- Always handle and store wheels in a careful manner.
- Visually inspect all wheels before mounting for possible damage.
- Make sure operating speed established for machine does not exceed wheel speed.
- Check mounting flanges for equal and correct diameter.
- Use mounting blotters when supplied with wheels.
- Be sure work rest is properly adjusted. (Center of wheel or above; no more than 1/8″ away from wheel.)
- Always use a safety guard covering at least one-half of the grinding wheel.
- Allow newly mounted wheels to run at operating speed, with guard in place, for at least one minute before grinding.
- Always wear safety glasses and appropriate eye and face protection when grinding.
- Turn off coolant before stopping wheel to avoid creating an out-of-balance condition.
- Don’t use a wheel that has been dropped.
- Don’t force a wheel onto the machine or alter the size of the mounting hole — if the wheel won’t fit the machine, get one that will.
- Don’t ever exceed maximum operating speed established for the wheel.
- Don’t use mounting flanges that are not clean, flat, and designed for the wheel being used.
- Don’t tighten the mounting nut excessively.
- Don’t grind on the side of the wheel. (See ANSI B7.1 for exceptions.)
- Don’t start the machine until the wheel guard is in place.
- Don’t jam work into the wheel.
- Don’t stand directly in front of a grinding wheel when a grinder is started.
- Don’t grind material for which the wheel is not designed
These rules are designed as a guide for the individual user of grinding wheels whether he be in the employ of a large corporation or in the confines of his home workshop. It is based on the premise that grinding is a safe operation when a few basic rules are followed. These rules are based on material contained in the American National Standards Institute Safety Requirements B7.1 — “Use, Care & Protection of Abrasive Wheels.” Follow them.
