Working behavior/method of working  
9
-
-
-
Do not work on your own. There must be someone around in case  
of an emergency (within shouting distance).  
During sawing operation always hold the electric chain saw with  
both hands. Thus you will be able to guide it safely.  
Only use the electric chain saw during good light and visibility pe-  
riods. 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.  
Never saw while standing on a ladder.  
Never climb up into trees to perform sawing with the electric chain  
saw.  
Never bend forward by far to perform sawing.  
-
10  
5
-
Guide the electric chain saw in such a way that no part of your  
body is within the elongated swiveling range of the saw (11).  
-
-
Use the electric chain saw for sawing wood only.  
Do not let the chain touch the ground when it is running. If you  
are cutting wood lying directly on the ground, turn it over before  
completing the cut so that you do not cut into the ground.  
-
-
Clear the area of the cut of foreign objects such as sand, stones,  
nails, wire etc. Such objects can damage the blade and cause  
dangerous kickback.  
When sawing precut timber or thin woods use a safe support  
(sawing jack,1ꢀ). When sawing precut timber or thin pieces use  
a stable support (sawhorse, 1ꢀ). Do not saw stacked timber!  
Do not let another person steady the timber, and do not steady  
it with your foot!  
11  
-
-
Secure round timber.  
Z
When working on slopes, always work facing the slope.  
-
-
for performing crosscuts the toothed ledge (1ꢀ,Z) must be  
applied to the timber to be cut.  
Before performing a crosscut firmly apply the toothed ledge to  
the timber, only then can the timber be cut with the chain run-  
ning. For this the electric chain saw is lifted at the back handle  
and guided with the tubular handle. The toothed ledge serves  
as a center of rotation. Continue by slightly pressing down the  
tubularhandleandsimultaneouslypullingbackwardstheelectric  
chain saw. Apply the toothed ledge a little bit deeper and once  
again lift the back handle.  
1ꢀ  
-
-
-
The sawing device must be running whenever you remove the  
electric chain saw from the timber.  
When performing several cuts the electric chain saw must be  
switched off in between.  
When the timber must be pierced for cutting or longitudinal  
cuts are to be performed it is urgently recommended to  
have these works carried out by specially trained persons  
only (high risk of kickbacks).  
-
-
For performing longitudinal cuts (13) apply the sawing device  
at an angle which is as small as possible. Be very careful when  
carrying out this kind of work because the toothed ledge cannot  
be used.  
13  
When cutting with the bottom edge of the bar the electric chain  
saw may be pushed in the direction of the user if the chain is  
clamped. For this reason use the top edge of the bar whenever  
possible. The electric chain saw will then be pushed away from  
your body (14).  
-
If the timber is not free of tension (15), first cut the pressure  
side (A). Then the crosscut can be performed on the tension  
side (B). Thus clamping of the bar is avoided.  
-
-
-
-
-
Be very careful when cutting splintery wood. Cut pieces of wood  
may be pulled along (risk of injuries).  
Neverusetheelectricchainsawforliftinguporremovingpieces  
of wood or other objects.  
When releasing the tension the electric chain saw should be  
supported on the trunk (risk of kickbacks).  
14  
Tension releasing works must be carried out by trained  
persons. High risk of injuries.  
Be aware of branches under tension. Do not cut free branches  
from below.  
-
-
Never perform tension releasing works standing on the trunk.  
Do not use the electric chain saw for works in the forest, i.  
e. for cutting down trees or carrying out tension releasing  
works. The user's mobility and safety necessary for this  
kind of work are not guaranteed due to the cable connec-  
tion.  
15  
6
CAUTIon:  
Do not fell or debranch trees unless you are specially  
trained for it! There is a high risk of injury! Make sure to  
follow local regulations.  
Before cutting down a tree ensure that  
a) only those persons are within the working range which are  
actually involved in cutting down the tree

b) allpersonsinvolvedinthefellinghaveanunhinderedretreat  
route (the retreat path should be about 45° diagonally and  
to the rear away from the direction of fall). Be aware of the  
increased risk of stumbling from electric cables!  
c) the bottom part of the trunk is free from foreign bodies, un-  
derbrush and branches. Make sure to have a safe footing  
(risk of stumbling).  
= cutting down range  
16  
d) the next working place is at least ꢀ 1/ꢀ tree lengths away  
(16). Before cutting down the tree check the direction of fall  
and make sure that there are neither other persons nor any  
objects within a distance of ꢀ 1/ꢀ tree lengths (16).  
Judging the tree:  
Direction of hanging - loose or dry branches - height of the tree  
- natural hang over - is the tree rotten?  
Take into account the direction and the velocity of the wind.  
If strong gusts are occuring, do not perform any cutting down  
works.

Cutting the roots:  
Start with the strongest root. First perform the vertical and then  
the horizontal cut.  
Notching the trunk (A, 17):  
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.  
17  
-
When correcting the cut always do so over the whole width of  
the notch.  
-
-
Cut down the tree (B, 18) 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 the cut (B, 18) in good time.  
Secure the cut only with wedges made of plastic or aluminium.  
Do not use iron wedges.  
When cutting down a tree always stay sideways of the falling  
tree.  
When withdrawing after having performed the cut down be  
aware of falling branches.

When working on a sloping ground the user of the electric chain  
saw must stay above or sidewards of the trunk to be cut or the  
already cut down tree.

-
Be aware of trunks which may roll towards you.  
Kickback  
When working with the electric chain saw dangerous kickbacks  
may occur.  
-
-
-
Kickback occurs when the tip of the blade(especially the top  
quarter) inadvertently comes into contact with wood or other  
solid objects.  
In this case the electric chain saw is thrown without any control  
and with high energy potentials in the direction of the user (risk  
of injuries).  
In order to prevent kickbacks follow the indicated instruc-  
tions:  
-
-
Never apply the end of the bar when starting to make a cut.  
Always observe the end of the bar.  
Never use the bar end for sawing. Be careful when continuing  
to cut.  
-
-
When starting to perform a cut the chain must be running.  
Ensurethatthechainisalwayssharpenedcorrectly.Payspecial  
attention to the hight of the depth limiter (for detailed information  
see the chap. "Sharpening the saw chain").  
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. It  
is recommended to use a saw jack.

The chain has the proper tension when it lies against the bottom  
edge of the guide bar and can be easily pulled by hand about  
ꢀ-4 mm (about 1/8") up from the guide bar.  
Check the chain tension frequently - new chains tend to get  
longer during use!  
When checking the chain tension the motor must be switched  
off and the power supply plug pulled out. If the chain is too  
loose: Loosen the sprocket guard quick tightener by about a  
quarter turn. Tighten the chain as described under “Tightene-  
ing the saw chain.”  
HInT:  
Use ꢀ or 3 saw chains alternately for even wear of the chains,  
sprocket and guide bar running surfaces.  
In order to guarantee a uniform wear of the groove in the bar the  
bar should be turned over whenever replacing the chain.  
I
Chain brake  
The electric chain saw comes with an inertial chain brake as  
standard equipment. If kickback occurs due to contact of the  
guide-bartipwithwood(seeSAFETYPRECAUTIONS,page7),  
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.  
run-out brake  
The electric chain saw come with a run-out brake as standard  
equipment.  
The run-out brake ensures that the chain comes to a stop  
immediately when the ON/OFF switch is released, thus  
preventing the chain from continuing to run and presenting a  
hazard.  
Testing of the run-out brake is described on page 16.  
Chain and run-out brake maintenance  
The brake systems are very important safety features, and  
like any other part they are subject to a certain amount of  
wear. regular inspection and maintenance is important for  
your personal safety, and can be properly performed only  
by a MAKITA service centre.  
SErVICE  
J
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.

2
To engage the chain brake manually, simply push the hand  
guard (1) forward (towards the tip of the saw) with your left  
hand (arrow 2).  
1
releasing the chain brake  
Pull the hand guard (1) towards you (arrow 3) until you feel it  
catch. The brake is now released.  
note:  
When the chain brake is actuated the power supply to the  
motor will be cut off. Testing of the chain brake is described  
on page 16.

Saw chain oil  
BIOTOP oil is available in the following packing sizes  
to suit your individual requirements:  
Use a special oil with adhesive addition for lubricating the saw  
chain and bar. The adhesive addition prevents that the oil is  
centrifuged too fast from the sawing device.  
1 liter  
order number 980 008 610  
order number 980 008 611  
5 liters  
Do not use mineral oils. In order to protect the invironment the  
use of biologically decomposeable oil is prescribed.  
Biologically decomposeable oil is stable only for a  
limited period of time. It should be consumed within  
ꢀ years from the date of manufacture (printed on the  
container).  
The saw chain oil sold by MAKITA, called BIOTOP, is made  
of special vegetable oils and is biologically decomposeable to  
100%. BIOTOP has been granted the "blue angel" for being  
particularly favourable to the environment (RAL UZ 48).  
A
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 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 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.  
The residues in the waste oil result in a high degree of wear  
and tear at the oil pump and the sawing device.  
Waste oil  
Inthecaseofdamagecausedbyusingwasteoilorunappropriate  
saw chain oil the product guarantee will be null and void.  
Your salesman will inform you about the use of saw chain oil.  
AVoID SKIn AnD EyE ConTACTS  
Mineral oil products as well as oil degrease the skin. If your  
skin repeatedly comes in contact with these substances for a  
longer period of time, it will desiccate. Various skin deseases  
may result. In addition, allergic reactions are known.  
Eyes can be irritated by contact with oil. If oil gets into your eyes,  
immediately wash them with clear water. If your eyes are still  
irrritated, go to see a doctor.

-
Tightly screw on the tank cap.  
-
Thoroughly remove any oil that has overflown.  
Important!  
Before operating the saw for the first time, the oil feed system  
must be completely filled, until the chain oil lubricates the chain  
and guide bar.  
This procedure can take up to two minutes.  
-
The oil level can be controlled in the sight glass (2).  
In order to ensure sufficient lubrication of the saw chain there  
must always be enough oil in the tank.

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.  
Chain oil filter  
Dirt particles that accumulate on the chain oil filter will impede  
the flow of chain oil. This will eventually lead to poor lubrication,  
and faster wear to the chain and guide bar.  
If the chain is no longer getting enough lubrication, the chain  
oil filter (6) will need to be cleaned or replaced.  
-
Remove the sprocket guard, chain, and guide bar (see  
PUTTING INTO OPERATION).

Before connecting the saw to a source of electricity, al-  
ways make sure to check that when the on/off switch (1)  
has been pressed in and released, it automatically comes  
back out to the "off" position. If it does not, do not under  
any circumstances connect the saw to a power source -  
do not plug it in. Take the saw to a MAKITA service centre  
before doing any work with it.

-
Plug in the saw (see above).  
When switching on the electric 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 fingers. The bar and  
chain must not be in contact with any object.  
-
-
First depress the locking button (5) and then the power  
switch (1). Then release the locking button (5).  
Attention: The chain starts running immediately. Keep  
the power switch depressed as long as the motor is to run.

CAUTIon:  
never lock the power switch in the on position.  
Switching off the motor  
-
Release the power switch (1).  
noTE:  
When the chain brake is actuated the power supply to the  
motor will be cut off.  
If the saw does not start when the on/off switch (1) is  
actuated, it will be necessary to release the chain brake.  
-
Pull the hand guard (6) firmly in the direction of the arrow  
until you feel it catch.  
Important:  
These models are equipped with a starting current limiter.  
This electronic component prevents too abrupt starting of the  
electric motor.  
6
Excess current cutoff: When the electrical current to the saw  
exceeds the permissible level, the power supply to the motor  
is automatically cut off. This prevents overheating of the motor  
and resulting damage. To start the saw up again, release the  
ON/OFF switch and press it again.  
CAUTIon: Do not use the saw if the current cutoff repeatedly  
switches off the saw. Consult a MAKITA service centre.

Inspect the carbon brushes (see page 19).  
Checking the chain  
lubrication  
Never saw when a sufficient chain lubrication is not guaranteed.  
Otherwise the life of the sawing device will be reduced. Before  
starting work check the oil level in the tank and the oil feeding.  
Check the fed oil quantity by following the instructions below:  
-
-
Start the electric chain saw.  
Hold the running chain saw approx. 15 cm above a trunk or  
the ground (use an appropriate surface).  
If the lubrication is sufficient, you will see a light oiltrace because  
oil will be centrifuged from the chain saw. Pay attention to the  
direction the wind is blowing and avoid unnecessary exposure  
to the oil spray!

MAInTEnAnCE  
Sharpening the saw chain  
When working on the saw chain you must always pull out  
the power supply plug and wear protective gloves.  
The chain needs sharpening when:  
-
the sawdust from sawing humid wood looks like wood  
flour.  
-
the saw chain penetrates the wood only under great pres-  
sure.  
-
-
the cutting edge is visibly damaged.  
the sawing device is pulled to the left or the right during the  
sawing operation. This is caused by uneven sharpening of  
the chain or by damage to one side of it.  
Important: Sharpen frequently, but without removing  
too much metal!  
Generally, 2-3 strokes of the file will be enough.  
Have the chain resharpened in a service center when you  
have sharpened it yourself several times.  
Proper sharpening:  
CAUTIon:  
Use only chains and guide bars designed for this saw (see  
the Extract from the spare-parts list)!  
0,64 mm

-
Allcuttersmustbeofthesamelength(dimensiona). Cutters  
with different lengths result in rough running of the chain and  
can cause cracks in the chain.  
-
Minimum cutter length is 3 mm (0.11"). Do not resharpen the  
chain when the minimum cutter length has been reached;  
at this point, the chain must be replaced (see the Extract  
from the spare-parts list and "Replacing the chain").  
-
-
The depth of the cut is determined by the difference in height  
between the depth limiter (round nose) and the cutting  
edge.  
The best results are obtained with a depth-limiter depth of  
0.64 mm (.0ꢀ5").  
min.  
CAUTIon:  
3 mm (0.11”)  
Excessive depth increases the  
risk of kickback!  
-
-
All cutters must be sharpened to the same angle, 30°. Dif-  
ferent angles result in a roughly, irregularly running chain,  
increase wear and tear and cause chain beakage.  
The 85° front rake of the cutter results from the cut depth of  
the round file. If the proper file is used in the right manner,  
the correct front rake will be obtained automatically.

files and how to work with them  
-
Sharpen using a special file holder with a saw chain round  
file dia. 4.0 mm. Normal round files are not appropriate for  
this work. See "Accessories" for the order number.  
-
-
-
The file should cut only when pushed forwards (arrow). Lift  
the file when leading it backwards.  
First sharpen the shortest cutter. The length of this cutter is  
then the standerd for all other cutters of the chain.  
Always guide the file as in fig. shown  
4/5  
-
The file holder makes file guidance easier. It is marked for  
the correct 30° sharpening angle (keep the marks parallel  
with the chain when filing, see illustration) and limits the cut  
depth to the correct 4/5 of the file diameter. See "Acces-  
sories" for the order number.  
30°  
-
After having sharpened the chain, the height of the depth  
limiter must be checked by means of a chain gauge. See  
"Accessories" for the order number.

-
Correct even the smallest excess height with a special flat  
file (1). See "Accessories" for the order number.  
-
Round off the front of the depth limiter (2).  
B
Cleaning the guide bar,  
lubricating the sprocket nose  
CAUTIon: Protective gloves must be worn.  
Regularly inspect the bearing surfaces of the guide bar for  
damage, and clean them with a suitable tool.  
If the saw is used intensively it will be necessary to lubricate the  
return sprocket bearings regularly (once a week). To do this, first  
thoroughly clean the ꢀ mm hole at the tip of the guide bar, and  
then press in a small amount of multi-purpose grease.  
Multi-purpose grease and grease guns are available as acces-  
sories.

replacing the saw chain  
CAUTIon:  
Use only chains and guide bars  
designed for this saw (see the Extract from the spare parts  
list)!  
Check the sprocket (1) before mounting a new chain.  
CAUTIon:  
Worn out sprockets (2) may damage the new chain and must  
therefore be replaced.  
Do not attempt to replace the sprocket yourself. Sprocket re-  
placement requires special training and tools and must be done  
at a MAKITA service centre.

Inspecting and replacing the carbon brushes  
Important:  
Inspect the carbon brushes at regular intervals!  
A notch on the brush shows the limit of wear.  
noTE:  
The carbon brush is very delicate, so be careful not to let it  
drop. When taking it out, be sure to note the position it was  
installed in, since each brush is run in with the rotor.  
-
-
-
Use a slotted bit screwdriver to unscrew the cover (1), and  
then pull out the brush (2).  
Ifthewearlimithasnotyetbeenreached, putthebrushback  
in the same position and screw the cover (1) back on.  
Run the saw briefly (about a minute) so the brushes can run  
in again.  
Important: Now test the run-out brake (see page 16). If the  
saw chain does not come to a full stop within two second, run  
the saw again briefly and repeat the test until the brake func-  
tions properly.  
noTE: After installing new carbon brushes, run the saw about  
5 minutes and then check the run-out brake.
