WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or seriousinjury.

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

a ) Keep work area clean and well lit. Cluttered or dark areas inviteaccidents. 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 orfumes. c ) Keep children and bystanders away while operating a power tool. Distractions can cause you to losecontrol.

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 electricshock. 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 orgrounded. c ) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electricshock. 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 electricshock. 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 electricshock. f ) If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electricshock.

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 personalinjury. 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 personalinjuries. 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 invitesaccidents. 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 personalinjury. e ) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpectedsituations. f ) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in movingparts. 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-relatedhazards.

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 wasdesigned. 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 berepaired. 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 toolaccidentally. 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 untrainedusers. 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 powertools. f ) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier tocontrol. g ) Use the power tool, accessories and tool bits, etc. in accordance with these instructions, takingENGLISH

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 hazardoussituation.

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 batterypack. b ) Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury andfire. 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 afire. 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 orburns.

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 ismaintained. Nailer Safety Warnings

• Always assume that the tool contains fasteners. Careless handling of the nailer can result in unexpected firing of fasteners and personalinjury.

• Do not point the tool towards yourself or anyone nearby. Unexpected triggering will discharge a fastener causing aninjury.

• 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 yourtarget.

• 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 pluggedin.

• 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 firehazards. Additional Nailer Safety Warnings

WARNING: When using any nailer, all safety

precautions, as outlined below, should be followed to avoid the risk of death or serious injury. Read and understand all instructions before operating thetool.

lubricants or cleaning solvents inside the tool. This can seriously affect the life and performance of thetool.

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

• 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.

• Hold tool by insulated gripping surfaces when performing an operation where the fastener may contact hidden wiring. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock theoperator.

• Actuating tool may result in flying debris, collation material, or dust which could harm operator’s eyes. Operator and others in work area MUST wear safety glasses with side shields. These safety glasses must conform to ANSI Z87.1 requirements (approved glasses have “Z87” printed or stamped on them. It is the employer’s responsibility to enforce the use of eye protection equipment by the tool operator and other people in the workarea.

• Always wear appropriate personal hearing and other protection during use. Under some conditions and duration of use, noise from this product may contribute to hearingloss.

• Disconnect battery pack from the tool when not in use. Always remove battery pack and remove fasteners from magazine before leaving the area or passing the tool to another operator. Do not carry tool to another work area in which changing location involves the use of scaffoldings, stairs, ladders, and the like, with battery pack connected. Do not make adjustments, perform maintenance or clear jammed fasteners while battery is inplace.

• Do not remove, tamper with, or otherwise cause the tool, trigger or trigger lock-off, to become inoperable. Do not tape or tie trigger in the on position. Do not remove spring from contact trip. Make daily inspections for free movement of trigger. Uncontrolled discharge couldresult.

• Inspect tool before use. Do not operate a tool if any portion of the tool, trigger, or trigger lock-off is inoperable, disconnected, altered, or not working properly. Damaged parts or missing parts should be repaired or replaced before use. Refer toRepairs.

• Do not alter or modify the tool in anyway.

• Always assume that the tool containsfasteners.

• Do not point the tool at co-workers or yourself at any time. No horseplay! Work safe! Respect the tool as a workingimplement.

• Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you toENGLISH

lose control. When tool is not in use, it should be locked in a safe place, out of the reach ofchildren.

• Always use trigger lock-off when tool is not in immediate use. Using the trigger lock-off will prevent accidentaldischarge.

• Do not overreach. Maintain proper footing and balance at all times. Loss of balance may cause personalinjury.

• Use the tool only for its intended use. Do not discharge fasteners into open air, concrete, stone, extremely hard woods, knots or any material too hard for the fastener to penetrate. Do not use the body of the tool or top cap as a hammer. Discharged fastener may follow unexpected path and causeinjury.

• Always keep fingers clear of contact trip to prevent injury from inadvertent release of thepusher.

• Refer to the Maintenance and Repairs sections for detailed information on the proper maintenance of thetool.

• Always operate the tool in a clean, lighted area. Be sure the work surface is clear of any debris and be careful not to lose footing when working in elevated environments such asrooftops.

• Do not drive fastener near edge of material. The workpiece may split causing the nail to ricochet, injuring you or a co-worker. Be aware that the fastener may follow the grain of the wood (shiner), causing it to protrude unexpectedly from the side of the work material. Drive the chisel point of the fastener perpendicular to the grain to reduce risk ofinjury.

• Do not drive nails onto the heads of other fasteners or with the tool at too steep an angle. Personal injury from strong recoil jammed nails, or ricocheted nails mayresult.

• Keep hands and body parts clear of immediate work area. Hold workpiece with clamps when necessary to keep hands and body out of potential harm. Be sure the workpiece is properly secured before pressing the nailer against the material. The contact trip may cause the work material to shiftunexpectedly.

• Do not use tool in the presence of flammable dust, gases or fumes. The tool may produce a spark that could ignite gases causing a fire. Driving a nail into another nail may also cause aspark.

• Keep face and body parts away from back of the tool cap when working in restricted areas. Sudden recoil can result in impact to the body, especially when nailing into hard or densematerial.

• Grip tool firmly to maintain control while allowing tool to recoil away from work surface as fastener is driven. In Bump mode if contact trip is allowed to recontact work surface before trigger is released an unwanted fastener will befired.

• Choice of triggering method is important. Check the manual for triggeringoptions.

• Always select an actuation system that is appropriate to the fastener application and the training of theoperator.

• Use caution when handling, loading or unloading fasteners. Fasteners have sharp points which could causeinjury.

• Only wear gloves that provide adequate feel and safe control of the trigger and any adjustingdevices. Bump/Sequential Selector Switch Sequential Action

• When using the tool in sequential action, do not actuate the tool unless the tool is placed firmly against theworkpiece. Bump Action

• When using the tool in bump action, be careful of unin tentional double fires resulting from tool recoil. Unwanted fasteners may be driven if the contact trip is allowed to accidentally re-contact the worksurface.

• To Avoid Double Fires: ʵ Do not engage the tool against the work surface with a strongforce. ʵ Allow the tool to recoil fully after eachactuation. ʵ Use sequential actionmode.

• When bump actuating the framing nailer, always keep tool in control. Inaccurate placement of tool can result in misdirected discharge of anail.

• Be aware of material thickness when using nailer. A protruding nail may causeinjury.

• Depth adjustment: To reduce risk of serious injury from accidental actuation when attempting to adjust depth, ALWAYS; ʵ Remove batterypack. ʵ Engage trigger lock-off. ʵ Avoid contact with trigger during adjustments

• Do not drive nails blindly into walls, floors or other work areas. Fasteners driven into live electrical wires, plumbing, or other types of obstructions can result in injury and or propertydamage.

• Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personalinjury. Additional Safety Information

Shipping the DeWALT FLEXVOLT™ Battery The D

WALT FLEXVOLT™ battery has two modes: Use and Shipping. Use Mode: When the FLEXVOLT™ battery stands alone or is in a D

WALT 20V Max* product, it will operate as a 20V Max* battery. When the FLEXVOLT™ battery is in a 60V Max* or a 120V Max* (two 60V Max* batteries) product, it will operate as a 60V Max* battery. Shipping Mode: When the cap is attached to the FLEXVOLT™ battery, the battery is in Shipping Mode. Strings of cells are electrically disconnected within the pack resulting in three batteries with a lower Watt hour (Wh) rating as compared to one battery with a higher Watt hour rating. This increased quantity of three batteries with the lower Watt hour rating can exempt the pack from certain shipping regulations that are imposed upon the higher Watt hourbatteries. The battery label indicates two Watt hour ratings (see example). Depending on how the battery is shipped, the appropriate Watt hour rating must be used to determine the applicable shipping requirements. If utilizing the shipping cap, the pack will be considered 3 batteries at the Watt hour rating indicated for “Shipping”. If shipping without the cap or in a tool, the pack will be considered one battery at the Watt hour rating indicated next to “Use”. USE: 120 Wh Shipping: 3 x 40 Wh Example of Use and Shipping Label Marking For example, Shipping Wh rating might indicate 3 x 40 Wh, meaning 3 batteries of 40 Watt hours each. The Use Wh rating might indicate 120 Wh (1 batteryimplied).

Charging Fully Charged Hot/Cold Pack Delay** ** DCB107, DCB112, DCB113, DCB115, DCB118, DCB132: 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 chargingprocedure. The compatible charger(s) will not charge a faulty battery pack. The charger will indicate faulty battery pack by refusing tolight. NOTE: This could also mean a problem with acharger. If the charger indicates a problem, take the charger and battery pack to be tested at an authorized servicecenter. 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 packlife. 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 packwarms. 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 becooled. 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 thecharger. Electronic Protection System Li-Ion tools are designed with an Electronic Protection System that will protect the battery pack against overloading, overheating or deepdischarge. 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 fullycharged. Wall Mounting

DCB107, DCB112, DCB113, DCB115, DCB118, DCB132

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 1" (25.4 mm) long, with a screw head diameter of 0.28–0.35" (7–9mm), screwed into wood to an optimal depth leaving approximately 7/32" (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 theslots. 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 cleaningsolutions. Important Charging Notes

1. Longest life and best performance can be obtained if

the battery pack is charged when the air temperature is between 65°F and 75°F (18° – 24°C). DO NOT charge the battery pack below +40°F (+4.5°C), or above +104°F (+40°C). This is important and will prevent serious damage to the batterypack.

2. The charger and battery pack may become warm to the

touch while charging. This is a normal condition, and does not indicate a problem. To facilitate the cooling of the battery pack after use, avoid placing the charger or battery pack in a warm environment such as in a metal shed or an uninsulatedtrailer.

3. If the battery pack does not charge properly:

a. Check operation of receptacle by plugging in a lamp or other appliance;English
