GENERAL POWER TOOL SAFETY WARNINGS

WARNING: Read all safety warnings, instructions,
illustrations and specifications provided with this
power tool. Failure to follow all instructions listed below
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.
f ) If operating a power tool in a damp location is
unavoidable, use a residual current device (RCD)
protected supply. Use of an RCD 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 a 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 energising 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 and clothing away from
moving parts. Loose clothes, jewellery 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.
h ) Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause severe
injury within a fraction of a second.

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 remove the battery pack, if detachable, 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 and accessories. 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.
h ) Keep handles and grasping surfaces dry, clean and
free from oil and grease. Slippery handles and grasping
surfaces do not allow for safe handling and control of the
tool in unexpected situations.

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 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.
e ) Do not use a battery pack or tool that is damaged or
modified. Damaged or modified batteries may exhibit
unpredictable behaviour resulting in fire, explosion or risk
of injury.
f ) Do not expose a battery pack or tool to fire or
excessive temperature. Exposure to fire or temperature
above 130 °C may cause explosion.
g ) Follow all charging instructions and do not charge
the battery pack or tool outside the temperature
range specified in the instructions. Charging
improperly or at temperatures outside the specified range
may damage the battery and increase the risk of fire.

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.
b ) Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.

Additional Specific Safety Instructions for

Cut‑Off Machines

a ) The guard provided with the tool must be securely
attached to the power tool and positioned for
maximum safety, so the least amount of wheel is
exposed towards the operator. Position yourself
and bystanders away from the plane of the rotating
wheel. The guard helps to protect operator from broken
wheel fragments and accidental contact with wheel.
b ) Use only bonded reinforced wheels or diamond
blades for your power tool. Just because an accessory
can be attached to your power tool, it does not assure
safe operation.
c ) The rated speed of the accessory must be at least
equal to the maximum speed marked on the power
tool. Accessories running faster than their rated speed can
break and fly apart.
d ) Wheels must be used only for recommended
applications. For example: do not grind with the side
of cut‑off wheel. Abrasive cut‑off wheels are intended
for peripheral grinding, side forces applied to these wheels
may cause them to shatter.
e ) Always use undamaged wheel flanges that are of
correct diameter for your selected wheel. Proper
wheel flanges support the wheel thus reducing the
possibility of wheel breakage.
f ) Do not use worn down reinforced wheels from larger
power tools. Wheels intended for a larger power tool
are not suitable for the higher speed of a smaller tool and
may burst.
g ) The outside diameter and the thickness of your
accessory must be within the capacity rating of
your power tool. Incorrectly sized accessories cannot be
adequately guarded or controlled.
h ) The arbor size of wheels and flanges must properly
fit the spindle of the power tool. Wheels and flanges
with arbour holes that do not match the mounting
hardware of the power tool will run out of balance, vibrate
excessively and may cause loss of control.
i ) Do not use damaged wheels. Before each use,
inspect the wheels for chips and cracks. If power tool
or wheel is dropped, inspect for damage or install an
undamaged wheel. After inspecting and installing
the wheel, position yourself and bystanders away
from the plane of the rotating wheel and run the
power tool at maximum no load speed for one
minute. Damaged wheels will normally break apart
during this test time.
j ) Wear personal protective equipment. Depending
on application, use face shield, safety goggles or
safety glasses. As appropriate, wear dust mask,
hearing protectors, gloves and shop apron capable
of stopping small abrasive or workpiece fragments.
The eye protection must be capable of stopping
flying debris generated by various operations. The

dust mask or respirator must be capable of filtering
particles generated by your operation. Prolonged
exposure to high intensity noise may cause hearing loss.
k ) Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear
personal protective equipment. Fragments of
workpiece or of a broken wheel may fly away and cause
injury beyond immediate area of operation.
l ) Hold the power tool by insulated gripping surfaces
only, 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.
m ) Never lay the power tool down until the accessory
has come to a complete stop. The spinning wheel
may grab the surface and pull the power tool out of
your control.
n ) Do not run the power tool while carrying it at your
side. Accidental contact with the spinning accessory
could snag your clothing, pulling the accessory into
your body.
o ) Regularly clean the power tool’s air vents. The
motor’s fan will draw the dust inside the housing and
excessive accumulation of powdered metal may cause
electrical hazards.
p ) Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
q ) Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in
electrocution or shock

Kickback is a sudden reaction to a pinched or snagged rotating
wheel. Pinching or snagging causes rapid stalling of the rotating
wheel which in turn causes the uncontrolled power tool to be
forced in the direction opposite of the wheel’s rotation at the point
of the binding.
For example, if an abrasive wheel is snagged or pinched by the
workpiece, the edge of the wheel that is entering into the pinch
point can dig into the surface of the material causing the wheel
to climb out or kick out. The wheel may either jump toward or
away from the operator, depending on direction of the wheel’s
movement at the point of pinching. Abrasive wheels may also
break under these conditions.
Kickback is the result of power tool misuse and/or incorrect
operating procedures or conditions and can be avoided by taking
proper precautions as given below.

a ) Maintain a firm grip on the power tool and position
your body and arm to allow you to resist kickback
forces. Always use auxiliary handle, if provided,
for maximum control over kickback or torque
reaction during start‑up. The operator can control
torque reactions or kickback forces, if proper precautions
are taken.

b ) Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
c ) Do not position your body in line with the rotating
wheel. Kickback will propel the tool in direction opposite
to the wheel’s movement at the point of snagging.
d ) Use special care when working corners, sharp edges
etc. Avoid bouncing and snagging the accessory.
Corners, sharp edges or bouncing have a tendency to
snag the rotating accessory and cause loss of control
or kickback.
e ) Do not attach a saw chain, woodcarving blade,
segmented diamond wheel with a peripheral gap
greater than 10 mm or toothed saw blade. Such
blades create frequent kickback and loss of control.
f ) Do not “jam” the wheel or apply excessive pressure.
Do not attempt to make an excessive depth of
cut. Overstressing the wheel increases the loading and
susceptibility to twisting or binding of the wheel in the cut
and the possibility of kickback or wheel breakage.
g ) When wheel is binding or when interrupting a cut
for any reason, switch off the power tool and hold
the power tool motionless until the wheel comes to
a complete stop. Never attempt to remove the wheel
from the cut while the wheel is in motion otherwise
kickback may occur. Investigate and take corrective
action to eliminate the cause of wheel binding.
h ) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully re‑enter the cut. The wheel may bind, walk up
or kickback if the power tool is restarted in the workpiece.
i ) Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own
weight. Supports must be placed under the workpiece
near the line of cut and near the edge of the workpiece on
both sides of the wheel.
j ) Use extra caution when making a “pocket cut” into
existing walls or other blind areas. The protruding
wheel may cut gas or water pipes, electrical wiring or
objects that can cause kickback.

Additional Safety Information

Do not use the upper quarter of the wheel for cutting.
Serious injury may result due to kickback.
Use of accessories not specified in this manual is not
recommended and may be hazardous. Use of power
boosters that would cause the tool to be driven at speeds
greater than its rated speed constitutes misuse.
Do not use circular saw blades with this tool. Serious
injury may result.
Avoid bouncing the wheel or giving it rough treatment.
If this occurs, stop the tool and inspect the wheel for cracks
or flaws.
Direct sparks away from operator, bystanders or
flammable materials. Sparks may be produced while using
a sander or grinder. Sparks may cause burns or start fires.
Always use front handle. Tighten the handle securely.
The front handle should always be used to maintain control of
the tool at all times.
Never cut into area that may contain electrical wiring or
piping. Serious injury may result.
Clean out your tool often, especially after heavy use.
Dust and grit containing metal particles often accumulate on
interior surfaces and could create an electric shock hazard.
Do not operate this tool for long periods of time.
Vibration caused by tool action may be harmful to your
hands and arms. Use gloves to provide extra cushion and
limit exposure by taking frequent rest periods.
Dust, crystalline material, vapor and smoke may be
produced while working. Always wear a dust mask or
respiratory protection. Danger for health!

Residual Risks

In spite of the application of the relevant safety regulations
and the implementation of safety devices, certain residual risks
cannot be avoided. These are:

Impairment of hearing.
Risk of personal injury due to flying particles.
Risk of burns due to accessories becoming hot during operation.
Risk of personal injury due to prolonged use.
Health hazards caused by breathing dust developed when
working in concrete and/or masonry.

Charging a Battery

1. Plug the charger into an appropriate outlet before inserting
battery pack.
2. Insert the battery pack 24 into the charger, making sure the
battery pack is fully seated in the charger. The red (charging)
light will blink repeatedly, indicating that the charging
process has started.
3. The completion of charge will be indicated by the red
light remaining ON continuously. The battery pack is fully
charged and may be used at this time or left in the charger.
To remove the battery pack from the charger, push the
battery release button 16 on the battery pack.

NOTE: To ensure maximum performance and life of lithium‑ion
battery packs, charge the battery pack fully before first use.

Charger Operation
Refer to the indicators below for the charge status of the battery pack.

Charge Indicators

The red light will continue to blink, but a yellow indicator light
will be illuminated during this operation. Once the battery pack
has reached an appropriate temperature, the yellow light will
turn off and the charger will resume the charging procedure.
The compatible charger(s) will not charge a faulty battery pack.
The charger will indicate faulty battery by refusing to light.
NOTE: This could also mean a problem with a charger.
If the charger indicates a problem, take the charger and battery
pack to be tested at an authorised service centre.

Hot/Cold Pack Delay
When the charger detects a battery pack that is too hot or too
cold, it automatically starts a Hot/Cold Pack Delay, suspending
charging until the battery pack has reached an appropriate
temperature. The charger then automatically switches to the pack
charging mode. This feature ensures maximum battery pack life.
A cold battery pack will charge at a slower rate than 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.
The DCB118 charger is equipped with an internal fan designed to
cool the battery pack. The fan will turn on automatically when the
battery pack needs to be cooled. Never operate the charger if the
fan does not operate properly or if ventilation slots are blocked.
Do not permit foreign objects to enter the interior of the charger.

Electronic Protection System
XR Li‑Ion tools are designed with an Electronic Protection
System that will protect the battery pack against overloading,
overheating or deep discharge.
The tool will automatically turn off if the Electronic Protection
System engages. If this occurs, place the lithium‑ion battery
pack on the charger until it is fully charged.

Wall Mounting
These chargers are designed to be wall mountable or to sit
upright on a table or work surface. If wall mounting, locate the
charger within reach of an electrical outlet, and away from a
corner or other obstructions which may impede air flow. Use
the back of the charger as a template for the location of the
mounting screws on the wall. Mount the charger securely using
drywall screws (purchased separately) at least 25.4 mm long
with a screw head diameter of 7–9 mm, screwed into wood to
an optimal depth leaving approximately 5.5 mm of the screw
exposed. Align the slots on the back of the charger with the
exposed screws and fully engage them in the slots.

Charger Cleaning Instructions

WARNING: Shock hazard. Disconnect the charger
from the AC outlet before cleaning. Dirt and grease
may be removed from the exterior of the charger using a
cloth or soft non‑metallic brush. Do not use water or any
cleaning solutions. Never let any liquid get inside the tool;
never immerse any part of the tool into a liquid.

(ADR). Lithium‑ion cells and batteries have been tested to
section 38.3 of the UN Recommendations on the Transport of
Dangerous Goods Manual of Tests and Criteria.
In most instances, shipping a DeWALT battery pack will
be excepted from being classified as a fully regulated
Class 9 Hazardous Material. In general, only shipments containing
a lithium‑ion battery with an energy rating greater than 100 Watt
Hours (Wh) will require being shipped as fully regulated Class 9.
All lithium‑ion batteries have the Wh rating marked on the pack.
Furthermore, due to regulation complexities, DeWALT does
not recommend air shipping lithium‑ion battery packs alone
regardless of Wh rating. Shipments of tools with batteries (combo
kits) can be air shipped as excepted if the Wh rating of the battery
pack is no greater than 100 Wh.
Regardless of whether a shipment is considered excepted
or fully regulated, it is the shipper’s responsibility to consult
the latest regulations for packaging, labeling/marking and
documentation requirements.
The information provided in this section of the manual is
provided in good faith and believed to be accurate at the time
the document was created. However, no warranty, expressed or
implied, is given. It is the buyer’s responsibility to ensure that its
activities comply with the applicable regulations.
Transporting the FLEXVOLTTM Battery
The DeWALT FLEXVOLTTM battery has two modes: Use
and Transport.
Use Mode: When the FLEXVOLTTM battery stands alone or is in
a DeWALT 18V product, it will operate as an 18V battery. When
the FLEXVOLTTM battery is in a 54V or a 108V (two 54V batteries)
product, it will operate as a 54V battery.
Transport Mode: When the cap is attached to the FLEXVOLTTM
battery, the battery is in Transport mode. Keep the cap
for shipping.
When in Transport mode, strings
of cells are electrically
disconnected within the pack,
resulting in 3 batteries with a
lower Watt hour (Wh) rating as compared to 1 battery with a
higher Watt hour rating. This increased quantity of 3 batteries
with the lower Watt hour rating can exempt the pack from
certain shipping regulations that are imposed upon the higher
Watt hour batteries.
For example, the Transport
Wh rating might indicate
3 x 36 Wh, meaning

3 batteries of 36 Wh each. The Use Wh rating might indicate
108 Wh (1 battery implied).
Storage Recommendations
1. The best storage place is one that is cool and dry away from
direct sunlight and excessive heat or cold. For optimum
battery performance and life, store battery packs at room
temperature when not in use.
2. For long storage, it is recommended to store a fully charged
battery pack in a cool, dry place out of the charger for
optimal results.
NOTE: Battery packs should not be stored completely
depleted of charge. The battery pack will need to be recharged
before use.
