General Safety Rules - For All Battery Operated Tools
_ WARNING! Read all instructions. Failure to follow all instructions listed below
may result in electric shock, fire and/or serious injury. The term "power tool" in all
of the warnings listed below refers to your mains-operated (corded) power tool or bat-
tery-operated (cordless) power tool
SAVE THESE INSTRUCTIONS
1) WORK AREA SAFETY
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
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
or fumes.
c) Keep children and bystanders away while operating a power tooL Distractions can
cause you to lose control
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 electric shock.
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 or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
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 electric shock. Replace or repair damaged cords.
Make sure your extension cord is in good condition. Use only 3-wire extension cords that
have 3-prong grounding-type plugs and 3-pole receptacles that accept the tool's plug.
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 electric shock. When using
an extension cord, be sure to use one heavy enough to carry the current your product will
draw. An undersized cord will cause a drop in line voltage resulting in loss of power and
overheating. The following table shows the correct size to use depending on cord length
and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage
number, the heavier the cord.

3) PERSONAL SAFETY
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 personal injury
b) Use safety equipment. Always wear eye protection. Safety equipment such as dust
mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate condi-
tions will reduce personal injuries.
c) Avoid accidental starting. Ensure the switch is in the off-position before plugging
in. Carrying power tools with your finger on the switch or plugging in power tools that have
the switch on invites accidents.
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 personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better
control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and
gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in
moving parts. Air vents often cover moving parts and should also be avoided.
g) ff devices are provided for the connection of dust extraction and collection facilities,
ensure these are connected and properly used. Use of these devices can reduce dust-
related hazards.
4) POWER TOOL USE AND CARE
a) Do not force the power tooL Use the correct power tool for your application. The cor-
rect power tool will do the job better and safer at the rate for which it was designed.
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 be repaired.
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 tool accidentally.
d) Store idle power tools out of the reach of children and do not allow persons unfa-
miliar with the power tool or these instructions to operate the power tool Power
tools are dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or binding of moving parts, breakage
of parts and any other condition that may affect the power tools operation, ff
damaged, have the power tool repaired before use. Many accidents are caused by
poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to control
g) Use the power tool, accessories and tool bits etc., in accordance with these
instructions and in the manner intended for the particular type of power tool, 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.
5) BATTERY TOOL USE AND CARE
a) Ensure the switch is in the off position before inserting battery pack. Inserting the
battery pack into power tools that have the switch on invites accidents.
b) 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.
c) Use power tools only with specifically designated battery packs. Use of any other
battery packs may create a risk of injury and fire.
d) 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 bums or a fire.
e) 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.
6) SERVICE
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 is maintained.
Specific Safety Rules for Hammerdrills
• Hold tool by insulated gripping surfaces when performing an operation where the tool
may contact hidden wiring or its own cord. Contact with a "live" wire will also make
exposed metal parts of the tool "live" and shock the operator.
• Wear ear protectors with impact drills. Exposure to noise can cause hearing loss.
• Use auxiliary handles supplied with the tooL Loss of control can cause personal injury.
• 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 loss of
control
• Wear ear protectors when hammering for extended periods of time. Prolonged expo-
sure to high intensity noise can cause hearing loss. Temporary hearing loss or serious ear
drum damage may result from high sound levels generated by hammerdrilling.
• Wear safety goggles or other eye protection. Hammering and drilling operations cause
chips to fly. Flying particles can cause permanent eye damage.
• Always use the side handle supplied with the tool Keep a firm grip on the tool at all times.
Do not attempt to operate this tool without holding it with both hands.
• Hammer bits and tools get hot during operation. Wear gloves when touching them.
J& 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 $12.6 ($3. 19) hearing protection,
• NIOSH/OSHA respiratory protection.
J& 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.
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 disburse 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.

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.
_ WARNING: Shock hazard. Do not allow any liquid to get inside charger.
_,CAUTION: Bum hazard. To reduce the risk of injury, charge only DEWALT 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
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 DEWALT recharge-
able 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 other-
wise 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 charg-
er 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 mount charger on wall or permanently affix charger to any surface. The
charger is intended to use on a flat, stable surface (i.e., table top, bench top).
• Do not operate charger with damaged cord or plug -- have them replaced immediately.
• Do not operate charger ff 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.
