SAFETY WARNINGS
General power tool safety warnings
WARNING: Read all safety warnings, instruc-
tions, illustrations and specications provided
with this power tool. Failure to follow all instructions
listedbelowmayresultinelectricshock,reand/or
serious injury.
Save all warnings and instruc-
tions 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
1. Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
2. Do not operate power tools in explosive atmo-
spheres, such as in the presence of ammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
3. Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
Electrical safety
1. 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. Unmodiedplugsandmatchingoutletswill
reduce risk of electric shock.
2. Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of elec-
tric shock if your body is earthed or grounded.
3. Do not expose power tools to rain or wet con-
ditions. Water entering a power tool will increase
the risk of electric shock.
4. 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.
5. 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.
6. 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.
7.
Power tools can produce electromagnetic elds
(EMF) that are not harmful to the user. However,
users of pacemakers and other similar medical
devices should contact the maker of their device and/
or doctor for advice before operating this power tool.
Personal safety
1. 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 inuence of drugs, alcohol or med-
ication. A moment of inattention while operating
power tools may result in serious personal injury.
2. 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.
3. Prevent unintentional starting. Ensure the
switch is in the o󰀨-position before connecting
to power source and/or battery pack, picking
up or carrying the tool. Carrying power tools with
yourngerontheswitchorenergisingpowertools
that have the switch on invites accidents.
4. 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.
5. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
6. 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.
7. 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.

4ENGLISH
8. 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.
9. Always wear protective goggles to protect
your eyes from injury when using power tools.
The goggles must comply with ANSI Z87.1 in
the USA, EN 166 in Europe, or AS/NZS 1336
in Australia/New Zealand. In Australia/New
Zealand, it is legally required to wear a face
shield to protect your face, too.
It is an employer's responsibility to enforce
the use of appropriate safety protective equip-
ments by the tool operators and by other per-
sons in the immediate working area.
Power tool use and care
1. 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.
2. Do not use the power tool if the switch does
not turn it on and o󰀨. Any power tool that cannot
be controlled with the switch is dangerous and
must be repaired.
3. Disconnect the plug from the power source
and/or remove the battery pack, if detachable,
from the power tool before making any adjust-
ments, changing accessories, or storing power
tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
4. Store idle power tools out of the reach of chil-
dren 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.
5.
Maintain power tools and accessories. Check for
misalignment or binding of moving parts, break-
age of parts and any other condition that may
a󰀨ect the power tool’s operation. If damaged, have
the power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
6. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
7. Use the power tool, accessories and tool bits
etc. in accordance with these instructions, tak-
ing into account the working conditions and
the work to be performed. Use of the power tool
foroperationsdi󰀨erentfromthoseintendedcould
result in a hazardous situation.
8.
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.
9. When using the tool, do not wear cloth work
gloves which may be entangled. The entangle-
ment of cloth work gloves in the moving parts may
result in personal injury.
Battery tool use and care
1. Recharge only with the charger specied by
the manufacturer. A charger that is suitable for
onetypeofbatterypackmaycreateariskofre
when used with another battery pack.
2. Use power tools only with specically desig-
nated battery packs. Use of any other battery
packsmaycreateariskofinjuryandre.
3. 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 termi-
nalstogethermaycauseburnsorare.
4.
Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact acci-
dentally occurs, ush with water. If liquid con-
tacts eyes, additionally seek medical help. Liquid
ejected from the battery may cause irritation or burns.
5. Do not use a battery pack or tool that is dam-
aged or modied.Damagedormodiedbatteries
may exhibit unpredictable behaviour resulting in
re,explosionorriskofinjury.
6. Do not expose a battery pack or tool to re or
excessive temperature.Exposuretoreortem-
perature above 130 °C may cause explosion.
7. Follow all charging instructions and do not
charge the battery pack or tool outside the
temperature range specied in the instruc-
tions. Charging improperly or at temperatures
outsidethespeciedrangemaydamagethe
batteryandincreasetheriskofre.
Service
1. Have your power tool serviced by a qualied
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
2. Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
3. Follow instruction for lubricating and chang-
ing accessories.
Cordless 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congurationincreasestheriskof
personal injury and should never be done.

5ENGLISH
3.
Hold the chain saw by insulated gripping sur-
faces only, because the saw chain may contact
hidden wiring. Saw chains contacting a "live" wire
may make exposed metal parts of the chain saw
"live" and could give the operator an electric shock.
4. Wear eye protection. Further protective equip-
ment for hearing, head, hands, legs and feet is
recommended. Adequate protective equipment
willreducepersonalinjuryfromyingdebrisor
accidental contact with the saw chain.
5. Do not operate a chain saw in a tree, on a lad-
der, from a rooftop, or any unstable support.
Operation of a chain saw in this manner could
result in serious personal injury.
6. Always keep proper footing and operate the
chain saw only when standing on xed, secure
and level surface. Slippery or unstable surfaces
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bres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 sap-
lings. The slender material may catch the saw chain
andbewhippedtowardyouorpullyouo󰀨balance.
9. Carry the chain saw by the front handle with
the chain saw switched o󰀨 and away from your
body. When transporting or storing the chain
saw, always t 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 the bar and chain.
Improperly tensioned or lubricated chain may
either break or increase the chance for kickback.
11. Cut wood only. Do not use chain saw for pur-
poses not intended. For example: do not use
chain saw for cutting metal, plastic, masonry
or non-wood building materials. Use of the
chainsawforoperationsdi󰀨erentthanintended
could result in a hazardous situation.
12. This chain saw is not intended for tree felling.
Useofthechainsawforoperationsdi󰀨erentthan
intended could result in serious injury to the opera-
tor or bystanders.
13. 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 chain saw misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below:
• Maintain a rm grip, with thumbs and
ngers 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 precau-
tions are taken. Do not let go of the chain
saw.
• Do not overreach and do not cut above
shoulder height. This helps prevent unin-
tended tip contact and enables better control
of the chain saw in unexpected situations.
• Only use replacement guide bars and saw
chains specied by the manufacturer.
Incorrect replacement guide bars and saw
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.
14. Follow all instructions when clearing jammed
material, storing or servicing the chain saw.
Make sure the switch is o󰀨 and the battery
pack is removed. Unexpected actuation of the
chain saw while clearing jammed material or
servicing may result in serious personal injury.
ADDITIONAL SAFETY RULES
1. Before starting work, check that the chain
saw is in proper working order and that its
condition complies with the safety regulations.
Check in particular that:
• Thebarandthesprocketcoveraretted
correctly;
• The chain has been sharpened and ten-
sioned in accordance with the regulations.
2. Do not start the chain saw with the chain cover
being installed on it. Starting the chain saw with
the chain cover being installed on it may cause
the chain cover to thrown out forward resulting in
personal injury and damage to objects around the
operator.
3. Avoid dangerous environment. Don't use the
tool in damp or wet locations or expose it to
rain. Water entering the tool will increase the
risk of electric shock.
4. Do not dispose of the battery(ies) in a re. The

through the oil inspection window.
Torellthetank,removethecapfromtheoiltank
opening.
Afterrellingthetank,alwaysscrewtheprovidedoil
tank cap on the chain saw.
CAUTION:
• Do not operate the chain saw when the tank is
empty. Replenish the oil in due time before the
tank is empty.
• Whenllingthechainsawwithchainoilforthe
rsttime,orrellingthetankafterithasbeen
completely emptied, add oil up to the bottom
edgeofthellerneck.Theoildeliverymay
otherwise be impaired.
• As a saw chain oil, use oil exclusively for Makita
chain saws or oil available in market.
• Never use oil including dust and particles or
volatile oil.
• When pruning trees, use botanical oil. Mineral
oil may harm trees.
• Never force the chain saw when pruning trees.
• Before cutting out, make sure that the provided
oil tank cap is screwed in place.
Hold the chain saw away from the tree. Start it and wait
until lubrication on saw chain is adequate.
Bring the tip guide/lower guide into contact with the
branch to be cut before switching on. Cutting without
bringing the tip guide/lower guide into contact with the
branch may cause the guide bar to wobble, resulting in
injury to operator.
Saw the wood to be cut by just moving it down.

►1. Battery cartridge 2. Scabbard (chain cover)
Always remove the battery cartridge from the tool and
overlap the guide bar with the scabbard before carrying
the tool. Also cover the battery cartridge with the battery
cover.
MAINTENANCE
CAUTION:
• Alwaysbesurethatthetoolisswitchedo󰀨and
the battery cartridge is removed before attempt-
ing to perform inspection or maintenance.
• Always wear gloves when performing any
inspection or maintenance.
• Never use gasoline, benzine, thinner, alcohol
or the like. Discoloration, deformation or cracks
may result.
Sharpening the saw chain
CAUTION:
• Always remove the battery cartridge and wear
safety gloves when performing work on the saw
chain.
Sharpen the saw chain when:
— Mealy sawdust is produced when damp wood is cut;
— Thechainpenetratesthewoodwithdi󰀩culty,even
when heavy pressure is applied;
— The cutting edge is obviously damaged;
— The saw pulls to the left or right in the wood. The
reason for this behaviour is uneven sharpening of
the saw chain, or damage to one side only.
Sharpen the saw chain frequently, but
remove only a little material each time.
Twoorthreestrokeswithaleareusuallysu󰀩cientforroutine
resharpening. When the saw chain has been resharpened sev-
eral times, have it sharpened in a MAKITA specialist repair shop.
File and le guiding
— Useaspecialroundle(optionalaccessory)for
saw chains, with a diameter of 4 mm, to sharpen
thechain.Normalroundlesarenotsuitable.
— Theleshouldonlyengagethematerialontheforward
stroke.Lifttheleo󰀨thematerialonthereturnstroke.

ings for the correct sharpening angle of 30 ° (align
the markings parallel to the saw chain) and limits the
depthofpenetration(to4/5ofthelediameter).
