Overload Clutch
In case of jamming of a drill bit, the drive to the drill spindle is
interrupted. Because of the resulting forces, always hold the
tool with both hands and take a firm stance. After the overload,
release and depress the trigger to re-engage drive.
Mechanical clutch
These tools are fitted with a mechanical clutch. The indication
that the clutch has activated will be an audible ratcheting
together with increased vibration.
Anti-Rotation System
In addition to the clutch, an anti-rotation system offers increased
user comfort 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.
The anti-rotation system indicator
indicate status.
