ENGLISH
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 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 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 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.

General Chain Saw Safety Warnings
WARNING: Additional safety warnings
forchainsaws.
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. Saw chains contacting a "live" wire may make
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 behavior 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 265°F (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.
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.
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

ENGLISH
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 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, 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 bars and chains specified
by the manufacturer. Incorrect replacement bars and
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.
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 of the guidebar.
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
exposed metal parts of the chain saw "live" and could
give the operator an electricshock.
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 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
fibers 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 scabbard. 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.
k ) Cut wood only. Do not use chain saw for purposes
not intended. For example: do not use chain
saw for cutting plastic, masonry or non‑wood
building materials. Use of the chain saw for
operations different than intended could result in a
hazardoussituation.
l ) This chain saw is not intended for tree felling.
Use of the chain saw for operations different than
intended could result in serious injury to the operator
or bystanders.
m) Follow all instructions when clearing jammed
material, storing or servicing the chain saw.
Make sure the switch is off and the battery pack is
removed. Unexpected actuation of the chain saw while
clearing the jammed material or servicing may result in
serious personalinjury.
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.

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

B175.1–2012.
• Do not operate chain saw while 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. 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

2. Insert and fully seat battery pack20. The red charging
light(s) will continuously blink whilecharging.
3. Charging is complete when the red charging light(s)
remain(s) continuously ON. Battery pack can be left in
charger or removed. Some chargers require the battery
pack release button 21 to be pressed forremoval.
WARNING:
Only charge batteries in air temperature over
104° F (40° C) and below 40° F (4.5 °C).
4. Charger will not charge a faulty battery pack, which may
be indicated by the charging light(s) staying OFF. Take
charger and battery pack to an authorized service center
if light(s) stay(s)OFF.
NOTE: Refer to label near charging light(s) on charger
for blinkpatterns. Older chargers may have additional
information and/or may not have a yellow indicatorlight.
NOTE: To remove the battery pack, some chargers
require the battery pack release button to bepressed.
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 may charge at a slower rate than a warm
batterypack.
The hot/cold pack delay will be indicated by the red light(s)
continuing to blink but with the yellow light continuously
ON. Once the battery pack has reached an appropriate
temperature, the yellow light will turn OFF and the charger
will resume the chargingprocedure.
Fan-Cooled Chargers
Some chargers are 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
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 and the battery pack will need to berecharged.
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 – 75°F (18°C– 24°C). DO NOT charge
when the battery pack is 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.
• 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 heavier the cord and
thus the greater its capacity. An undersized cord will
cause a drop in line voltage resulting in loss of power and
overheating. The following table shows the correct size
to use depending on total length of all extension cords
plugged together, and nameplate ampere rating. If in
doubt, use the next heaviergauge.

5. Wearing protective gloves, grasp the saw chain and
guidebar and lift them away from the tool.
6. Wearing protective gloves, use a clean, soft bristle brush
to wipe away any saw dust or other debris that may
have collected on the guide bar11 and around the saw
chain12.
7. Install the chain, guide bar and sprocket cover13
as described in Installing the Guide Bar and Saw
Chain, Replacing the Saw Chainsections and adjust
chain tension properly before use as described in
theAdjustingChain Tensionsection.
Saw Chain and Guide Bar
After every few hours of use, remove the sprocket cover,
guide bar and chain and clean thoroughly using a soft bristle
brush. Ensure oiling hole on bar is clear of debris. When
replacing dull chains with sharp chains it is good practice to
flip the chain bar from bottom totop.
Cleaning
WARNING: Blow dirt and dust out of all air vents with
clean, dry air at least once a week. To minimize the risk
of eye injury, always wear ANSI Z87.1 approved eye
protection 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 plastic 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.
MAINTENANCE
WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack
before making any adjustments or removing/
installing attachments or accessories. An
accidental start‑up can causeinjury.
Your DeWALT 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.
Blocking
Removing sections from a standing tree
Before blocking is started have wedges (wood, plastic or
aluminum) and a heavy mallet handy. Remove loose bark,
nails, staples, and wire from the tree where the blocking cuts
are to bemade.
Conventional Notch
• Notching Undercut - Cut the notch 25% of the diameter
of the tree block, perpendicular to the direction of the
fall. Make the lower horizontal notching cut first as shown
below. This will help to avoid pinching of either the saw
chain or the guide bar when the second notch cut is
being made. Consider conditions such as wind, tree lean,
slope of the ground that could effect the direction of fall.
• Back Cut - Cut the back cut at the same level as the first
horizontal notching cut. Keep the back cut parallel to the
horizontal notching cut as shown below. Make the back
cut so approximately 10% of the tree block remains to act
as a hinge as shown below. The hinge wood keeps the
tree block from falling in the wrong direction. Do not cut
through the hinge.
• As the felling cut gets close to the hinge the tree block
should begin to fall. If there is any chance that the tree
block may not fall in the desired direction or it may rock
back and bind the guide bar, stop cutting before the felling
cut is complete and use wedges to open the cut and drop
the tree block along the desired line of fall. When the tree
block begins to fall remove the chain saw from the cut,
release the trigger switch and activate the chain brake.

WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack
before making any adjustments or removing/
installing attachments or accessories. An
accidental start‑up can causeinjury.
Your tool is Tool Connect™ Chip ready and has a location for
installation of a Tool Connect™ Chip.
Tool Connect™ Chip is an optional application for your smart
device (such as a smart phone or tablet) that connects
the device to utilize the mobile application for inventory
management functions.
Refer to Tool Connect™Chip Instruction Sheet for
moreinformation.
Installing the Tool Connect™ Chip
1. Remove the retaining screws32 that hold the Tool
Connect™ Chip protective cover31 into thetool.
2. Remove the protective cover and insert the Tool
Connect™ Chip into the empty pocket30.

furtherinstructions.
It is recommended that a saw chain be sharpened no more
than fourtimes.
NOTE: The cutters will dull immediately if they touch the
ground/dirt or a nail whilecutting.
To get the best possible performance from your chainsaw it
is important to keep the teeth of the saw chain sharp. Follow
these helpful tips for proper saw chain sharpening:
1. For best results use a 5/32" (4 mm) file and a file holder
or filing guide to sharpen your saw chain. This will ensure
you always get the correct sharpeningangles.
2. Place the file holder flat on the top plate and depth
gauge of thecutter.
3. Keep the correct top plate33 filing angle line of 30° on
your file guide parallel with your chain (file at 60° from
chain viewed from the side) as shownin Fig. T.
4. Sharpen cutters on one side of the chain first. File from
the inside of each cutter to the outside. Then turn your
saw around and repeat the processes (2, 3, 4) for cutters
on the other side of thechain.
NOTE: Use a flat file to file the tops of the rakers (portion
of chain link in front of the cutter) so they are about .025"
(.635 mm) below the tips of the cutters as shownin Fig. S.
5. Keep all cutter lengthsequal as shownin Fig. U.
6. If damage is present on the chrome surface of the
top plates or side plates, file back until such damage
isremoved.
CAUTION: After filing, the cutter will be sharp, use
extra caution during thisprocess.
Saw Chain Sharpening (Fig.S–U)
CAUTION: Sharp chain. Always wear protective gloves
when handling the chain. The chain is sharp and can
cut you when it is notrunning.
WARNING: Sharp moving chain. To prevent accidental
operation, ensure that battery is removed from the tool
before performing the following operations. Failure to
do this could result in serious personalinjury.
WARNING: Do not over file chain rakers, this will
increase the risk of kickback. If the chain has been
sharpened more than four times, replaceit.
Each time the chain is sharpened, it loses some of the low
kickback qualities and extra caution should beused.
