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

2. Keep work area clean and well lit. Cluttered or dark areas invite accidents.

3. 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.

4. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

5. Electrical Safety

6. 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 the risk of electric shock.

7. 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.

8. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

9. 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.

10. 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.

11. Personal Safety

12. 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.

13. 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.

14. 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.

15. 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.

16. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

17. 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.

18. 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.

19. 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.

20. Power Tool Use and Care

21. 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.

22. 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.

23. 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.

24. 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.

25. 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.

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

27. 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.

28. 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.

29. Battery Tool Use and Care

30. 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.

31. Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.

32. 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.

33. 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.

34. Do not use a battery pack or tool that is damaged  or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.

35. Do not expose a battery pack or tool to fire or
    excessive temperature. Exposure to fire or temperature above 130 °C may cause an explosion.

36. Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

37. Service

38. 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.

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

Safety Instructions for Cordless Nailers

• Always assume that the tool contains fasteners. Careless handling of the nailer can result in unexpected firing of fasteners and personal injury.
• Do not point the tool towards yourself or anyone nearby. Unexpected triggering will discharge the fastener causing an injury.
• Do not actuate the tool unless the tool is placed firmly against the workpiece. If the tool is not in contact with the workpiece, the fastener may be deflected away from your target.
• Keep hands and body parts away from the discharge area of the tool. While in use NEVER grasp the tool by the magazine or canister, a mis‑driven nail can exit the nose causing injury.
• Disconnect the tool from the power source when the fastener jams in the tool. While removing a jammed fastener, the nailer may be accidentally activated if it is plugged in.
• Do not use this nailer for fastening electrical cables. It is not designed for electric cable installation and may damage the insulation of electric cables thereby causing electric shock or fire hazards.
  • WARNING: If the tool has been dropped or you suspect tool damage perform tool operation check as defined in the mode selection section of the manual. If it doesn’t perform according to the manual, stop using the tool and have it serviced at an authorized DEWALT service centre.
• Always wear safety glasses.
• Always wear ear protection.
• Only use fasteners of the type specified in the manual.
• Do not use any stands for mounting the tool to a support.
• Do not disassemble or block any parts of the fastener driving tool such as the contact trip.
• Prior to each operation check that the safety and triggering mechanism is functioning properly and that all nuts and bolts are tight.
• Do not use the DCN45RN
  • when changing from one driving location to another involving the use of scaffoldings, stairs, ladders or ladder‑like constructions, e.g., roof laths, etc.;
  • when closing boxes or crates;
  • when fitting transportation safety systems, e.g., on vehicles, wagons, etc.For exemptions check your local national workplace regulations.
• Always check local workplace regulations.
• Do not use the tool as a hammer.
• Never actuate the fastener driving tool into free space.
• In the work area, carry the tool at the workplace using only one hand, and never with the trigger actuated.
• Consider the conditions in the work area. Fasteners can penetrate thin workpieces or slip off corners and edges of the work piece, and thus put people at risk.
• Do not drive fasteners close to the edge of the workpiece.
• Do not drive fasteners on top of other fasteners.

Residual Risks
The following risks are inherent to the use of these machines:

• Injuries caused by improper handling of the tool.
• Loss of control due to not gripping tool firmly.
• Muscle strain of arms and hands, especially when working overhead. Always take regular breaks when working for long periods of time.

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.
• Loss of control caused by recoil.
• Risk of injury caused by pinch points, sharp edges and improper handling of workpiece.
• Risk of injury caused by sharp edges when changing nails or inserting nail sticks.

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

Charging a Battery (Fig. B)

1. Plug the charger into an appropriate outlet before inserting battery pack.
2. Insert the battery pack  1  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  2  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.

Charge Indicators

• Charging

• 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.

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.

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 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 indicate3 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.

6. Keep tool pointed away from yourself and others.
7. Insert fully charged battery pack.

Using the Trigger Lock‑Off (Fig. D)
Each DEWALT nailer is equipped with a trigger lock-off  4  which when pushed to the right as shown in Figure D, prevents the tool from firing a nail by locking the trigger and bypassing power to the motor. When the trigger lock- off is pressed to the left, the tool will be fully operational. The trigger lock-off should always be locked off whenever any adjustments are made or when tool is not in immediate use.
Loading the Tool (Fig. E–G) WARNING: Keep the tool pointed away from yourself and others.
WARNING: Never load nails with the contact trip or trigger activated.
WARNING: Always remove battery pack before loading or unloading nails.
CAUTION: Keep fingers clear of pusher latch track to prevent injury.

WARNING: The trigger lock‑off should always be engaged whenever any adjustments are made or when tool is not in use.

1. Push the door latch  13  to open the nail door  8 .

2. Rotate the canister cover  6  open.

3. Adjust the nail platform  15  according to the length of nails being used.

4. Swing the nail platform out and move it along the rail to it set for one of three postions.

5.  Move the nail platform back into position making sure the tab  16  its securely into one of the three numbered slots.

6. Nail platform          Nail length

7. Position 1          22 mm

8. Position 2          25 mm–33 mm

9. Position 3          38 mm–45 mm

10. Place the coil on the nail platform. Insert fasteners with points down. IMPORTANT: Fasteners must point in the same direction as they will be driven.

11. Uncoil enough nails (approximately 76 mm) to reach the nose of the tool.

12. Insert the first nail into the nose and the second nail between the two rails of the feed pawl.
    NOTE: Be careful not to deform the coil of nails during the loading process. Otherwise, the nail door will not close and the nails might not feed consistently.

13. Close the nail door making sure the door latch is completely engaged.

WARNING: The trigger lock‑off should always be locked off whenever any adjustments are made or when tool is not in use.

1. Push the door latch  13  to open the nailed door  8.
2. Rotate the canister cover  6  open.
3. Remove the coil from the nail platform.

Adjusting Depth (Fig.k. H)
The depth that the nail is driven can be adjusted using the depth adjustment wheel  3  on the nose of the tool.

WARNING: To reduce risk of serious injury from accidental actuation when attempting to adjust depth, ALWAYS:

• Remove battery pack.
• Engage trigger lock‑off.
• Always point the nose of the nailer away from you.
• Avoid contact with trigger during adjustments.

The depth that the fastener is driven can be adjusted using the depth adjustment wheel  5  on the nose of the tool. The depth of drive is factory adjusted to a nominal setting. Test fire a fastener and check depth. If a change is desired:

1. To drive the nail deeper, rotate the depth adjustment wheel to the right. Setting 5 is the deepest.
2. To drive a nail shallower, rotate the depth adjustment wheel to the left. Setting 1 is the shallowest.

Test drive another fastener and check depth. Repeat as necessary to achieve desired results.
Stall Release (Fig. I)
If the nailer is used in rigorous application where all available energy in the motor is used to drive a fastener, the tool may stall. The driver blade did not complete the drive cycle and the jam/stall indicator will flash. Rotate the stall release lever  14  on the tool and the mechanism will release. If the driver blade does not automatically return to the home position, proceed to Clearing a Jammed Nail. If the unit continues to stall please review the mode selection, material and fastener length to be sure that it is not too rigorous an application.
If continuous stalling occurs, review speed selection. Depending upon the application, a different speed setting may be necessary.

Clearing a Jammed Nail (Fig. A, E–G)
If a nail becomes jammed in the nosepiece, keep the tool pointed away from you and follow these instructions to clear: NOTE: The jam could be as a result of debris build up in the nose channel. Please check and clear out any debris as outlined below immediately if you notice any change of performance in the tool.

1. Remove battery pack from tool and engage trigger lock-off.
2. Push the door latch  13  to open the nail door  8

WARNING: The declared vibration and/or noise emission level represents the main applications of the tool. However if the tool is used for different applications, with different accessories or poorly maintained, the vibration and/or noise emission may differ. This may significantly increase the exposure level over the total working period.
An estimation of the level of exposure to vibration and/or noise should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the effects of vibration and/or noise such as: maintain the tool and the accessories, keep the hands warm (relevant for vibration), organization of work patterns.

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