SAFETY INSTRUCTIONS
IMPROPER USE OF GRINDING WHEEL MAY CAUSE
BREAKAGE AND SERIOUS INJURY.
Grinding is a safe operation if the few basic rules listed below are followed. These rules are based on material
contained in the ANSI B7.1 Safety Code for "Use, Care and Protection of Abrasive Wheels". For your safety,
we suggest you benefit from the experience of others and follow these rules.
DO
1. DO always HANDLE AND STORE
wheels in a careful manner.
2. DO VISUALLY INSPECT all wheels before
mounting for possible damage.
3. DO CHECK MACHINE SPEED against the
established maximum safe operating speed
marked on wheel.
4. DO CHECK MOUNTING FLANGES for equal
and correct diameter.
5. DO USE MOUNTING BLOTTERS when
supplied with wheels.
6. DO be sure WORK REST is properly
adjusted.
7. DO always USE A SAFETY GUARD COVERING
at least one-half of the grinding wheel.
8. DO allow NEWLY MOUNTED WHEELS to run at
operating speed, with guard in place, for at least
one minute before grinding.
9. DO always WEAR SAFETY GLASSES or some
type of eye protection when grinding.
DON'T
1. DON'T use a whee that is cracked, HAS BEEN
DROPPED, or one that is damaged.
2. DON'T FORCE a wheel onto the machine OR
ALTER the size of the mounting hole--if wheel won't
fit the machine, get one that will.
3. DON'T ever EXCEED MAXIMUM OPERATING
SPEED established for the wheel.

surfaces ARE NOT CLEAN, FLAT AND FREE OF
BURRS.
5. DON'T TIGHTEN the mounting nut EXCESSIVELY.

grinding wheel whenever a grinder is started.
10. DON'T FORCE GRINDING so that motor slows
noticeably or work gets hot.
AVOID INHALATION OF DUST generated by grinding and cutting operations. Exposure
to dust may cause respiratory ailments. Use approved NIOSH or MSHA respirators, safety
glasses or face shields, and protective clothing. Provide adequate ventilation to eliminate
dust, or to maintain dust level below the Threshold Limit Value for nuisance dust as
classified by OSHA.
