IMPORTANT INFORMATION ABOUT
GUARDS
Guards must be used with all grinding wheels, sanding flap discs, wire brushes and wire wheels. The tool may be used without a guard only when sanding with conventional sanding discs. DEWALT models D28493, D28494, D28474, D28499 are provided with a guard intended for use with depressed center wheels (Type 27), and hubbed grinding wheels (Type
27). The same guard is designed for use with sanding flap discs, 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.
CAUTION: DEWALT model D28497 Angle Sander may only be used for grinding by using appropriate accessory guard.
