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 personal 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 II tools.
Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of

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.

PERSONAL SAFETY

Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.

Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving

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.
Property maintained tools, with sharp cutting edges are less likely to bind and are easier to control.

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 electric or gas service and that their locations have been verified with the utility 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.

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.

Motor

Your tool is powered by a D=WALT built motor designed to be used with alternating current. Voltage decrease of more than 10% will cause loss of power and overheating. All D=WALT tools are factory tested; if this tool does not operate, check the power supply.

Side Handle and Depth Rod

For operating convenience, the side handle can be installed in front or rear positions. Always operate the tool with the side handle properly assembled to maximize control of the tool.

TO MOUNT IN FRONT POSITION (FIG. 1)

1. Unscrew the side handle and disassemble the side handle clamp.

2. Snap the steel ring over the collar behind the tool holder. Squeeze both ends together, mount the bushing and insert the pin.

3. Place the side handle clamp and screw on the clamp knob. Do not tighten.

4. Insert adjustable depth rod into hole.

5. Screw the side handle into the clamp knob and tighten it.

6. 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.

7. Lock the side handle mounting assembly in place by tightening the clamp knob.

TO MOUNT IN REAR POSITION (FIG. 2)

1. Unscrew the side handle and remove it from the front position.

Leave the side handle mounting assembly in front position so that the depth adjustment rod can still be used.

1. Screw the side handle directly into one of the rear side handle positions on either side of the tool.

TO ADJUST THE DEPTH ROD

1. Insert bit into tool holder and loosen depth rod clamp nut.
2. Place drill bit onto a surface, adjust the rod to desired depth of hole. Using the depth rod will allow you to drill a hole the depth of the distance between the bit and the depth rod tip.
3. Tighten clamp nut.
   NOTE: This adjustment can be made with or without side handle in place.

Inserting and Removing Spline Drive Accessories

FIG. 3: (D25550, D25551, D25650, D25850)

TURN OFF TOOL AND DISCONNECT FROM POWER SUPPLY.

1. Unlock the tool holder by pushing the retaining pin button (J) and holding it in.
2. Insert the bit shank into the tool holder as far as it will go.

1. Release the retaining pin button.
2. Pull on the bit to be sure that it is properly locked.
3. To remove a bit unlock the tool holder as described above.

Inserting and Removing SDS-max™ Accessories

FIG.4: (D25500, D25600, D25830)

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. FIG. 5

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 FIG.6 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 DeWALT 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.

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 t 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 D2550).
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 × 21/32'' round insert tool and for SDS Max models use SDS Max insert tools.
4. Fit and adjust the side handle.
