General Power Tool Safety Warnings
WARNING Read all safety warnings and all
instructions. Failure to follow the warnings and instruc-
tions 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
4. 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.
5. 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.
6. Do not expose power tools to rain or wet con-
ditions. Water entering a power tool will increase
the risk of electric shock.
7. 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.
8. 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.
9. If operating a power tool in a damp location is
unavoidable, use a ground fault circuit inter-
rupter (GFCI) protected supply. Use of an GFCI
reduces the risk of electric shock.
Personal safety
10. 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.
11. 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.
12. 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.
13. 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.
14. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
15. Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing, and gloves
away from moving parts. Loose clothes, jewel-
lery or long hair can be caught in moving parts.
16. 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.
Power tool use and care
17. 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.
18. 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.
19. 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 pre-
ventive safety measures reduce the risk of starting
the power tool accidentally.

9ENGLISH
20. 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.
21. Maintain power tools. Check for misalignment
or binding of moving parts, breakage 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.
22. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
23. 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.
Battery tool use and care
24. 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.
25. 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.
26. 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.
27. Under abusive conditions, liquid may be
ejected from the battery; avoid contact. If con-
tact accidentally occurs, ush with water. If
liquid contacts eyes, additionally seek medical
help. Liquid ejected from the battery may cause
irritation or burns.
Service
28. 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.
29. Follow instruction for lubricating and chang-
ing accessories.
30. Keep handles dry, clean and free from oil and
grease.
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. When holding with both hands, 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.
3. Hold the power tool by insulated gripping
surfaces only, because the saw chain may con-
tact 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 pro-
tective clothing will reduce personal injury by ying
debris or accidental contact with the saw chain.
5. Always keep proper footing. Slippery or unsta-
ble surfaces may cause a loss of balance or con-
trol of the chain saw.
6. When cutting a limb that is under tension be
alert for spring back. When the tension in the
wood bers is released the spring loaded limb may
strike the operator and/or throw the chain saw out
of control.
7. Use extreme caution when cutting brush and
saplings. The slender material may catch the saw
chain and be whipped toward you or pull you o󰀨
balance.
8. 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.
9. Follow instructions for lubricating, chain ten-
sioning and changing accessories. Improperly
tensioned or lubricated chain may either break or
increase the chance for kickback.
10. Keep handles dry, clean, and free from oil and
grease. Greasy, oily handles are slippery causing
loss of control.
11. Cut wood only. Do not use chain saw for pur-
poses 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 di󰀨erent than intended could result
in a hazardous situation.
12. 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 incor-
rect operating procedures or conditions and can
be avoided by taking proper precautions as given
below:

10 ENGLISH
— 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.
► Fig.1
— 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 bars and chains
specied 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.
13. 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 chain brake is working properly;
• The run-down brake is working properly;
• The bar and the sprocket cover are tted
correctly;
• The chain has been sharpened and ten-
sioned in accordance with the regulations;
14.
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.
Top handle chainsaw specic safety
warnings
1. This chain saw is designed especially for tree
care and surgery. The chain saw is intended to be
used by properly trained persons only. Observe
all instructions, procedures and recommenda-
tions from the relevant professional organiza-
tion. Otherwise fatal accidents may occur. It is
recommend that always using a rising platform
(cherry picker, lift) for sawing in trees. Rappelling
techniques are extremely dangerous and require
special training. The operators must be trained to
become familiar with safety equipment usage and
climbing techniques. Always use the appropriate
belts, ropes and carabiners when working in trees.
Always use restraining equipment for both the
operator and the saw.
2. Perform cleaning and maintenance before storage
in accordance with the instruction manual.
3. Ensure safe positioning of the chain saw during
car transportation to avoid fuel or chain oil leak-
age, damage to the tool and personal injury.
4. Regularly check the functionality of chain brake.
5. Do not ll the chain oil near re. Never smoke
when you ll the chain oil.
6. National regulation may restrict the use of the
chain saw.
7. If the equipment gets heavy impact or fall, check
the condition before continuing work. Check the
controls and safety devices for malfunction. If
there is any damage or doubt, ask our authorized
service center for the inspection and repair.
8. Always activate the chain brake before starting the
chain saw.
9. Hold the saw rmly in place to avoid skating (skid
movement) or bouncing of the saw when starting a
cut.
10. At the end of the cut, be careful to keep your
balance due to the “drop”.
11. Take into account the direction and speed of the
wind. Avoid sawdust and chain oil mist.
Protective equipment
1. In order to avoid head, eye, hand or foot
injuries as well as to protect your hearing the
following protective equipment must be used
during operation of the chain saw:
— The kind of clothing should be appropriate,
i. e. it should be tight-tting but not be a
hindrance. Do not wear jewelry or clothing
which could become entangled with bushes
or shrubs. If you have long hair, always wear
a hairnet!
— It is necessary to wear a protective helmet
whenever working with the chain saw. The
protective helmet is to be checked in regu-
lar intervals for damage and is to be replaced
after 5 years at the latest. Use only approved
protective helmets.
— The face shield of the protective helmet (or
the goggles) protects against sawdust and
wood chips. During operation of the chain
saw always wear a goggle or a face shield to
prevent eye injuries.
— Wear adequate noise protection equip-
ment (ear mu󰀨s, ear plugs, etc.).
— The protective jacket consists of 22 layers
of nylon and protects the operator against
cuts. It is always to be worn when working
from elevated platforms (cherry pickers,
lifts), from platforms mounted on ladders or
when climbing with ropes.
— The protective brace and bib overall is
made of a nylon fabric with 22 layers and
protects against cuts. We strongly recom-
mend its use.
— Protective gloves made of thick leather are
part of the prescribed equipment and must
always be worn during operation of the chain
saw.
— During operation of the chain saw safety
shoes or safety boots tted with anti skid
sole, steel toe caps and protection for the
leg must always to be worn. Safety shoes
equipped with a protective layer provide
protection against cuts and ensure a secure
footing. For working in trees the safety boots
must be suitable for climbing techniques.

11 ENGLISH
Vibration
1. Individuals with poor circulation who are exposed
to excessive vibration may experience injury to
blood vessels or the nervous system. Vibration
may cause the following symptoms to occur in the
ngers, hands or wrists: “Falling asleep” (numb-
ness), tingling, pain, stabbing sensation, alteration
of skin colour or of the skin. If any of these symp-
toms occur, see a physician! To reduce the risk
of “white nger disease”, keep your hands warm
during operation and well maintain the equipment
and accessories.

CAUTION: Do not cover vents, or it may cause
overheating and damage to the tool.
Lubrication
► Fig.20: 1. Oil tank cap 2. Oil inspection window ( for rell-
ing the tank with oil) 3. Oil inspection window
Saw chain is automatically lubricated when the tool is
in operation.
Check the amount of remaining oil in the oil tank
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:
• 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.
► Fig.21
Hold the chain saw away from the tree. Start it and wait
until lubrication on saw chain is adequate.
Bring the spike bumper into contact with the branch to
be cut before switching on. Otherwise it may cause the
guide bar to wobble, resulting in injury to operator.
Saw the wood to be cut by just moving it down.
WORKING WITH THE CHAIN SAW
Pruning trees
► Fig.22: 1. Spike bumper
CAUTION:
• Keep all parts of the body away from the saw
chain when the motor is operating.
• Hold the chain saw rmly with both hands when
the motor is running.
• Do not overreach. Keep proper footing and
balance at all times.
Bring the spike bumper into contact with the branch to
be cut before switching on. Cutting without bringing the
spike bumper into contact with the branch may cause
the guide bar to wobble, resulting in injury to operator.
► Fig.23
When cutting thick branches, rst make a shallow
undercut and then make the nish cut from the top.
► Fig.24
If you try to cut o󰀨 thick branches from the bottom, the
branch may close in and pinch the saw chain in the cut.
If you try to cut o󰀨 thick branches from the top without a
shallow undercut, the branch may splinter.
► Fig.25
If you cannot cut the timber right through with a single
stroke:
Apply light pressure to the handle and continue saw-
ing and draw the chain saw back a little; then apply
the spike a little lower and nish the cut by raising the
handle.
Carrying tool
► Fig.26: 1. Guide bar cover 2. Battery cover
Always remove the battery cartridge from the tool and
overlap the guide bar with the guide bar cover 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.
► Fig.27

16 ENGLISH
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 several times, have it sharpened in a
MAKITA specialist repair shop.
Sharpening criteria:
— All cutter length must be equal. Cutters of di󰀨ering
length prevent the chain from running smoothly,
and may cause the chain to break.
— Do not sharpen the chain once a minimum cutter
length of 3 mm has been reached. A new chain
must then be tted.
— The chip thickness is determined by the distance
between the depth gauge (round nose) and the
cutting edge.
— The best cutting results are obtained with following
distance between cutting edge and depth gauge.
Chain blade 90PX: 0.5 mm
Chain blade 91PX: 0.65 mm
Chain blade 25AP: 0.65 mm
► Fig.28: 1. Cutting length 2. Distance between
cutting edge and depth gauge 3. Minimum
3 mm
WARNING:
• An excessive distance increases the risk of
kick-back.
— The sharpening angle of 30 ° must be the same
on all cutters. Di󰀨erences in angle cause the chain
to run roughly and unevenly, accelerate wear, and
lead to chain breaks.
— The side plate angle of the cutter is determined
by the depth of penetration of the round le. If the
specied le is used properly, the correct side
plate angle is produced automatically.
— Side plate angle for each saw chain are as follows:
Chain blade 90PX: 75 °
Chain blade 91PX: 80 °
Chain blade 25AP: 85 °
► Fig.29: 1. Side plate angle
File and le guiding
— Use a special round le (optional accessory) for
saw chains to sharpen the chain. Normal round
les are not suitable.
— Diameter of the round le for each saw chain is as
follows:
Chain blade 90PX: 4.5 mm
Chain blade 91PX: 4.0 mm
Chain blade 25AP: 4.0 mm
—
The le should only engage the cutter on the forward
stroke. Lift the le o󰀨 the cutter on the return stroke.
— Sharpen the shortest cutter rst. Then the length
of this shortest cutter becomes the standard for all
other cutters on the saw chain.
► Fig.30
— Guide the le as shown in the gure.
—
The le can be guided more easily if a le holder
(optional accessory) is employed. The le holder has
markings 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).
► Fig.31
— After sharpening the chain, check the height of the
depth gauge using the chain gauge tool (optional
accessory).
► Fig.32
— Remove any projecting material, however small,
with a special at le (optional accessory).
— Round o󰀨 the front of the depth gauge again.
Cleaning guide bar
► Fig.33
Chips and sawdust will build up in the guide bar groove,
clogging it and impairing oil ow. Always clean out the chips
and sawdust when sharpening or replacing the saw chain.
Cleaning the oil discharge hole
Small dust or particles may be built up in the oil dis-
charge hole during operation.
Small dust or particles built up in the oil discharge hole
may impair the oil discharge ow and cause an insu󰀩-
cient lubrication on the whole saw chain.
When a poor chain oil delivery occurs at the top of
guide bar, clean the oil discharge hole as follows.
Remove the battery cartridge from the tool.
Remove the sprocket cover and saw chain from the
tool. (Refer to the section titled " Installing or removing
saw chain ".)
► Fig.34: 1. Slotted screwdriver
Remove the small dust or particles using a slotted
screwdriver with a slender shaft or the like.
Insert the battery cartridge into the tool.
Pull the switch trigger to ow built-up dust or particles
o󰀨 the oil discharge hole by discharging chain oil.
Remove the battery cartridge from the tool.
Reinstall the sprocket cover and saw chain on the tool.
Replacing the sprocket
► Fig.35: 1. Sprocket 2. Locking ring
Before tting a new saw chain, check the condition of
the sprocket.
CAUTION:
• A worn sprocket will damage a new saw chain.
Have the sprocket replaced in this case. The
sprocket needs to be installed so that it always
faces as shown in the gure.

Общие рекомендации по
технике безопасности для
электроинструментов
ПРЕДУПРЕЖДЕНИЕ Ознакомьтесь со всеми
инструкциями и рекомендациями по технике без-
опасности. Невыполнение инструкций и рекомен-
даций может привести к поражению электротоком,
пожару и/или тяжелым травмам.
Сохраните брошюру с инструк-
циями и рекомендациями для
дальнейшего использования.
Термин "электроинструмент" в предупреждениях
относится ко всему инструменту, работающему от
сети или на аккумуляторах.
Безопасность в месте выполнения работ
1. Рабочее место должно быть чистым и
хорошо освещенным. Захламление и плохое
освещение могут стать причиной несчастных
случаев.
2. Не пользуйтесь электроинструментом во
взрывоопасной атмосфере, например в
присутствии легко воспламеняющихся жид-
костей, газов или пыли. При работе электро-
инструмента возникают искры, которые могут
привести к воспламенению пыли или газов.
3. При работе с электроинструментом не
допускайте детей или посторонних к месту
выполнения работ. Не отвлекайтесь во время
работы, так как это приведет к потере контроля
над электроинструментом.
Электробезопасность
4. Вилка электроинструмента должна соот-
ветствовать сетевой розетке. Никогда не
вносите никаких изменений в конструкцию
розетки. При использовании электроинстру-
мента с заземлением не используйте пере-
ходники. Розетки и вилки, не подвергавшиеся
изменениям, снижают риск поражения электри-
ческим током.
5. Избегайте контакта участков тела с зазем-
ленными поверхностями, такими как трубы,
радиаторы, батареи отопления и холо-
дильники. При контакте тела с заземленными
предметами увеличивается риск поражения
электрическим током.
6. Не подвергайте электроинструмент воздей-
ствию дождя или влаги. Попадание воды в
электроинструмент повышает риск поражения
электрическим током.
7. Аккуратно обращайтесь со шнуром питания.
Никогда не используйте шнур питания для
переноски, перемещения или извлечения
вилки из розетки. Располагайте шнур на
расстоянии от источников тепла, масла,
острых краев и движущихся деталей.
Поврежденные или запутанные сетевые шнуры
увеличивают риск поражения электрическим
током.
8. При использовании электроинструмента
вне помещения используйте удлинитель,
подходящий для этих целей. Использование
соответствующего шнура снижает риск пораже-
ния электрическим током.
9. Если электроинструмент приходится экс-
плуатировать в сыром месте, используйте
линию электропитания, которая защищена
прерывателем, срабатывающим при замы-
кании на землю (GFCI). Использование GFCI
снижает риск поражения электротоком.
Личная безопасность
10. При использовании электроинструмента
будьте бдительны, следите за тем, что
вы делаете, и руководствуйтесь здравым
смыслом. Не пользуйтесь электроинстру-
ментом, если вы устали, находитесь под
воздействием наркотиков, алкоголя или
лекарственных препаратов. Даже мгновен-
ная невнимательность при использовании
электроинструмента может привести к серьез-
ной травме.
