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.
5
ENGLISH
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.
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.
6
ENGLISH
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 authorised serviceproviders.
Pruner Safety Warnings
a ) Keep all parts of the body away from the saw chain
when the pruner is operating. Before you start the
pruner, make sure the saw chain is not contacting
anything. A moment of inattention while operating
pruners may cause entanglement of your clothing or body
with the sawchain.
b ) Always hold the pruner with your right hand on the
rear handle and your left hand on the front handle.
Holding the pruner with a reversed hand configuration
increases the risk of personal injury and should never
bedone.
c ) Hold the pruner by insulated gripping surfaces only,
because the saw chain may contact hidden wiring.
Saw chains contacting a "live" wire may make exposed
metal parts of the pruner "live" and could give the operator
an electricshock.
d ) Wear safety glasses and hearing protection. Further
protective equipment for, head, hands, legs and
feet is recommended. Adequate protective clothing will
reduce personal injury from flying debris or accidental
contact with the sawchain.
e ) Do not operate a pruner saw in a tree, on a ladder,
from a rooftop, or any unstable support. Operation
of a pruner saw in this manner could result in serious
personal injury.
f ) Always keep proper footing and operate the pruner
only when standing on fixed, secure and level
surface. Slippery or unstable surfaces may cause a loss of
balance or control of the pruner.
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 pruner out ofcontrol.
h ) Use extreme caution when cutting brush and
saplings. The slender material could catch the saw chain
and be whipped toward you or pull you offbalance.
i ) Carry the pruner with the pruner switched off and
away from your body. When transporting or storing
the pruner always fit the guide bar cover. Proper
handling of the pruner will reduce the likelihood of
accidental contact with the moving sawchain.
j ) Follow instructions for lubricating, chain tensioning
and changing the bar and saw chain. Improperly
tensioned or lubricated chain could break the
prunerchain.
k ) Keep handles dry, clean, and free from oil
andgrease. Greasy, oily handles are slippery,
causing loss ofcontrol.
l ) Cut wood only. Do not use pruner for purposes not
intended. For example: do not use pruner for cutting
metal, plastic, masonry or non‑wood building
materials. Use of the pruner for operations different than
intended could result in a hazardoussituation.
m ) Maintain a firm grip, with thumbs and fingers
encircling the pruner handles, with both hands on
the pruner. Maintaining control of the pruner will
reduce the risk of losing control. Do not let go of the
pruner.
n ) Do not overreach and do not cut above shoulder
height. This enables better control of the pruner in
unexpected situations.
o ) Only use replacement bars and chains specified
by the manufacturer. Incorrect replacement bars and
chains can cause chain breakage and increase the risk
of injury.
p ) Follow the manufacturer's sharpening and
maintenance instructions for the pruner chain.
Decreasing the depth gauge height can lead to increased
risk of injury.
q ) This pruner is not intended for tree felling. Use of the
pruner for operations different than intended could result
in serious injury to the operator or bystander.
r ) Follow all instructions when clearing jammed
material, storing or servicing the pruner saw. Make
sure the switch is off and the battery pack is removed.

ENGLISH
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
pruner 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 pruner 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 pruner.
b ) Do not overreach and do not cut above
shoulder height. This helps prevent unintended tip
contact and enables better control of the pruner 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 pruner firmly with both hands
when the motor is running. Use a firm grip with thumbs
and fingers encircling the pruner handles. Pruner 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 saw chains specified by
the manufacturer or theequivalent.
8 . Never let the moving saw 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 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 the ribbed bumpers 21 onto the wood and allow the
chain to reach full speed before proceeding witha 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 pruner 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 pruners.
Low‑Kickback Chain, designed with a contoured depth gauge
and guard link which deflects kickback force and allows 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 pruner 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.
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 pruner, make sure saw chain is not contacting
anyobject.
Do not operate a pruner with one hand! Serious injury to the
operator, helpers, or bystanders may result from one‑handed
operation. A pruner 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 pruner 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.

Charging a Battery (Fig.B)
NOTE: To ensure maximum performance and life of lithium‑ion
battery packs, charge the battery pack fully before firstuse.
1. Plug the charger into an appropriate outlet before inserting
batterypack.
2. Insert the battery pack 16 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 Stage 1charging blink indicator represents the
charge process that charges the majority of the battery's
capacity. Stage2charging blink indicator represents the
remainder, or top off charge process, for the battery to reach
fullcapacity.
4. The completion of charge for Stage 1or Stage 2will be
indicated by the stage's light remaining ON continuously.
The battery pack is fully charged when both Stage1and
Stage 2charging lights remain ON continuously, and it may
be removed and used at this time or left in thecharger.
NOTE: To remove the battery pack, some chargers require the
battery pack release button 17 to bepressed.
Refer to the indicators below for the charge status of the
batterypack.
Indicators
Stage 1Charging
Stage 2Charging
Fully Charged
Hot/Cold Pack Delay*
* 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.

will stand upright on the battery pack but may be easily
knockedover.
Transportation
WARNING: Fire hazard. Transporting batteries can
possibly cause fire if the battery terminals inadvertently
come in contact with conductive materials. When
transporting batteries, make sure that the battery
terminals are protected and well insulated from
materials that could contact them and cause a short
circuit. NOTE: Lithium‑ion batteries should not be put in
checkedbaggage.
DeWALT batteries comply with all applicable shipping
regulations as prescribed by industry and legal standards which
include UN Recommendations on the Transport of Dangerous
Goods; International Air Transport Association (IATA) Dangerous
Goods Regulations, International Maritime Dangerous Goods
(IMDG) Regulations, and the European Agreement Concerning
The International Carriage of Dangerous Goods by Road
(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.
11
ENGLISH
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 Watt Hour rating marked on
the pack. Furthermore, due to regulation complexities, DeWALT
does not recommend air shipping lithium‑ion battery packs
alone regardless of Watt Hour rating. Shipments of tools with
batteries (combo kits) can be air shipped as excepted if the Watt
Hour 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 (20V Max) product, it will operate as an 18V
(20V Max) battery. When the FLEXVOLTTM battery is in a 54V
(60V Max) or a 108V (120V Max) (two 54V (60V Max)batteries)
product, it will operate as a 54V(60V Max) 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 excess 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.
Example of Use and Transport Label Marking
NOTE: Battery packs should not be stored completely depleted
of charge. The battery pack will need to be recharged beforeuse.

Common Cutting Techniques
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 pruner as shown below. Trim limbs from opposite
side keeping tree stem between you and pruner. Never make
cuts with pruner between your legs or straddle the limb to
becut.
Bucking
WARNING: Recommend that first‑time users should
practice cutting on a pruner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 pruner chain running at
fullspeed.
2. Place the ribbed bumper21 of the pruner behind the area
of the initial cut as shownbelow.
3. Turn the pruner on then rotate the pruner chain and bar
down into the tree, using the ribbed bumper as ahinge.
4. Once the pruner gets to a 45° angle, level the pruner 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 prunerquickly.

Saw Chain Sharpening (Fig.L–N)
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.
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 pruner 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 11/64" (4.5 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23 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. L.
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 0.025"
(0.635mm) below the tips of the cutters as shownin Fig. M.
5. Keep all cutter lengthsequal as shownin Fig. N.
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, so use extra
caution during thisprocess.
