x
Ensure that no combustible or flammable materials are nearby that could be ignited by sparks from
the grinder wheel;
x
Ensure that a guard covers at least 270 degrees of the grinding wheel on bench-mounted machines;
x
Place the grinder tool rest 1/8 inch/20mm from the wheel and slightly above the centre line;
x
Allow the grinder to reach full speed before stepping into the grinding position. Faulty wheels usually
break at the start of an operation;
x
Unless otherwise designed, grind on the face of the wheel;
x
Use vice-grip pliers or clamp to hold small pieces;
x
Slowly move work pieces across the face of wheel in a uniform manner. This will keep the wheel
sound;
x
Do not grind non-ferrous materials;
x
Periodically check grinder wheels for soundness. Suspend the wheel on a string and tap it. If the
wheel rings, it is probably sound;
x
Replace wheels that are badly worn or cracked;
x
Never use a wheel that has been dropped or received a heavy blow, even if there is no apparent
damage;
x
Before using a new wheel, let it a run a few seconds at full speed to make sure it is balanced.

Never leave a chuck wrench in a chuck;

Never attempt to adjust a tool while the lathe is running;
