For DEWALT tools equipped with the DEWALT E-Clutch system, it is a feature that senses the motion of the tool and reduces the motor torque to a manageable level if necessary. The E-Clutch indicator located on the top of the tool will illuminate to indicate status.
In addition to the E-Clutch system some tools are equipped with a mechanical slip clutch. The clutch is active when the low speed (1) is selected. When the bit or cutter bites into the workpiece, the clutch will slip and a ratcheting sound will be heard. Release the trigger. Continued clutching of the tool will reduce the life of this feature.
