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.
Rotation Control System
In addition to the clutch, an anti-rotation system 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
reduced instantly. This feature prevents self rotation of the tool
reducing the occurrence of wrist injuries.
The anti-rotation system indicator
indicate status.
Anti-Rotation and Service Indicator LED (Fig. A)
