electric shock if your body is grounded.

Don’t expose power tools to rain or wet conditions. Water

entering a power tool will increase the risk of electric shock. Other

liquids, such as perspiration, present the same hazard.

Do not abuse the cord. Never use the cord to carry the tools or

pull the plug from an outlet. Keep cord away from heat, oil, sharp

edges or moving parts. Replace damaged cords immediately.

Damaged cords increase the risk of electric shock.

When operating a power tool outside, use an outdoor

extension cord marked “W-A” or “W.” These cords are rated

for outdoor use and reduce the risk of electric shock. When using

an extension cord, be sure to use one heavy enough to carry the

current your product will draw. An undersized cord will cause a

drop in line voltage resulting in loss of power and overheating.

The following table shows the correct size to use depending on

cord length and nameplate ampere rating. If in doubt, use the next

heavier gage. The smaller the gage number, the heavier the cord.

Important Safety Instructions

WARNING: Read and understand all instructions. Failure to

follow all instructions listed below, may result in electric shock, fire

and /or serious persoinal injury.

SAVE THESE INSTRUCTIONS

WORK AREA

Keep your work area clean and well lit. Cluttered benches and

dark areas invite accidents.

Do not operate power tools in explosive atmospheres, such as

in the presence of flammable liquids, gases, or dust. Power

tools create sparks which may ignite the dust or fumes.

Keep bystanders, children, and visitors away while operating

a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

Grounded tools must be plugged into an outlet properly

installed and grounded in accordance with all codes and

ordinances. Never remove the grounding prong or modify the

plug in any way. Do not use any adapter plugs. Check with a

qualified electrician if you are in doubt as to whether the outlet is

properly grounded. If the tools should electrically malfunction or

break down, grounding provides a low resistance path to carry

electricity away from the user. Applicable only to Class I

(Grounded) tools.

Double insulated tools are equipped with a polarized plug (one

blade is wider than the other.) This plug will fit in a polarized

outlet only one way. If the plug does not fit fully in the outlet,

reverse the plug. If it still does not fit, contact a qualified electrician

to install a polarized outlet. Do not change the plug in any way.

Double Insulation eliminates the need for the three wire

grounded power cord and grounded power supply system.

Applicable only to Class ll tools.

Avoid body contact with grounded surfaces such as pipes,

radiators, ranges and refrigerators. There is an increased risk of

582429-00/D25500 etc 1/29/03 9:29 AM Page 1

Check for misalignment or binding of moving parts, breakage

of parts, and any other condition that may affect the tools

operation. If damaged, have the tool serviced before using. Many

accidents are caused by poorly maintained tools.

Use only accessories that are recommended by the

manufacturer for your model. Accessories that may be suitable

for one tool, may become hazardous when used on another tool.

Keep air vents clear of debris. Reduced air flow may cause the

motor to overheat.

SERVICE

Tool service must be performed only by qualified repair

personnel. Service or maintenance performed by unqualified

personnel could result in a risk of injury.

When servicing a tool, use only identical replacement parts.

Follow instructions in the Maintenance section of this manual.

Use of unauthorized parts or failure to follow maintenance

instructions may create a risk of electric shock or injury.

Additional Safety Instructions for Rotary

Hammers

Hold tool by insulated gripping surfaces (side handle and rear

handles) when performing an operation where the cutting tool

may contact hidden wiring or its own cord. Contact with a “live”

wire will make exposed metal parts of the tool “live” and shock the

operator. Be certain that the material being drilled does not conceal

elctric or gas service and that their locations have been verified

with the untility companies.

Wear ear protectors when using the tool for extended periods.

Prolonged exposure to high intensity noise can cause hearing loss.

Always use the side handle supplied with the tool. Keep a firm

grip on the tool at all times. Do not attempt to operate this tool

without holding it with both hands. Operating this tool with one

hand will result in loss of control. Breaking through or encountering

hard materials such as re-bar may be be hazardous as well.

Tighten the side handle securely before use.

English

parts. Loose clothes, jewelry, or long hair can be caught in moving

parts. Air vents may cover moving parts and should be avoided as

well.

Avoid accidental starting. Be sure switch is off before plugging in.

Carrying tools with your finger on the switch or plugging in tools

that have the switch on invites accidents.

Remove adjusting keys or wrenches before turning the tool

on. A wrench or a key that is left attached to a rotating part of the

tool may result in personal injury.

Do not overreach. Keep proper footing and balance at all

times. Proper footing and balance enables better control of the tool

in unexpected situations.

Use safety equipment. Always wear eye protection. Dust mask,

non-skid safety shoes, hard hat, or hearing protection must be

used for appropriate conditions.

TOOL USE AND CARE

Use clamps or other practical way to secure and support the

workpiece to a stable platform. Holding the work by hand or

against your body is unstable and may lead to loss of control.

Do not force tool. Use the correct tool for your application. The

correct tool will do the job better and safer at the rate for which it is

designed.

Do not use tool if switch does not turn it on or off. Any tool that

cannot be controlled with the switch is dangerous and must be

repaired.

Disconnect the plug from the power source before making any

adjustments, changing accessories, or storing the tool. Such

preventive safety measures reduce the risk of starting the tool

accidentally.

Store idle tools out of reach of children and other untrained

persons. Tools are dangerous in the hands of untrained users.

Maintain tools with care. Keep cutting tools sharp and clean.

Properly maintained tools, with sharp cutting edges are less likely

to bind and are easier to control.

English

Wear safety goggles or other eye protection. Hammering

operations cause chips to fly. Flying particles can cause permanent

eye damage. Wear a dust mask or respirator for applications that

generate dust. Ear protection may be required for most

applications.

Keep a firm grip on the tool at all times. Do not attempt to

operate this tool without holding it with both hands. It is

recommended that the side handle be used at all times. Operating

this tool with one hand will result in loss of control. Breaking

through or encountering hard materials such as re-bar may be

hazardous as well.

Do not operate this tool for long periods of time. Vibration

caused by hammer action may be harmful to your hands and arms.

Use gloves to provide extra cushion and limit exposure by taking

frequent rest periods.

Do not recondition bits yourself. Chisel reconditioning should be

done by an authorized specialist. Improperly reconditioned chisels

could cause injury.

Wear gloves when operating tool or 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.

Never lay the tool down until the bit has come to a complete

stop. Moving bits could cause injury.

Do not strike jammed bits with a hammer to dislodge them.

Fragments of metal or material chips could dislodge and cause

injury.

Slightly worn chisels can be resharpened by grinding.

Keep the power cord away from the rotating bit. Do not wrap

the cord around any part of your body. An electric cord wrapped

around a spinning bit may cause personal injury and loss of control

NOTE: Do not overheat the bit (discoloration) while grinding a new

edge. Badly worn chisels require reforging. Do not reharden and

temper chisels.

CAUTION: Wear appropriate personal hearing protection during

use. Under some conditions and duration of use, noise from this

product may contribute to hearing loss.

WARNING: Some dust created by power sanding, sawing, grinding,

drilling, and other construction activities contains chemicals known to

cause cancer, birth defects or other reproductive harm. Some

examples of these chemicals are:

• lead from lead-based paints,

• crystalline silica from bricks and cement and other masonry

products, and

• arsenic and chromium from chemically-treated lumber (CCA).

Your risk from these exposures varies, depending on how often you do

this type of work. To reduce your exposure to these chemicals: work

in a well ventilated area, and work with approved safety equipment,

such as those dust masks that are specially designed to filter out

microscopic particles.

Avoid prolonged contact with dust from power sanding,

sawing, grinding, drilling, and other construction activities.

Wear protective clothing and wash exposed areas with soap

and water. Allowing dust to get into your mouth, eyes, or lay on the

skin may promote absorption of harmful chemicals.

TURN OFF TOOL AND DISCONNECT FROM POWER SUPPLY.

1. Pull back the tool holder locking sleeve (A) and insert the bit shank.

2. Turn the bit slightly until the sleeve snaps back in position.

3. Pull on the bit to be sure that it is properly locked. The hammering

function requires the bit to be able to move axially several

centimeters when locked in the tool holder.

4. To remove bit, pull back the tool holder locking sleeve and pull the

bit out of the tool holder.

Soft Start Feature (All

Models)

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.

Torque Limiting Clutch

All rotary hammers are equipped with a torque limiting clutch that

reduces the maximum torque reaction transmitted to the operator in the

case of a jamming drill bit. This feature also prevents the gearing and

motor from stalling. The torque limiting clutch has been factory set

and cannot be adjusted.

Electronic Speed and Impact Control

(Fig. 5)

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 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. 6 & 7)

Your rotary hammer (all units except D25550) can

be used in two operating modes. In hammer

drilling mode, the tool simultaneously rotates and

impacts the work. This mode is appropriate for

all concrete and masonry operations. In the

hammering-only mode, the spindle-lock on the

tool is engaged. The tool only impacts the work

without rotating. This mode is appropriate for

light chipping, chiseling and demolition

applications.

NOTE: In impact-only mode, the hammer can

also be used as a lever to free a jammed drill bit.

To select the required operating mode, rotate

the selector lever over the safety lock until it covers the correct symbol.

SERVICE AND POWER INDICATOR LEDS (D25600, D25650)

The red service indicator LED lights up when the carbon brushes are

nearly worn out to indicate that the tool needs servicing. After

approximately 8 hours of use the motor will automatically be shut off.

Take the tool to a D

EWALT service location for routine inspection and

maintenance.

DRILLING WITH A SOLID BIT

1. Set the speed and impact control dial.

2. Set the model selector to the “hammer drilling” position (for all units

except D25550).

3. Insert the appropriate drill bit.

4. Fit and adjust the side handle.

English

5. If necessary, set the drilling depth rod.

6. Mark the spot where the hole is to be drilled.

7. Place the drill bit on the spot and press the ON/OFF switch.

8. Push with only enough force so that the hammer beats smoothly.

The hammer only needs enough pressure or force to engage the

mechanism. Pushing harder will not make the hammer drill faster.

9. To stop the tool, release the ON/OFF switch. Always turn the tool off

when work is finished and before unplugging.

DRILLING WITH A CORE BIT

1. Turn the speed and impact control dial to the maximum torque

position. (D25550, D25500, D25551, D25600, D25650, )

2. Set the model selector to the “hammer drilling,” position (for all units

except D25550).

3. Fit and adjust the side handle.

4. Assemble the centering bit and adapter shank into core bit.

5. Mark the spot where the hole is to be drilled.

6. Place the centering bit on the spot and press the ON/OFF switch.

NOTE: Some core drills require the removal of centering bit after about

1 cm of penetration. If so, remove and continue drilling.

7. 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.

8. To stop the tool, release the ON/OFF switch. Always turn the tool off

when work is finished and before unplugging.

CHIPPING AND CHISELING

1. Set the model selector to the “hammering only with spindle lock”

position (all models except D25550).

2. Set the impact control dial to desired impact energy.

3. Insert the appropriate chisel and rotate it by hand to lock it into the

desired position. For spline units, use a 3/4” hex x 21/32” round

insert tool and for SDS Max models use SDS Max insert tools.

4. Fit and adjust the side handle.
