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.
GEB118-1
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
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. Always keep proper footing. Slippery or
unstable surfaces may cause a loss of balance or
control of the chain saw.
6. When cutting a limb that is under tension be
alert for spring back. When the tension in the
wood fibers is released the spring loaded limb
may strike the operator and/or throw the 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
off balance.
8. 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.
9. Follow instructions for lubricating, chain
tensioning 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
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.
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
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.

8
014673
−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.
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 fitted
correctly;
• The chain has been sharpened and tensioned
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 specific 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 recommendations
from the relevant professional organization.
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
leakage, damage to the tool and personal injury.
4. Regularly check the functionality of chain brake.
5. Do not fill the chain oil near fire. Never smoke
when you fill 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 firmly 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-fitting 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
regular 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
equipment (ear muffs, 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 recommend 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 fitted with anti skid
sole, steel toe caps and protection for the leg

9
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.
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
fingers, hands or wrists: “Falling asleep”
(numbness), tingling, pain, stabbing sensation,
alteration of skin colour or of the skin. If any of
these symptoms occur, see a physician! To
reduce the risk of “white finger disease”, keep
your hands warm during operation and well
maintain the equipment and accessories.
SAVE THESE INSTRUCTIONS.
WARNING:
DO NOT let comfort or familiarity with product (gained
from repeated use) replace strict adherence to safety
rules for the subject product. MISUSE or failure to
follow the safety rules stated in this instruction manual

Do not cover vents, or it may cause overheating and
damage to the tool.
Lubrication
Fig.18
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 refill the tank, remove the cap from the oil tank
opening.
After refilling the tank, always screw the provided oil
tank cap on the chain saw.
CAUTION:
• When filling the chain saw with chain oil for the
first time, or refilling the tank after it has been
completely emptied, add oil up to the bottom edge
of the filler 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.19
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
CAUTION:
• The first time user should, as a minimum practice,
do cutting logs on a saw-horse or cradle.
• When sawing precut timber use a safe support
(saw horse or cradle). Do not steady the
workpiece with your foot, and do not allow anyone
else to hold or steady it.
• Secure round pieces against rotation.
Pruning trees
Fig.20
CAUTION:
• Keep all parts of the body away from the saw
chain when the motor is operating.
• Hold the chain saw firmly 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.21
When cutting thick branches, first make a shallow
undercut and then make the finish cut from the top.
Fig.22
If you try to cut off thick branches from the bottom, the
branch may close in and pinch the saw chain in the cut.
If you try to cut off thick branches from the top without a
shallow undercut, the branch may splinter.
Fig.23
If you cannot cut the timber right through with a single
stroke:
Apply light pressure to the handle and continue sawing
and draw the chain saw back a little; then apply the
spike a little lower and finish the cut by raising the
handle.
Bucking
Fig.24
For bucking cuts, rest the spike bumper shown in the
figure on the wood to be cut.
With the saw chain running, saw into the wood, using
the top handle to raise the saw and the front one to
guide it. Use the spike bumper as a pivot.
Continue the cut by applying slight pressure to the front
handle, easing the saw back slightly. Move the spike
bumper further down the timber and raise the front
handle again.
When making several cuts, switch the chain saw off
between cuts.
Fig.25
CAUTION:
• If the upper edge of the bar is used for cutting, the
chain saw may be deflected in your direction if the
chain becomes trapped. For this reason, cut with
the lower edge, so that the saw will be deflected
away from your body.
Fig.26
Cut wood under tension on the pressure side (A) first.
Then make the final cut on the tension side (B). This
prevents the bar from becoming trapped.
Limbing
CAUTION:
• Limbing may only be performed by trained
persons. A hazard is presented by the risk of kick-
back.

14
When limbing, support the chain saw on the trunk if
possible. Do not cut with the tip of the bar, as this
presents a risk of kickback.
Pay particular attention to branches under tension. Do
not cut unsupported branches from below.
Do not stand on the felled trunk when limbing.
Burrowing and parallel-to-grain cuts
CAUTION:
• Burrowing and parallel-to-grain cuts may only be
carried out by persons with special training. The
possibility of kickback presents a risk of injury.
Fig.27
Perform parallel-to-grain cuts at as shallow an angle as
possible. Carry out the cut as carefully as possible, as
the spike bumper cannot be used.
Felling
CAUTION:
• Felling work may only be performed by trained
persons. The work is hazardous.
Observe local regulations if you wish to fell a tree.
Fig.28
−Before starting felling work, ensure that:
(1) Only persons involved in the felling operation
are in the vicinity;
(2) Any person involved has an unhindered path
of retreat through a range of approximately
45 ° either side of the felling axis. Consider
the additional risk of tripping over electrical
cables;
(3) The base of the trunk is free of foreign
objects, roots and ranches;
(4) No persons or objects are present over a
distance of 2 1/2 tree lengths in the direction
in which the tree will fall.
−Consider the following with respect to each tree:
• Direction of lean;
• Loose or dry branches;
• Height of the tree;
• Natural overhang;
• Whether or not the tree is rotten.
−Consider the wind speed and direction. Do not
carry out felling work if the wind is gusting strongly.
−Trimming of root swellings: Begin with the largest
swellings. Make the vertical cut first, then the
horizontal cut.
Fig.29
−Cut a scarf: The scarf determines the direction in
which the tree will fall, and guides it. It is made on
the side towards which the tree is to fall. Cut the
scarf as close to the ground as possible. First
make the horizontal cut to a depth of 1/5 -1/3 of
the trunk diameter. Do not make the scarf too
large. Then make the diagonal cut.
−Cut any corrections to the scarf across its entire
width.
Fig.30
−Make the back cut a little higher than the base cut
of the scarf. The back cut must be exactly
horizontal. Leave approximately 1/10 of the trunk
diameter between the back cut and the scarf.
The wood fibers in the uncut trunk portion act as a
hinge. Do not cut right through the fibers under
any circumstances, as the tree will otherwise fall
unchecked. Insert wedges into the back cut in time.
−Only plastic or aluminum wedges may be used to
keep the back cut open. The use of iron wedges is
prohibited.
−Stand to the side of the falling tree. Keep an area
clear to the rear of the falling tree up to an angle of
45 ° either side of the tree axis (refer to the " felling
area " figure). Pay attention to falling branches.
−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.
Fig.31
Carrying tool
Fig.32
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 off and the
battery cartridge is removed before attempting 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.33
Sharpen the saw chain when:
−Mealy sawdust is produced when damp wood is
cut;
−The chain penetrates the wood with difficulty, 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.

15
Sharpen the saw chain frequently, but remove only
a little material each time.
Two or three strokes with a file are usually sufficient 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 differing
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 fitted.
−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.34
WARNING:
• An excessive distance increases the risk of kick-
back.
−The sharpening angle of 30 ° must be the same on
all cutters. Differences 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 file. If the
specified file 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.35
File and file guiding
−Use a special round file (optional accessory) for
saw chains to sharpen the chain. Normal round
files are not suitable.
−Diameter of the round file 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 file should only engage the cutter on the
forward stroke. Lift the file off the cutter on the
return stroke.
−Sharpen the shortest cutter first. Then the length
of this shortest cutter becomes the standard for all
other cutters on the saw chain.
Fig.36
−Guide the file as shown in the figure.
−The file can be guided more easily if a file holder
(optional accessory) is employed. The file 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
file diameter).
Fig.37
−After sharpening the chain, check the height of the
depth gauge using the chain gauge tool (optional
accessory).
Fig.38
−Remove any projecting material, however small,
with a special flat file (optional accessory).
−Round off the front of the depth gauge again.
Cleaning guide bar
Fig.39
Chips and sawdust will build up in the guide bar groove,
clogging it and impairing oil flow. 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
discharge hole during operation.
Small dust or particles built up in the oil discharge hole
may impair the oil discharge flow and cause an
insufficient 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.40
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 flow built-up dust or particles
off 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.41
Before fitting 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 figure.
Fig.42
Always fit a new locking ring when replacing the sprocket.

16
Replacing carbon brushes
Fig.43
Remove and check the carbon brushes regularly.
Replace when they wear down to the limit mark. Keep
the carbon brushes clean and free to slip in the holders.
Both carbon brushes should be replaced at the same
time. Use only identical carbon brushes.
Fig.44
Use a screwdriver to remove the brush holder caps.
Take out the worn carbon brushes, insert the new ones
and secure the brush holder caps.

Splošna varnostna opozorila za
električno orodje
OPOZORILO Preberite vsa varnostna opozorila in
navodila.
Neupoštevanje opozoril in navodil lahko vodi do
električnega udara, požara, in/ali hudih telesnih poškodb.
Shranite vsa opozorila in navodila za
kasnejšo uporabo.
GEB118-1
Varnostna opozorila za uporabo
brezžične verižne žage:
1. Med delovanjem verižne žage ne približujte
delov telesa verigi. Preden zaženete verižno
žago se prepričajte, da se veriga ničesar ne
dotika. Trenutek nepazljivosti pri delu z verižnimi
žagami lahko povzroči zapletanje vaših oblačil ali
telesa v verigo žage.
2. Verižno žago vedno držite z obema rokama, in
sicer z desno roko za zadnji ročaj in z levo za
sprednji ročaj. Obratno držanje verižne žage
poveča tveganje za osebne poškodbe in ga nikoli
ne smete izvesti.
3. Držite električno orodje na izoliranih držalnih
površinah, saj lahko veriga žage prereže
skrito električno napeljavo. Če verige žage
prerežejo vodnike pod napetostjo, dobijo napetost
vsi neizolirani kovinski deli električnega orodja,
zaradi česar lahko uporabnik utrpi električni udar.
4. Uporabljajte zaščitna očala in zaščito za sluh.
Priporočena je dodatna zaščita za glavo, roke,
noge in stopala. Zadostna zaščitna obleka bo
zmanjšala telesne poškodbe zaradi letečih
ostankov ali nenamernega stika z verigo žage.
5. Vedno uporabljajte ustrezno obutev. Drseča ali
nestabilna površina lahko povzroči izgubo
ravnotežja ali nadzora nad verižno žago.
6. Kadar režete napeto vejo, bodite pozorni, ko
odskoči nazaj. Ko se napetost lesnih vlaken
sprosti, lahko veja udari upravljavca in/ali
povzroči nenadzorovano premikanje verižne žage.
7. Bodite izjemno previdni pri rezanju mladik in
sadik. Vitek material lahko ujame verigo žage in
jo vrže proti vam ali povzroči izgubo ravnotežja.
8. Verižno žago nosite tako, da jo izklopljeno
držite za sprednji ročaj in obrnjeno stran od
telesa. Kadar nosite ali shranjujete verižno
žago, vedno namestite pokrivalo meča.
Ustrezno ravnanje z verižno žago bo zmanjšalo
verjetnost nenamernega stika s premikajočo se
verigo.
9. Upoštevajte navodila glede mazanja,
napetosti verige in menjave pripomočkov.
Nepravilno napeta ali namazana veriga se lahko
strga ali poveča možnost povratnega udarca.
10. Ročaji morajo biti suhi, čisti in brez olja ter
masti. Mastni, naoljeni ročaji so drseči in
povzročijo izgubo nadzora.
11. Režite samo les. Verižne žage ne uporabljajte
v nepredvidene namene. Na primer: verižne
žage ne uporabljajte za rezanje plastike, zidov
ali nelesenih gradbenih elementov. Uporaba
verižne žage, ki ni v skladu z namensko uporabo,
lahko povzroči nevarno situacijo.
12. Vzroki in preprečevanje povratnega udarca s
strani upravljavca:
Povratni udarec se lahko pojavi, če se konica
meča dotakne kakšnega predmeta ali ko se les
zapre in uklešči verigo v reži.
Stik konice lahko v nekaterih primerih povzroči
nenadno obratno reakcijo, ki vrže mečnavzgor in
nazaj proti upravljavcu.
Zagozditev verige žage na vrhu meča lahko hitro
potisne mečnazaj proti upravljavcu.
Katera koli izmed teh reakcij lahko povzroči izgubo
nadzora nad žago, kar lahko povzroči hude
telesne poškodbe. Ne zanašajte se izključno na
zaščitne naprave, vgrajene v vašo žago. Kot
uporabnik verižne žage morate izvesti nekaj
korakov, da preprečite nesreče ali poškodbe med
delom.
Povratni udarec je posledica nestrokovnega
ravnanja z orodjem in/ali neugodnih okoliščin.
Preprečite ga lahko z upoštevanjem spodaj
navedenih opozoril.
−Trdno držite žago, tako da s sklenjenimi
prsti držite ročaja, imate obe roki na žagi
in namestite telo ter roki tako, da boste
lahko prestregli sile povratnega udarca.
Sile povratnega udarca lahko upravljavec
nadzoruje, če izvede pravilne previdnostne
ukrepe. Ne izpustite verižne žage.
