• Young children and the infirm. This appliance is not
intended for use by young children or infirm persons
withoutsupervision.
• This product is not intended for use by persons (including
children) suffering from diminished physical, sensory or

unless they are supervised by a person responsible for their
safety. Children should never be left alone with thisproduct.
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 (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.
The anti-rotation system indicator
11
will illuminate to
indicatestatus.
Indicator Diagnosis Solution
OFF Tool is functioning
normally
Follow all warnings and instructions
when operating the tool.
SOLID Anti-Rotation
System has
been activated
(ENGAGED)
With the tool properly supported,
release trigger. The tool will function
normally when the trigger is depressed
again and the indicator light will go out
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.
