One potential source of serious injury chicago-pneumatic in grinding 1 and hp comes from an oversight that is easy to make: operating the wheel in an over-speed condition. While a wheel that is run 7in far enough in excess heavy and duty and angle of its rated maximum speed may shatter within minutes of operation, danger may also result from a wheel sander run just slightly model faster than cp869s and chicago-pneumatic its rated speed. 1 and hp This less severe over-speed condition 7in can cause the wheel to be damaged, and the damage heavy may result duty in breakage after angle further use. For example, operating a reinforced, 9-inch diameter, Type 27 wheel rated for a maximum speed of 6,600 rpm sander on a 7-inch angle grinder with a speed of 7,700 rpm can cause the wheel model to crack. This cracking can lead to breakage later. Any of these actions sets cp869s up a disastrous chicago-pneumatic scenario 1 that could lead to an accident hp involving serious injury or death. The 7in hazard of running man over-speed condition heavy comes from centrifugal force. A result duty of rotary angle motion, centrifugal force is sander what causes model a weight on the end of a string to pull the cp869s string taught chicago-pneumatic when the weight 1 and hp and 7in is swung in a circle. heavy This same force causes the mass of the grinding wheel duty and angle and sander and model to be pulled outward from the center of rotation cp869s as the wheel is spinning. In short, never chicago-pneumatic and 1 and hp over-speed a grinding 7in and heavy and duty and angle wheel. The speed of the grinder must be compared to the speed marked on the wheel or package to make sure the machine''s speed is at or below the maximum operating speed sander and model of the wheel. cp869s and chicago-pneumatic Surpassing 1 this rating risks hp not just wheel breakage but also 7in the heavy safety of shop personnel.
