- See to it that that no combustible
or flammable materials are nearby that could be ignited by sparks
from the grinder wheel.
- See to it that that a guard
covers the grinding wheel on bench-mounted machines.
- Place the grinder tool rest
one-eighth inch from the wheel and slightly above the center

full speed before stepping into the grinding position. Faulty
wheels usually break at the start of an operation.

clamp to hold small pieces.

across the face of wheel in a uniform manner. This will keep
the wheel sound.
- Do not grind non-ferrous

it. If the wheel rings, it is probably sound.
- Replace wheels that are
badly worn or cracked.
- Never use a wheel that has
been dropped or received a heavy blow, even if there is no apparent
- Before using a new wheel, let it run a few seconds at full speed
to make sure it is balanced.
