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 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 Grinding and Cutting Accessory Chart to
select the proper guard / accessory combination.
