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.
- Work Area Safety
-
* Keep work area clean and well lit. Cluttered or 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 children and bystanders away while operating a power tool. Distractions can cause you to lose control.
-
Electrical Safety
-
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.
-
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.
-
Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
-
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.
-
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.
-
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
-

-
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.
-
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.
-
Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power tool in unexpected situations. -
Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
-
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.
-
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.
Power Tool Use and Care
- 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.
- 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.
- 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.
- 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.
- 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.
- Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
- 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.
- Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping do not allow for safe handling and control of the tool in unexpected situations.

- 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 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)
NOTE: To ensure maximum performance and life of lithium‑ion battery
packs, charge the battery pack fully before first use.
- Plug the charger into an appropriate outlet before inserting battery pack.
- Insert the battery pack 11 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.
- The Stage 1 charging blink indicator represents the charge process that charges the majority of the battery’s capacity. Stage 2 charging blink indicator represents the remainder, or top off charge process, for the battery to reach full capacity.
- The completion of charge for Stage 1 or Stage 2 will be indicated by the stage’s light remaining ON continuously. The battery pack is fully charged when both Stage 1 and Stage 2 charging lights remain ON continuously, and it may be removed and used at this time or left in the charger.
NOTE: To remove the battery pack, some chargers require the battery pack release button 12 to be pressed. 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 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 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.

outlined.
READ ALL INSTRUCTIONS
- Do not charge or use battery in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Inserting or removing the battery from the charger may ignite the dust or fumes.
- Never force battery pack into charger. Do not modify battery pack in any way to fit into a non‑compatible charger as battery pack may rupture, causing serious personal injury.
- Charge the battery packs only in DEWALT chargers.
- DO NOT splash or immerse in water or other liquids.
- Do not store or use the tool and battery pack in locations where the temperature may fall below 4 ˚C (39.2 ˚F) (such as outside sheds or metal buildings in winter), or reach or exceed 40 ˚C (104 ˚F) (such as outside sheds or metal buildings in summer).
- Do not incinerate the battery pack even if it is severely damaged or is completely worn out. The battery pack can explode in a fire. Toxic fumes and materials are created when lithium‑ion battery packs are burned.
- If battery contents come into contact with the skin, immediately wash area with mild soap and water. If battery liquid gets into the eye, rinse water over the open eye for 15 minutes or until irritation ceases. If medical attention is needed, the battery electrolyte is composed of a mixture of liquid organic carbonates and lithium salts.
- Contents of opened battery cells may cause respiratory irritation. Provide fresh air. If symptoms persist, seek medical attention.
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
battery pack case is cracked or damaged, do not insert into charger. Do not
crush, drop or damage 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 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 into 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 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 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 Wh rating marked on the pack. Furthermore, due
to regulation complexities, DeWALT does not recommend air shipping lithium‑ion
battery packs alone regardless of Wh rating. Shipments of tools with batteries
(combo kits) can be air shipped as excepted if the Wh 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
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
FLEXVOLT® 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
- The best storage place is one that is cool and dry away from direct sunlight and excessive 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.
