General Power Tool Safety Warnings

WARNING! Read all safety warnings and instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

ENGLISH

SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE

The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

1) WORK AREA SAFETY

a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

2) ELECTRICAL SAFETY

a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

3) PERSONAL SAFETY

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

b) Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
i) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.

4) POWER TOOL USE AND CARE

a) Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.

e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool's operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

g) Use the power tool, accessories and tool bits etc., in accordance with these instructions taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

5) SERVICE

a) Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

Additional Safety Instructions for Rotary Hammers

• Wear ear protectors. Exposure to noise can cause hearing loss.
• Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
• Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.

Residual Risks

The following risks are inherent to the use of rotary and chipping hammers:

• Injuries caused by touching the rotating parts or hot parts of the tool
  In spite of the application of the relevant safety regulations and the implementation of safety devices, certain residual risks cannot be avoided. These are:

• Impairment of hearing.

Children should never be left alone with this product.

Soft Start Feature

D25722, D25723, D25761, D25762, D25763

The soft start feature allows the tool to accelerate 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.

Electronic Speed and Impact Control (fi g. 1, 3)

The electronic speed and impact control (g) offers the following advantages:

– use of smaller accessories without risk of breakage;
- minimised break-out when chiselling or drilling in soft or brittle materials;
- optimal tool control for precise chiselling.

Torque Limiting Clutch

WARNING: The user must always maintain a firm grip on the tool when in operation.

The torque limiting clutch 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.

NOTICE: Always turn the tool off before changing torque control settings or damage to tool may result.

COMPLETE TORQUE CONTROL (CTC) (FIG. 3) D25722/D25762

Complete Torque Control (CTC) offers the user a two-stage mechanical clutch with adjustable torque options. Adjusting the torque provides increased control for various applications.

The low setting (40 Nm) allows the tool to operate at a reduced torque level increasing control for many solid drilling applications. The high setting (80 Nm) is available for more demanding applications such as core drilling and the use of large diameter solid bits.

Refer to Setting the Two Stage Mechanical Clutch for more information.

ULTIMATE TORQUE CONTROL (UTC) D25723/D25763

In addition to the two-stage mechanical clutch, Ultimate Torque Control (UTC) offers increased user comfort and safety through an on-board, anti-rotation technology capable of detecting if

the user loses control of the hammer. When a jam is detected, the torque and speed are reduced instantly. This feature prevents self rotation of the tool reducing the occurrence of wrist injuries.

Service Indicator LEDs (fi g. 3)

The yellow brushwear indicator LED (s) lights up when the carbon brushes are nearly worn out to indicate that the tool needs servicing within the next 8 hours of use.

D25721, D25722, D25723, D25761, D25762, D25763

The red service indicator LED (r) lights up if the lock-on button (b) is used in any mode except the chipping mode. On models fitted with Ultimate Torque Control (UTC), the red LED indicator (r) lights up if the anti-rotational device is activated. The red indicator starts to flash if there is a fault with the tool or the brushes have completely worn out (refer to

Brushes under Maintenance).

D25871

The red service indicator LED (r) lights up if there is a fault with the tool or the brushes have completely worn out (refer to Brushes under Maintenance).

Fully Vibration-dampened Main Handle (fi g. 1)

The dampers in the main handle (d) absorb the vibrations transmitted to the user. This improves user comfort during the operation.

Electrical Safety

The electric motor has been designed for one voltage only. Always check that the power supply corresponds to the voltage on the rating plate.

Your DEWALT tool is double insulated in accordance with EN 60745; therefore no earth wire is required.

VG: 115 V units have to be operated via a fail-safe isolating transformer with an earth screen between the primary and secondary winding.

If the supply cord is damaged, it must be replaced by a specially prepared cord available through the DEWALT service organisation.

Mains Plug Replacement (U.K. & Ireland Only)

If a new mains plug needs to be fitted:

- Safely dispose of the old plug.

• Connect the brown lead to the live terminal in the plug.
• Connect the blue lead to the neutral terminal.

WARNING: No connection is to be made to the earth terminal.

Follow the fitting instructions supplied with good quality plugs. Recommended fuse: 13 A.

1. Fit and adjust the side handle (c).
2. Place the centerdrill on the spot and switch on the tool. Drill until the core penetrates into the concrete approximately 1 cm.
3. Stop the tool and remove the centerdrill. Place the core bit back into the hole and continue drilling.
4. 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 centerdrill completely through the structure. Then drill the cored hole halfway from each side.
5. Always turn the tool off when work is finished and before unplugging.

Chipping and Chiselling (fi g. 1)

1. Insert the appropriate chisel and rotate it by hand to lock it into one of 24 positions.
2. Set the mode selector switch (f) to the hammering only position.
3. Set the electronic speed and impact control dial (g).
4. Fit and adjust the side handle (c).
5. Turn the tool on and start working.
6. Always turn the tool off when work is finished and before unplugging.

MAINTENANCE

Your DEWALT power tool has been designed to operate over a long period of time with a minimum of maintenance. Continuous satisfactory operation depends upon proper tool care and regular cleaning.

WARNING: To reduce the risk of injury, turn unit off and disconnect machine from power source before installing and removing accessories, before adjusting or changing set-ups or when making repairs. Be sure the trigger switch is in the OFF position. An accidental start-up can cause injury.

This machine is not user-serviceable. Take the tool to an authorised DEWALT repair agent after approximately 150 hours of use. If problems occur before this time, contact an authorised DEWALT repair agent.

Brushes (fi g. 3)

The carbon brushes are not user-serviceable. Take the tool to an authorized DEWALT repair agent.

The yellow brushwear indicator LED (s) lights up when the carbon brushes are nearly worn out. After a further 8 hours of use or after the brushes have completely worn out, the motor will automatically be shut off.

Tool maintenance needs to be carried out as soon as the service indicator (r) lights up.

Lubrication

Your power tool requires no additional lubrication.

Cleaning

WARNING: Blow dirt and dust out of the main housing with dry air as often as dirt is seen collecting in and around the air vents. Wear approved eye protection and approved dust mask when performing this procedure.

WARNING: Never use solvents or other harsh chemicals for cleaning the non-metallic parts of the tool. These chemicals may weaken the materials used in these parts. Use a cloth dampened only with water and mild soap. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.
