E-switch Protection™
The ON/OFF trigger switch has a no-volt release function.
In the event of a power outage or other unexpected shut
down, the trigger switch will need to be cycled (turned on
and off) to restart tool.
E-Clutch™
This unit is equipped with an E-Clutch™ (Electronic Clutch),
which in the event of a high-load or wheel pinch, the
unit will be shut off to reduce the reaction torque to the
user. The switch needs to be cycled (turned on and off) to
restart tool.
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 needs to be cycled (turned
on and off) 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.
Electronic Soft Start
This feature limits the initial start up momentum, allowing
the speed to build up gradually over a 1 second period.

ASSEMBLY AND ADJUSTMENTS


WARNING: To reduce the risk of serious personal
injury, turn unit off and disconnect it from
power source before making any adjustments or
removing/installing attachments or accessories.

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 center.
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.
