General Power Tool Safety Warnings

_ ARNING! Read all safety warnings and all instructions.

Failure to follow the warnings and instructions may result in

electric shock, fire and/or serious injury,

SAVE ALL WARNINGS AND INSTRUCTIONS

FOR FUTURE REFERENCE

The term "power tool" in the warnings refers to your mains-operated
(corded) power tool or battery-operated (cordless) power tool

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.

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.

If operating a powertool in a damp location is unavoidable,
use a ground fault circuit interrupter (GFCI) protected

supply. Use of a GFCI reduces the risk of electric shock.

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 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 personal injuries.

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 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 jewelry.

Keep your hair, clothing and gloves away from moving

parts. Loose clothes, jewelry or long hair can be caught in

moving parts.

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-related hazards.

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 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 unfamiliar 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

ofmoving 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 power tools.
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, 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) BATFERY 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

battery pack.

b) Use power tools only with specifically designated battery

packs. Use of any other battery packs may create a risk of

injury and fire.

c)When battery pack is not in use, keep H 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.

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 or bums.

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.

Additional Specific Safety Rules for

Reciprocating Saws

• Hold power tool by insulated gripping surfaces, when
performing an operation where the cutting accessory may

contact hidden wiring. Cutting accessory contacting a "live"
wire may make exposed metal parts of the power tool "live" and

could give the operator an electric shock.

• Use clamps or another practical way to secure and support

the workpiece to a stable platform. Holding the work by hand
or against your body leaves H unstable and may lead to loss
of control.

• Hold saw firmly with both hands for all cutting operations.

During cutting operations, the blade may suddenly bind in the work
and may cause the saw to kickback towards the operator.

• Keep hands away from moving parts. Never place your hands

near the cutting area.

• Use extra caution when cutting overhead and pay particular

attention to overhead wires which may be hidden from view.

Anticipate the path of falling branches and debris ahead of time.

• Do not operate this tool for long periods of time. Vibration
caused by the operating action of this tool may cause permanent

injury to fingers, hands, and arms. Use gloves to provide extra
cushion, take frequent rest periods, and limit daily time of use.

_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/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.

Alwaysuse NIOSH/OSHAapprovedrespiratoryprotection

appropriateforthedustexposure. Direct particles away from face

and body.

_WARNING: Always wear proper personal hearing protection
that conforms to ANSI $12.6 ($3.19) during use. Under some

conditions and duration of use, noise from this product may
contribute to hearing loss.

_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.

trigger switch locked on. Never tape the trigger switch in the

ON position.

i_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,beendropped,runoverordamagedinanyway(e.g.,pierced
withanail,hitwithahammer,steppedon).Damagedbatterypacks

shouldbereturnedtotheservicecenterfor recycling.

A 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 (e.g., packed in suitcases and carry-on

luggage) 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.

SPECIFIC SAFETY INSTRUCTIONS FOR LITHIUM ION (Li-lon)

• 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.

A WARNING: Bum hazard. Battery liquid may be flammable if
exposed to spark or flame.

The RBRC TM Seal

The RBRCTM (Rechargeable Battery Recycling Corporation) Seal on the
nickel cadmium, nickel metal hydride or lithium ion

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 DEWALT. In
some areas, it is illegal to place spent nickel cadmium,

nickel metal hydride or lithium ion batteries in the trash
or municipal solid waste stream and the RBRC program provides an

environmentally conscious alternative.
RBRCTM, in cooperation with DEWALT and other battery users, has

established programs in the United States and Canada to facilitate
the collection of spent nickel cadmium, nickel metal hydride or lithium

ion batteries. Help protect our environment and conserve natural
resources by returning the spent nickel cadmium, nickel metal hydride

or lithium ion batteries to an authorized DEWALT service center 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.

Important Safety Instructions for All
Battery Chargers

SAVE THESE INSTRUCTIONS: This manual contains important

safety and operating instructions for battery chargers.

• Before using the charger, read all instructions and cautionary
markings on the charger, battery pack and product using the
battery pack.

A WARNING: Shock hazard. Do not allow any liquid to get inside the
charger. Electric shock may result.
i_,CAUTION: Burn hazard. To reduce the risk of injury, charge only
DEWALT rechargeable battery packs. Other types of batteries may
overheat and burst resulting in personal injury and property damage.

NOTICE: Under certain conditions, with the charger plugged into the

power supply, the charger can be shorted by foreign material Foreign

materials of a conductive nature, such as, but not limited to, grinding
dust, metal chips, steel wool, aluminum foil or any buildup of metallic

particles should be kept away from the charger cavities. Always unplug

the charger from the power supply when there is no battery pack in the
cavity, Unplug the 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 rechargeable batteries. Any other uses may

result in risk of fire, electric shock or electrocution.

• Do not expose the charger to rain or snow.

• Pull by the plug rather than the cord when disconnecting
the charger. This will reduce the risk of damage to the electric plug

and cord.

• Make sure that the 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.

• When operating a charger outdoors, always provide a dry

location and use an extension cord suitable for outdoor use.

Use of a cord suitable for outdoor use reduces the risk of electric

shock.

• 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. An undersized cord
will cause a drop in line voltage resulting in loss of power and
overheating. When using more than one extension to make up the

total length, be sure each individual extension contains at least the
minimum wire size. The following table shows the correct size to

use depending on cord length and nameplate ampere rating. If in
doubt, use the next heavier gauge. The lower the gauge number,

the heavier the cord.

Charge Indicators

This charger is designed to detect certain problems that can arise.

Problems are indicated by the red light flashing at a fast rate. If this
occurs, re-insert the battery pack into the charger. If the problem

persists, try a different battery pack to determine if the charger is
working properly. If the new pack charges correctly, then the original

pack is defective and should be returned to a service center or other
collection site for recycling. If the new battery pack elicits the same

trouble indication as the original, have the charger and the battery pack
tested at an authorized service center.

HOT/COLD DELAY
DCB101

This charger has a hot/cold delay feature: when the charger detects a
battery that is hot, it automatically starts a delay, suspending charging
until the battery has cooled. After the battery has cooled, the charger

automatically switches to the pack charging mode. This feature
ensures maximum battery life. The red light flashes long, then short

while in the hot/cold delay mode.

DCB107, DCB112

The DCB107 and DCB112 chargers have a hot/cold delay feature.
When the charger detects a battery that is hot, it automatically delays

charging until the battery has cooled. When the charger detects a
battery that is cold, it automatically delays charging until the battery
has warmed.

The red light will continue to blink, but a yellow indicator light will
be illuminated during this operation. Once the battery has cooled,

the yellow light will turn off and the charger will resume the charging
procedure.

LEAVING THE BATTERY PACK IN THE CHARGER

The charger and battery pack can be left connected with the charge
indicator showing Pack Charged.

WEAK BA'R'ERY PACKS: Weak batteries will continue to function
but should not be expected to perform as much work.

FAULTY BATTERY PACKS: This charger will not charge a faulty
battery pack. The charger will indicate faulty battery pack by refusing

to light or by displaying problem pack or charger.

NOTE: This could also mean a problem with a charger.
PROBLEM POWER LINE (DCB101)

Some chargers have a problem powerline indicator. When the charger
is used with some portable power sources such as generators or

sources that convert DC to AC, the charger may temporarily suspend
operation, flashing the red light with two fast blinks followed by a pause.

This indicates the power source is out of limits.

Wall Mounting

DCB107, DCB112

These chargers are designed to be wall mountable or to sit upright on
a table or work surface.

Ifwall mounting, locate the charger within reach of an electrical outlet.
Mount the charger securely using drywall screws at least 1"(25.4 mm)

long, screwed into wood to an optimal depth leaving approximately
7/32" (5.5 mm) of the screw exposed.

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 in an air
temperature below +40 °F (+4.5 °C), or above +105 °F (+40.5 °C).

This is important and will prevent serious damage to the battery
pack.

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 uninsulated trailer.

3. A cold battery pack will charge at about half the rate of 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 pack warms.

4. If the battery pack does not charge properly:
a. Check operation of receptacle by plugging in a lamp or other

appliance;

blade in the horizontal orientation allows cutting close to floors, walls

or ceilings where limited clearance is available. Ensure that the shoe is
pressed against the framing to avoid kickback.

FIG.8

Adjustable Shoe (DCS380 only) (Fig. 2, 9)

_,CAUTION: Cut hazard. To prevent loss of control, never use tool
without shoe.

Your DCS380 comes with an adjustable
shoe. The shoe will adjust to limit the

depth of cut. Hold the saw with the
underside facing up. Push the button on
the hand grip and slide the shoe out to

one of the three settings and release the
button.

The DCS381 comes with a fixed shoe that
is not adjustable.

Cutting (Fig. 10-13)

J_WARNING: Always use eye protection. All users and bystanders
must wear eye protection that conforms to ANSI Z87.1.

12

_WARNING: Exercise extra caution when cutting towards operator.

Always hold saw firmly with both hands while cutting.

Before cutting any type of material, be sure it is firmly anchored or
clamped to prevent slipping. Place blade lightly against work to be

cut, switch on saw motor and allow it to obtain maximum speed
before applying pressure. Whenever possible, the saw shoe must be

held firmly against the material being cut (Fig. 10). This will prevent the
saw from jumping or vibrating and minimize blade breakage. Any cuts

which put pressure on the blade such as angle or scroll cuts increase
potential for vibration, kickback, and blade breakage.

FIG. 10,

J_,WARNING: Use extra caution when cutting overhead and pay

particular attention to overhead wires which may be hidden from

view. Anticipate the path of falling branches and debris ahead of time.
AWARNING: Inspect work site for hidden gas pipes, water pipes,
or electrical wires before making blind or plunge cuts. Failure to do
so may result in explosion, property damage, electric shock, and/or

serious personal injury.

FLUSH-TO CU'R'ING (FIG. 11)

The compact design of the saw motor housing and spindle housing
permits extremely close cutting to floors, corners and other difficult
areas.

POCKET/PLUNGE cU'rFING - WOOD ONLY (FIG. 12)

The initial step in pocket cutting is to measure the surface area to be
cut and mark clearly with a pencil, chalk or scriber. Use the appropriate

blade for the application. The blade should be longer than 3-1/2"
(89 mm) and should extend past the shoe and the thickness of the
workpiece during the cut. Insert blade in blade clamp.
Next, tip the saw backward until the back edge of the shoe is resting
on the work surface and the blade clears the work surface (position 1,

Fig. 12). Now switch motor on, and allow saw to come up to speed.
Grip saw firmly with both hands and begin a slow, deliberate upward
swing with the handle of the saw, keeping the bottom of the shoe

firmly in contact with the workpiece (position 2, Fig. 12). Blade will
begin to feed into material. Always be sure blade iscompletely through

material before continuing with pocket cut.

13

NOTE: In areas where blade visibility is limited, use the edge of the
saw shoe as a guide. Lines for any given cut should be extended
beyond edge of cut to be made.

METAL CUTTING (FIG. 13}

Your saw has different FIG.13
metal cutting capacities

depending upon type of
blade used and the metal

to be cut. Use a finer
blade for ferrous metals

and a coarse blade for
non-ferrous materials. In

thin gauge sheet metals it
is best to clamp wood to
both sides of sheet. This
will insure a clean cut

without excess vibration
or tearing of metal. Always

remember not to force
cutting blade as this reduces blade life and causes costly blade

breakage.
NOTE: It is generally recommended that when cutting metals you

should spread a thin film of oil or other lubricant along the line ahead
of the saw cut for easier operation and longer blade life.
