Features
E-Switch Protection™
The ON/OFF paddle switch has a no-volt release function. In
the event of an unexpected shut down, the paddle switch
will need to be released then depressed to restart tool.
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 paddle switch will
need to be released then depressed to restart 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 paddle switch will need to be released then
depressed 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 paddle 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.
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
before making any adjustments or removing/
installing attachments or accessories. An
accidental start‑up can cause injury.
Attaching the Auxiliary Handle (Fig. D)

TIMES to maintain complete control of the tool.
Always make sure the handle is tight.
Screw the auxiliary handle
mounting holes of the gear case.
Rotating the Gear Case (Fig. E)
To improve user comfort, the gear case will rotate 90° for

tightly into one of the threaded
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 D
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.
CAUTION: BEFORE operating the tool, identify which
guard adjustment option your tool is set to.
