The tool may be used without a guard only when sanding with conventional sanding discs. A Type 1 guard is available at extra cost from your local dealer or authorized service center. Grinding and cutting with wheels other than Type 27 and 29 require different accessory guards not included with tool. A Type 27 guard is provided for use with the Type 27 wheel. Mounting instructions for accessory guards are shown below and are also included in the accessory package.

MOUNTING AND REMOVING GUARD (FIG. 4, 5)
