PRODUCT SAFETY
GENERAL POWER TOOL
SAFETY WARNINGS
WARNING: Read all safety warnings and
all instructions. Failure to follow the
warnings and instructions 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.
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 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, clothing and
gloves 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.
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 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.
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. 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.

10
Cordless Chainsaw EN
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.
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.
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.
CHAIN SAW SAFETY
WARNINGS
1. 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.
2. 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.
3. Hold the power tool 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.
4. Wear safety glasses and hearing protection.
Further protective equipment for head,
hands, legs and feet is recommended.
Adequate protective clothing will reduce
personal injury by flying debris or accidental
contact with the saw chain.
5. Do not operate a chain saw in a tree.
Operation of a chain saw while up in a tree may
result in personal injury.
6. Always keep proper footing and operate
the chain saw 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 chain saw.
7. 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.
8. 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.
9. 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.
10. Follow instructions for lubricating, chain
tensioning and changing accessories.
Improperly tensioned or lubricated chain may
either break or increase the chance for kickback.
11. Keep handles dry, clean, and free from oil
and grease. Greasy, oily handles are slippery
causing loss of control.
12. 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.
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 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

11
Cordless Chainsaw EN
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.
- 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.
- 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.
Residual risks
Even with the intended use of the appliance there
is always a residual risk, which can not prevented.
According to the type and construction of the
appliance the following potential hazards might
apply:
- Contact with exposed saw teeth of the saw chain
(cutting hazards)
- Access to the rotating saw chain (cutting hazards)
- Unforeseen, abrupt movement of the guide bar
(cutting hazards)
- Flung out of parts from the saw chain (Cutting /
injection hazards)
- Flung out of parts of the work piece
- Skin contact with the oil
- Loss of hearing, if no required ear protection used
during work
SAFETY WARNINGS FOR
BATTERY PACK
a) Do not dismantle, open or shred cells or
battery pack.
b) Do not short-circuit a battery pack. Do not
store battery packs haphazardly in a box or
drawer where they may short-circuit each
other or be short-circuited by conductive
materials. 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.
c) Do not expose battery pack to heat or fire.
Avoid storage in direct sunlight.
d) Do not subject battery pack to mechanical
shock.
e) In the event of battery leaking, do not
allow the liquid to come into contact

made, wash the affected area with copious
amounts of water and seek medical advice.
f) Seek medical advice immediately if a cell or
battery pack has been swallowed.
g) Keep battery pack clean and dry.
h) Wipe the battery pack terminals with a
clean dry cloth if they become dirty.
i) Battery pack needs to be charged before
use. Always refer to this instruction and use
the correct charging procedure.
j) Do not maintain battery pack on charge
when not in use.
k) After extended periods of storage, it may
be necessary to charge and discharge
the battery pack several times to obtain
maximum performance.
l) Battery pack gives its best performance
when it is operated at normal room
temperature (20 °C ± 5 °C).
m) When disposing of battery packs, keep
battery packs of different electrochemical
systems separate from each other.
n) Recharge only with the charger specified by
WORX. Do not use any charger other than
that specifically provided for use with the

original packaging until required for use.
v) Observe the plus (+) and minus (–) marks on
the battery and ensure correct use.
SAVE THESE INSTRUCTIONS
Instructions concerning the proper techniques
for basic felling, limbing, and cross-cutting
1. Felling a tree
When bucking and felling operations are being
performed by two or more persons at the same time,
the felling operations 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
company should be notified immediately.
The chain saw operator should keep on the uphill
side of the terrain as the tree is likely to roll or slide
downhill after it is felled.

12
Cordless Chainsaw EN
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 illustrated in Figure 1.
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.
2. Notching undercut
Make the notch 1/3 the diameter of the tree,
perpendicular to the direction of falls as illustrated in
Figure 1. Make the lower horizontal notching cut (W)
first.This will help to avoid pinching either the saw
chain or the guide bar when the second notch (X) is
being made.
3. Felling back cut
Make the felling back cut (Y) at least 50 mm higher
than the horizontal notching cut as illustrated in
Figure 1. 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 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 (Z) to open the cut and drop the
tree along the desired line of fall ( ).
When the tree begins to fall remove the chain saw
from the cut, stop the motor, put the chain saw
down, then use the retreat path planned ( ). Be
alert for overhead limbs falling and watch your
footing. (See Figure 1)

4. Limbing a tree
Limbing is 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 as illustrated in Figure 2. Branches under
tension should be cut from the bottom up to avoid
binding the chain saw.

5. 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 illustrated in Figure 3, it is cut from the top
(overbuck), avoid contacting ground as this will
greatly reduce the chain sharpness.

When bucking on a slope always stand on the uphill
side of the log, as illustrated in Figure 6. When
“cutting through”, to maintain complete control
release 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 tree to tree.

VIBRATION INFORMATION
Vibration total values (triax vector sum) determined according to EN 60745:
Vibration emission value ah=xxm/s2
uncertainty K=xxm/s²
The declared vibration total value may be used for comparing one tool with another, and may also be used in a
preliminary assessment of exposure.
WARNING:The vibration emission value during actual use of the power tool can differ from the
declared value depending on the ways in which the tool is used dependant on the following examples
and other variations on how the tool is used:
How the tool is used and the materials being cut or drilled.
The tool being in good condition and well maintained.
Using the correct accessory for the tool and ensuring it is sharp and in good condition.
The tightness of the grip on the handles and if any anti vibration accessories are used.
And the tool is being used as intended by its design and these instructions.
This tool may cause hand-arm vibration syndrome if its use is not adequately managed
WARNING: To be accurate, an estimation of exposure level in the actual conditions of use should also
take account of all parts of the operating cycle such as the times when the tool is switched off and when
it is running idle but not actually doing the job.This may significantly reduce the exposure level over the total
working period.
Helping to minimise your vibration exposure risk.
ALWAYS use sharp chisels, drills and blades.
Maintain this tool in accordance with these instructions and keep well lubricated (where appropriate).
If the tool is to be used regularly then invest in anti vibration accessories.
Plan your work schedule to spread any high vibration tool use across a number of days.

INTENDED USE
The chainsaw is intended for sawing of trees, tree
trunks, branches, wooden beams, planks, etc. Cuts
can be sawed with or across the grain.This product is
not suitable for sawing mineral materials.
ASSEMBLY
WARNING! Do not install the battery pack
before it has been completely assembled.
Always use gloves when handling the chain.
CHAIN AND GUIDE BAR ASSEMBLY
1. Unpack all parts carefully. Remove the chain cover
by turning the chain tensioning knob in a counter-
clockwise direction. (See Fig. A1)
2. Place the chainsaw on a solid, level surface.
3. Use only genuine WORX chains or those
recommended for Guide Bar.
4. Slide the chain in the slot around the guide bar.
Ensure the chain is in correct running direction by
comparing it to the chain icon on the guide bar, or
referring to the chain direction symbol found on
the saw body. Ensure the bar tensioning plate is
facing outward. (See Fig. A2)
5. Fit the chain onto the drive sprocket, so that the
fastening bar bolt and the bar locating tab on the
bar pad fit into the keyway of the opening on the
guide bar. (See Fig. B1, B2)
6. Assure all parts are seated properly and hold chain
and guide bar in a level position. Make sure the
drive links are fully seated in the drive sprocket
(See Fig. C1), avoiding a kink as shown in Fig. C2.
If kink occurs, pick up on the chain at the guide bar
just ahead of the kink and then pull the kink out.
NOTE: Chain should rotate freely and be free of
kinks.
7. Fit the chain cover and tighten the chain cover by
turning the chain tensioning knob clockwise until it
is tight. (See Fig. D)
8. The chain will stretch while cutting and lose
proper tension. When the chain becomes loose,
completely unscrew the chain tensioning knob
or turn the knob around three (3) full turns in a
counter-clockwise direction, then retighten the
chain tensioning knob to properly reset the chain
tension by repeating Steps 6-7 listed above.
WARNING: The chain is not yet tensioned.
Tensioning the chain applies as described
under “TENSIONING CHAIN”. The chain
now needs to be inspected to make sure it is
properly tensioned.
TENSIONING CHAIN (See Fig. E1, E2)
NOTE: New saw chains will stretch. Check the chain
tension frequently when first used and tighten when
the chain becomes loose around the guide bar.
WARNING:
●Removing the battery pack before adjusting
saw chain tension.
●Cutting edges on chain are sharp. Use
protective gloves when handling chain.
●Maintain proper chain tension always.
A loose chain will increase the risk of
kickback. A loose chain may jump out of
guide bar groove. This may injure operator
and damage chain. A loose chain will cause
chain, bar, and sprocket to wear rapidly.
1. Place the chainsaw on any suitable flat surface.
2. Turn the chain tensioning knob clockwise until it is
hand tight.
NOTE:The tension is automatically increased
while the chain tensioning knob is being turned
in a clockwise direction.The built-in ratchet
mechanism prevents the chain tension from
loosening.
3. Tilt the saw forward (See E1) where the guide bar
tip is pushed in an downward direction.This will
remove slack from the chain.
4. Fully tighten the chain tensioning knob by turning
it clockwise.
5. Double check the tension set by the automatic
chain tensioning knob.The correct chain tension
is reached when the chain can be raised approx.
Half the drivelink depth (3-5mm) from the guide
bar in the center.This should be done by using one
hand to raise the chain against the weight of the
machine. (See Fig. E2)
NOTE: The chain is properly tensioned when it can be
lifted off of the Guide Bar and the drivelink is within
the rail of the guide bar.
NOTE:The chain will stretch while cutting and lose
proper tension. When the chain becomes loose,
completely unscrew the chain tensioning knob or turn
the knob around three full turns in a counter-clockwise
direction, then retighten the chain tensioning knob to
properly reset the chain tension by repeating Steps 1-4
listed above.
LUBRICATION (See Fig. F)
Important: The chainsaw is not filled with
oil. It is essential to fill with oil before
use. Never operate the chainsaw without
chain oil or at an empty oil tank level, as this
will result in extensive damage to the product.
NOTE: Chain life and cutting capacity depend
on optimum lubrication. Therefore, the chain is
automatically oiled during operation.
Filling oil tank:
WARNING: Removing the battery pack
before filling the oil tank.
1. Set chainsaw on any suitable surface with oil filler
cap facing upward.
2. Clean area around the oil filler cap with cloth and
unscrew the cap by turning it counter clockwise.

3. Add bar and chain oil until tank is full.
4. Avoid dirt or debris entering oil tank, refit oil filler
cap and tighten by turning clockwise until hand
tight.
Important: To allow venting of the oil
tank, small breather channels are
provided between the oil filler cap and
the strainer, to prevent leakage, and ensure
machine is left in a horizontal position when
not in use.
It is important to use only the recommended
standard bar and chain oil (Grade: ISO VG32)
to avoid damage to the chainsaw. This can be
found at the location where you purchased this
saw or your local hardware store. Never use
recycled/old oil. Use of non approved oil will
void the warranty.
Do not swallow. If swallowed, call a physician
immediately. Keep out of reach of children.
Store away from heat or open flame.
Checking the Automatic Oiler
Proper functioning of the automatic oiler can be
checked by running the chainsaw and pointing the tip
of the guide chain bar towards a piece of cardboard
or paper on the ground. If an increasing oil pattern
develops on the cardboard, the automatic oiler is
operating fine. If there is no oil pattern, despite a full
oil reservoir, contact WORX customer service agent or
WORX approved service agent.
CAUTION: Do not touch the ground with
the chain. Ensure safety clearance of 30
cm.
OPERATION
1. BEFORE USING YOUR CORDLESS TOOL
WARNING!The charger and battery pack are
specially designed to work together so do not
attempt to use any other devices. Never insert
or allow metallic objects into your charger or battery
pack connections because of an electrical failure and
hazard will occur.
NOTE: Your battery pack is UNCHARGED and you
must charge once before use.

Note:
● When removing the battery pack, hold it
firmly to avoid dropping and injury.
● This machine will only run when 2 batteries
are installed. It is recommended to use the
same two batteries and charge the two
batteries at the same time.
● When you use two batteries with different
power, the machine will only run to the
lower common denominator.
5. POWER INDICATOR LIGHT (See Fig. J)
IMPORTANT:
When only one light is illuminated, your battery
is overly discharged, even though the machine
may still be capable to work. Continuing to
operate your machine with the battery in this

battery pack listed in the accessories section.
For switching on the tool, press the lock-out button,
then fully press the on/off switch and hold in this
position.The lock-out button can now be released.
For switching off, release the on/off switch.
NOTE: The chain brake must be activated in order for
the saw to be switched on.
7. CHAIN BRAKE LEVER (See fig. L)
The chain brake lever is a safety mechanism activated
through the front hand guard, when kickback occurs.
Chain stops immediately.
The following function check should be carried out at
regular intervals. Pull the front hand guard towards
the operator (position ) to deactivate chain brake.
To activate the chain brake, push front hand guard
forwards (position ).
Note: If the saw is unable to start, even though it is
assembled properly and working with fully charged
battery packs, then you should check if the chain brake
lever is in the correct position (position ).
8. CUTTING
Important: Is the oil tank filled? Check the
Oil Level Window prior to starting and
regularly during operation (See Fig. M). Refill oil
when oil level is low. A full oil tank will last
approx. 12 minutes of cutting depending on
sawing intensity and stops.
Check recent replaced chain tension about
every 10 minutes during operation.
(1) Installing the battery pack into the machine.
(2) Make sure section of log to be cut is not laying on
the ground.This will keep the chain from touching
the ground as it cuts through the log.
Touching the ground while the chain is moving is
dangerous and will dull the chain.
(3) Use both hands to grip saw. Always use left hand
to grip front handle and right hand to grip rear
handle. Use a firm grip.Thumbs and fingers must
wrap around saw handles. (See Fig. N)
(4) Make sure your footing is firm. Keep feet-shoulder
width apart. Distribute your weight evenly on both
feet.
(5) When ready to make a cut, push the lock-out
button completely in with the right thumb
and squeeze the trigger.This will turn saw on.
Releasing the trigger will turn the saw off. Make
sure the saw is running at full speed before
starting a cut.
(6) When starting a cut, slowly place moving chain
against the wood.The wood should be as close to
the saw body as possible. Hold saw firmly in place
to avoid possible bouncing or skating (sideways
movement) of saw.
(7) Guide the saw using light pressure and do not put
excessive force on the saw, letting the saw do its
work.The motor will overload and can burn out. It
will do the job better and safer at the rate for which
it was intended.
(8) Remove the saw from a cut with the saw running
at full speed. Stop the saw by releasing the on/off
switch. Make sure the chain has stopped before
setting the saw down.
(9) Keep practicing on scrap logs in a secure working
area until you are comfortable, using a fluid
motion and a steady cutting rate.
Kickback Safety Devices On This Saw
This saw has a low-kickback chain and reduced
kickback Guide Bar. Both items reduce the chance of
kickback. However, kickback can still occur with this
saw.
The following steps will reduce the risk of kickback.
• Use both hands to grip saw while saw is running.
Use firm grip.Thumbs and fingers must wrap
around saw handles.
• Keep all safety items in place on saw. Make sure
they work properly.
• Do not overreach or cut above shoulder height.
• Keep solid footing and balance at all times.
• Stand slightly to the left side of saw.This keeps
your body from being in direct line with chain.
• Do not let Guide Bar nose touch anything when
chain is moving.
• Never try cutting through two logs at same time.
Only cut one log at a time.
• Do not bury the Guide Bar nose or try plunge cut
(boring into wood using guide bar nose).
• Watch for shifting of wood or other forces that may
pinch chain.
• Use extreme caution when reentering a previous
cut.
• Use only the low-kickback chain and guide
bar that were supplied with this chainsaw or
recommended.
