Electronic Speed and Impact Control
(fig. 1, 3)
D25601, D25602, D25603
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 (fig. 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 notash, take the
tool to an authorized D
EWALT repair center.
Service Indicator LEDs (fig. 3)
D25601, D25602, D25603
The yellow brushwear indicator LED (s) lights up
when the carbon brushes are nearly wo
rn 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
ash if there is a fault with the tool or the brushes
have completely worn out (refer to Brushes under
Maintenance ).
Fully Vibration-dampened Main
Handle (fig. 1)
D25601, D25602, D25603
The dampers in the side handle (c) absorb the
vibrations transmitted to the user. This improves user
comfort during the operation.
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.
If the supply cord is damaged, it must be replaced
by a specially prepared cord available through the
D
EWALT service organisation.
Using an Extension Cable
An extension cord should not be used unless
absolutely necessary. Use an approved extension
cable suitable for the power input of this tool
(see technical data). The minimum conductor size is
1 mm
2
; the maximum length is 30 m.
When using a cable reel, always unwind the cable
completely.
ASSEMBLY AND ADJUSTMENTS
WARNING: To reduce the risk of
injury, turn unit off and disconnect
machine from power source before
installing and removing accessories,
before adjusting or changing set-
ups or when making repairs. Be sure
the trigger switch is in the OFF position.
An accidental start-up can cause injury.
WARNING: Tool bits may be hot and
gloves should be worn when changing
or removing them to avoid personal
injury.
