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.
No-Volt
The No-volt function stops the grinder restarting without the
switch being cycled if there is a break in the power supply.
Electronic Clutch
The electronic torque limiting clutch reduces the maximum
torque reaction transmitted to the operator in case of jamming
of a disc. This feature also prevents the gearing and electric
motor from stalling. The torque limiting clutch has been factory-
set and cannot be adjusted.

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. 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 Accessories Chart to select the proper guard /
accessory combination.
