| DO | DON’T |
| DO visually inspect all wheels before mounting for possible damage in transit. | DON’T use a wheel that has been dropped. |
| DO always handle and store wheels in a careful manner. | 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. |
| DO check maximum operating speed established for the wheel against machine speed. | DON’T ever exceed maximum operating speed established for the wheel. |
| DO check mounting flanges for equal and correct diameter. (Should be at least 1/3 diameter of the wheel and relieved around hole.) | DON’T use mounting flanges on which the bearing surfaces are not clean and flat. |
| DO use mounting blotters supplied with wheels. | DON’T tighten the mounting nut excessively. |
| DO be sure work rest is properly adjusted. (Center of the wheel or above; no more than 1/8″ away from the wheel.) | DON’T grind on the side of the wheel unless wheel is specifically designed for that purpose. |
| DO always use a guard covering at least one-half of the wheel. | DON’T start the machine until the wheel guard is in place. |
| DO allow newly mounted wheels to run at operating speed, with guard in place, for at least one minute before grinding or cutting. | DON’T jam work into the wheel. |
| DO always wear safety glasses or some type of eye protection when grinding or cutting. | DON’T stand directly in front of a grinding wheel whenever a grinder is started. |
| DO turn off coolant before stopping the wheel to avoid creating an out-of-balance condition. | DON’T grind or cut material for which the wheel is not designed. |
