E-Clutch® and Indicator Light (Fig. D)
The E-Clutch® offers increased user comfort and safety
through an on-board anti-rotation technology capable of
detecting if the user loses control of the hammer. When
a jam is detected, the torque and speed are stopped
instantly. This feature prevents self rotation of the tool
reducing the occurrence of wrist injuries.
The red indicator LED lights up when the electronic
11
clutch is engaged in any mode except the chipping mode.

Under exposure to certain electromagnetic phenomena
