GENERAL POWER TOOL SAFETY WARNINGS

• WARNING: Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.

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 the 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 that may ignite 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 a 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 energizing 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 jewelry. Keep your hair and clothing away from moving parts. Loose clothes, jewelry 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.

   • h ) Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

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 remove the battery pack, if detachable, 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 and accessories. 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.
   • h ) Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

5. Battery Tool Use and Care

   • b ) Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers. .

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 the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

• 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.

• Use clamps or another 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.

• 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. Tighten the side handle securely before use.

• 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.

• Do not overheat the bit (discoloration) while grinding a new edge. Badly worn chisels require reforging. Do not reharden and temper the chisel.

Residual Risks
The following risks are inherent to the use of rotary 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.

• Risk of squeezing fingers when changing the accessory.

• Health hazards caused by breathing dust developed when working in concrete and/or masonry.

• 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.

Chargers

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

Electrical Safety
The electric motor has been designed for one voltage only. Always check that the battery pack voltage corresponds to the voltage on the rating plate. Also make sure that the voltage of your charger corresponds to that of your mains.
Your DeWALT charger is double insulated in accordance with EN60335; therefore no earth wire is required. If the supply cord is damaged, it must be replaced only by DEWALT or an authorized service organization.

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: 3 A.
  Using an Extension Cable
  An extension cord should not be used unless absolutely necessary. Use an approved extension cable suitable for
  the power input of your charger (see Technical Data). The minimum conductor size is 1 mm2; the maximum length is 30 m.
  When using a cable reel, always unwind the cable completely.

• In case of a damaged power supply cord, the supply cord must be replaced immediately by the manufacturer, its service agent or a similarly 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 two chargers together.

• The charger is designed to operate on standard
  230V household electrical power. Do not attempt to use it on any other voltage. This does not apply to the vehicular charger.

Charging a Battery (Fig. B)

1. Plug the charger into an appropriate outlet before inserting the battery pack.
2. Insert the battery pack  8  into the charger, making sure the battery pack is fully seated in the charger. The red (charging) light will blink repeatedly indicating that the charging process has started.
3. The completion of charge will be indicated by the red light remaining ON continuously. The battery pack is fully charged and may be used at this time or left in the charger. To remove the battery pack from the charger, push the battery release button  9  on the battery pack.
   NOTE: To ensure maximum performance and life of lithium-ion battery packs, charge the battery pack fully before first use.
   Charger Operation
   Refer to the indicators below for the charge status of the battery pack.

• The red light will continue to blink, but a yellow indicator light will be illuminated during this operation. Once the battery pack 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 a faulty battery by refusing to light.

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 authorized service center.
Hot/Cold Pack Delay
When the charger detects a battery pack that is too hot or too cold, it automatically starts a Hot/Cold Pack Delay, suspending charging until the battery pack has reached an appropriate temperature. The charger then automatically switches to the pack charging mode. This feature ensures maximum battery pack life. A cold battery pack will charge at a slower rate than a warm battery pack. The battery pack will charge at that slower rate throughout the entire charging cycle and will not return to the maximum charge rate even if the battery pack warms. The DCB118 charger is equipped with an internal fan designed to cool the battery pack. The fan will turn on automatically when the battery pack needs to be cooled. Never operate the charger if the fan does not operate properly or if ventilation slots are blocked. Do not permit foreign objects to enter the interior of the charger.

Electronic Protection System
XR Li-Ion tools are designed with an Electronic Protection System that will protect the battery pack against overloading, overheating or deep discharge.
The tool will automatically turn off if the Electronic Protection System engages. If this occurs, place the lithium-ion battery pack on the charger until it is fully charged.

Wall Mounting
These chargers are designed to be wall mountable or to sit upright on a table or work surface. If wall mounting, locate the charger within reach of an electrical outlet, and away from a corner or other obstructions which may impede airflow. Use the back of the charger as a template for the location of the mounting screws on the wall. Mount the charger securely using drywall screws (purchased separately) at least 25.4 mm long with a screw head diameter of 7–9 mm, screwed into wood to an optimal depth leaving approximately 5.5 mm of the screw exposed. Align the slots on the back of the charger with the exposed screws and fully engage them in the slots.

Charger Cleaning Instructions
WARNING: Shock hazard. Disconnect the charger from the AC outlet before cleaning. Dirt and grease may be removed from the exterior of the charger using a cloth or soft non-metallic brush. Do not use water or any cleaning solutions. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.

• WARNING: Burn hazard. Battery liquid may be flammable if exposed to spark or flame.

• WARNING: Never attempt to open the battery pack for any reason. If the battery pack case is cracked or damaged, do not insert into the charger. Do not crush, drop or damage the battery pack. Do not use a battery pack or charger that has received a sharp blow, been dropped, run over or damaged in any way (i.e., pierced with a nail, hit with a hammer, stepped on). Electric shock or electrocution may result. Damaged battery packs should be returned to a service center for recycling.

• WARNING: Fire hazard. Do not store or carry the battery pack so that metal objects can contact exposed battery terminals. For example, do not place the battery pack in aprons, pockets, tool boxes, product kit boxes, drawers, etc., with loose nails, screws, keys, etc.

• CAUTION: When not in use, place tool on its side on a stable surface where it will not cause a tripping or falling hazard. Some tools with large battery packs will stand upright on the battery pack but may be easily knocked over.

Transportation

WARNING: Fire hazard. Transporting batteries can possibly cause fire if the battery terminals inadvertently come in contact with conductive materials. When transporting batteries, make sure that the battery terminals are protected and well insulated from materials that could contact them and cause a short circuit. NOTE: Lithium-ion batteries should not be put in checked baggage.

DEWALT batteries comply with all applicable shipping regulations as prescribed by industry and legal standards which include UN Recommendations on the Transport of Dangerous Goods; International Air Transport Association (IATA) Dangerous Goods Regulations, International Maritime Dangerous Goods (IMDG) Regulations, and the European Agreement Concerning The International Carriage of Dangerous Goods by Road
(ADR). Lithium-ion cells and batteries have been tested to section 38.3 of the UN Recommendations on the Transport of Dangerous Goods Manual of Tests and Criteria.

In most instances, shipping a DEWALT battery pack will be excepted from being classified as a fully regulated Class 9 Hazardous Material. In general, only shipments containing a lithium-ion battery with an energy rating greater than 100 Watt Hours (Wh) will require being shipped as fully regulated Class 9. All lithium-ion batteries have the Watt Hour rating marked on the pack. Furthermore, due to regulation complexities, DEWALT does not recommend air shipping lithium-ion battery packs alone regardless of Watt Hour rating. Shipments of tools with batteries (combo kits) can be air shipped as excepted if the Watt Hour rating of the battery pack is no greater than 100 Wh. Regardless of whether a shipment is considered excepted or fully regulated, it is the shipper’s responsibility to consult the latest regulations for packaging, labeling/marking and documentation requirements.
The information provided in this section of the manual is provided in good faith and believed to be accurate at the time the document was created. However, no warranty, expressed or implied, is given. It is the buyer’s responsibility to ensure that its activities comply with the applicable regulations.

Transporting the FLEXVOLTTM Battery
The DEWALT FLEXVOLTTM battery has two modes:

Use and Transport.

• Use Mode: When the FLEXVOLTTM battery stands alone or is in a DEWALT 18V product, it will operate as an 18V battery. When the FLEXVOLTTM battery is in a 54V or a 108V (two 54V batteries) product, it will operate as a 54V battery.
• Transport Mode: When the cap is attached to the FLEXVOLTTM battery, the battery is in Transport mode. Keep the cap for shipping. When in Transport mode, strings of cells are electrically disconnected within the pack resulting in 3 batteries with a lower Watt-hour (Wh) rating as compared to 1 battery with a higher Watt hour rating. This increased quantity of 3 batteries with the lower Watt hour rating can exempt the pack from certain shipping regulations that are imposed upon the higher Watt hour batteries. For example, the Transport Example of Use and Transport Label Marking Wh rating might indicate 3 x 36 Wh, meaning 3 batteries of 36 Wh each. The Use Wh rating might indicate 108 Wh (1 battery implied).

Storage Recommendations

1. The best storage place is one that is cool and dry away from direct sunlight and excess heat or cold. For optimum battery performance and life, store battery packs at room temperature when not in use.
2. For long storage, it is recommended to store a fully charged battery pack in a cool, dry place out of the charger for optimal results.
   NOTE: Battery packs should not be stored completely depleted of charge. The battery pack will need to be recharged before use.

Labels on Charger and Battery Pack
In addition to the pictographs used in this manual, the labels on the charger and the battery pack may show the following pictographs:

• Read the instruction manual before use.
• See Technical Data for charging time.
• Do not probe with conductive objects.
• Do not charge damaged battery packs.

Inserting and Removing the Battery Pack from the Tool (Fig. B)
NOTE: Make sure your battery pack  8  is fully charged.

To Install the Battery Pack into the Tool Handle

1. Align the battery pack with the rails inside the tool’s handle (Fig. B).
2. Slide it into the handle until the battery pack is firmly seated in the tool and ensure that you hear the lock snap into place.

To Remove the Battery Pack from the Tool

1. Press the battery release button  9  and firmly pull the battery pack out of the tool handle.
2. Insert battery pack into the charger as described in the charger section of this manual.

Fuel Gauge Battery Packs (Fig. B)
Some DEWALT battery packs include a fuel gauge which consists of three green LED lights that indicate the level of charge remaining in the battery pack.
To actuate the fuel gauge, press and hold the fuel gauge button  14 . A combination of the three green LED lights will illuminate designating the level of charge left. When the level of charge in the battery is below the usable limit, the fuel gauge will not illuminate and the battery will need to be recharged. NOTE: The fuel gauge is only an indication of the charge left on the battery pack. It does not indicate tool functionality and is subject to variation based on product components, temperature and end-user application.

Electronic Overload Protection
If the drill bit becomes jammed, the power to the drill spindle will be interrupted by the activation of the electronic overload protection. To reactivate the power to the drive spindle, the tool’s trigger should be released and then depressed. Due to the resulting forces, always hold the tool with both hands and take a firm stance.

Active Vibration Control (Fig. A)
For best vibration control, hold the tool with one hand on the main handle  6 and the other hand on the side handle  1 . Apply just enough pressure so the Active Vibration Control  10  in the rear handle are halfway depressed. The hammer only needs enough pressure to engage the internal active vibration control. Applying too much pressure will not make the tool drill faster and active vibration control will not engage.
