The vibration and/or noise emission level given in this information
sheet has been measured in accordance with a standardised test
given in EN62841 and may be used to compare one tool with
another. It may be used for a preliminary assessment ofexposure.
WARNING: The declared vibration and/or noise
emission
level represents the main applications of the tool. However,
if the tool is used for different applications, with different
accessories or is poorly maintained, the vibration and/or
noise emission may differ. This may significantly increase the
exposure level over the total workingperiod.
An estimation of the level of exposure to vibration and/or
noise should also take into account the times when the tool is
switched off or when it is running but not actually doing the
job. This may significantly reduce the exposure level over the
total workingperiod.
Identify additional safety measures to protect the operator
from the effects of vibration and/or noise such as: maintain
the tool and the accessories, keep the hands warm (relevant
for vibration), organisation of workpatterns.

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.
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.
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

ENGLISH
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.
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.
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.
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.

Refer to the indicators below for the charge status of the batterypack.
Charge Indicators
FCharging I
GFully Charged J
HHot/Cold Pack Delay* K
*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

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.
