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
◾Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
◾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.
◾Keep children and bystanders away while
operating a power tool. Distractions can cause you
to lose control.
ELECTRICAL SAFETY
◾Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any adaptor
plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce risk
of electric shock
◾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.
◾Do not expose power tools to rain or wet
conditions. Water entering a power tool will increase
the risk of electric shock.
◾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.
◾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.
◾If operating a power tool in a damp location is
unavoidable, use a Ground-fault circuit interrupter
protected supply. Use of GFCI reduces the risk of
electric shock.
PERSONAL SAFETY
◾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 medication. A
moment of inattention while operating power tools may
result in serious personal injury.
◾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.
◾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.
◾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.

56 VOLT LITHIUM-ION CORDLESS CHAIN SAW — CS2000E10
◾Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations.
◾Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewelry or long hair
can be caught in moving parts.
◾If devices are provided for the connection of dust
extraction and collection facilities, ensure these
are connected and properly used. Use of dust
devices can reduce dust-related hazards.
◾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
◾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.
◾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.
◾Disconnect the plug from the power source and/
or the battery pack 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.
◾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.
◾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.
◾Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
◾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.
◾Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles and
grasping surfaces may lead to unsafe handling and/or
loss of control of the tool.
BATTERY TOOL USE AND CARE
◾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.
◾Use power tools only with specifically designated
battery packs. Use of any other battery packs may
create a risk of injury and fire.
◾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.
◾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.
◾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.
◾Do not expose a battery pack or tool to fire or
excessive temperature. Exposure to fire or temperature
above 130°C may cause explosion.
◾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.
SERVICE
◾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.
◾Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
CHAINSAW SAFETY WARNINGS
◾Keep all parts of the body away from the saw chain
when the chainsaw is operating. Before you start the
chainsaw, make sure the saw chain is not contacting
anything. A moment of inattention while operating
chainsaws may cause entanglement of your clothing or
body with the chain.

56 VOLT LITHIUM-ION CORDLESS CHAIN SAW — CS2000E 11
◾Always hold the chainsaw with your right hand
on the rear handle and your left hand on the front
handle. Holding the chainsaw with a reversed hand
configuration increases the risk of personal injury and
should never be done.
◾Hold the chainsaw 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 power tool “live” and could
give the operator an electric shock.
◾Wear eye protection. Further protective equipment for
hearing, head, hands, legs and feet is recommended.
Adequate protective clothing will reduce personal injury by
flying debris or accidental contact with the saw chain.
◾Do not operate a chainsaw in a tree, on a ladder, from
a rooftop, or any unstable support. Operation of a
chainsaw in this manner could result in serious personal
injury.
◾Always keep proper footing and operate the chainsaw
only when standing on fixed, secure and level surface.
Slippery or unstable surfaces such as ladders may cause
a loss of balance or control of the chainsaw.
◾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 chainsaw out of control.
◾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.
◾Carry the chainsaw by the front handle with the
chainsaw switched off and away from your body.
When transporting or storing the chainsaw always fit
the guide bar cover. Proper handling of the chainsaw
will reduce the likelihood of accidental contact with the
moving saw chain.
◾Follow instructions for lubricating, chain tensioning
and changing accessories. Improperly tensioned or
lubricated chain may either break or increase the
chance for kickback.
◾Cut wood only. Do not use chainsaw for purposes
not intended. For example: do not use chainsaw
for cutting plastic, masonry or non-wood building
materials. Use of the chainsaw for operations different
than intended could result in a hazardous situation.
◾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.
◾Follow all instructions when clearing jammed
material, storing or servicing the chainsaw. Make
sure the switch is off and the battery pack is removed.
Unexpected actuation of the chainsaw while clearing
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 (Fig. B).
Tip contact in some cases may cause a sudden reverse
reaction, kicking the guide bar up and back towards the
operator (Fig. C).
Pinching the saw chain along the top of the guide bar
may push the guide bar rapidly back towards the operator
(Fig. D).
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 chainsaw 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:
◾Maintain a firm grip, with thumbs and fingers
encircling the chainsaw handles, with both hands on
the saw and position your body and arm to allow you
to resist kickback forces (Fig. E). Kickback forces can
be controlled by the operator, if proper precautions are
taken. Do not let go of the chainsaw.
◾Do not overreach and do not cut above shoulder
height. This helps prevent unintended tip contact and
enables better control of the chainsaw in unexpected
situations.
◾Only use replacement bars and chains specified by
the manufacturer. Incorrect replacement bars and
chains may cause chain breakage and/or kickback.
◾Follow the manufacturer’s sharpening and
maintenance instructions for the saw chain.
Decreasing the depth gauge height can lead to
increased kickback.
◾Make sure that the area in which you are cutting
is free from obstructions. Do not let the nose of the
guide bar contact a log, branch, fence, or any other
obstruction that could be hit while you are operating
the saw.
◾Always cut with the unit running at full speed. Fully
squeeze the switch trigger and maintain cutting speed.

56 VOLT LITHIUM-ION CORDLESS CHAIN SAW — CS2000E12
◾With a basic understanding of kickback, you can
reduce or eliminate the element of surprise. Sudden
surprise contributes to accidents.
◾Keep proper footing and balance at all times.
◾Push and Pull – The reaction force is always opposite
to the direction the chain is moving where wood
contact is made. Thus, the operator must be ready to
control the PULL when cutting on the bottom edge of
the bar, and the PUSH when cutting along the top edge
(Fig. F).
KICKBACK SAFETY DEVICES ON THIS CHAINSAW
CHAIN BRAKE
The chainsaw comes equipped with a chain brake, which
stops both the motor and the motion of the chain when
kickback occurs. The chain brake can be activated by the
for-ward motion of the chain kickback brake paddle as
the saw rotates backward during kickback; it can also
be activated by the inertial forces generated during rapid
pushback.
WARNING: Never modify or attempt to disable the
chain brake.
Make sure that the chain brake is working properly before
using the chainsaw. The chain kickback brake paddle
should move back and forth easily.
To test the operation of the chain brake, perform the
following steps (Fig. G):
◾Place the chainsaw on a flat bare surface and make
sure no objects or obstructions that could come in
contact with the bar and chain are in the immediate
vicinity.
◾Disengage the chain brake by pulling the chain
kickback brake paddle towards the front handle.
◾Start the chainsaw.
◾Push the chain kickback brake paddle towards the
front of the saw. A properly functioning hand brake
will stop the movement of the chain immediately. If
the chain brake is not working properly, do not use the
chainsaw until it has been repaired by a qualified service
technician.
WARNING: Confirm that the chain brake works
properly before each use.
WARNING: If the chain brake is clogged with wood
chips, the function of the chain brake may deteriorate.
Always keep the device clean.
LOW KICKBACK SAW CHAIN
The rakers (depth gauges) ahead of each cutter can
minimize the force of a kickback reaction by preventing
the cutters from digging in too deeply at the kickback
zone. Only use a replacement chain that is equivalent to
the original chain or has been certified one.
CAUTION: As saw chains are sharpened during their
useful life, they lose some of the low kickback qualities
and extra caution should be used.
ADDITIONAL WARNINGS
◾A chainsaw is intended for two-handed use. Serious
injury to the operator, helpers, and/or bystanders can
result from one-handed operation.
◾Avoid unintentional contact with the stationary
saw chain or guide bar rails.These can be very
sharp. Always wear gloves and long pants or chaps when
handling the chainsaw, saw chain, or guide bar.
◾Never operate a chainsaw that is damaged or
improperly adjusted or that is not completely and
securely assembled. Be sure that the saw chain stops
moving when the trigger switch is released.
◾Inspect the work piece for nails, wire, or other
foreign objects prior to cutting.
◾When bucking, secure the work piece prior to
cutting. When felling or pruning, identify and
secure hazardous branches.
◾Aggressive or abusive cutting or misuse of the
chainsaw can cause premature bar, chain, and/
or sprocket wear, as well as broken chain or bar,
leading to kickback, chain throw or the ejection of
material.
◾Never use the guide bar as a lever. A bent guide bar
can cause premature bar, chain, and/or sprocket wear,
as well as a broken chain or bar, leading to kickback,
chain throw or the ejection of material.
◾Cut only one work piece at a time.
◾Use only with battery packs and chargers listed
below.

◾Plan the work, ensuring an obstacle-free work area
and, in the case of felling, at least one escape path
from the falling tree.
◾When felling, keep bystanders at least two tree
lengths away.
◾If situations occur which are not covered in this
manual, use care and good judgment. Contact EGO

speed mode: one bar for low speed, two bars for medium
speed, and three bars for high speed. The low speed
mode (ECO) provides better control of the machine and
longer operating time per charge.
NOTE: When using EGO battery pack rated 2.5Ah or
less, only the ECO mode is available. And use of EGO
battery pack rated less than 6.0Ah will not allow you to
achieve high speed. For best performance, we strongly
recommend use of EGO battery packs that are 6.0Ah or
more (e.g., BA4200T).
NOTE: The machine’s speed memory function will
remember the last speed setting and activate it the next
time the machine is turned on.
NOTE: The LCD screen lights up when trigger switch is
pulled or when the speed button or headlight/Bluetooth®
button is pressed. It will automatically turn off after
approximately 30 seconds of chainsaw inactivity.

OMNI-DIRECTIONAL CHAIN BRAKE SYSTEM (Fig. U1
and Fig. U2)
WARNING: The omni-directional chain brake system
is not intended to act as a substitute to the standard/
traditional chain brake. The user should never rely on
this feature during operation of the chainsaw to protect
against kickback. Always follow safety instructions related
to kickback mitigation found in the warning section of
this manual.
When the omni-directional chain brake system is
activated and stops the saw, the brake icon will be
flashing on the LCD screen (Fig. S). Release the trigger
switch, remove the saw chain and guide bar from the
wood, then restart the chainsaw.
NOTE: The sensors will only detect sudden motion of the
saw in the plane of the guide bar (fig. U1). The sensors
will not detect any sudden motion of the saw sideways
(fig. U2) (i.e., perpendicular to the plane of the guide bar).
PROPER GRIP ON HANDLES (Fig. V1)
◾Wear non-slip gloves for maximum grip and protection.
◾With the saw on a firm, flat surface, hold the saw firmly
with both hands.
◾Always grasp the front handle with the left hand and
the rear handle with the right hand.
◾The fingers should encircle the handle, with the thumb
wrapped under the front handle.
WARNING: Never use a left-handed (cross-handed)
grip, or any stance which would place your body or arm
across the chain line.
WARNING: Do not operate the trigger switch with
your left hand and hold the front handle with your right
hand. Never allow any part of your body to be in the chain
line while operating a chainsaw (Fig. V2).
PROPER CUTTING STANCE (Fig. V3)
◾Both feet should be on solid ground, with weight evenly
spread between them.
◾The left arm should be straight, with the elbow locked.
This helps to withstand the forces generated by
kickback.
◾Your body should always be to the left of the chain line.
INSTRUCTIONS CONCERNING THE PROPER
TECHNIQUES FOR BASIC FELLING, LIMBING, AND
CROSS-CUTTING
WARNING: Always be sure of your footing and hold
the chainsaw firmly with both hands while the motor is
running.
WARNING: When the saw chain is stopped due
to pinching during cutting, release the trigger switch;
remove the saw chain and guide bar from the wood, then
restart the chainsaw.
WARNING: Do not pull the saw chain with hand
when it is bound by the sawdust. Serious injury could
result if the chainsaw starts accidentally. Press the saw
chain against the wood, move the chainsaw back and
forth to discharge the debris. Always remove the battery
pack before cleaning. Wear heavy protective gloves when
handling the saw chain.
WARNING: Never start the chainsaw when it is in
contact with the wood. Always allow the chainsaw to
reach full speed before applying the saw to the wood.
Felling a tree
◾When bucking and felling operations are being
performed by two or more persons at the same time,
the felling operation should be separated from the
bucking operation by a distance of at least twice the
height of the tree being felled. Trees should not be
felled in a manner that would endanger any person,
strike any utility line or cause any property damage.
If the tree does make contact with any utility line, the
utility company should be notified immediately.
◾The chainsaw operator should stand on the uphill
side of the terrain, as the tree is likely to roll or slide
downhill after it is felled.
◾An escape path should be planned and cleared as
necessary before cuts are started. The escape path
should extend back and diagonally to the rear of the
expected line of fall as Fig. W1 shown.
◾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.
◾Remove dirt, stones, loose bark, nails, staples and wire
from the tree.
Notching undercut
Make the notch 1/3 the diameter of the tree,
perpendicular to the direction of falls as Fig. W2 shown.
Make the lower horizontal notching cut first. This will help
to avoid pinching either the saw chain or the guide bar
when the second notch is being made.
Felling back cut
◾Make the felling back cut at least 50 mm higher than
the horizontal notching cut as Fig. W2 shown. Keep
the felling back cut parallel to the horizontal notching

56 VOLT LITHIUM-ION CORDLESS CHAIN SAW — CS2000E 17
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 the felling gets close to the hinge, the tree should
begin to fall. If there is any chance that the tree may
not fall in desired direction or it may rock back and
bind the saw chain, stop cutting before the felling back
cut is complete and use wedges of wood, plastic or
aluminium 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 a tree
Limbing is removing the branches from a fallen tree.
When limbing, larger lower limbs are left to support the
log off the ground. Remove the small limbs in one cut as
Fig. W3 shown. Branches under tension should be cut
from the bottom up to avoid binding the chainsaw.
Bucking a log
Bucking is cutting a log into lengths. It is important to
make sure your footing is firm and your weight is evenly
distributed on both feet. When possible, the log should be
raised and supported by the use of limbs, logs or chocks.
Follow the simple directions for easy cutting.
◾When the log is supported along its entire length as
Fig. X1 shown, it is cut from the top (overbuck).
◾When the log is supported on one end, as Fig. X2
shown, cut 1/3 the diameter from the underside
(underbuck). Then make the finished cut by
overbucking to meet the first cut.
◾When the log is supported on both ends, as Fig. X3
shown, cut 1/3 the diameter from the top (overbuck).
Then make the finished cut by underbucking the lower
2/3 to meet the first cut.
◾When bucking on a slope, always stand on the uphill
side of the log, as Fig. Y shown.
◾When “cutting through”, to maintain complete control,
release the cutting pressure near the end of the cut
without relaxing your grip on the chainsaw handles.
Don’t let the chain contact the ground. After completing
the cut, wait for the saw chain to stop before you move
the chainsaw. Always stop the motor before moving
from tree to tree.
MAINTENANCE
WARNING: When servicing, use only identical
replacement parts. Use of any other parts may create a
hazard or cause product damage. To ensure safety and
reliability, all repairs should be performed by a qualified
service technician.
WARNING: To avoid serious personal injury, remove
the battery pack from the chainsaw before inspecting,
cleaning, or performing maintenance. A battery operated
tool with the battery pack inserted is always on and can
start accidently.
WARNING: When cleaning the chainsaw, DO NOT
immerse it in water or other liquids.
WARNING: Do not at any time let brake fluids,
petrol, petroleum-based products, penetrating oils,
etc., come in contact with plastic parts. Chemicals can
damage, weaken, or destroy plastic, which may result in
serious personal injury.
CLEANING
◾After each use, clean debris from the chain and guide
bar with a soft brush. Wipe the chainsaw surface with
a clean cloth moistened with a mild soap solution.
◾Remove the side cover, and then use a soft brush to
remove debris from the guide bar, saw chain, sprocket
and side cover.
◾Always clean out wood chips, saw dust, and dirt from
the guide bar groove when replacing the saw chain.
GUIDE BAR MAINTENANCE
When the guide bar shows signs of wear, disassemble
it from the chainsaw power head and reverse it for
reassembly (Fig. Z1). This way the wear will be distributed
to maximize the guide bar life.
The bar should be cleaned every day of use and checked
for wear and damage. Feathering or burring of the bar
rails is a normal process of bar wear. Such faults should
be smoothed with a file as soon as they occur. A bar with
any of the following faults should be replaced.
◾Wear inside the bar rails which permits the chain to lay
over sideways.
◾Bent guide bar.
◾Cracked or broken rails.
◾Spread rails.

56 VOLT LITHIUM-ION CORDLESS CHAIN SAW — CS2000E18
In addition, the guide bar has a sprocket at its tip (Fig.
Z2). The sprocket must be lubricated weekly with a
grease syringe to extend the guide bar life. Use a grease
syringe to lubricate weekly with chain oil by means of the
lubricating hole (Fig. Z3). Turn the guide bar and check
that the lubrication holes and chain groove are free from
impurities.
CHAIN MAINTENANCE
Use only low-kickback chains on this saw. This fast
cutting chain will provide kickback reduction when
properly maintained.
A properly sharpened saw chain cuts through wood
effortlessly, even with very little pressure. Never use a
dull or damaged saw chain. A dull saw chain cutter leads
to increased physical strain, increased vibration load,
unsatisfactory cutting results, and increased wear.
For smooth and fast cutting, the chain needs to be
maintained properly. The chain requires sharpening when
the wood chips are small and powdery, the chain must be
forced through the wood during cutting, or the chain cuts
to one side. During maintenance of your chain, consider
the following:
◾Improper filing angle of the side plate can increase the
risk of a severe kickback.
◾Depth gauge clearance. Too low increases the potential
for kickback. Not low enough decreases cutting ability.
◾If cutter teeth have hit hard objects, such as nails and
stones, or have been abraded by mud or sand on the
wood, have the chain sharpened by a qualified service
technician.
TRANSPORTING AND STORING
◾Do not store or transport the chainsaw when it is
running. Always remove the battery pack before
storing or transportation.
◾Always place the chain sheath on the guide bar and
chain before storing or transporting the chainsaw. Use
with caution to avoid the sharp teeth of the chain.
◾Clean the chainsaw thoroughly before storing. Store
the chainsaw indoors, in a dry place that is locked and/
or inaccessible to children.
◾Keep away from corrosive agents such as garden
chemicals and de-icing salts.
PROTECTING THE ENVIRONMENT
Do not dispose of electrical appliances
as unsorted municipal waste, use
separate
Contact your local government for
information regarding the collection
systems available.
If electrical appliances are disposed
of in landfills or dumps, hazardous
substances can leak into the
groundwater and get into the food
chain, damaging your health and
well-being.
