ENGLISH
DO NOT use under wet conditions or in the 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.
• Young children and theinfirm. This appliance is not intended for use
by young children or infirm persons withoutsupervision.
• This product is not intended for use by persons (including children)
suffering from diminished physical, sensory or mental abilities; lack of
experience, knowledge or skills unless they are supervised by a person
responsible for theirsafety. Children should never be left alone with
thisproduct.
Soft Start Feature
D25601, D25604, D25831
The soft start feature allows the tool to accelerate 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 (Fig. A, C)
D25601, D25604, D25831
The electronic speed and impact control
7
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

WARNING: The user must always maintain a firm grip on the tool
when inoperation.
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.
Anti-Rotation System (Fig.C)
D25604
Ant-Rotation System offers increased user comfort and safety through an
on-board, anti-rotation technology capable of detecting if the user loses
control of thehammer. When a jam is detected, the torque and speed are
reducedinstantly. This feature prevents self rotation of the tool reducing the
occurrence of wristinjuries.
Service Indicator LEDs (Fig. A, C)
D25601, D25604, D25831
The yellow brushwear indicator LED
17
lights up when the carbon brushes
are nearly worn out to indicate that the tool needs servicing within the next
8 hours ofuse.
D25604
The red service indicator LED
16
lights up if the lock-on button
2
is
used in any mode except the chippingmode. On models fitted with
Ultimate Torque Control (UTC), the red LED indicator
16
lights up if the
anti-rotational device isactivated. 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).
D25601, D25831
The red service indicator LED
16
lights up if there is a fault with
the tool or the brushes have completely worn out (refer to Brushes
underMaintenance).
Under exposure of certain electromagnetic phenomena(fast transients) it
can happen that the machine will reduce speed down to zero RPM. This
will be shown by flashing of the service indicator. To undo this mode the
machine needs to be switched off and on one time. After cycling the trigger
switch the machine is back in normal operating mode.
Fully Vibration-Dampened Main Handle (Fig. A)
D25601, D25604, D25831
The dampers in the main handle
4
absorb the vibrations transmitted to
theuser. This improves user comfort during theoperation.
ASSEMBLY AND ADJUSTMENTS

WARNING: To reduce the risk of serious personal injury,
turn tool off and disconnect tool from power source before
making any adjustments or removing/installing attachments
oraccessories. An accidental start-up can causeinjury.
Fitting the Side Handle (Fig. B)
The side handle
3
clamps to the mounting area
12
of the gear case and
may be rotated 360˚ to permit right- or left-hand use. The side handle
must be tightened sufficiently to resist the twisting action of the tool if the
accessory binds or stalls. Be sure to grip the side handle at the far end to
control the tool during astall.
To loosen side handle, rotatecounterclockwise.
Inserting and Removing SDS Max Accessories
(Fig. A, D)
This machine uses SDS Max bits and chisels (refer to the inset in FigureD for
a cross-section of an SDS Max bit shank).
1. Clean the bitshank.
2. Pull back the locking sleeve
11
and insert the bitshank.
3. Turn the bit slightly until the sleeve snaps intoposition.
4. Pull on the bit, to check if it is properlylocked. The hammering function
requires the bit to be able to move axially several centimetres when
locked in the toolholder.
5. To remove a bit pull back the tool holder locking sleeve/collar
11
and
pull the bit out of the tool holder
10
.
Selecting the Operating Mode (Fig. A)
Hammerdrilling:
D25501, D25601, D25604
for concrete, brick, stone and masonry drillingoperations.
Hammering only:
D25501, D25601, D25604, D25831
for chiselling and demolitionapplications. In this mode the tool
can also be used as a lever to free a jammed drillbit.
1. To select the operating mode, rotate the mode selector switch
6
until
it points to the symbol of the requiredmode.
It may be neccessary to twist the tool holder
10
slightly to allow the
mode selector switch
6
to pass the position.
2. Check that the mode selector switch
6
is locked inplace.
Indexing the Chisel Position (Fig. E)
The chisel can be indexed and locked into 18 differentpositions.
1. Rotate the mode selector switch
6
until it points towards the
position.
2. Rotate the chisel in the desiredposition.
3. Set the mode selector switch
6
to the “hammering only”position.
4. Twist the chisel until it locks inposition.
Setting the Electronic Speed and Impact Control Dial
(Fig. A, C)
D25601, D25604, D25831
Turn the dial
7
to the desiredlevel. Turn the dial upwards for higher
speed and downwards for lowerspeed. The required setting is a matter of
experience, e.g.
• when chiselling or drilling in soft, brittle materials or when minimum
break-out is required, set the dial to a low setting;
