Your rotary hammer has been designed for professional rotary
drilling and chipping applications.
D25871
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.

Soft Start Feature
D25722, D25723, D25761, D25762, D25763
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)
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) D25722 /
D25762
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) D25723
/ D25763
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
