Stop the engine before refuelling the chain saw.  
Do not smoke or work near open Þres (5).  
Let the engine cool down before refuelling.  
Fuels can contain substances similar to solvents. Eyes and skin  
shouldnotcomeincontactwithmineraloilproducts.Alwayswear  
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 im-  
mediately 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 ac-  
cumulate near the ßoor (explosion hazard).  
Ensure to Þrmly 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 pre-  
scriptions.  
Check especially the function of the chain brake, the correct  
mounting of the guide bar, the correct sharpening and tighten-  
ing of the chain, the Þrm 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.  
Putthechainsawonlyintooperationifitiscompletelyassembled.  
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 instruc-  
tion 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 tubu-  
lar handle with the left hand. Hold the handles tightly with your  
thumbs facing your Þngers.  
-
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 mal-  
functions (9).

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:  
-
Onlyspecially-trainedpersonsshouldperformplungecuts, i.e.,  
piercing timber or wood with the tip of the saw!  
10  
-
-
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.  
Ensurethatthechainisalwayssharpenedcorrectly.Payspecial  
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).  
11  
-
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.  
12  
13  
14  
-
-
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 saw-  
ing 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 Þrmly 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 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.  
Whenperformingseveralcutsthethrottlelevermustbereleased

-
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), Þrst 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.  
15  
CAUTION:  
Peoplefellingtreesorcuttingofbranchesmustbespecially  
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.  
16  
b) every worker involved can withdraw without stumbling (the  
people should withdraw backwards in a diagonal line, i. e.  
at a degree of 45°).  
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.  
2 1/2  
45°  
-
Judging the tree:  
Direction of hanging - loose or dry branches - height of the tree  
- natural overhang - is the tree rotten?  
= cutting down area  
-
Take into account the direction and speed of the wind. If strong  
gusts are occurring, do not do any felling.  
17  
-
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.  
18  
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.  
19  
-
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 inad-  
vertent start of the chain.  
-
-
Never carry or transport the chain saw with the chain run-  
ning.  
Whentransportingthechainsawoverlongdistancestheguide  
bar protection cover (delivered with the chain saw) must be  
applied.  
-
Carry the chain saw with the tubular handle. The guide bar  
pointsbackwards(20).Avoidcomingincontactwiththemufßer  
(danger of burns).  
20  
-
-
-
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.  
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 cor-  
rectly (22).  
21  
-
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 modiÞcations 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.  
22  
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.

Checking the chain tension  
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.

as standard equipment. If kickback occurs due to contact of the  
guide-bartipwithwood(seeSAFETYPRECAUTIONS,page6),  
the chain brake will stop the chain through inertia if the kickback  
is sufÞciently 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 emer-  
gency.  
IMPORTANT: NEVER run the saw with the chain brake acti-  
vated (except for testing, see “Testing chain brake”)! Doing so  
can very quickly cause extensive engine damage!  
ALWAYS release the chain brake  
before starting the saw!

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.

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.  
Thoroughly shake the mixture before Þlling it into the  
chain saw tank.  
To lubricate the engine, use a synthetic oil for two-stroke air-  
cooled engines (quality grade JASO FC 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 addi-  
tion, a long service life and reliable operation with a minimum  
emission of exhaust gases are ensured.  
It is not wise to add more engine oil than speciÞed  
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 mufßer. In  
addition, fuel consumption will rise and perform-  
ance will decrease.  
MAKITA high-performance two-stroke engine oil is available in  
the following sizes to suit your individual requirements:

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.  
Store fuel only in proper containers, in dry, cool,  
secure locations!  
Caution: Do not use ready-mixed fuel from petrol  
stations.  
AVOID SKIN AND EYE CONTACT  
The correct mixture ratio:  
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.

Chain oil  
Use an oil with adhesive additive for lubricating the chain and  
guide bar. The adhesive additive prevents the oil from being  
ßung off the chain too quickly.  
BIOTOP chain oil is available in the following sizes:  
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.

Important note on bio-degradable chain oils  
If you are not planning to use the saw again for an ex-  
tended 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 ßush 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, Þll 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.  
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.

Checking the chain lubrication  
Never work with the chain saw withoute sufÞcient chain lubri-  
cation. 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 sufÞcient, you will see a light oil trace be-  
cause oil will be ßung 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.  
C
Adjusting the chain lubrication  
The engine must be switched off.  
You can adjust the oil pump feed rate with the adjusting screw  
(1). The adjusting screw is on the bottom side of the housing.  
The oil pump comes factory-set to a medium feed rate.  
To adjust the supply rate, use a small screwdriver to turn the  
adjusting screw:  
Adjustment range about 90°

to the right for a faster  
to the left for a slower  
oil feed rate.  
Pick one of the three settings depending on the length of the  
guide bar.  
While working make sure there is enough chain oil in the tank.  
If necessary, add oil.  
D
To ensure troublefree operation of the oil pump the oil guide  
groove at the crank case (2) and the oil inlet bore in the guide  
bar (3) must be cleaned regularly.  
Note:  
After the saw has been turned off it is normal for residual chain

Adjusting the carburetor (only for EU-countries)  
CAUTION:  
Do not adjust the carburetor until the machine has been  
completely assembled and checked! Do not adjust the  
carburetor without a tachometer!  
Carburetor adjustment is necessary for optimum engine  
performance, for safer and more economical operation.  
Adjust the carburetor only with the engine warm, a clean  
air Þlter, and properly installed cutting tool.  
Carburetor adjustment may be done only by a MAKITA  
service centre. Improper adjustment can cause damage  
to the engine.  
In order to comply with new emissions legislation, limits have  
been placed on the carburetor adjusting screws (H) and (L).  
This limitation (to about 180 degrees) prevents an exces-  
sively rich mixture. This in turn ensures compliance with  
emissions rules as well as optimum engine performance and  
economical fuel consumption.  
S

L
You will need a tachometer (part No. 950 233 210) for op-  
timum adjustment. Exceeding the maximum permissible  
speed can lead to overheating and under-lubricating, and  
damage to the engine!  
Factory setting of adjusting screws (H) and (L): Turned out  
almost all the way (counterclockwise).  
Use a screwdriver (blade width 4 mm, part No. 944 340 001)  
to adjust the screws.  
4. Set maximum permissible speed  
Set the maximum speed by minimal adjustments of  
the adjusting screw (H) in accordance with the tech-  
nical speciÞcations. Turning the adjusting screw (H)  
clockwise increases the speed. Never exceed the  
maximum permissible speed!  
For proper adjustment, proceed as follows:  
For units with electronic engine speed limitation:  
No tachometer is necessary to determine the  
maximum permissible speed, since exceeding  
this speed will result in clearly audible ignition  
misses!  
Checking adjusting screw (H)  
Before starting the engine make sure that adjusting screw (H) is  
turned out counterclockwise until it reaches a noticeable stop.  
The limitations do not prevent excessively lean running!  
1. Start engine and let it warm up (3-5 minutes)  
2. Set idle  
3. Check acceleration  
5. Check idle speed  
4. Set maximum permissible speed  
5. Check idle speed  
Check the idle speed after setting the top speed (the  
cutting tool must not rotate!).  
Repeat the adjustment procedure starting at Step 2,  
until the engine runs with the correct idle speed, good  
acceleration, and maximum permissible speed.  
2. Set idle  
Set the idle speed per the technical speciÞcations.  
Turning the adjusting screw (S) in (clockwise) increases the  
idle speed. Turning it out (counter-clockwise) lowers the idle  
speed. The cutting tool must not rotate!  
3. Check acceleration  
When the throttle is pressed, the engine should go smoothly  
from idle to high speed.  
Turn adjusting screw (L) out (counterclockwise) in small  
increments until acceleration is good.

MAINTENANCE  
Sharpening the saw chain  
CAUTION:Beforedoinganyworkontheguidebarorchain,  
always switch off the engine and pull the plug cap off the  
spark plug (see „Replacing the spark plug“). Always wear  
protective gloves!  
The chain needs sharpening when:  
The sawdust produced when sawing damp wood looks like  
wood ßour.  
The chain penetrates the wood only under great pressure.  
The cutting edge is visibly damaged.  
The saw is pulled to the left or right when sawing. This is caused  
by uneven sharpening of the chain.  
Important: Sharpen frequently, but without removing too  
much metal!  
Generally, 2 or 3 strokes of the Þle will be enough.  
Have the chain resharpened at a service centre when you have  
already sharpened it yourself several times.

CAUTION:Topreventeyeinjury,alwaysweareyeprotection  
when cleaning the Þlter with compressed air!  
Do not use fuel to clean the air Þlter.  
Disengage the cover clasp (1) with the universal wrench and  
take off the cover (2).  
Push up the combination switch (3) (Choke position) to prevent  
dirt particles from falling into the carburetor.  
Unhook the clasp (4) in the direction of the arrow with a Þnger  
or the universal wrench.  
Pull the air Þlter (5) up and out.  
Take the pre-Þlter (5a) out of the cover (2).  
IMPORTANT: Cover the intake opening with a clean cloth to  
prevent dirt particles from getting into the carburetor.  
Choosing the right Þlter: The ßeece Þlter is for use in dry or  
dusty conditions. The nylon Þlter (available as accessory) is for  
use in damp conditions. The pre-Þlter keeps out sawdust, and  
prevents powder snow from getting in when working in winter.  
2
5a  
Pry apart the top and bottom of the air Þlter as shown in Fig-  
ure.  
Cleaning the ßeece Þlter: Carefully tap out dust or carefully  
blow out dust from the inside with compressed air. Do not  
brush the ßeece, as this will force dirt particles into the fabric.  
If the Þlter is very dirty, it can be washed in lukewarm water  
with regular dishwashing detergent. Note that the ßeece Þlter  
does not need to be cleaned until there is a noticeable loss of  
power. If cleaning the Þlter does not bring an improvement in  
performance, it is time to replace it.  
Cleaning the nylon Þlter: Use a soft brush or blow out dirt  
from the inside with compressed air. If the Þlter is very dirty, it  
can be washed in lukewarm water with regular dishwashing  
detergent. Clean frequently (several times a day) when working  
in very dusty or dirty conditions. Full engine power is possible  
only with a clean air Þlter!  
Cleaningthepre-Þlter:Whenthepre-Þlterbecomesdirty,wash  
it in lukewarm soapy water using standard dishwashing liquid.  
Let the air Þlter dry completely.  
Put the top and bottom sections back together.  
Place the pre-Þlter back in the cover.  
5
Before assembling the air Þlter, check the choke ßap for any dirt  
particles. If there are any, remove them with a brush.

CAUTION: If the air Þlter becomes damaged, replace imme-  
diately! Pieces of cloth or large dirt particles can destroy  
the engine!

Insert the air Þlter (5) and press the clasp (4) in the direction of  
the arrow until it engages.  
Move the combination switch (3) down and press the throttle (6)  
once all the way, to deactivate the half-throttle lock.  
Put the cover (2) back on and afÞx it with the cover clasps
