WARNING: Accessories must be rated for at least the speed recom- mended on the tool warning label. Wheels and other accessories running over rated accessory speed may burst and cause injury. Every unthreaded accessory must have a 7/8" arbor hole. If it does not, it may have been designed for a circular saw and should not be used. Use only the accessories shown on pages 50–51. Accessory ratings must be above listed minimum wheel speed as shown on tool nameplate.

Switches

CAUTION: Hold the side handle and body of the tool firmly to maintain control of the tool at start up and during use and until the wheel or accessory stops rotating. Make sure the wheel has come to a complete stop before laying the tool down.

NOTE: To reduce unexpected tool movement, do not switch the tool on or off while under load conditions. Allow the grinder to run up to full speed before touching the work surface. Lift the tool from the surface before turning the tool off. Allow the tool to stop rotating before putting it down.
