Residual risks
• In spite of the application of the relevant
safety regulations and the implementation of
safety devices, certain residual risks cannot be
avoided.
These are:
– Impairment of hearing.
– Risk of dust inhalation.
– Risk of personal injury due to prolonged use.
– Risk of burns due to accessories becoming
hot during operation.
TORQUE LIMITING CLUTCH
All rotary hammer drills are equipped with a torque
limiting clutch that reduces the maximum torque
reaction transmitted to the operator in case of
jamming of a drill bit. This feature also prevents the
gearing and electric motor from stalling. The torque
limiting clutch has been factory-set and cannot be
adjusted.
Electrical safety
The electric motor has been designed for one
voltage only. Always check that the power supply
corresponds to the voltage on the rating plate.
Your DEWALT tool is double insulated in
accordance with EN 60745; therefore no
earth wire is required.
In case of cord replacement the tool must only be
repaired by an authorized service agent or by
qualified electrician.

If an extension cable is required, use an approved
extension cable suitable for the power input of this
tool (see technical data). The minimum conductor
size is 1.5 mm
