One potential chicagopneumatic6inorbitalpalmsandermodelcp7250sv source of serious injury in grinding comes from an oversight that is easy to make: operating the wheel in an over-speed chicagopneumatic6inorbitalpalmsandermodelcp7250sv condition. While a wheel chicagopneumatic6inorbitalpalmsandermodelcp7250sv that is run far enough in excess of its rated maximum speed may shatter within minutes of operation, danger may also result from a wheel run just slightly faster than its chicagopneumatic6inorbitalpalmsandermodelcp7250sv and chicagopneumatic6inorbitalpalmsandermodelcp7250sv rated speed. This less severe over-speed condition can cause the wheel to be damaged, and the damage may result in breakage after further use. For example, operating a reinforced, 9-inch diameter, Type 27 wheel rated for a maximum speed of 6,600 rpm on a 7-inch angle grinder with a speed of 7,700 rpm can cause the wheel to crack. This cracking can lead to breakage later. Any of these actions sets up a disastrous scenario that could lead to an accident involving serious injury or death.

In short, never over-speed a grinding chicagopneumatic6inorbitalpalmsandermodelcp7250sv wheel. The speed chicagopneumatic6inorbitalpalmsandermodelcp7250sv of the grinder must be compared to the speed marked on the wheel or package chicagopneumatic6inorbitalpalmsandermodelcp7250sv to make sure the machine''s speed is at or below the maximum operating speed of the wheel. Surpassing this rating chicagopneumatic6inorbitalpalmsandermodelcp7250sv risks not just wheel breakage but also the safety of shop personnel.
