Side Handle (Fig. 3)
CAUTION: Always operate the tool with the side handle properly assembled. Hold tool with
both hands to maximize control.
The side handle clamps to the front barrel (collar) and may be rotated 360˚ to permit right-
or left-hand use. For operating convenience, the side handle can be installed in front or rear
positions.
TO MOUNT IN FRONT POSITION (FIG. 3)
1. Unscrew the side handle (C) and disassemble the side handle clamp (J).
2. Snap the steel ring (K) over the collar (L) behind the tool holder (M). Squeeze both ends of
the steel ring together. Mount the bushing (N) and insert the pin (O).
3. Slide the side handle clamp (J) and bushing into the clamp knob (H) – do not tighten.
4. Screw the side handle into the clamp knob (H) and tighten.
5. Rotate the side handle mounting assembly to the desired position. For drilling horizontally
with a heavy drill bit, place the side handle assembly at an angle of approximately 20˚ to the
tool for optimum control.
6. Lock the side handle mounting assembly in place by tightening the clamp knob (H).
TO MOUNT IN REAR POSITION (FIG. 3)
1. Unscrew the side handle (C) and remove it from the side handle mounting assembly. Leave
the side handle mounting assembly in the front position.
2. Screw the side handle directly into one of the rear side handle positions (I) on either side of
the tool.
Active Vibration Control (Fig. 1)
For best vibration control, hold the tool with one hand on the main handle (D) and the other hand
on the side handle (C). Apply just enough pressure so the hammer is approximately mid-stroke.
The hammer only needs enough pressure to engage the active vibraton control. Applying too
much pressure will not make the tool drill or chip faster and active vibration control will not
engage.
Inserting and Removing SDS max™ Accessories (Fig. 3)
CAUTION: TURN OFF TOOL AND DISCONNECT FROM POWER SUPPLY.
1. Pull back the locking sleeve (P) and insert the bit shank. The bit shank must be clean and
slightly lubricated.
2. Turn the bit slightly until the sleeve snaps back into position.
3. Ensure the bit is properly engaged.
NOTE: The bit needs to move several centimeters in and out of the tool holder (M) when
properly engaged.
4. To remove the bit, pull back the locking sleeve and pull the bit out.
Complete Torque Control (Fig. 4)
CAUTION: Always turn the tool off before changing torque control settings or damage to tool
may result.
The Complete Torque Control (CTC) feature of this tool is designed to provide additional control
by providing a two-stage clutch mechanism.
Clutch setting #1 (Q) is designed for most drilling applications and is designed to easily clutch
out when the drill bit encounters re-bar or other foreign substances.
Clutch setting #2 (R) is designed for higher torque applications such as core-bits and deep hole
drilling.
NOTE: Allow the motor housing to rotate a little while changing torque.
Each time the tool is plugged in, it will automatically default to clutch setting #1, the most
sensitive setting.
Electronic Speed and Impact Control (Fig. 4)
The electronic speed and impact control allows the use of smaller drill bits without the risk of bit
breakage, drilling into light and brittle materials without shattering and optimal tool control for
precise chiseling.
To set the control dial, turn the dial (G) to the desired level. The higher the number, the greater
the speed and impact energy. Dial settings make the tool extremely flexible and adaptable for
many different applications. The required setting depends on the bit size and hardness of
material being drilled.
Mode Selector (Fig. 1)
CAUTION: Never change the mode while the unit is running.
CAUTION: Do not change to hammerdrill mode with chisel bit in tool holder. Personal injury
and damage to tool may result.
The D25701 and D25730 use two operating modes. To select the required operating mode,
rotate the mode selector (F) until the arrow points to the hammerdrilling or the chipping icon. The
D25890 uses only the chipping mode.
HAMMERDRILLING MODE ( )
The tool simultaneously rotates and impacts the work. This mode is appropriate for all concrete
and masonry operations.
CHIPPING MODE ( )
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 ( )
Turn the mode selector to one of the chisel bit adjustment icons to adjust the chisel to the desired
position. There are 24 possible 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.
Power Indicator Lights (Fig. 4)
The red LED light (S) indicates a serious problem and the tool should be taken to a D
authorized service center for repair.
The yellow LED light (T) indicates when brushes are nearly worn and the tool needs servicing.
After approximately 8 hours of use, the motor will automatically shut off. The tool should be taken
to a D WALT authorized service center for routine inspection and maintenance.
E
OPERATION
NOTE: Operating temperature of this tool is 19˚ to 104˚ F (-7 to +40˚ C). Using the tool outside
of this temperature range will decrease the life of the tool.
Switch (Fig. 1)
To turn the tool on, depress the trigger switch (A). To stop the tool, release the trigger switch. To
lock the trigger switch on, push the lock-on slider (B) upwards while depressing the trigger
switch.
To deactivate the lock-on slider, depress the trigger switch once then release.
The lock-on slider may only be activated in chisel mode. The machine will stop running when
trying to engage the lock-on slider in drill mode. The motor will stop if the lock-on slider is
activated when changing from chisel mode into drill mode.
SOFT START FEATURE
The soft start feature allows you to build up speed 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.
Drilling (D25701, D25730)
NOTE: The D25890 has only chipping mode with no drilling capability.
DRILLING WITH A SOLID BIT
1. Set the model selector to hammerdrilling mode.

4. Insert the appropriate drill bit.
5. Adjust the side handle (front or rear position).
6. Mark the spot where the hole is to be drilled.
7. Place the drill bit on that mark and depress the trigger switch.
8. Apply only enough pressure to engage active vibration control (refer to Active Vibration
Control).
9. To stop the tool, release the trigger switch. Always turn the tool off when work is finished and
before unplugging.
DRILLING WITH A CORE BIT
CAUTION: Do not use a core bit for drilling wood. Personal injury and damage to tool may
result.
1. Set the model selector to hammerdrilling mode.
2. Move the torque control lever to Setting 2 (R).
3. Turn the speed and impact control dial to the maximum torque position.
4. Adjust the side handle (front or rear position).
5. Assemble the centering bit and adapter shank into core bit.
6. Mark the spot where the hole is to be drilled.
7. Place the centering bit on that mark and depress the trigger switch.
NOTE: Some core drills require the removal of centering bit after about 1cm of penetration. If
so, remove and continue drilling.
8. When drilling through a structure thicker than the depth of the core bit, break away the
round cylinder of concrete or core inside the bit at regular intervals. To avoid unwanted
breaking away of concrete around the hole, first drill a hole the diameter of the centering
bit completely through the structure. Then drill the cored hole halfway from each side of
the structure.
