INTENDED USE
D25501, D25601, D25602, D25603
Your rotary hammer has been designed for
professional rotary drilling and chipping applications.
D25820, D25831
Your chipping hammer has been designed for
professional chipping, chiselling and demolition
applications.
DO NOT
use under wet conditions or in 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.
• 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
(fi g. 1, 3)
D25601, D25602, D25603, D25831
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
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. 3)
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. 3)
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 (fi g. 1, 3)
D25601, D25602, D25603, D25831
The yellow brushwear indicator LED (q) 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, 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. On models fitted with Ultimate
Torque Control (UTC), the red LED indicator (r) lights
up if the anti-rotational device is activated. The red
