INTENDED USE
D25501, D25601, D25602, D25603
Your rotary hammer has been designed for
professional rotary drilling and chipping applications.
D25831
Your chipping hammer has been designed for
professional chipping, chiselling and demolition
applications.
DO NOT use under wet conditions or in presence of
flammable liquids or gases.
These hammers are professional power tools.
DO NOT let children come into contact with the
tool. Supervision is required when inexperienced
operators use this tool.
Soft Start Feature
D25601, D25602, D25603, D25831
The soft start feature allows the speed 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
(fi g. 1, 3)
D25601, D25602, D25603, D25831
The electronic speed and impact control (g) 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.
Complete Torque Control (fi g. 3)
D25602, D25603
NOTICE: Always turn the tool off before
changing torque control settings or
damage to tool may result.
The Complete Torque Control (CTC) feature of this
tool is designed to provide additional control with a
two-stage clutch mechanism. Refer to Setting the
Torque Control Switch for more information.
Adaptive Drill Contol (ADC)
D25603 (FIG. 3)
The D25603 is equipped with an adaptive drill
control. This feature senses the motion of tool and
reduces the motor torque to a manageable level if
necessary. The red indicator LED (r) will illuminate to
indicate status.
NOTE: If tool power is insufficient for normal drilling
and the red LED indicator does not flash, take the
tool to an authorized D
WALT repair center.
E
Service Indicator LEDs (fi g. 3)
D25601, D25602, D25603, D25831
The yellow brushwear indicator LED (s) lights up
when the carbon brushes are nearly worn out to
indicate that the tool needs servicing within the next
8 hours of use.
D25601, D25602, D25603
The red service indicator LED (r) lights up if the
lock-on button (b) is used in any mode except the
chipping mode. In all models with the adaptive drill
control (ADC), the red indicator LED (r) lights up
if the ADC is engaged. The red indicator starts to
flash if there is a fault with the tool or the brushes
have completely worn out (refer to Brushes under
Maintenance).
D25831
The red service indicator LED (r) lights up if there is
a fault with the tool or the brushes have completely
worn out (refer to Brushes under Maintenance).
