Features
E-Switch Protection™
The ON/OFF slide switch has a no-volt release function. In
the event of an unexpected shut down, the unit will need
to be turned back on.
E-Clutch™
This unit is equipped with an E-Clutch™ (Electronic Clutch),
which in the event of a high-load, the unit will shut off to
reduce the reaction torque to the user. The slide switch will
need to be released then engaged to restart the tool.
Kickback Brake™
When a pinch, stall, or bind-up event is sensed, the
electronic brake engages with maximum force to quickly
stop the wheel, reduce the movement of the grinder,
and shut the grinder off. The slide switch will need to be
released then engaged to restart the 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 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 remove the battery pack

Rotating the Gear Case (Fig. E)
To improve user comfort, the gear case will rotate 90° for
cuttingoperations.
1. Remove the four corner screws attaching the gear case
to motorhousing.
2. Without separating the gear case from motor housing,
rotate the gear case head to desiredposition.

NOTE: If the gear case and motor housing become
separated by more than 1/8" (3.17 mm), the tool must
be serviced and re-assembled by a
DeWALT
service
center. Failure to have the tool serviced may motor and
bearingfailure.
3. Reinstall screws to attach the gear case to the motor
housing. Tighten screws to 12.5 in.-lbs. torque.
Overtightening could cause screws tostrip.
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.
Adjusting and Mounting Guard (Fig. F)

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.
One-touch
TM
: The engaging face is slanted and will ride
over to the next alignment hole when the guard is rotated
in a clockwise direction (spindle facing user) but self-locks in
the counter-clockwisedirection.
Mounting Guard (Fig. F)

CAUTION: Prior to mounting guard, ensure the screw,
lever, and spring are fitted correctly.
1. With the spindle facing the operator, press and hold the
