The tool may be used without a guard only when sanding with conventional sanding discs. A Type 1 guard (intended for use with Type 1 cutting wheels and Type 27 wheels marked for cutting only) is available at extra cost from your local dealer or authorized service center. Grinding with wheels other than Type 27 and Type 29 require different accessory guards not included with the tool. A type 27 guard is provided for use with a 1/4" (6.35 mm) thick Type 27 wheel. NOTE: Edge grinding and cutting can be performed with Type 27 wheels designed and specified for this purpose; 1/4" (6.35 mm) thick wheels are designed for surface grinding while thinner Type 27 wheels need to be examined for the manufacturer's label to see if they can be used for surface grinding or only edge grinding/cutting. A Type 1 guard must be used for any wheel where surface grinding is forbidden. Cutting can also be performed by using a Type 1 wheel and a Type 1 guard.
