WARNING: To reduce the risk of injury, read the instruction manual.

General Power Tool Safety Warnings

WARNING! Read all safety warnings

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



The term “power tool” in the warnings refers to your mains-operated (corded) power tool or batteryoperated (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

ENGLISH 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.

f) 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.



ENGLISH 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) BATTERY TOOL USE AND CARE a) Recharge only with the charger specified

by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.

b) Use power tools only with specifically

designated battery packs. Use of any other battery packs may create a risk of injury and fire.

c) When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws or other small metal objects that can make a connection from one terminal to another.

Shorting the battery terminals together may cause burns or a fire.

d) Under abusive conditions, liquid may be ejected from the battery, avoid contact.

If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally

seek medical help. Liquid ejected from the battery may cause irritation or burns.

6) 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 Specifi c Safety Rules for

Impact Wrenches/Drivers

Hold power tool by insulated gripping surfaces when performing an operation where the fastener may contact hidden

wiring. Fasteners contacting a “live” wire may make exposed metal parts of the power tool

“live” and could give the operator an electric shock.

Residual Risks

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.

– Risk of personal injury due to flying particles.

– Risk of burns due to accessories becoming hot during operation.

– Risk of personal injury due to prolonged use.

repair is required. Incorrect reassembly may result in a risk of electric shock, electrocution or fire.

• In case of damaged power supply cord the supply cord must be replaced immediately by the manufacturer, its service agent or similar qualified person to prevent any hazard.

• Disconnect the charger from the outlet before attempting any cleaning. This will

reduce the risk of electric shock. Removing the battery pack will not reduce this risk.

• NEVER attempt to connect 2 chargers together.

• The charger is designed to operate on standard 230 V household electrical power.

Do not attempt to use it on any other

voltage. This does not apply to the vehicular charger.




The DCB105, DCB107 and DCB112 chargers accept 10.8V, 14.4V and 18V XR Li-Ion (DCB123,

DCB125, DCB127, DCB140, DCB141, DCB142,

DCB143, DCB144, DCB145, DCB180, DCB181,

DCB182, DCB183, DCB184 and DCB185) battery packs.

These chargers require no adjustment and are designed to be as easy as possible to operate.

Charging Procedure (fi g. 2)

1. Plug the charger into an appropriate outlet before inserting battery pack.

2. Insert the battery pack (f) into the charger, making sure the pack is fully seated in the charger. The red (charging) light will blink continuously indicating that the charging process has started.

3. The completion of charge will be indicated by the red light remaining ON continuously. The pack is fully charged and may be used at this time or left in the charger.

NOTE: To ensure maximum performance and life of

Li-Ion batteries, charge the battery pack fully before first use.

Charging Process

Refer to the table below for the charge status of the battery pack.

* DCB107, DCB112: The red light will continue to blink, but a yellow indicator light will be illuminated during this operation. Once the battery has reached an appropriate temperature, the yellow light will turn off and the charger will resume the charging procedure.

The compatible charger(s) will not charge a faulty battery pack. The charger will indicate faulty battery



ENGLISH by refusing to light or by displaying problem pack or charger blink pattern.

NOTE: This could also mean a problem with a charger.

If the charger indicates a problem, take the charger and battery pack to be tested at an authorised service centre.


When the charger detects a battery that is too hot or too cold, it automatically starts a Hot/Cold Pack

Delay, suspending charging until the battery has reached an appropriate temperature. The charger then automatically switches to the pack charging mode. This feature ensures maximum battery life.

A cold battery pack will charge at about half the rate of a warm battery pack. The battery pack will charge at that slower rate throughout the entire charging cycle and will not return to maximum charge rate even if the battery warms.


XR Li-Ion tools are designed with an Electronic

Protection System that will protect the battery against overloading, overheating or deep discharge.

The tool will automatically turn off if the Electronic

Protection System engages. If this occurs, place the

Li-Ion battery on the charger until it is fully charged.

Rechargeable Battery Pack

This long life battery pack must be recharged when it fails to produce sufficient power on jobs which were easily done before. At the end of its technical life, discard it with due care for our environment:

• Run the battery pack down completely, then remove it from the tool.

• Li-Ion cells are recyclable. Take them to your dealer or a local recycling station. The collected battery packs will be recycled or disposed of properly.

Should you find one day that your D E WALT product needs replacement, or if it is of no further use to you, do not dispose of it with household waste. Make this product available for separate collection.

Separate collection of used products and packaging allows materials to be recycled and used again. Re-use of recycled materials helps prevent environmental pollution and reduces the demand for raw materials.

Local regulations may provide for separate collection of electrical products from the household, at municipal waste sites or by the retailer when you purchase a new product.

D E WALT provides a facility for the collection and recycling of D E WALT products once they have reached the end of their working life. To take advantage of this service please return your product to any authorised repair agent who will collect them on our behalf.

You can check the location of your nearest authorised repair agent by contacting your local

D E WALT office at the address indicated in this manual. Alternatively, a list of authorised D E WALT repair agents and full details of our after-sales service and contacts are available on the Internet at:
