Do not use the bench grinder if you have not been trained by one of the faculty.

• Always wear eye protection (safety glasses or a face shield).
• Tie back any loose clothing or hair. Remove rings, watch and other jewelry and roll up sleeves.
• Make sure the wheel guards are in place. Grinding creates heat; don’t touch any portion of the workpiece until you are sure it has cooled.
• Adjust the spark guards to be close to the wheel, and re-adjust these spark guards as the wheels wear down to a smaller diameter
• Stand to one side of the wheel when turning on power
• Tool rests should be adjusted close to the wheels and thoroughly tightened in place so they cannot shift position while in use
• Inspect the wheels before turning on the power. DO NOT use wheels that have been chipped or cracked.
• When grinding, use the face of the wheel only.
• DO NOT use a wheel that vibrates.
• Shut off the power and do not leave guards as the wheels wear down to a until the wheel has come to a complete stop and the work area is clean when finished using machine.
