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 cause injury.
Always keep fingers clear of contact trip to prevent injury from inadvertent release of
the pusher.
Refer to the Maintenance and Repairs sections for detailed information on the proper
maintenance of the tool.
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
as rooftops.
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 of injury.
Fasteners must be driven straight into the material. Do not tilt nailer while driving
fasteners. Personal injury from strong recoil jammed nails, or ricocheted nails may result.
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 shift unexpectedly.

WARNING: Keep hands away from area in front of tool.
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
a spark.
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
dense material.
Grip tool firmly to maintain control while allowing tool to recoil away from work
surface as fastener is driven.
Be aware of material thickness when using nailer. A protruding nail may cause injury.
DEPTH ADJUSTMENT: To reduce risk of serious injury from accidental actuation when
attempting to adjust depth, ALWAYS;
ʵ Remove battery pack.
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.
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 personal injury.

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 D
WALT Service Center.

Additional Safety Information

WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses.
Also use face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED
SAFETY EQUIPMENT:
ANSI Z87.1 eye protection (CAN/CSA Z94.3),
ANSI S12.6 (S3.19) hearing protection,
NIOSH/OSHA/MSHA respiratory protection.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to the State of California to cause cancer,
birth defects or other reproductive harm. Some examples of these chemicals are:
lead from lead-based paints,
crystalline silica from bricks and cement and other masonry products, and
arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well ventilated area, and work with approved safety
equipment, such as those dust masks that are specially designed to filter out microscopic particles.
Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and
other construction activities. Wear protective clothing and wash exposed areas with
soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote
absorption of harmful chemicals.

WARNING: Use of this tool can generate and/or disperse dust, which may cause serious
and permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory
protection appropriate for the dust exposure. Direct particles away from face and body.

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.
Air vents often cover moving parts and should be avoided. Loose clothes, jewelry or long
hair can be caught in moving parts.

BATTERIES AND CHARGERS
The battery pack is not fully charged out of the carton. Before using the battery pack and charger,
read the safety instructions below and then follow charging procedures outlined. When ordering
replacement battery packs, be sure to include the catalog number and voltage.
Your tool uses a D
WALT charger. Be sure to read all safety instructions before using your charger.

Consult the chart at the end of this manual for compatibility of chargers and battery packs.
READ ALL INSTRUCTIONS
Important Safety Instructions for All Battery Packs

WARNING: Read all safety warnings and all instructions for the battery pack,
charger and power tool. Failure to follow the warnings and instructions may result
in electric shock, fire and/or serious injury.
Do not charge or use the battery pack in explosive atmospheres, such as in the presence
of flammable liquids, gases or dust. Inserting or removing the battery pack from the charger
may ignite the dust or fumes.
NEVER force the battery pack into the charger. DO NOT modify the battery pack in any
way to fit into a non-compatible charger as battery pack may rupture causing serious
personal injury. Consult the chart at the end of this manual for compatibility of batteries
and chargers.
Charge the battery packs only in designated D
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
reach or exceed 104 °F (40 °C) (such as outside sheds or metal buildings in summer). For
best life store battery packs in a cool, dry location.
NOTE: Do not store the battery packs in a tool with the trigger switch locked on. Never
tape the trigger switch in the ON position.
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: Fire hazard. 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 (e.g., pierced with a nail, hit with
a hammer, stepped on). Damaged battery packs should be returned to the service center
for recycling.
Transportation

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. Transporting batteries can possibly cause fires if the battery terminals
inadvertently come in contact with conductive materials such as keys, coins, hand
tools and the like. The US Department of Transportation Hazardous Material Regulations
(HMR) actually prohibit transporting batteries in commerce or on airplanes in carry-on
baggage UNLESS they are properly protected from short circuits. So when transporting
individual battery packs, make sure that the battery terminals are protected and well
insulated from materials that could contact them and cause a short circuit.
