Soft start feature
The soft start feature allows to build up speed slowly,
thus preventing the drill bit from walking off the
intended hole position when starting. The soft start
feature also reduces the immediate torque reaction
transmitted to the gearing and the operator if the
hammer is started with the drill bit in an existing hole.
Electronic speed and impact control
The electronic speed and impact control (3) offers
the following advantages:
– use of smaller accessories without risk of breakage
– minimised break-out when chiselling or drilling in
soft or brittle materials
– optimal tool control for precise chiselling
Torque limiting clutch
The torque limiting clutch 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.
D25701/D25730 - Complete torque control
The clutch torque can be switched between high
and low depending on the application. In normal
operation, the clutch is set in low torque which has
adequate torque for the majority of drilling applications.
If the bit jams in low torque, the clutch activates
much quicker than conventional hammer clutches.
8
Where low torque is not enough, the tool can be
switched into high torque providing a torque setting
similar to conventional machines. Every time the tool
is plugged in, the clutch will automatically reset to
low torque.
Service indicator LEDs
The yellow brushwear indicator LED (5) lights up
when the carbon brushes are nearly worn out to
indicate that the tool needs servicing within the next
8 hours of use. The red service indicator LED (4)
lights up if there is a fault with the tool or the brushes
have completely worn out.
Fully vibration-dampened main handle
The dampers in the main handle (13) absorb the
vibrations transmitted to the user. This improves
user comfort during the operation.
D25701/D25730 - Active vibration control
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.

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 D WALT tool is double insulated in
E
accordance with EN 60745; therefore no
earth wire is required.
