Power chain saws
This power chain saw may be used only for sawing wood out
of doors. It is intended for the following uses depending on its class:
- Professional and mid-class: Use on small, medium and
large trees: felling, limb removal, cutting to length, thinning.
- Hobbyklasse: Occasional use on small trees, fruit‑tree care,
felling, limb removal, cutting to length.
Unauthorised users:
Persons who are not familiar with the Instruction Manual, children,
young people, and persons under the inuence of drugs, alcohol or medication must not use this saw.
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 insu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 be
come 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 gloves (6) made of thick leather are part of the
prescribed equipment and must always be worn during op eration 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 protec
tion for the leg must always to be worn. Safety shoes equipped
with a protective layer provide protection against cuts and
ensure a secure footing.

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 mus (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.

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 (environ‑
mental 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 tight‑
ening 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 as‑
sembled. Never use the chain saw when it is not completely assembled.
‑ Before starting the chain saw ensure that you have a safe foot
ing.
‑ Put the chain saw into operation only as described in this
instruction manual (8). Other starting methods are not al lowed.
‑ 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 o the chain saw immediately if you observe any
changes in its operating behavior.
The engine must be switched o 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 o the engine immediately and check the sawing device.
‑ When stopping work or leaving the working place switch o
the chain saw (9) and put it down such that nobody is endan‑
gered.
CAUTION: Do not put the overheated power chain
saw in dry grass or on any inammable objects. The mu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 center 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 longitudi-
nal cuts are to be performed it is urgently recommended
to have this carried out by specially trained persons
only (high risk of kickback). ‑ 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.

‑ 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.
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 foot ing (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.

Transport and storage
When changing your location during work switch o
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
guide bar 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.
‑ Before storing the chain saw over a long period of time or ship
ping it the fuel and oil tanks must be completely emptied.
20
Maintenance
Before performing maintenance work switch o 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 ac‑
cesories 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.
