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 acci-
dents.
• 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. Distrac-
tions 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 suit-
able 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 medica-
tion. 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.
• Avoid accidental starting. Be sure switch is in the locked or off position before insert-
ing 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 bal-
ance 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 pre-
ventative safety measures reduce the risk of starting the tool accidentally.
• Store idle tools out of reach of children and other untrained persons. Tools are dan-
gerous 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 con-
nection 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 tools 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 mainte-
nance 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.
• When working on a ladder or on scaffolding be sure to lay the tool down on its side
when not in use. Some tools with large battery packs will stand upright but may be easily
knocked over.
• The label on your tool may include the following symbols.
V....................volts

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.
Important Safety Instructions for Battery Packs
The battery pack is not fully charged out of the carton! First read the safety instruc-
tions below. Then follow charging notes and procedures.
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 temper-
ature conditions. This does not indicate a failure. However, if the outer seal is broken and this
leakage gets on your skin:
a. Wash quickly with soap and water.
b. Neutralize with a mild acid such as lemon juice or vinegar.
c. If 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 potassi-
um hydroxide.)
• Do not carry extra battery packs in aprons, pockets, or tool boxes along with other metal objects.
Battery pack could be short circuited causing damage to the battery pack and possibly causing
severe burns or fire.
• Charge the battery packs only in D WALT chargers.
E
• NOTE: The batteries in your battery pack are the nickel–cadmium type. Cadmium is considered
to be a toxic material by the Environmental Protection Agency. Before disposing of damaged or
worn out Nickel–Cadmium battery packs, check with your state Environmental Protection Agency
to find out about special restrictions on the disposal of these battery packs or return them to a
D WALT certified service center for recycling.
E
• DO NOT store or use the tool and battery pack in locations where the temperature may reach or
exceed 105°F (such as outside sheds or metal buildings in summer).
DANGER: Never attempt to open the battery pack for any reason. If battery pack case is
cracked or damaged, do not insert into charger. Danger of electric shock or electrocution.
Damaged battery packs should be returned to service center for recycling.

The RBRC™ Seal
The RBRC™ (Rechargeable Battery Recycling Corporation) Seal on the nickel-
cadmium battery (or battery pack) indicates that the costs to recycle the battery
(or battery pack) at the end of its useful life have already been paid by D
In some areas, it is illegal to place spent nickel-cadmium batteries in the trash or
municipal solid waste stream and the RBRC program provides an environmen-
tally conscious alternative.
RBRC in cooperation with D WALT and other battery users, has established programs in the
E
United States to facilitate the collection of spent nickel-cadmium batteries. Help protect our
environment and conserve natural resources by returning the spent nickel-cadmium battery to
an authorized D WALT service center or to your local retailer for recycling. You may also con-
E
tact your local recycling center for information on where to drop off the spent battery.
