must be used at all times
  • EYE SHIELDS must be over work area
  • GRIND ONLY ON THE FACE OF THE WHEELS. Grinding on the side of the wheel weakens the wheel and may cause breakage
  • ALWAYS USE TOOL REST when working with this machine
  • DO NOT force metal into moving grinding wheel
  • DO NOT make any adjustments to tool rests or spark arrestors while grinder is "ON"
  • REMOVE any wrenches from the grinder before use if you make adjustments to the tool rest
  • NEVER grind soft metals (bronze, zinc, copper) on wheels designed for hard metal. The grinder is normally set up for grinding hard metals, i.e. steel. Soft metals can become incorporated within the wheel resin, causing overheating and subsequent wheel disintegration. If you need to grind soft metals, see the shop tech
  • TURN ON THE DUST COLLECTOR ATTACHED TO THIS MACHINE
  • REFER to instruction manual for further information (see Studio Technician)
