Electronic Speed and Impact Control
(fig. 1, 3)
D25601
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.
Service Indicator LEDs (fig. 3)
D25601
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
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).
Fully Vibration-dampened Main
Handle (fig. 1)
D25601
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 IEC 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
DeWALT
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.
Assembling and Fitting the Side
Handle (fig. 2A, 2B)
The side handle (c) can be mounted in front or in rear
position on either side of the machine to suit both RH- and
LH-users.
WARNING: Always operate the tool with the
side handle properly assembled.
D25501, D25601
MOUNTING IN FRONT POSITION (FIG. 2A)
1. Snap the steel ring (k) over the collar (x) behind the tool
holder (m). Squeeze both ends together, mount the bush
(l) and insert the pin (q).
2. Place the side handle clamp (j) and screw on the clamp
wheel (h). Do not tighten.
WARNING: Once assembled, the side handle
clamp should never be removed.
3. Screw the side handle (c) into the bush (l) and then into
clamp wheel. Tighten securely.
4. Rotate the side handle mounting assembly to the desired
position. For drilling horizontally with a heavy drill bit,
we recommend to place the side handle at an angle of
approx. 20° for optimum control.
5. Lock the side handle mounting assembly in place by
tightening the clamp wheel (h).
