• 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
mental abilities; lack of experience, knowledge or skills
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
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
15
will illuminate to
indicatestatus.
