Features DWE43214, DWE43214N, DWE43214NVS, DWE43244N E-switch Protection™ The ON/OFF paddle switch has a no-volt release function. In the event of a power outage or other unexpected shut down, the paddle switch will need to be cycled (turned off and then on) to restart tool. E-Clutch™ This unit is equipped with an E-Clutch™ (Electronic Clutch), which in the event of a stall or wheel pinch, the unit will be shut off to reduce the reaction torque to the user. The switch needs to be cycled (turned off and then on) to restart tool. Brake When the paddle switch is released the motor immediately turns off and electronically brakes stopping the accessory quickly. Kickback Brake™ When a severe 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. Turn the unit on to restart tool. Constant Clutch™ When overloaded or stalled the motor torque is reduced. If load is reduced the torque and RPM will increase. If the tool is stalled for an extended amount of time it will shut-off and require the switch to cycle to restart.

The tool may be used without a guard only when sanding and surface finishing with conventional sanding and surface finishing diamond pads. 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; 1/4" (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.
