The hazard of running man over-speed condition comes from centrifugal chicago-pneumatic force. A result of rotary motion, 1 centrifugal force is what causes a weight 2 on the hp end belt of a string to pull sander and model and cp858 the string taught when chicago-pneumatic the weight is swung in a circle. This same force causes the mass of the grinding wheel 1 to be pulled outward from the center of rotation as the wheel is spinning. One potential source of serious injury in grinding 2 comes from hp an oversight that is easy to belt make: operating the wheel in an over-speed sander and model condition. While a wheel that cp858 is run far enough in excess of chicago-pneumatic and 1 and 2 its rated maximum speed may shatter hp within minutes of operation, danger may also result from a wheel run just slightly faster than belt and sander its rated speed. This less severe model over-speed cp858 and chicago-pneumatic condition can cause the wheel to be damaged, and the damage may result in breakage 1 and 2 after further use. For example, hp operating a reinforced, 9-inch diameter, Type 27 wheel rated for a maximum belt speed of sander model and cp858 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 chicago-pneumatic over-speed a grinding wheel. The speed of the grinder must be compared to the speed marked 1 and 2 and hp and belt and sander on the model wheel or package to make sure the machine''s speed is cp858 at or below the maximum operating speed of the chicago-pneumatic wheel. Surpassing 1 this rating risks not 2 and hp and belt just sander wheel breakage but also the safety of shop personnel.
