PRODUCT SAFETY

WARNING: Some dust created by

power sanding, sawing, grinding, drilling

and other construction activities contains

chemicals known to the state of California

to cause cancer, birth defects or other

reproductive harm. Some examples of these

chemicals are:

• Lead from lead-based paints;

• Crystalline silica from bricks and cement

and other masonry products;

• Arsenic and chromium from chemically-

treated lumber.

Your risk from these exposures varies,

depending on how often you do this type

of work. To reduce your exposure to these

chemicals: work in a well ventilated area, and

work with approved safety equipment, such as

those dust masks that are specially designed

to ﬁlter out microscopic particles.

WARNING: This product can expose you

to chemicals including lead and Di(2-

ethylhexyl)phthalate (DEHP) which are known

to the State of California to cause cancer and

birth defects or other reproductive harm. For

more information go to www.P65Warnings.

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.

Cordless Chainsaw EN

3

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.

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

Cordless Chainsaw EN

4

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

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.

SAFETY WARNINGS FOR

BATTERY PACK

a) Do not dismantle, open or shred battery

pack.

b) Do not expose battery pack to heat or ﬁre.

Avoid storage in direct sunlight.

c) 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.

d) Do not remove battery pack from its

original packaging until required for use.

e) Do not subject battery pack to mechanical

shock.

f) In the event of battery leaking, do not

allow the liquid to come into contact

with the skin or eyes. If contact has been

made, wash the affected area with copious

amounts of water and seek medical advice.

g) Observe the plus (+) and minus (–) marks on

the battery back and equipment and ensure

correct use.

h) Do not use any battery pack which is not

designed for use with the equipment.

i) Keep battery pack out of the reach of

children.

j) Seek medical advice immediately if a cell or

battery pack has been swallowed.

k) Always purchase the battery pack

recommended by the device manufacturer

for the equipment.

l) Keep battery pack clean and dry.

m) Wipe the battery pack terminals with a

clean dry cloth if they become dirty.

n) Battery pack needs to be charged before

use. Always use the correct charger and

refer to the manufacturer’s instructions

or equipment manual for proper charging

instructions.

o) Do not leave battery pack on prolonged

charge when not in use.

p) After extended periods of storage, it may

be necessary to charge and discharge

the battery pack several times to obtain

maximum performance.

q) Battery pack gives its best performance

when it is operated at normal room

temperature (20 °C ± 5 °C).

r) When disposing of battery packs, keep

battery packs of different electrochemical

systems separate from each other.

s) Recharge only with the charger speciﬁed

by Worx. Do not use any charger other than

that speciﬁcally provided for use with the

equipment. A charger that is suitable for one

type of battery pack may create a risk of ﬁre when

used with another battery pack.

t) Retain the original product literature for

future reference.

u) Use only the battery pack in the application

for which it was intended.

v) Remove the battery from the equipment

when not in use.

w) Dispose of properly.

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

Cordless Chainsaw EN

5

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.

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.

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.

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 tabs 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 (3) 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 bar and chain lubricant

(not provided) that is formulated to perform

over a wide temperature range with no

dilution required. This can be found at the

location where you purchased this saw or

your local hardware store. Do not use dirty,

used or otherwise contaminated oils. Damage

may occur to the bar or chain. 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

12”.

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

Cordless Chainsaw EN

18

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.

• Never use a dull or loose chain. Keep chain sharp

with proper tension.

How to use Saw Safely

1. Use the chainsaw only with secure footing.

2. Hold the chainsaw at the right-hand side of your

body (See Fig. O).

3. The chain must be running at full speed before it

makes contact with the wood.

4. Use the bumper spikes to secure the saw onto

the wood before starting to cut.

5. Use the Bumper Spikes as a leverage point while

cutting. (See Fig. P)

6. Do not operate the chainsaw with arms fully

extended, attempt to saw areas which are difﬁcult

to reach, or stand on a ladder while sawing (See

Fig. Q).

Never use the chainsaw above shoulder height

CUTTING WOOD UNDER TENSION (SEE FIG. R)

WARNING: When cutting a limb that is

under tension, use extreme caution. Be

alert for wood springing back. When wood

tension is released, limb could spring back and

strike operator causing severe injury or death.

When sawing logs supported on both ends, start

the cut from above(Y) about 1/3 of the diameter into

the log (overbuck) and then ﬁnish the cut (Z) from

below, in order to avoid contact of the chainsaw with

the ground. When sawing logs supported on only

one end, start the cut from below (Y) about 1/3 of

the diameter into the log (underbuck) and ﬁnish the

cut from above (Z) in order to avoid log splitting or

jamming of the chainsaw.

SAW MAINTENANCE

Follow maintenance instructions in this manual.

Proper cleaning of saw and chain and guide bar

maintenance can reduce chances of kickback. Inspect

and maintain saw after each use. This will increase the

service life of your saw.

Note: Even with proper sharpening, risk of kickback

can increase with each sharpening.

MAINTENANCE AND

STORAGE OF CHAINSAW

1. Remove the battery pack

• When not in use

• Before moving from one place to another

• Before servicing

• Before changing accessories or attachments, such

as saw chain and guard

2. Inspect chainsaw before and after each use.

Check saw closely if guard or other part has been

damaged. Check for any damage that may affect

operator safety or operation of saw. Check for

alignment or binding of moving parts. Check for

broken or damaged parts. Do not use chainsaw if

damage affects safety or operation. Have damage

repaired by authorized service center. To locate an

authorized service center, visit www.worx.com.

3. Maintain chainsaw with care.

• Never expose saw to rain or direct moisture.

• Keep chain sharp, clean, and lubricated for better

and safer performance.

• Follow steps outlined in this manual to sharpen

chain.

• Keep handles dry, clean, and free of oil and

grease.

• Keep all screws and nuts tight.

4. When servicing, use only identical replacement

parts.

5. When not in use, always store chainsaw

• in a high or locked place, out of children’s reach

Cordless Chainsaw EN

19

• in a dry place

• with bar and chain cover in place

Bar Maintenance

To maximize bar life, the following bar maintenance

is recommended.

The bar rails that carry the chain should be cleaned

before storing the tool or if the bar or chain appear

to be dirty.

The rails should be cleaned every time the chain is

removed.

To clean the Bar rails.

1. Remove chain cover and bar and chain. (see

section ASSEMBLY)

2. Using a wire brush, screwdriver or similar tool,

clear the residue from the inner groove of the bar.

(See Fig. S)

3. Make sure to clean oil passages thoroughly

Conditions which require chain and guide bar

maintenance:

• Saw cuts to one side or at an angle.

• Saw has to be forced through the cut.

• Inadequate supply of oil to the bar and chain.

Check the condition of the guide bar each time the

chain is sharpened. A worn guide bar will damage

the chain and make cutting difﬁcult.

After each use, remove the battery pack, clean all

sawdust from the guide bar and sprocket hole.

When rail top is uneven, use a ﬂat ﬁle to restore

square edges and sides.

File Rail Edges

and Sides

Square

Worn Groove Correct Groove

Replace the guide bar when the groove is worn, the

guide bar is bent or cracked, or when excess heating

or burring of the rails occurs. If replacement is

necessary, use only the Guide Bar speciﬁed for your

saw in the repair parts list or on the decal located on

the chainsaw.

Replacing Bar & Chain

Replace chain when cutters are too worn to sharpen

or when chain stops. Only use replacement chain

noted in this manual.

Inspect guide bar before sharpening chain. A worn

or damaged guide bar is unsafe. A worn or damaged

guide bar will damage chain. It will also make cutting

harder.

Fit the bar tensioning plate tab into the new bar by

tightening the screw clockwise. The tab protrusion (a)

must be ﬁtted into the bar hole. (See Fig. T)

SHARPENING SAW CHAIN

WARNING: Remove the battery pack

before servicing. Severe injury or death

could occur from electrical shock or body

contact with moving chain.

Cutting edges on chain are sharp. Use

protective gloves when handling chain.

Keep chain sharp. Your saw will cut faster and more

safely. A dull chain will cause undue sprocket, Guide

Bar, chain, and motor wear. If you must force chain

into wood and cutting creates only sawdust with few

large chips, chain is dull.

LUBRICATE SPROCKET

WARNING: Wear heavy duty gloves when

performing any maintenance or service to

this tool.

Always remove the battery pack before

performing any service or maintenance on this

tool.

NOTE: It is not necessary to remove the chain or bar

when lubricating the guide bar sprocket.

1. Clean the bar and sprocket

2. Using a grease gun, insert the tip of the gun into

the lubrication hole and inject grease until it

appears at the outside edge of the sprocket tip.

(See Fig. U)

3. To rotate the sprocket pull the chain by hand until

the ungreased side of the sprocket is in line with

the grease hole. Repeat the lubrication procedure.
