2. Slide the D-shaped handle (Q) and assembly over the tool holder (M) and onto the collar (L) in
the mounting area (Z). The correct position of the D-shaped handle (Q) is between head and
middle of the tube.
3. Adjust the D-shaped handle to the desired angle.
4. Slide and rotate the D-shaped handle to the desired position.
5. Lock the D-shaped handle in place by securely tightening the knob (R) so that the D-shaped
handle assembly will not rotate.
SHOCKS Active Vibration Control
D25651, D25601, D25603, D25831, D25851
For best vibration control, hold the tool with one hand on the main handle (D) and the other hand on
the side handle (C) or D-shaped handle (Q). Apply just enough pressure so the damping device on
the main handle is approximately mid stroke. The hammer only needs enough pressure to engage
the active vibration control. Applying too much pressure will not make the tool drill or chip faster
and active vibration control will not engage.
Inserting and Removing Spline Drive Accessories (Fig. 5)
D25553, D25651, D25851
WARNING: Burn hazard. ALWAYS wear gloves when changing bits. Accessible metal parts on
the tool and bits may get extremely hot during operation. Small bits of broken material may damage
bare hands.
WARNING: Do not attempt to tighten or loosen drill bits (or any other accessory) by gripping the
front part of the chuck and turning the tool on. Damage to the chuck and personal injury may occur.
1. Insert the bit shank into the tool holder (M) as far as it will go. The groove on the chisel shank
(S) must be aligned with the symbol (T) on the toolholder. If inserted correctly, the locking sleeve
(P) moves back to the end position and shows a closed lock symbol.
2. Pull on the bit to be sure that it is properly locked.
3. If the chisel groove is not aligned with the symbol, or is not inserted to the complete depth the
lock symbol remains open.
To remove the bit, pull back the locking sleeve and pull the bit out.
Inserting and Removing SDS Max Accessories (Fig. 6)
D25501, D25601, D25603, D25831
1. Pull back the locking sleeve (P) and insert the bit shank. The bit shank must be clean.
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.
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 (U) 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 (V) 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 (Y) to Clutch Setting 1 or 2 as 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 (X) illuminates when the
C
E-Clutch™ is engaged.
Electronic Speed and Impact Control (Fig. 7)
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 (G) to the desired level. 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. 1)
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 and D25603, D25651 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 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.
S
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 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.
Indicator Lights (Fig. 1, 7)
The yellow brush wear indicator LED (W) lights up when the carbon brushes are nearly worn out
indicating that the tool needs servicing within the next 8 hours of use.
The red indicator LED (X) lights up if the lock-on slider (B) and/or E-Clutch™ is engaged in any
mode except the chipping mode.
The red indicator LED (X) starts to flash if there is a fault with the tool or the brushes have completely
worn out (refer to Repairs under Maintenance).

OPERATION

WARNING: To reduce the risk of injury, turn unit off and disconnect it from power
source before installing and removing accessories, before adjusting or when making
repairs. 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.
D 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.
Proper Hand Position (Fig. 8)
WARNING: To reduce the risk of serious personal injury, ALWAYS use proper hand position as
shown.
WARNING: To reduce the risk of serious personal injury, ALWAYS hold securely in anticipation
of a sudden reaction.
Proper hand position requires one hand on the side handle (C) or D-shaped handle (Q), with the
other hand on the main handle (D).
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.
Trigger Switch (Fig. 1)
D25501, D25553, D25601, D25603, D25651
To turn the tool on, depress the trigger switch (A). To stop the tool, release the trigger switch.
In chipping mode only, lock the trigger switch on by pushing the lock-on slider (B) upward 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 chipping mode. The machine will stop running when
trying to engage the lock-on slider in hammerdrilling mode. The motor will stop if the lock-on slider is
activated when changing from chisel mode into hammerdrilling mode.
D25831, D25851
For continuous operation, move the toggle switch (A) to the on position. To stop continuous
operation, move the toggle switch to the off position.
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.
