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
- 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
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
used in any mode except the chipping mode. On models fitted with
Ultimate Torque Control (UTC), the red LED indicator
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).

The red service indicator LED 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.

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
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
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
pull the bit out of the tool holder
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

Setting the Electronic Speed and Impact Control Dial
(Fig. A, C)
D25601, D25604, D25831

Turn the dial 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;
• when breaking or drilling in harder materials, set the dial to a
high setting.
