The vibration and/or noise emission level given in this
information sheet has been measured in accordance with
a standardised test given in EN60745 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 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.

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.
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,

k ) Cut wood only. Do not use chain saw for purposes
not intended. For example: do not use chain saw for
cutting metal, plastic, masonry or non‑wood building
materials. Use of the chain saw for operations different
than intended could result in a hazardous situation.
l ) Do not attempt to fell a tree until you have an
understanding of the risks and how to avoid them.
Serious injury could occur to the operator or bystanders
while felling a tree.
m ) Do not attempt to fell a tree until you have an
understanding of the risks and how to avoid them.
Serious injury could occur to the operator or bystanders
while felling a tree.
Causes and operator prevention of kickback:
Kickback may occur when the nose or tip of the guide bar
touches an object, or when the wood closes in and pinches the
saw chain in the cut.
Tip contact in some cases may cause a sudden reverse reaction,
kicking the guide bar up and back towards the operator.
Pinching the saw chain along the top of the guide bar may push
the guide bar rapidly back towards the operator.
Either of these reactions may cause you to lose control of the saw
which could result in serious personal injury. Do not rely exclusively
upon the safety devices built into your saw. As a chain saw user,
you should take several steps to keep your cutting jobs free from
accident or injury.
Kickback is the result of chain saw misuse and/or incorrect
operating procedures or conditions and can be avoided by taking
proper precautions as given below:
a ) Maintain a firm grip, with thumbs and fingers
encircling the chain saw handles, with both hands
on the saw and position your body and arm to allow
you to resist kickback forces. Kickback forces can be
controlled by the operator, if proper precautions are
taken. Do not let go of the chain saw.
b ) Do not overreach and do not cut above shoulder height.
This helps prevent unintended tip contact and enables better
control of the chain saw in unexpected situations.
c ) Only use replacement guide bars and saw chains
specified by the manufacturer. Incorrect replacement
guide bars and saw chains may cause chain breakage
and/or kickback.
d ) Follow the manufacturer’s sharpening and
maintenance instructions for the saw chain. Decreasing
the depth gauge height can lead to increased kickback.
The Following Precautions Should Be
Followed to Minimize Kickback:
1 . Grip saw firmly. Hold the chain saw firmly with both
hands when the motor is running. Use a firm grip with
thumbs and fingers encircling the chain saw handles.
Chain saw will pull forward when cutting on the bottom edge
of the bar, and push backward when cutting along the top
edge of thebar.
General Chain Saw Safety Warnings
a ) Keep all parts of the body away from the saw chain
when the chain saw is operating. Before you start
the chain saw, make sure the saw chain is not
contacting anything. A moment of inattention while
operating chain saws may cause entanglement of your
clothing or body with the saw chain.
b ) Always hold the chain saw with your right hand
on the rear handle and your left hand on the front
handle. Holding the chain saw with a reversed hand
configuration increases the risk of personal injury and
should never be done.
c ) Hold the chain saw by insulated gripping surfaces
only, because the saw chain may contact hidden
wiring or its own cord. Saw chains contacting a "live"
wire may make exposed metal parts of the chain saw "live"
and could give the operator an electric shock.
d ) d) Wear eye protection. Further protective
equipment for hearing, head, hands, legs and feet
is recommended. Adequate protective equipment will
reduce personal injury from flying debris or accidental
contact with the saw chain.
e ) Do not operate a chain saw in a tree, on a ladder,
from a rooftop, or any unstable support. Operation of
a chain saw in this manner could result in serious personal
injury.
f ) Always keep proper footing and operate the chain
saw only when standing on fixed, secure and level
surface. Slippery or unstable surfaces may cause a loss of
balance or control of the chain saw.
g ) When cutting a limb that is under tension, be alert
for spring back. When the tension in the wood fibres is
released, the spring loaded limb may strike the operator
and/or throw the chain saw out of control.
h ) Use extreme caution when cutting brush and
saplings. The slender material may catch the saw chain
and be whipped toward you or pull you off balance.
i ) Carry the chain saw by the front handle with the
chain saw switched off and away from your body.
When transporting or storing the chain saw, always
fit the guide bar cover. Proper handling of the chain
saw will reduce the likelihood of accidental contact with
the moving saw chain.
j ) Follow instructions for lubricating, chain tensioning
and changing the bar and chain. Improperly tensioned
or lubricated chain may either break or increase the
chance for kickback.
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.

• Scabbard/Guide Bar Cover ‑ Enclosure fitted over guide bar
to help prevent tooth contact when saw is not inuse.
• Kickback ‑ The backward or upward motion, or both of the
guide bar occurring when the saw chain near the nose of the
top area of the guide bar contacts any object such as a log or
branch, or when the wood closes in and pinches the saw chain
in thecut.
• Kickback, Pinch ‑ The rapid pushback of the saw which can
occur when the wood closes in and pinches the moving saw
chain in the cut along the top of the guidebar.
• Kickback, Rotational ‑ The rapid upward and backward
motion of the saw which can occur when the moving saw
chain near the upper portion of the tip of the guide bar
contacts an object, such as a log orbranch.
• Limbing ‑ Removing the branches from a fallentree.
Contact with a “live” wire will make exposed metal parts of the
tool “live” and shock theoperator.
• Do not attempt operations beyond your capacity or
experience. Read thoroughly and understand completely all
instructions in thismanual.
• Before you start chain saw, make sure saw chain is not
contacting anyobject.
• Do not operate a chain saw with one hand! Serious injury
to the operator, helpers, or bystanders may result from one
handed operation. A chain saw is intended for two‑handed
useonly.
• Keep the handles dry, clean, and free of oil orgrease.
• Do not allow dirt, debris, or sawdust to build up on the motor
or outside airvents.
• Stop the chain saw before setting itdown.
• Do not cut vines and/or small underbrush.
• Use extreme caution when cutting small size brush and
saplings because slender material may catch the saw chain
and be whipped toward you or pull you offbalance.
2 . Do not overreach.
3 . Keep proper footing and balance at alltimes.
4 . Don’t let the nose of the guide bar contact a log, branch,
ground or otherobstruction.
5 . Don’t cut above shoulderheight.
6 . Use devices such as low kickback chain and reduced
kickback guide bars that reduce the risks associated
withkickback.
7 . Only use replacement bars and chains specified by the
manufacturer or theequivalent.
8 . Never let the moving chain contact any object at the tip

9 . Keep the working area free from obstructions such
as other trees, branches, rocks, fences, stumps, etc.
Eliminate or avoid any obstruction that your saw chain could
hit while you are cutting through a particular log orbranch.
10 . Keep your saw chain sharp and properly tensioned. A
loose or dull chain can increase the chance of kickback.
Check tension at regular intervals with the motor stopped and
tool unplugged, never with the motorrunning.
11 . Begin and continue cutting only with the chain moving
at full speed. If the chain is moving at a slower speed, there is
a greater chance for kickback tooccur.
12 . Cut one log at atime.
13 . Use extreme caution when re‑entering a previous cut.
Engage bucking spikes into wood and allow chain to reach full
speed before proceeding withcut.
14 . Do not attempt plunge cuts or borecuts.
15 . Watch for shifting logs or other forces that could close a
cut and pinch or fall intochain.
Kickback Safety Features
WARNING: The following features are included on your
saw to help reduce the hazard of kickback; however such
features will not totally eliminate this dangerous reaction.
As a chain saw user do not rely only on safety devices.
You must follow all safety precautions, instructions, and
maintenance in this manual to help avoid kickback and
other forces which can result in seriousinjury.
• Reduced‑Kickback Guide Bar, designed with a small radius
tip which reduces the size of the kickback danger zone on
bar tip. A reduced ‑ kickback guide bar is one which has
been demonstrated to significantly reduce the number and
seriousness of kickbacks when tested in accordance with
safety requirements for electric chainsaws.
• Low‑Kickback Chain, designed with a contoured depth gauge
and guard link which deflect kickback force and allow wood to
gradually ride into the cutter. A low‑kickback chain is a chain
which has met kickback performance requirements of ANSI
B175.1–2012.
• Do not operate chain saw while in a tree, on a ladder, on a
scaffold, or from any unstablesurface.
• Hold tool by insulated gripping surfaces when performing an
operation where the cutting tool may contact hidden wiring.

Charge Indicators
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
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.
• Make sure that 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.
• 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 charger 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 operate charger with damaged cord or plug—
have them replacedimmediately.
• Do not operate charger if it has received a sharp blow,
been dropped, or otherwise damaged in any way. Take it
to an authorised servicecentre.
• Do not disassemble charger; take it to an authorised service
centre when service or repair is required. Incorrect reassembly
may result in a risk of electric shock, electrocution orfire.
• In case of damaged power supply cord, the supply cord must
be replaced immediately by the manufacturer, its service agent
or similar qualified person to prevent anyhazard.
• 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 two chargerstogether.
• The charger is designed to operate on standard
230V household electrical power. Do not attempt to
use it on any other voltage. This does not apply to the
vehicularcharger.

NOTE: Use a high quality bar and chain oil for proper saw chain
and bar lubrication. As a temporary substitute, a non-detergent
SAE30 weight motor oil can be used. The use of a vegetable
based bar and chain oil is recommended when pruning trees.
Mineral oil is not recommended because it may harm trees.
Never use waste oil or very thick oil. These may damage
yourchainsaw.
Filling the Oil Reservoir
1. Unscrew counterclockwise and then remove the oil cap10.
Fill the reservoir with the recommended bar and chain
oil until the oil level has reached the top of the oil level
indicator9.
2. Refit the oil cap and tightenclockwise.
3. Periodically switch the chainsaw off and check the oil
level indicator to ensure the bar and chain are being
properlyoiled.

use wedges to open the cut and drop the tree along the
desired line of fall. When the tree begins to fall remove the
chainsaw from the cut, stop the motor, put the chainsaw
down, then use the retreat path planned. Be alert for
overhead limbs falling and watch yourfooting.

Limbing
Removing the branches from a fallen tree. When limbing, leave
larger lower limbs to support the log off the ground. Remove
the small limbs in one cut. Branches under tension should
be cut from the bottom of the branch towards the top to
avoid binding the chainsaw as shown below. Trim limbs from
opposite side keeping tree stem between you and saw. Never
make cuts with saw between your legs or straddle the limb to
becut.

WARNING: Recommend that first time users should
practice cutting on a sawhorse.
Cutting a felled tree or log into lengths. How you should
cut depends on how the log is supported. Use a saw horse
wheneverpossible as shownbelow.
1. Always start a cut with the saw chain running at fullspeed.
Common Cutting Techniques
Felling
The process of cutting down a tree. Do not fell trees in high
windconditions.
WARNING: Felling can result in injury. It should only be
performed by a trainedperson.
• A retreat path should be planned and cleared as necessary
before cuts are started. The retreat path should extend back
and diagonally to the rear of the expected line of fall as
shownbelow.

RETREAT
• Before felling is started, consider the natural lean of the
tree, the location of larger branches and the wind direction
to judge which way the tree will fall. Have wedges (wood,
plastic or aluminum) and a heavy mallet handy. Remove
dirt, stones, loose bark, nails, staples, and wire from the tree
where the felling cuts are to bemade.
• Notching Undercut - Make the notch 1/3 of the diameter
of the tree, perpendicular to the direction of the fall. Make
the lower horizontal notching cut first. This will help to avoid
pinching of either the saw chain or the guide bar when the
second notch cut is being made as shownbelow.
• Felling Back Cut - Make the felling back cut at least 51mm
higher than the horizontal notching cut. Keep the felling
back cut parallel to the horizontal notching cut. Make the
felling back cut so enough wood is left to act as a hinge.
The hinge wood keeps the tree from twisting and falling
in the wrong direction. Do not cut through the hinge as
shownbelow.
• As the felling cut gets close to the hinge the tree should
begin to fall. If there is any chance that the tree may not fall
in the desired direction or it may rock back and bind the saw
chain, stop cutting before the felling cut is complete and
1. To turn the unit on, push down on the the lock off lever2,
shown in Fig.J, and squeeze the trigger switch1. Once the
unit is running, you may release the lock offlever.
2. In order to keep the unit running you must continue to
squeeze the trigger. To turn the unit off, release thetrigger.
NOTE: If too much force is applied while making a cut the
saw will turn off. To restart saw, you must release the trigger
switch1 before the saw will restart. Begin your cut again this
time with less force. Allow the saw to cut at its ownpace.
WARNING: Never attempt to lock a switch in the
ONposition.

Optional Accessories
WARNING: Since accessories, other than those offered
by PROTODeWALTFATMAX, have not been tested with
this product, use of such accessories with this tool
could be hazardous. To reduce the risk of injury, only
PROTODeWALTFATMAX recommended accessories should
be used with thisproduct.
Consult your dealer for further information on the
appropriateaccessories.
D
Cleaning
WARNING: Blow dirt and dust out of the main housing
with dry air as often as dirt is seen collecting in and around
the air vents. Wear approved eye protection and approved
dust mask when performing thisprocedure.
WARNING: Never use solvents or other harsh chemicals
for cleaning the non‑metallic parts of the tool. These
chemicals may weaken the materials used in these parts.
Use a cloth dampened only with water and mild soap.
Never let any liquid get inside the tool; never immerse any
part of the tool into aliquid.
C
Lubrication
Your power tool requires no additionallubrication.
Saw Chain Sharpness
CAUTION: Sharp chain. Always wear protective gloves
when handling the chain. The chain is sharp and can cut
you when it is notrunning.
IMPORTANT: The chain cutters will dull immediately if they
touch the ground, stones, masonry or a nail whilecutting.
To get the best possible performance from your chain saw it
is important to keep the teeth of the saw chain sharp. Chain
sharpening services are available from your nearest DeWALT
servicecenter.
NOTE: Each time the saw chain is sharpened, it loses some
of the reduced kickback qualities and extra caution should be
used. It is recommended that a saw chain be sharpened no
more than fourtimes.
MAINTENANCE
Your power tool has been designed to operate over a long
period of time with a minimum of maintenance. Continuous
satisfactory operation depends upon proper tool care and
regularcleaning.
WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect battery pack
before making any adjustments or removing/
installing attachments or accessories. An accidental
start‑up can causeinjury.
The charger and battery pack are notserviceable.
2. Place the bottom spike23 of the chainsaw behind the area
of the initial cut as shownbelow.
3. Turn the chainsaw on then rotate the saw chain and bar
down into the tree, using the spike as ahinge.
4. Once the chainsaw gets to a 45° angle, level the chainsaw
again and repeat steps until you cut fullythrough.
5. When the tree is supported along its entire length, make a
cut from the top (overbuck), but avoid cutting the earth as
this will dull your sawquickly.
CUT FROM TOP (OVERBUCK)

• When on a slope always stand on the uphill side of the
log. When “cutting through”, to maintain complete control
reduce the cutting pressure near the end of the cut without
relaxing your grip on the chain saw handles. Don’t let the
chain contact the ground. After completing the cut, wait
for the saw chain to stop before you move the chain saw.
Always stop the motor before moving from cut tocut.
