Electronic Speed and Impact Control
(Fig. E)
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 D25604 and D25652 use two operating modes. To
select the required operating mode, rotate the mode
selector until the arrow points to the hammerdrilling or
6
the chipping icon. The D25831 and D25851 use only the
chipping mode.
Rotary Hammering Mode (
D25604, D25652
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.
Chisel Bit adjustment (
D25604, D25652, D25831, D25851
Turn the mode selector to one of the chisel bit adjustment
icons to adjust the chisel to the desired position. There are
multiple positions to set the angle of the chisel. After finding
the desired position, slightly maneuver the chisel bit back
and forth to ensure the chisel is properly engaged.

OPERATION

WARNING: To reduce the risk of serious personal
injury, turn unit off and disconnect it from
power source before making any adjustments or
removing/installing attachments or accessories.
An accidental start-up can cause injury.

WARNING: To reduce the risk of personal injury,
ALWAYS ensure workpiece is anchored or
clamped firmly. If hammerdrilling thin material,
use a wood "back-up" block to prevent damage to
the material.

WARNING: To reduce the risk of personal injury,
ALWAYS operate the tool with the side handle
properly installed and securely tightened. Failure
to do so may result in the side handle slipping during
tool operation and subsequent loss of control. Hold
tool with both hands to maximize control.

WARNING: Drill may stall if overloaded causing a
sudden twist. Always expect the stall. Grip the drill
firmly with both hands to control the twisting action
and avoid injury.
nOTE: Operating temperature of this tool is 19 ˚F to 104 ˚F
(-7 ˚C to +40 ˚C). Using the tool outside of this temperature
range will decrease the life of the tool.
Proper Hand Position (Fig. F)

WARNING: To reduce the risk of serious personal injury,
ALWAYS use proper hand position as shown.
