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 (Fig. D)
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.

Active Vibration Control
For best vibration control, hold the tool as described in Proper
Hand Position.
The active vibration control neutralises rebound vibration from
the hammer mechanism. Lowering hand and arm vibration,
it allows more comfortable use for longer periods of time and
extends the life of the unit.
The hammer only needs enough pressure to engage the active
vibration control. Applying too much pressure will not make
the tool drill or chip faster and active vibration control will
not engage.

injury, turn tool off and disconnect battery pack
