Guards

WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect battery pack
before making any adjustments or removing/
installing attachments or accessories. An accidental
start-up can cause injury.

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