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
DCH243, DCH253, DCH254, DCH283
On units fitted with a mechanical clutch the indication that the
clutch has activated will be an audible ratcheting together with
increased vibration.
Electronic Clutch
DCH273, DCH274
When the electronic clutch activates, the motor is repeatedly
switched on and off for a few seconds to replicate the feedback
associated with a mechanical clutch.
Anti-Rotation System (Fig. E)
DCH283
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

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
vibraton control. Applying too much pressure will not make
the tool drill or chip faster and active vibration control will
not engage.
