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.

SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE

The term “power tool” in the warnings refers to your mainsoperated (corded) power tool or battery-operated (cordless) power tool.

Work area safety

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.
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.
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.
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.
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.
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.
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 handles 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.
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.
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.
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.

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

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 by a specially prepared cord available through the DeWALT service organisation.

Fully Charged
Hot/Cold Pack Delay*

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 faulty battery 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.

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 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 air flow. 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.

Electric shock or electrocution may result. Damaged battery packs should be returned to service centre 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. 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 Whr. 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 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).

Example of Use and Transport Label Marking

Storage Recommendations

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.
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.

Operation Modes (Fig. A, E)

WARNING: Do not select the operating mode when the tool is running.
Your tool is equipped with a mode selector dial 5 to select the mode appropriate to desired operation.

symbol	Mode	application
Rotary Drilling	Dry diamond coring
Rotary Hammering	Drilling into concrete and

masonry
| Hammering only| Light chipping

To select an operating mode:

Depress the mode selector release button 6 .
Rotate the mode selector dial so that the arrow points to the symbol corresponding with the desired mode.

NOTE: The mode selector 5 must be in rotary drilling, rotary hammering or hammering only mode at all times. There are no operable positions in between. It may be necessary to briefly run the motor after having changed from ‘hammering only’ to ‘rotary’ modes in order to align the gears.

Performing an Application (Fig. A, F)

WARNING: TO REDUCE THE RISK OF PERSONAL INJURY, ALWAYS ensure workpiece is anchored or clamped firmly. If drilling thin material, use a wood “backup” block to prevent damage to the material.
WARNING: Always wait until the motor has come to a complete standstill before changing the direction of rotation.

Choose and install the appropriate chuck, adapter, and/or bit onto to the tool. Refer to Bit and Bit Holders.
Using the mode selector dial 5 , select the mode appropriate to desired application. Refer to Operation Modes.
Adjust the side handle 3 as required.
Place the bit/chisel on the desired location.
Depress the trigger switch 4 .

NOTE: Depending on your tool, depressing the trigger switch activates a worklight 10 designed to illuminate the immediate work surface. Refer to Description. The worklight will automatically turn off 20 seconds after the trigger switch is released.

Recommendations for Tool Operation

When drilling, always apply pressure in a straight line with the bit, but do not push hard enough to stall the motor or deflect the bit. A smooth even flow of material indicates the proper drilling rate.
Your hammer can be used for dry diamond drilling into masonry up to 100 mm. For diamond drilling above this diameter in masonry and regular large diameter diamond drilling in masonry and concrete, we advise the use of a dedicated diamond core drill. Follow the core bit or manufacturer’s recommendations for using the accessory.
NOTE: Always use core bits with integral centredrill systems and ensure the RPM (speed) of the hammer does not exceed the maximum rated RPM of the diamond core.
- Insert the centredrill into its holder in the centre of the core bit.
- Remove and unplug the machine.
- Remove the centredrill from its holder.
- Plug the machine in and insert the core bit into the workpiece.
