Power‑OFF™ Overload Protection
The power supply to the motor will be reduced in case of
motor overload. With continued motor overload, the tool will
shut off. The switch will need to be released then depressed
to restart tool. The tool will power off each time the current
load reaches the overload current value (motor burn‑up point).
If continued overload shutdowns occur, apply less force/
weight on the tool until the tool will function without the
overload engaging.
Soft Start Feature
The soft start feature allows a slow speed build‑up to avoid an
initial jerk when starting. This feature is particularly useful when
working in confined spaces.

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.
