wire brushes and wire wheels. Grinding and cutting with wheels
other than Type 27 and 29 require different accessory guards not
included with the tool. Mounting instructions for these accessory
guards are included in the accessory package.
CAUTION: When using a grinding wheel with a Type 27, 28, or
29 guard, be sure that the bottom surface of the grinding wheel is
inside the the guard lip.
