Two-Stage Clutch/E-Clutch
NOTICE: Always turn the tool off before changing
torque control settings or damage to tool may result.
Two-stage clutch
D25603, D25651
Clutch Setting 1 14 is designed for most hammerdrilling
applications and is designed to easily clutch out when the
drill bit encounters re-bar or other foreign substances.
Clutch Setting 2 11 is designed for higher torque
applications such as core-bits and deep hole hammerdrilling
and is designed to clutch out at a higher torque threshold.
Move the torque control lever
needed for application.
nOTE: Allow the motor housing to rotate a little while
changing torque.
nOTE: If it is not possible to select Clutch Setting 2, run the
unit under load and try again.
Each time the tool is plugged in, it will automatically default
to Clutch Setting 1, the most sensitive setting.
E-CLUTCH™
D25603
In addition, E-Clutch™ offers increased user comfort and
safety through an on-board antirotation technology capable
of detecting if the user loses control of the hammer. When a
jam is detected, the torque and speed are reduced instantly.
The red indicator LED illuminates when the E-Clutch™

is engaged.

Electronic Speed and Impact Control
(Fig. E)
D25651, D25601, D25603, D25831,
D25851
The electronic speed and impact control allows the
use of smaller drill bits without the risk of bit breakage,
hammerdrilling into light and brittle materials without
shattering and optimal tool control for precise chipping.
To set the control dial, turn the dial
The higher the number, the greater the speed and impact
energy. Dial settings make the tool extremely adaptable for
many different appli cations. The required setting depends
on the bit size and hardness of material being drilled.
Mode Selector (Fig. A)
NOTICE: Never change the mode while the unit is
running. Tool must come to a complete stop before
activating the mode selector button or damage to the
tool may result.

CAUTION: Do not change to hammerdrill mode with
chisel bit in tool holder. Personal injury and damage
to tool may result.
The D25501, D25553, D25601, D25603, and D25651 use
two operating modes. To select the required operating
mode, rotate the mode selector
the hammerdrilling or the chipping icon. The D25831 and
D25851 use only the chipping mode.
Hammerdrilling Mode (
D25501, D25553, D25601, D25603,
D25651
The tool simultaneously rotates and impacts the
work. This mode is appropriate for all concrete and
masonry operations.
Chipping Mode (
D25831, D25851
The spindle lock is engaged during chipping mode
so the tool impacts the work without rotating. This
mode is appropriate for light chipping, chiseling and
demolition applications.
nOTE: In chipping mode, the hammerdrill can also be used
as a lever to free a jammed drill bit.
