Guards

CAUTION: Guards must be used with all grinding
wheels, cutting wheels, sanding flap discs, wire
brushes, and wire wheels. The tool may be used
without a guard only when sanding with conventional
sanding discs. Refer to Figure A to see guards provided
with the unit. Some applications may require purchasing
the correct guard from your local dealer or authorized
servicecentre.
NOTE: Edge grinding and cutting can be performed with Type
27wheels designed and specified for this purpose; 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41wheel and a Type 1guard.
NOTE: See the Accessory Chart to select the proper guard /
accessorycombination.
