General Power Tool Safety Warnings
WARNING! 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.
English
1
f) If operating a power tool 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
of moving 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.
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, 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) Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one type of
English
2
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 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 burns 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 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.
Additional Safety Rules for Grease Guns
• Parts of the tool or the hose assembly can break or rupture
due to high pressure. Risk of serious injury may occur.
Before using, always inspect the tool and hose assembly for
damage or wear. Never use if any part of the tool is damaged or
worn.
• Use only DeWALT-approved flexible hoses. Hold the hose only
by the flexible hose safety spring guard to avoid personal serious
injury.
• If the hose kinks or is damaged, a rupture may occur which
could cause serious injury. Replace the hose at the first sign of
wear, kink or damage.
• Only use the grease recommended in this manual. Refer to
the Technical Information chart under Using the Grease Gun.
• To reduce the risk of serious personal injury, do not use
the grease gun around or on moving parts, mechanisms or
running equipment.
• Air vents often cover moving parts and should be avoided.
Loose clothes, jewelry or long hair can be caught in moving parts.
WARNING: Risk of injection or severe injury. Rupture of
components can inject grease into skin or eyes, causing
serious injury or infection. Do not treat as a simple cut. Seek
immediate medical attention.
WARNING: Output can be at high pressure. Do not direct
discharge at yourself or others.
WARNING: The grease gun may generate high pressure—up
to 10,000 psi (690 bar). Always wear gloves during operation.
Keep hands clear of the exposed rubber portion of the hose.
WARNING: Risk of fire. Grease may be flammable. Do not
expose to fire or high temperatures. Read and follow all warnings and
instructions from the lubricant manufacturer.
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,
English
3
• 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.
WARNING: Always wear proper personal hearing protection
that conforms to ANSI S12.6 (S3.19) during use. Under some
conditions and duration of use, noise from this product may
contribute to hearing loss.

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-Ion)
• 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.

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.
WARNING: Shock hazard. Do not allow any liquid to get inside the
charger. Electric shock may result.
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.

trouble indication as the original, have the charger and the battery
pack tested at an authorized service center.
HOT/COLD DELAY
DCB101, DCB102, DCB103
These chargers have a hot/cold delay feature. When the charger
detects a battery that is too hot or too cold, it automatically starts
a delay, suspending charging. The red light flashes long, then short
while in the hot/cold delay mode.
Once the battery has reached an optimum temperature, the charger
will automatically resume the charging procedure. This feature
ensures maximum battery life.
DCB107, DCB112, DCB113, DCB115
These chargers have a hot/cold delay feature. When the charger
detects a battery that is too hot or too cold, it automatically starts a
delay, suspending charging. The red light will continue to blink, but a
yellow indicator light will be illuminated during this suspension.
Once the battery has reached an optimum temperature, the yellow
light will turn off and the charger will automatically resume the
charging procedure. This feature ensures maximum battery life.
LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the charge
indicator showing Pack Charged.
WEAK BATTERY PACKS: Weak batteries will continue to function
but should not be expected to perform as much work.
FAULTY BATTERY PACKS
DCB101, DCB102, DCB103

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 +104°F (+40°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;
b. Check to see if receptacle is connected to a light switch which
turns power off when you turn out the lights;
c. Move the charger and battery pack to a location where the
surrounding air temperature is approximately 65 °F – 75 °F
(18° – 24°C);
d. If charging problems persist, take the tool, battery pack and
charger to your local service center.
5. The battery pack should be recharged when it fails to produce
sufficient power on jobs which were easily done previously. DO
NOT CONTINUE to use under these conditions. Follow the
charging procedure. You may also charge a partially used pack
whenever you desire with no adverse effect on the battery pack.
6. 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 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.
7. Do not freeze or immerse the charger in water or any other liquid.
WARNING: Shock hazard. Don’t allow any liquid to get inside the
charger. Electric shock may result.
WARNING: Burn hazard. Do not submerge the battery pack in
any liquid or allow any liquid to enter the battery pack. Never attempt
to open the battery pack for any reason. If the plastic housing of the
battery pack breaks or cracks, return to a service center for recycling.

FILLER PUMP FILLING FROM A BULK CONTAINER
(FIG. 5, 6, 9)
This tool comes with a 1/8" NPT fill port
FIG. 9
(Z, Fig. 5) for attaching a low pressure fill
coupler onto the unit.
WARNING: Never thread a highpressure coupler onto the grease
gun’s 1/8" NPT fill port. Serious injury
may occur due to excessive pressure.
Use low-pressure couplers only.
CAUTION: The fill pump loader must
connect correctly with the grease gun’s
1/8" NPT port. The filler pump may
not operate if the components are not
compatible.
Installing the low pressure coupler
(not supplied with the tool)
1. Thread the grease tube assembly (N)
back into the grease gun and screw it
in securely.
2. Pull the grease tube handle (L) out
as far as it will go, then secure the
grease tube rod (M) into the retaining
slot (O) by moving the rod to the side.
Ensure the rod is placed securely in
the slot to prevent it from disengaging.
3. Remove the 1/8" NPT fill port plug
(AA) from the fill port.
4. Thread the appropriate low pressure
coupler onto the 1/8" NPT fill port (Z).
English

5. Release the grease tube rod (M) from the retaining slot (O) and
slowly press it back into the tube.
6. Use the purge valve (X) to bleed off any air that may be trapped
in the cartridge. Refer to Purging Air Pockets.
FILLING THE TOOL FROM THE LOW PRESSURE FILLER
PUMP (FIG. 2, 5, CON9)
1. Pull back on the grease tube handle slowly and rotate the rod until
it is secure in place.
NOTE: Do not lock the rod into the retaining slot (O).
2. Connect the low pressure fitting on the grease gun to the
appropriate low pressure fitting on the filler pump. These fittings
DO NOT lock together. This prevents the grease gun cartridge
from being over filled.
3. Fill until the rod is pushed out of the grease tube approximately
8" (20cm). Do not overfill. If the rod fails to move during the filling
process, stop. This indicates that the rod is not connected to the
plunger and step one must be repeated before proceeding.
4. Rotate rod to release and carefully push rod back into the grease
tube.
5. Use the purge valve (X) to bleed off any air that may be trapped
in the cartridge. Refer to Purging Air Pockets.
Purging Air Pockets (Fig. 2, 5)
IMPORTANT: Air pockets in the grease can cause the grease gun to
lose prime. Eliminate air pockets after each refill or if the grease gun
fails to pump grease:
1. Unscrew the purge valve (X) without removing it, until all air has
escaped.
2. Tighten the purge valve (X).
3. Uncap the flexible hose (G) then depress the variable speed
trigger switch (A) for 10–20 seconds.
4. If grease fails to flow through the hose, repeat from step 1.
NOTE: This tool has been tested at the factory, which may result in
a small amount of grease left in the grease tube and hose assembly.
It is recommended to purge the tool with the brand of grease to be
used before first use.

the fuel gauge button (FF). A combination
of the three green LED lights will illuminate
designating the level of charge left. When
the level of charge in the battery is below
the usable limit, the fuel gauge will not
illuminate and the battery will need to be
recharged.
NOTE: The fuel gauge is only an indication
of the charge left on the battery pack. It
does not indicate tool functionality and is subject to variation based
on product components, temperature and end-user application.

Using the Grease Gun (Fig. 2)
WARNING: To reduce the risk of serious personal injury,
always maintain a grip on the handle (C) when operating the
grease gun or positioning the hose onto fittings.
To operate the grease gun, hold the grease gun by the handle (C), or
place it on a stable surface upright on its rubber feet (R) maintaining
a grip on the handle. Holding the hose by the flexible hose safety
spring guard (H), connect the flexible hose grease coupler (I) or
other appropriate grease coupler, onto the grease fitting to be filled.
Carefully depress the variable speed trigger switch to begin the filling
process. Once the correct amount of grease has been dispensed,
release the trigger and remove the coupler from the grease fitting. If
the coupler does not release, there may still be residual pressure in
the line. Moving the coupler from side to side can relieve the residual
pressure so it can be removed from the coupling. If the coupler leaks
excessively or does not hold on to the grease fitting, it should be
replaced.
