EngLIsH
The D25820, D25831 chipping hammers have been designed for
professional chipping, chiselling and demolition applications.
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, D25602, D25603, 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, D25602, D25603, 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.
NOTICE: Always turn the tool off before changing torque control
settings or damage to tool may result.
Complete Torque Control (CTC) (Fig. C) D25602
Complete Torque Control (CTC) offers the user a two-stage mechanical
clutch with adjustable torque options. Adjusting the torque provides
increased control for various applications.
The low setting (40 Nm) allows the tool to operate at a reduced torque
level increasing control for many solid drilling applications. The high setting
(80 Nm) is available for more demanding applications such as core drilling
and the use of large diameter solid bits.
Refer to Setting the Two Stage Mechanical Clutch for more information.
Ultimate Torque Control (UTC) (Fig. C) D25603
In addition to the two-stage mechanical clutch, Ultimate Torque Control
(UTC) 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)

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. Be sure the trigger switch is in the OFF position. An
accidental start-up can cause injury.
Assembling and Fitting the Side Handle
(Fig. B)
The side handle 3 can be mounted on either side of the machine to suit
both right- and left-handed users.

WARNING: Always operate the tool with the side handle
properly assembled.

1. Snap the steel ring 10 over the collar
Squeeze both ends together, mount the bush

2. Place the side handle clamp 9
not tighten.

WARNING: Once assembled, the side handle clamp should never
be removed.
3. Screw the side handle 3 into the bush
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 approximately 20° for optimum control.
5. Lock the side handle mounting assembly in place by tightening the
clamp wheel 8 .

Inserting and Removing SDS Max® Accessories
(Fig. A, D)
This machine uses SDS Max bits and chisels (refer to the inset in figure DB

for a cross-section of an SDS Max ® bit shank).
1. Clean the bit shank.
2. Pull back the locking sleeve 13
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.
