Accessories
It is important to choose the correct guards, backing
pads and flanges to use with grinder accessories. See
pages 7–8 for information on choosing the correct
accessories.
WARNING:
Accessories must be rated for at least the speed recommended on the
tool warning label. Wheels and other accessories running over rated accessory speed
may burst and cause injury. Threaded accessories must have a M14x2 hub. Every
unthreaded accessory must have a 22 mm (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 7–8 of this manual. Accessory ratings must be above
listed minimum wheel speed as shown on tool nameplate.
