children, young people, and persons under the inuence of
drugs, alcohol or medication must not use this saw.
National regulations may restrict the use of the unit!
General precautions
- To ensure correct operation the user has to read
this instruction manual to make himself familiar with
the charac teristics of the chain saw. Users insufciently
informed will endanger themselves as well as others due to
improper handling.
- It is recommended to lend the chain saw only to people who
are experienced in working with chain saws. Always hand
over the instruction manual.
- First users should ask the dealer for basic instructions
to become familiarized with the characteristics of engine
powered sawing or even attend a recognized course of
instruction.
- Children and young persons aged under 18 years must
not be allowed to operate the chain saw. Persons over the
age of 16 years may, however, use the chain saw for the
purpose of being trained as long as they are under the
supervision of a qualied trainer.
- Use chain saws always with the utmost care and attention.
- Operate the chain saw only if you are in good physical
condition. If you are tired, your attention will be reduced. Be
especially careful at the end of a working day. Perform all
work calmly and carefully. The user has to accept liability for
others.
- Never use the chain saw after having consumed alcohol,
drugs or medication.
‑ A re extinguisher must be available in the immediate
vicinity when working in easily inammable vegetation or
when it has not rained for a long time (danger of re).
Protective equipment
- 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 jewellery 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 (1)
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 (2) 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
(3), ear plugs, etc.). Octave brand analysis upon request.
- The safety jacket (4) is provided with special
signal-coloured shoulder straps and is comfortable and easy
to care for.
- The protective brace and bib overall (5) is made of a nylon
fabric with multiple layers and protects against cuts. We
strongly recommend its use.
- Protective gloves (6) 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 (7) tted with anti skid sole, steel toe
caps and protection for the leg must always to be worn.

Fuels / Refuelling
- Stop the engine before refuelling the chain saw.
‑ Do not smoke or work near open res (5).
- Let the engine cool down before refuelling.
- Fuels can contain substances similar to solvents. Eyes and
skin should not come in contact with mineral oil products.
Always wear protective gloves when refuelling. Frequently
clean and change protective clothes. Do not breathe in fuel
vapors. Inhalation of fuel vapours can be hazardous to your
health.
- Do not spill fuel or chain oil. When you have spilt fuel or oil
immediately clean the chain saw. Fuel should not come in
contact with clothes. If your clothes have come in contact with
fuel, change them ot once.
- Ensure that no fuel or chain oil oozes into the soil
(environmental protection). Use an appropriate base.
- Refuelling is not allowed in closed rooms. Fuel vapors will
accumulate near the oor (explosion hazard).
‑ Ensure to rmly tighten the screw plugs of the fuel and oil
tanks.
- Change the place before starting the engine (at least 3 m from
the place of refuelling) (6).
- Fuel cannot be stored for an unlimited period of time. Buy only
as much as will be consumed in the near future.
- Use only approved and marked containers for the transport
and storage of fuel and chain oil. Ensure children have no
access to fuel or chain oil.
Putting into operation
- Do not work on your own. Another person must be nearby
in case of emergencies (within shouting distance).
- Ensure that there are no children or other people within the
working area. Pay attention to any animals in the working
area, as well (7).
- Before starting work the chain saw must be checked for
perfect function and operating safety according to the
prescriptions.
Check especially the function of the chain brake, the correct
mounting of the guide bar, the correct sharpening and
tightening of the chain, the rm mounting of the sprocket
guard, the easy motion of the throttle lever and the function
of the throttle lever lock, the cleanliness and dryness of the
handles, and the function of the ON/OFF switch.
- Put the chain saw only into operation if it is completely
assembled. Never use the chain saw when it is not completely
assembled.
- Before starting the chain saw ensure that you have a safe footing.
- Put the chain saw into operation only as described in this
instruction manual (8). Other starting methods are not
allowed.
- When starting the chain saw it must be well supported and
securely held. The guide bar and chain must not be in contact
with any object.
- When working with the chain saw always hold it with
both hands. Take the back handle with the right hand and the
tubular handle with the left hand. Hold the handles tightly with
your thumbs facing your ngers.
- CAUTION: When releasing the throttle lever the chain will
keep on running for a short period of time (free-wheeling).
- Continuously ensure that you have a safe footing.
- Hold the chain saw such that you will not breathe in the
exhaust gas. Do not work in closed rooms (danger of
poisoning).
- Switch off the chain saw immediately if you observe any
changes in its operating behavior.
- The engine must be switched off before checking the
chain tension, tightening the chain, replacing it or
clearing malfunctions (9).
- When the sawing device is hit by stones, nails or other hard
objects, switch off the engine immediately and check the
sawing device. If the chain saw is exposed to force, such
as through impact or falling, inspect the entire chain saw for
proper functioning.
- When stopping work or leaving the working place switch off the
chain saw (9) and put it down such that nobody is endangered.
CAUTION:Do not put the overheated power
chain saw in dry grass or on any inammable
objects. The mufer is very hot (danger of re).
- CAUTION: Oil dropping from the chain or guide bar after
having stopped the saw chain will pollute the soil. Always use
an appropriate base.

Kickback
- When working with the chain saw dangerous kickbacks may
occur.
- Kickback occurs when the upper part of the end of the guide
bar inadvertently touches wood or other hard objects (10).
- This causes the saw to be thrown back toward the user with
great force and out of control. Risk of injury!
In order to prevent kickback, follow these rules:
- Only specially-trained persons should perform plunge cuts,
i.e., piercing timber or wood with the tip of the saw!
- Never apply the end of the bar when starting to make a cut.
- Always observe the end of the guide bar. Be careful when
continuing an already started cut.
- When starting to cut the chain must be running.
- Ensure that the chain is always sharpened correctly. Pay
special attention to the height of the depth limiter.
- Never cut several branches at the same time. When cutting a
branch ensure that no other branch is touched.
- When crosscutting a trunk be aware of the trunks next to it.
Working behavior/Method of working
- Only use the chain saw during good light and visibility
periods. Be aware of slippery or wet areas, and of ice and
snow (risk of slipping). The risk of slipping is extremely high
when working on recently peeled wood (bark).
- Never work on unstable surfaces. Make sure that there are
no obstacles in the working area, risk of stumbling. Always
ensure that you have a safe footing.
- Never saw above your shoulder height (11).
- Never saw while standing on a ladder (11).
- Never climb up into trees to perform sawing with the chain
saw.
- Do not work leaning too far over.
- Guide the chain saw in such a way that no part of your body
is within the elongated swivelling range of the saw (12).
- Use the chain saw for sawing wood only.
- Avoid touching the ground with the chain saw while it is still
running.
- Never use the chain saw for lifting up or removing pieces of
wood or other objects.
- Remove foreign objects such as sand, stones and nails
found within the working area. Foreign objects may damage
the sawing device and can cause dangerous kickback.
- When sawing precut timber use a safe support (sawing jack,
13). Do not steady the workpiece with your foot, and do not
allow anyone else to hold or steady it.
- Secure round pieces against rotation.
-For cutting down trees or performing crosscuts the
spike bar (13, Z) must be applied to the wood to be cut.
- Before performing a crosscut rmly apply the spike bar to
the timber, only then can the timber be cut with the chain
running. For this the chain saw is lifted at the back handle
and guided with the tubular handle. The spike bar serves as
a centre of rotation. Continue by slightly pressing down the
tubular handle and simultaneously pulling back the chain
saw. Apply the spike bar a little bit deeper and once again lift
the back handle.
- When the timber must be pierced for cutting or
longitudinal cuts are to be performed it is urgently
recommended to have this carried out by specially
trained persons only (high risk of kickback).
- When starting a cut, the blade can slip to the side or jump
slightly. This depends on the wood and the condition of the
chain. Therefore, always hold the chain saw with both
hands.
- Do longitudinal - lengthwise - cuts at the lowest possible
angle (14). Be very careful when doing this type of cut, as
the spike bar cannot grip.
- The saw must be running whenever you remove the chain
saw from the wood.
- When performing several cuts the throttle lever must be
released in between.

= cutting down area
- Be careful when cutting splintery wood. Cut pieces of wood
may be pulled along (risk of injuries).
- When cutting with the upper edge of the guide bar, the chain
saw may be pushed in the direction of the user if the chain
gets clamped. For this reason use the lower edge of the bar
whenever possible. The chain saw will then be pushed away
from you (15).
‑ If the timber is under tension (16), rst cut the pressure side
(A). Then the crosscut can be performed on the tension side
(B). Thus clamping of the guide bar can be avoided.
- At the end of the cut the weight of the chain saw will cause it
to swing through, since it is no longer held by the cut. Hold it
rmly to control this.
CAUTION:
People felling trees or cutting of branches must be
specially trained. High risk of injuries!
- When cutting of branches, the chain saw should be
supported on the trunk. Do not use the end of the bar for
cutting (risk of kickback).
- Be aware of branches under tension. Do not cut free
branches from below.
- Never perform detensioning cuts while standing on the trunk.
- Before cutting down a tree ensure that
a) only those people are within the working area which are
actually involved in cutting down the tree.
b) every worker involved can withdraw without stumbling
(the people should withdraw backwards in a diagonal
line, i. e. at a degree of 45°).
c) the bottom part of the trunk is free from foreign objects,
underbrush and branches. Make sure to have a safe
footing (risk of stumbling).
d) the next working place is at least 2 1/2 tree lengths away
(17). Before cutting down the tree check the direction
of fall and make sure that there are neither people nor
objects within a distance of 2 1/2 tree lengths.
- Judging the tree:
Direction of hanging - loose or dry branches - height of the
tree - natural overhang - is the tree rotten?
- Take into account the direction and speed of the wind. If
strong gusts are occurring, do not do any felling.
- Cutting the roots:
Start with the strongest root. First do the vertical and then the
horizontal cut.
- Notching the trunk (18, A):
The notch determines the direction of fall and guides the
tree. The trunk is notched perpendicular to the direction of
fall and penetrates 1/3 -1/5 of the trunk diameter. Perform the
cut near the ground.
- When correcting the cut, always do so over the whole width
of the notch.
- Cut down the tree (19, B) above the bottom edge of the
notch (D). The cut must be exactly horizontal. The distance
between both cuts must be approx. 1/10 of the trunk
diameter.
- The material between both cuts (C) serves as a hinge.
Never cut it through, otherwise the tree will fall without any
control. Insert felling wedges in time.
- Secure the cut only with wedges made of plastic or
aluminium. Do not use iron wedges. If the saw hits an iron
wedge the chain can be seriously damaged or torn.
- When cutting down a tree always stay sidewards of the
falling tree.
- When withdrawing after having performed the cut, be alert
for falling branches.
- When working on sloping ground the user of the chain saw
must stay above or sidewards of the trunk to be cut or the
tree already cut down.
- Be alert for trunks which may roll towards you.

SERVICE
Transport and storage
- When changing your location during work switch off
the chain saw and actuate the chain brake in order to
prevent an inadvertent start of the chain.
- Never carry or transport the chain saw with the chain
running.
- When the saw is hot, do not cover it (with a tarp,
blanket, newspaper or the like).
Let the saw cool down before putting it in a storage
case or vehicle. Saws with catalytic converter take
longer to cool down!
- When transporting the chain saw over long distances the
chain protection cover (delivered with the chain saw) must
be applied.
- Carry the chain saw with the tubular handle. The guide bar
points backwards (20). Avoid coming in contact with the
mufer (danger of burns).
- Ensure safe positioning of the chain saw during car trans-
portation to avoid fuel or chain oil leakage.
- Store the chain saw safely in a dry place. It must not be
stored outdoors. Keep the chain saw away from children.
The chain protection cover should always be put on.
- Before storing the chain saw over a long period of time
or shipping it the fuel and oil tanks must be completely
emptied.
Maintenance
- Before performing maintenance work switch off the
chain saw (21) and pull out the plug cap.
- Before starting work always check the operating safety of
the chain saw, in particular the function of the chain brake.
Make sure that the chain is always sharpened and tightened
correctly (22).
- Operate the chain saw only at a low noise and emission
level. For this ensure the carburetor is adjusted correctly.
- Regularly clean the chain saw.
- Regularly check the tank cap for tightness.
Observe the accident prevention instructions issued by
trade associations and insurance companies. Do not
perform any modications on the chain saw. You will
put your safety at risk.
Perform only the maintenance and repair works described in
the instruction manual. All other work must be carried out by
MAKITA Service.
Use only original MAKITA spare parts and accessories.
Using spare parts other than original MAKITA parts or
accesories and guide bar/chain combinations or lengths
which are not approved bring a high risk of accidents. We
cannot accept any responsibility for accidents and damage
resulting from using sawing devices or accesories which
have not been approved.

Engaging the chain brake (braking)
If the kickback is strong enough the sudden acceleration of
the guide bar combined with the inertia of the hand guard (1)
will automatically actuate the chain brake.
To engage the chain brake manually, simply push the hand
guard (1) forward (towards the tip of the saw) with your left
hand (arrow 1).
Releasing the chain brake
Pull the hand guard (1) towards you (arrow 2) until you feel it
catch. The brake is now released.
Chain brake
The EA3500F-EA4301F comes with an inertia chain brake as
standard equipment. If kickback occurs due to contact of the
guide-bar tip with wood (see SAFETY PRECAUTIONS), the
chain brake will stop the chain through inertia if the kickback
is sufciently strong.
The chain will stop within a fraction of a second.
The chain brake is installed to block the saw chain be-
fore starting it and to stop it immediately in case of an
emergency.
IMPORTANT: NEVER run the saw with the chain brake
activated (except for testing, see “Testing chain brake”)!
Doing so can very quickly cause extensive engine
damage!
ALWAYS release the chain brake
before starting the work!

19
Chain oil
Use an oil with adhesive additive for lubricating the chain and
guide bar. The adhesive additive prevents the oil from being
ung off the chain too quickly.
We recommend the use of chain oil which is bio-degradable
in order to protect the environment. The use of
bio-degradable oil may even be required by local regulations.
The chain oil BIOTOP sold by MAKITA is made of special
vegetable oils and is 100% bio-degradable. BIOTOP has
been granted the “blue angel” (Blauer Umweltschutz‑Engel)
for being particularly environment-friendly (RAL UZ 48).
BIOTOP chain oil is available in the following sizes:
1 l
5 l
Bio-degradable oil is stable only for a limited period
of time. It should be used within 2 years from the
date of manufacture (printed on the container).

Fuel
CAUTION:
This saw is powered by mineral-oil products (gasoline
and oil).
Be especially careful when handling gasoline .
Do not smoke. Keep tool well away from open ames,
spark, or re (explosion hazard).
Fuel mixture
This tool is powered by a high-performance air-cooled
two-stroke engine. It runs on a mixture of gasoline and
two-stroke engine oil.
The engine is designed for unleaded regular gasoline with
a min. octane value of 91 ROZ. In case no such fuel is
available, you can use fuel with a higher octane value. This
will not affect the engine.
In order to obtain an optimum engine output and to
protect your health and the environment use unleaded
fuel only.
To lubricate the engine, use a synthetic oil for two-stroke
air-cooled engines (quality grade JASO FD or ISO EGD),
which has to be added to the fuel. The engine has been
designed for use of MAKITA high-performance two-stroke
engine oil and a mixture ratio of only 50:1 to protect the
environment. In addition, a long service life and reliable
operation with a minimum emission of exhaust gases are
ensured.
MAKITA high-performance two-stroke engine oil is available
in the following sizes to suit your individual requirements:
1 l
100 ml
In case MAKITA high-performance two-stroke engine oil is
not available, it is urgently recommended to use a mixture
ratio of 50:1 with other two-stroke engine oils, as otherwise
optimum operation of the engine cannot be guaranteed.
Caution: Do not use ready-mixed fuel from petrol
stations.
The correct mixture ratio:
50:1 when using MAKITA high-performance two-stroke
engine oil, i. e. mix 50 parts gasoline with 1 part oil.
50:1 when using other synthetic two-stroke engine oils
(quality grade JASO FD or ISO EGD), i. e. mix 50
parts gasoline with 1 part oil.
NOTE:
For preparing the fuel‑oil mixture rst mix the entire oil
quantity with half of the fuel required, then add the remaining
fuel. Thoroughly shake the mixture before lling it into the
chain saw tank.
It is not wise to add more engine oil than
specied to ensure safe operation. This will only
result in a higher production of combus-tion
residues which will pollute the environment and
clog the exhaust channel in the cylinder as well
as the mufer. In addition, fuel consumption will
rise and performance will decrease.
The Storage of Fuel
Fuels have a limited storage life. Fuel and fuel
mixtures age through evaporation, especially at high
temperatures. Aged fuel and fuel mixtures can cause
starting problems and damage the engine.Purchase
only that amount of fuel, which will be consumed
over the next few months. At high temperatures,
once fuel has been mixed it should be used up in
6-8 weeks.
Store fuel only in proper containers, in dry, cool,
secure locations!
AVOID SKIN AND EYE CONTACT
Mineral oil products degrease your skin. If your skin
comes in contact with these substances repeatedly
and for an extended period of time, it will desiccate.
Various skin deseases may result. In addition,
allergic reactions are known to occur.
Eyes can be irritated by contact with oil. If oil comes
into your eyes, immediately wash them with clear
water.
If your eyes are still irritated, see a doctor
immediately!

Refuelling
FOLLOW THE SAFETY PRECAUTIONS!
Be careful and cautious when handling fuels.
The engine must be switched off!
Thoroughly clean the area around the caps, to prevent dirt
from getting into the fuel or oil tank.
Unscrew the tank cap (use the universal wrench if necessary,
see illustration) and ll tank with fuel mixture or saw chain
oil up to the bottom edge of the lling neck. Be careful not to
spill fuel or chain oil!
Screw on the tank cap by hand all the way.
Clean the tank cap and the area around the tank after
refuelling.
Lubricating the chain
During operation there must always be sufcient chain oil in
the chain-oil tank to provide good chain lubrication. At
medium oil feed rate, the oil tank holds enough for one
fuel tank’s worth of operation. During this procedure check
whether there is enough the chain oil in the tank and rell if
necessary. Do this only with the engine turned off! Screw
on the tank cap by hand all the way.
waste oil
NEVER USE WASTE OIL
Waste oil is very dangerous for the environment.
Waste oil contains high amounts of carcinogenic substances.
Residues in waste oil result in a high degree of wear and tear
at the oil pump and the sawing device.
In case of damage caused by using waste oil or
unappropriate chain oil the product guarantee will be null and
void.
Your salesman will inform you about the use of chain oil.
AVOID SKIN AND EYE CONTACT
Mineral oil products degrease your skin. If your skin comes in
contact with these substances repeatedly and for an
extended period of time, it will desiccate. Various skin de-
seases may result. In addition, allergic reactions are known
to occur.
Eyes can be irritated by contact with oil. If oil comes into your
eyes, immediately wash them with clear water.
If your eyes are still irritated, see a doctor immediately!
Important note on bio-degradable chain oils
If you are not planning to use the saw again for an
extended period of time, empty the oil tank and put in a
small amount of regular engine oil (SAE 30), and then
run the saw for a time. This is necessary to ush out all
remaining bio-degradable oil from the oil tank, oil-feed
system, chain and guide bar, as many such oils tend
to leave sticky residues over time, which can cause
damage to the oil pump or other parts.
The next time you use the saw, ll the tank with BIOTOP
chain oil again. In case of damage caused by using waste
oil or unappropriate chain oil the product guarantee will be
null and void.
Your salesman will inform you about the use of chain oil.
