In order to ensure the proper
functioning and performance of your
new chain saw, and to safeguard your
own personal safety, it is imperative
that you read this instruction manual
thoroughly before operation. Be
especially careful to observe all safety
precautions!
Failure to observe these precautions
can lead to severe injury or death!

14
Packing
Your MAKITA chain saw will be delivered in a protective
cardboard box to prevent transport damage.
Cardboard is a basic raw material and is consequently
reuse-able or suitable for recycling (waste paper
recycling).
SAFETY PRECAUTIONS
CAUTION:
This chain saw is designed especially for tree care
and surgery. All work with this chain saw is to be
carried out by properly trained persons only. Observe
all literature, procedures and recommendations from
the relevant professional organization. Failure to do
so constitutes a high accident risk! We recommend
always using a rising platform (cherry picker, lift) for
sawing in trees. Rappelling techniques are extremely
dangerous and require special training! The operator
must be trained in and familiar with the use of safety
equipment and working 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!
General precautions (Fig. 1 & 2)
-To ensure correct operation the user has to read
this instruction manual to make himself familiar with
the characteristics of the chain saw. Users insufficiently
informed will endanger themselves as well as others
due to improper handling.
- Lend this chain saw only to persons with training and
experience in the use of tree-surgery saws. Always
hand over the instruction manual.
- 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 qualified 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 work under the influence of alcohol, drugs or
medication.
- A fire extinguisher must be available in the immediate
vicinity when working in easily inflammable vegetation
or when it has not rained for a long time (danger of
fire).
Protective equipment (Fig. 3 & 4)
- 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 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.
-Theface 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.
-Theprotective jacket (4) 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.
-Theprotective brace and bib overall (5) is made of a
nylon fabric with 22 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) fitted 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.
Fuels/Refuelling
- Stop the engine before refuelling the chain saw.
- Do not smoke or work near open fires (Fig. 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.
- 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 at 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 floor (explosion hazard).
- Ensure to firmly tighten the screw caps of the fuel and
oil tanks.
- Change the place before starting the engine (at least
3 m from the place of refuelling) (Fig. 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. There must be someone
around in case of an emergency.
- Ensure that there are no children or other people within
the working area. Pay attention to any animals in the
working area, as well (Fig. 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 firm
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 (Fig. 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 rear handle with the right
hand and the tubular handle with the left hand. Hold the
handles tightly with your thumbs facing your fingers. It
is extremely dangerous to work with one hand, as the
saw can fall through the completed cut uncontrolled
(high risk of injury). Furthermore, it is impossible to
control kickback with one hand.
-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 (Fig. 9).
- When the sawing device is hit by stones, nails or other
hard objects, switch off the engine immediately and
check the sawing device.
- When stopping work or leaving the working place
switch off the chain saw (Fig. 9) and put it down such
that nobody is endangered.
- Do not put the overheated power chain saw in dry
grass or on any inflammable objects. The muffler is
very hot (danger of fire).
-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 (Fig. 10).
- Before the saw chain enters the cut, it can slip to the
side or jump (caution: high risk of kickback).
- 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!
- 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 (Fig. 11).
- Never saw while standing on a ladder (Fig. 11).
- Never climb a tree and work without the appropriate
restraining systems for the operator and the saw. We
recommend always working from a rising platform
(cherry picker, lift).
- 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
(Fig. 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, (Fig. 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.
- Before performing a crosscut firmly apply the front of
the body to the timber, only then can the timber be cut
with the chain running. For this the chain saw is lifted at
the rear handle and guided with the tubular handle. The
front of the body serves as a centre of rotation.
Continue by slightly pressing down the tubular handle
and simultaneously pulling back the chain saw. Apply
the front of the body a little bit deeper and once again
lift the rear handle.
-When the timber must be pierced for cutting or
longitudinal cuts are to be performed it is urgently

trained persons only (high risk of kickback).
-Dolongitudinal - lengthwise - cuts at the lowest
possible angle (Fig. 14). Be very careful when doing
this type of cut, as the front body 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 (Fig. 15).
- If the timber is under tension (Fig. 16), first 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 detentioning 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 (Fig. 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.
Avoid sawdust (pay attention to the direction the wind
is blowing)!
-Cutting the roots:
Start with the strongest root. First do the vertical and
then the horizontal cut.
-Notching the trunk (Fig. 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 (Fig. 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 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 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 (Fig. 20). Avoid coming in
contact with the muffler (danger of burns).
- Ensure safe positioning of the chain saw during car
transportation 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 shipping it the fuel and oil tanks must be completely
emptied.
Maintenance
-Before performing maintenance work switch off the
chain saw (Fig. 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 the saw chain is properly sharpened
and tensioned (Fig. 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 modifications 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.
(Fig. 23)
Use only original MAKITA spare parts and accessories.
Using spare parts other than original MAKITA parts or
accessories and guide bar/chain combinations or lengths
which are not approved bring a high risk of accidents.

Vibration
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.

PUTTING INTO OPERATION (Fig. 25)
CAUTION:
Before doing any work on the guide bar or chain,
always switch off the engine and pull the plug cap off
the spark plug (see “Replacing the spark plug”).
Always wear protective gloves!
CAUTION:
Do not start the saw until it has been completely
assembled and inspected!
Mounting the guide bar and saw chain (Fig. 26)
Use the universal wrench delivered with the chain saw for
the following work.
Put the chain saw on a stable surface and carry out the
following steps for mounting the guide bar and chain:
Disengage the chain brake by pulling the hand guard (1)
in the direction of the arrow.
Unscrew retaining nut (2).
Carefully spread the sprocket cover (3), pull it from its
fixture (4) and remove it.
Turn the chain adjusting screw (5) to the left
(counterclockwise) until the pin (6) is at the right stop.
(Fig. 27 & 28)
Position the guide bar (7). (Fig. 29)
Lift the chain (9) over the sprocket (10). Using your right
hand, guide the chain into the top guide groove (11) on
the guide bar. (Fig. 30)
Note that the cutting edges along the top of the chain
must point in the direction of the arrow!
Pull the chain (9) around the nose (12) of the guide bar in
the direction of the arrow.
Pull the guide bar by hand fully toward its nose. Make
sure that the chain blade fits the grooves of the guide bar.

First, push the sprocket cover (3) into its fixture (4). Make
sure that the pin (8) of the chain tightener is in the hole on
the guide bar. Then push it over the retaining bolt while
lifting the saw chain (9) over the chain catch (13).
Manually tighten the retaining nut (2). (Fig. 32)
Tightening the saw chain
Turn the chain adjusting screw (5) to the right (clockwise)
until the chain engages the guide groove of the bottom
side of the bar (see circle).
Slightly lift the end of the guide bar and turn the chain
adjusting screw (5) to the right (clockwise) until the chain
rests against the bottom side of the guide bar.
While still holding up the tip of the guide bar, tighten the
retaining nuts (2) with the universal wrench. (Fig. 33)
Checking the chain tension (Fig. 34)
The tension of the chain is correct if the chain rests
against the bottom side of the guide bar and can still be
easily turned by hand.
While doing so the chain brake must be released.
Check the chain tension frequently - new chains tend to
get longer during use! When checking the chain tension
the engine must be switched off.
NOTE:
It is recommended to use 2 - 3 chains alternatively.
In order to guarantee uniform wear of the guide bar the
bar should be turned over whenever replacing the chain.
Chain brake (Fig. 35)
The DCS230T and DCS232T come 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 sufficiently strong.
The chain will stop within a fraction of a second.
The chain brake is installed to block the saw chain
before starting it and to stop it immediately in case of
an emergency.
IMPORTANT: NEVER run the saw with the chain brake
activated! Doing so can very quickly cause extensive
engine damage!
NOTE:
The chain brake is a very important safety device and
like any other component subject to normal wear and
tear. Regular inspection and maintenance are
important for your own safety and must be done by a
MAKITA service centre.
Engaging the chain brake (braking) (Fig. 36)
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.
Fuel (Fig. 37)
CAUTION:
This saw is powered by mineral-oil products (gasoline
(petrol) and oil).
Be especially careful when handling gasoline (petrol).
Avoid all flame or fire. Do not smoke (explosion
hazard).
Fuel mixture
The engine of the chain saw is a high-efficiency 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.
For lubricating the engine use a two-stroke engine oil
(quality grade: JASO FC, ISO EGO), which is added to
the fuel.
Caution: Do not use ready-mixed fuel from petrol
stations.
The correct mixture ratio:
25:1 i.e. mix 25 parts gasoline with 1 part oil.
NOTE:
For preparing the fuel-oil mixture first mix the entire oil
quantity with half of the fuel required, then add the
remaining fuel. Shake the mixture thoroughly before
pouring it into the tank.
It is not wise to add more engine oil than specified to
ensure safe operation. This will only result in a higher
production of combustion residues which will pollute
the environment and clog the exhaust channel in the
cylinder as well as the muffler. 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. Therefore fuel and fuel mixtures, which have been
stored for too long, can cause starting problems.
Purchase only that amount of fuel, which will be
consumed over the next few months.
Store fuel safely in a dry place in approved containers
only.
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!
ALWAYS release the chain brake
before starting the work!

Chain oil
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).
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 flush 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, fill the tank with BIOTOP
chain oil again. In case of damage caused by using waste
oil or inappropriate chain oil the product guarantee will be
null and void.
Your salesman will inform you about the use of chain oil.
NEVER USE WASTE OIL (Fig. 38)
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 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 (Fig. 39)
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 cap and fill the tank with fuel (fuel/oil mixture)
or chain oil as the case may be. Fill up to the bottom edge
of the filler neck. Be careful not to spill fuel or chain oil!
Tighten the fuel caps far as it will go.
Clean screw cap and tank after refuelling.
Adjusting the chain lubrication (Fig. 40)
The engine must be switched off.
You can adjust the oil pump feed rate with the adjusting
screw (1). The amount of oil can be adjusted using the
universal wrench.
To ensure troublefree operation of the oil pump the oil
guide groove at the housing (2) and the oil inlet bore in the
guide bar (3) must be cleaned regularly. (Fig. 41)
Checking the chain lubrication (Fig. 42)
Never work with the chain saw without sufficient chain
lubrication. Otherwise the service life of the chain and
guide bar will be reduced.
Before starting work check the oil level in the tank and the
oil feed.
Check the oil feed rate as described below: Start the chain
saw (see “Starting the engine”).
Hold the running chain saw approx. 15 cm above a trunk
or the ground (use an appropriate base).
If the lubrication is sufficient, you will see a light oil trace
because oil will be flung off the sawing device. Pay
attention to the direction the wind is blowing and avoid
unnecessary exposure to the oil spray!
NOTE:
After the saw has been turned off it is normal for residual
chain oil to drip from the oil feed system, the guide bar
and the chain for a time. This does not constitute a defect!
Place the saw on a suitable surface.
Starting the engine (Fig. 43)
Do not start the saw until it has been completely
assembled and inspected!
Move at least 3 m away from the place where you fuelled
the saw.
Use an oil with adhesive additive for
lubricating the chain and guide bar. The
adhesive additive prevents the oil from
being flung 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.
BIOTOP chain oil is available in the
following sizes:
1 l order number 980 008 210
5 l order number 980 008 211
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).
Lubricating the chain
During operation there must always be
sufficient chain oil in the chain-oil tank to
provide good chain lubrication. One filling is
sufficient for about one half-hour of
continuous operation. When working, check
that there is still sufficient chain oil in the
tank and top up if necessary. Check only
when the engine is switched off!
