Active
Vibration
Control
(Fig.
1)
D25223, D25323 AND D25324 ONLY
The active vibration control reduces rebound vibration from the hammer mechanism. Reducing
hand and arm vibration allows for more comfortable use for longer periods of time and extends the
life ofthe unit.
For best vibration control, hold the tool with one hand on the main handle (B) and the other hand
on the side handle (I). Apply just enough pressure so the hammer 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.
Torque
Limiting
Clutch
All rotary hammer drills are equipped with a torque limiting clutch that 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. The torque limiting clutch has been
factory-set and cannot be adjusted.
Side
Handle
(Fig.
2)
,i_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
A side handle comes assembled with this rotary hammer. The side handle (I)can be fitted to suit
both right-hand and left-hand users.
TO ADJUST THE SIDE HANDLE
1. Loosen the side handle (I) by turning it counterclockwise.
2. Rotate the side handle to the desired position.
3. Tighten the side handle by turning it clockwise.
TO CHANGE SIDES
For right-hand users: slide the side handle clamp over the chuck, handle at the left.
For left-hand users: slide the side handle clamp over the chuck, handle at the right.
Trigger
Switch
(Fig.
1)
To start the rotary hammer, depress the trigger switch (A). To stop rotary hammer, release the
switch.
NOTE: Use lower speeds for starting holes without a centerpunch,
drilling in metal, plastics or
ceramics, or driving screws. Higher speeds are better for drilling in masonry for maximum efficiency.
VARIABLE SPEED
The variable speed trigger switch (A) permits speed control. The farther the trigger switch is
depressed, the higher the speed of the drill.
Lock-on
Button
(Fig.
1)
D25123, D25330
_WARNING:
Be sure to release the locking mechanism before disconnecting the plug from the
power supply, Failure to do so will cause the hammerdrill to start immediately the next time it is
plugged in. Damage or personal injury could result.
The lock-on button (L) is for use only when the rotary hammer is stationary, mounted in a drill press
stand or for chipping applications.
Before using the tool each time, be sure that the lock-on button release mechanism is working
freely.
D25123 ONLY
To lock the trigger switch in the on position for continuous operation, depress and hold the trigger
switch and slide the lock-off button (L) forward. The tool will continue to run.
To turn the tool off from a locked on condition, squeeze the trigger once then release it.
D25330 ONLY
To lock the trigger switch in the On position for continuous operation, depress the trigger switch
and push the lock-on button (L) in. The tool will continue to run.
To turn the tool Off from a locked on condition, squeeze the trigger once then release it.
Forward/Reverse
Slider
(Fig.

D25123, D25213, D25313, D25223, D25323, D25324
,_ WARNING: Always wait until the motor has come to a complete standstill before changing the
direction of rotation.
ACAUTION:
When reversing to clear jammed bits, be ready for strong reactive torque.
The forward/reverse slider (C) is used to reverse the rotary hammer for backing out fasteners or
jammed bits mode.
1. Push the forward/reverse slider (C) to the left (viewed when holding drill in operating position)for
forward (right-hand) rotation. See arrows on tool.
2. Push the forward/reverse slider (C) to the right for reverse (left-hand) rotation.

SDS Plus ® Chuck
(Fig.
1)
_ WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect tool
from power source before making any adjustments or removing/installing
attachments
or accessories.
A 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.
To insert bit, insert shank of bit about 3/4" (19 mm), no further than 7/8" (22 mm) into chuck. Push
and rotate bit until it locks in place. The bit will be securely held.
To release bit, pull the chuck sleeve (F)back and remove the bit.
OPERATION
i_ 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,
A WARNING: To reduce the risk ofpersonalinjury,
ALWAYS ensure workpiece is anchored
or clamped firmly. If drilling thin material, use a wood "back-up" block to prevent damage to the
material
A 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
Proper
Hand
Position
(Fig.
1, 4)
_ 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 (I), with the other hand on the main
handle (B).
Overload
Clutch
If the drill bit becomes jammed or caught, the drive to the drill spindle is interruptedby the overload
clutch. Because of the forces that occur as a result, always hold the machine securely with both
hands and take a firm stance.
Drilling
Tools
The machine is intended for hammerdrilling in concrete, brick and stone It is also suitable for drilling
without impact in wood, metal, ceramic and plastic.
Chipping
Tools
The machine is intended for chipping in concrete, brick and stone.

Drilling
_ WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect tool
from power source before making any adjustments or removing/installing
attachments
or accessories.
WARNING: To reduce the risk of personal injury, ALWAYS ensure workpiece is anchored
or clamped firmly, If drilling thin material, use a wood "back-up" block to prevent damage to the
material.
Press mode selector button (E)and turn the mode selector (D) to the drill bit symbol for drilling, to the
hammer symbol for hammering or to the hammerdrill symbol for hammerdrilling.
DRILLING OPERATION
1. For WOOD, use twist bits, spade bits, power auger bits or hole saws. For METAL, use high-
speed steel twist drill bits or hole saws. Use a cutting lubricant when drilling metals. The
exceptions are cast iron and brass which should be drilled dry. For MASONRY, use carbide-
tipped bits or masonry bits. A smooth, even flow of dust indicates the proper drilling rate.
2. Always apply pressure in a straight line with the bit. Use enough pressure to keep the drill bit
biting, but do not push hard enough to stall the motor or deflect the bit.
3. Hold tool firmly with both hands to control the twisting action of the drill.
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,
4. IF DRILL STALLS, it is usually because it is being overloaded.
RELEASE TRIGGER
IMMEDIATELY,
remove drill bit from work, and determine cause of stalling. DO NOT CLICK
TRIGGER OFF AND ON IN AN A'rrEMPT
TO START A STALLED DRILL - THIS CAN
DAMAGE THE DRILL.
5. To minimize stalling or breaking through the material, reduce pressure on drill and ease the bit
through the last fractional part of the hole.
6. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent
jamming.
7. With variable speed drills there is no need to center punch the point to be drilled. Use a slow
speed to start the hole and accelerate by squeezing the trigger harder when the hole is deep
enough to drill without the bit skipping out.
DRILLING IN METAL
An SDS Plus®to round shank adaptor chuck is required for the D25123, D25213, D25313, D25223
and the D25323. Ensure that tool is in drill-only mode. Start drilling with slow speed and increase
to full power while applying firm pressure on the tool. A smooth even flow of metal chips indicates
