General Safety Rules – For All Battery Operated Tools
WARNING! Read and understand all instructions. Failure to follow all instructions listed
below may result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
WORK AREA
• Keep your work area clean and well lit. Cluttered benches and 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 bystanders, children, and visitors away while operating a power tool. Distractions
can cause you to lose control.
ELECTRICAL SAFETY
• Do not abuse the cord. Never use the cord to carry the tool. Keep cord away from heat,
oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords
may create a fire.
• A battery operated tool with integral batteries or a separate battery pack must be
recharged only with the specified charger for the battery. A charger that may be suitable
for one type of battery may create a risk of fire when used with another battery.
• Use battery operated tool only with the specifically designated battery pack. Use of any
other batteries may create a risk of fire.
PERSONAL SAFETY
• 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,
• Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair,
clothing, and gloves away from moving parts. Loose clothing, jewelry, or long hair can be
caught in moving parts. Air vents often cover moving parts and should also be avoided.
• Avoid accidental starting. Be sure switch is in the locked or off position before inserting
battery pack. Carrying tools with your finger on the switch or inserting the battery pack into a
tool with the switch on invites accidents.
• Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that is
left attached to a rotating part of the tool may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. Proper footing and
balance enables better control of the tool in unexpected situations.
• Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes,
hard hat, or hearing protection must be used for appropriate conditions.
TOOL USE AND CARE
• 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 a loss
of control.
• Do not force tool. Use the correct tool for your application. The correct tool will do the job
better and safer at the rate for which it is designed.
• Do not use tool if switch does not turn it on or off. A tool that cannot be controlled with the
switch is dangerous and must be repaired.
• Disconnect battery pack from tool or place the switch in the locked or off position
before making any adjustments, changing accessories, or storing the tool. Such
preventative safety measures reduce the risk of starting the tool accidentally.
• Store idle tools out of reach of children and other untrained persons. Tools are
dangerous in the hands of untrained users.
• 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 sparks, burns,
or a fire.
• Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools,
with sharp cutting edges are less likely to bind and are easier to control.
• Check for misalignment or binding of moving parts, breakage of parts, and any other
condition that may affect the tool’s operation. If damaged, have the tool serviced before
using. Many accidents are caused by poorly maintained tools.
• Use only accessories that are recommended by the manufacturer for your model.
Accessories that may be suitable for one tool, may create a risk of injury when used on another
tool.
SERVICE
• Tool service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel may result in a risk of injury.
• When servicing a tool, use only identical replacement parts. Follow instructions in the
Maintenance section of this manual. Use of unauthorized parts or failure to follow
Maintenance Instructions may create a risk of shock or injury.
Additional Safety Rules
• Hold tool by insulated gripping surfaces when performing an operation where the tool
may contact hidden wiring. Contact with a “live” wire will also make exposed metal parts of
the tool “live” and shock the operator.
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.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other con-
struction activities contains chemicals known to cause cancer, birth defects or other reproduc-
tive 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 (CCA).
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.
• The label on your tool may include the following symbols.The symbols and their definitions are
as follows:
V ..................volts
A ....................amperes
Hz ................hertz
W ....................watts
min ..............minutes

Important Safety Instructions for Battery Packs
Your tool uses a 12.0 volt, 14.4 volt, or an 18 volt D
WALT battery Pack. When ordering
E
replacement battery packs, be sure to include catalog number and voltage. Extended Run-Time
battery packs deliver more run-time than standard battery packs. Consult the chart at the end
of this manual for compatibility of chargers and battery packs.
NOTE: Your tool will accept either standard or Extended Run Time battery packs. However, be
sure to select proper voltage. Batteries slowly lose their charge when they are not on the
charger, the best place to keep your battery is on the charger at all times.
The battery pack is not fully charged out of the carton. Before using the battery pack and
charger, read the safety instructions below. Then follow charging procedures outlined.
READ ALL INSTRUCTIONS
• 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.
• A small leakage of liquid from the battery pack cells may occur under extreme usage
or temperature conditions. This does not indicate a failure.
However, if the outer seal is broken:
a. and the battery liquid gets on your skin, immediately wash with soap and water for
several minutes.
b. and the battery liquid gets into your eyes, flush them with clean water for a minimum of
10 minutes and seek immediate medical attention. (Medical note: The liquid is 25-35%
solution of potassium hydroxide.)
• Charge the battery packs only in D
WALT chargers.
E
• 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 105°F (40˚) (such as outside sheds or metal buildings in summer).
DANGER: Electrocution hazard. Never attempt to open the battery pack for any reason. If
battery pack case is cracked or damaged, do not insert into charger. Electric shock or
electrocution may result. Damaged battery packs should be returned to service center for
recycling.
NOTE: Battery storage and carrying caps are provided for use whenever the battery
is out of the tool or charger. Remove cap before placing battery in charger or tool.
WARNING: Fire hazard. Do not store or carry battery so that metal objects
can contact exposed battery terminals. For example, do not place battery in
aprons, pockets, tool boxes, product kit boxes, drawers, etc., with loose nails, screws,
keys, etc. without battery cap. 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 (i.e.,
packed in suitcases and carry-on luggage) UNLESS they are properly protected from short
circuits. So when transporting individual batteries, make sure that the battery terminals are
protected and well insulated from materials that could contact them and cause a short circuit.
CAUTION: Battery pack must be securely attached to tool. If battery pack is detached,
personal injury may result.
The RBRC™ Seal
The RBRC™ (Rechargeable Battery Recycling Corporation) Seal on the nickel
cadmium and nickel metal hydride batteries (or battery packs) indicate that the costs
to recycle these batteries (or battery packs) at the end of their useful life have already
been paid by D
WALT. In some areas, it is illegal to place spent nickel
E
cadmium and nickel metal hydride batteries in the trash or municipal solid waste
stream and the RBRC program provides an environmentally conscious alternative.
RBRC™ in cooperation with D
WALT and other battery users, has established programs in the
E
United States and Canada to facilitate the collection of spent nickel cadmium and nickel metal
hydride batteries. Help protect our environment and conserve natural resources by returning the
spent nickel cadmium and nickel metal hydride batteries to an authorized D
WALT service center
E
or to your local retailer for recycling. You may also contact your local recycling center for
information on where to drop off the spent battery.
RBRC™ is a registered trademark of the Rechargeable Battery Recycling Corporation.
Important Safety Instructions for Battery Chargers
SAVE THESE INSTRUCTIONS: This manual contains important safety instructions for battery
chargers.
• Before using charger, read all instructions and cautionary markings on charger, battery pack,
and product using battery pack.
DANGER: Electrocution hazard. 120 volts are present at charging terminals. Do not probe with
conductive objects.
WARNING: Shock hazard. Do not allow any liquid to get inside charger.
CAUTION: Burn hazard. To reduce the risk of injury, charge only D
WALT rechargeable
E
batteries. Other types of batteries may burst causing personal injury and damage.
CAUTION: Under certain conditions, with the charger plugged in to the power supply, the
exposed charging contacts inside the charger can be shorted by foreign material. Foreign
materials of a conductive nature such as, but not limited to, steel wool, aluminum foil, or any
buildup of metallic particles should be kept away from charger cavities. Always unplug the charger
from the power supply when there is no battery pack in the cavity. Unplug charger before
attempting to clean.
• DO NOT attempt to charge the battery pack with any chargers other than the ones in
this manual. The charger and battery pack are specifically designed to work together.
• These chargers are not intended for any uses other than charging D
WALT
E
rechargeable batteries. Any other uses may result in risk of fire, electric shock or
electrocution.
• Do not expose charger to rain or snow.
• Pull by plug rather than cord when disconnecting charger. This will reduce risk of damage
to electric plug and cord.
• Make sure that cord is located so that it will not be stepped on, tripped over, or
otherwise subjected to damage or stress.
• Do not use an extension cord unless it is absolutely necessary. Use of improper extension
cord could result in risk of fire, electric shock, or electrocution.
• An extension cord must have adequate wire size (AWG or American Wire Gauge) for
safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that
is 16 gauge has more capacity than 18 gauge. When using more than one extension to make
up the total length, be sure each individual extension contains at least the minimum wire size.

• Do not place any object on top of charger or place the charger on a soft surface that
might block the ventilation slots and result in excessive internal heat. Place the charger
in a position away from any heat source. The charger is ventilated through slots in the top and
the bottom of the housing.
• Do not operate charger with damaged cord or plug — have them replaced immediately.
• Do not operate charger if it has received a sharp blow, been dropped, or otherwise
damaged in any way. Take it to an authorized service center.
• Do not disassemble charger; take it to an authorized service center when service or
repair is required. Incorrect reassembly may result in a risk of electric shock, electrocution or
fire.
• 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 2 chargers together.
• The charger is designed to operate on standard household electrical power (120 Volts).
Do not attempt to use it on any other voltage. This does not apply to the vehicular charger.
Using Automatic Tune-Up™ Mode
The Automatic Tune-Up™ Mode equalizes or balances the individual cells in the battery pack
allowing it to function at peak capacity. Battery packs should be tuned up weekly or after 10
charge/discharge cycles or whenever the pack no longer delivers the same amount of work. To
use the Automatic Tune-Up™, place the battery pack in the charger and leave it for at least 8
hours. The charger will cycle through the following modes.
1. The red light will blink continuously indicating that the 1-hour charge cycle has started.
2. When the 1-hour charge cycle is complete, the light will stay on continuously and will no longer
blink. This indicates that the pack is fully charged and can be used at this time.
3. Whenever the pack is left in the charger after the initial 1-hour charge, the charger will begin
the Automatic Tune-Up™ Mode. This mode continues up to 8 hours or until the individual cells
