Intended use
Electric saws
This electric saw may be used only for sawing wood.
It is intended for occasional use in thin wood, caring
for fruit trees, felling, removing limbs, and trimming to
length.
Persons who may not sue the saw:
This saw must not be used by persons who are not
familiar with this instruction manual, children, young
people, or anyone under the influence of alcohol, drugs
or medication.
Chain saw safety warnings: DO NOT let comfort
or familiarity with product (gained from repeated
use) replace strict adherence to chain saw safety
rules. If you use this tool unsafely or incorrectly,
you can suffer serious personal injury.
1. Keep all parts of the body away from the saw
chain when the chain saw is operating. Before
you start the chain saw, make sure the saw

5. Always keep proper footing and operate the
chain saw only when standing on fixed, secure
and level surface. Slippery or unstable surfaces
such as ladders may cause a loss of balance or
control of the chain saw.
6. When cutting a limb that is under tension be
alert for spring back. When the tension in the
wood fibres is released the spring loaded limb may
strike the operator and/or throw the chain saw out of
control.
7. Use extreme caution when cutting brush and
saplings. The slender material may catch the saw
chain and be whipped toward you or pull you off
balance.
8. Carry the chain saw by the front handle with
the chain saw switched off and away from
your body. When transporting or storing the
chain saw always fit the guide bar cover. Proper
handling of the chain saw will reduce the likelihood
of accidental contact with the moving saw chain.
9. Follow instructions for lubricating, chain
tensioning and changing accessories.
Improperly tensioned or lubricated chain may either
break or increase the chance for kickback.
10. Keep handles dry, clean, and free from oil and
grease. Greasy, oily handles are slippery causing
loss of control.
11. Cut wood only. Do not use chain saw for
purposes not intended. For example: do not use
chain saw for cutting plastic, masonry or non-
wood building materials. Use of the chain saw for
operations different than intended could result in a
hazardous situation.
12. Causes and operator prevention of kickback:
Kickback may occur when the nose or tip of the
guide bar touches an object, or when the wood
closes in and pinches the saw chain in the cut. Tip
contact in some cases may cause a sudden reverse
reaction, kicking the guide bar up and back towards
the operator.
Pinching the saw chain along the top of the guide
bar may push the guide bar rapidly back towards the
operator.
Either of these reactions may cause you to lose
control of the saw which could result in serious
personal injury. Do not rely exclusively upon the
safety devices built into your saw.
As a chain saw user, you should take several steps
to keep your cutting jobs free from accident or injury.
Kickback is the result of tool misuse and/or incorrect
operating procedures or conditions and can be
avoided by taking proper precautions as given below:
- Maintain a firm grip, with thumbs and fingers
encircling the chain saw handles, with both
hands on the saw and position your body and
arm to allow you to resist kickback forces.
Kickback forces can be controlled by the operator,
if proper precautions are taken. Do not let go of the
chain saw.
- Do not overreach and do not cut above
shoulder height. This helps prevent unintended
tip contact and enables better control of the chain
saw in unexpected situations.
- Only use replacement bars and chains
specified by the manufacturer. Incorrect
replacement bars and chains may cause chain
breakage and/or kickback.
- Follow the manufacturer’s sharpening and
maintenance instructions for the saw chain.
Decreasing the depth gauge height can lead to
increased kickback.
Safety precautions
General precautions (Fig. 1)
- To ensure correct operation the user has to read
this instruction manual to make himself familiar with
the characteristics of the electric chain saw. Users
insufficiently informed will risk danger to themselves
as well as others due to improper handling.
- It is recommended only to lend the electric chain saw
to people who have proven to be experienced with
electric 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.
- Familiarize yourself with the use of an electric chain
saw by cutting off lengths from a log on a sawhorse.
- Children and young persons aged under 18 years
must not be allowed to operate the electric chain saw.
Persons over the age of 16 years may, however, use
the chain saw for the purpose of being trained while
under supervision of a qualified trainer.
- Use electric chain saws always with the utmost care
and attention.
- Operate the electric chain saw only if you are in
good physical condition. Perform all work calm and
carefully. The user has to accept liability for others.
- Never use the electric chain saw after the
consumption of alcohol or drugs or medication.
(Fig. 2)
Personal 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 electric 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.
- 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.If you have long hair wear a hairnet. (Fig. 3)
- The face shield 2 ( ) of the protective helmet (or the
goggles) protect against sawdust and wood chips.
During operation of the electric chain saw always
wear a goggle or a face shield to prevent eye injuries.
- Wear adequate noise protection equipment (ear
muffs ( ), ear plugs, etc.). Octave brand analysis 3
upon request.
- The protective brace and bib overall 4 ( ) is made of
a nylon structure with 22 layers and protects against
cuts. We strongly recommend its use. In any case
wear a long pair of trousers made of solid material
during operation of the electric chain saw. (Fig. 4)
- ( ) made of thick leather are part Protective gloves 5
of the prescribed equipment and must always be worn
during operation of the electric chain saw.
- During operation of the electric chain saw safety
shoes 6 or boots ( ) fitted with anti skid sole, steel toe
caps and protection for the leg are always to be used.
15
- Secure round timber.
- When working on slopes, always work facing the
slope.
- For performing crosscuts the toothed ledge (Z,
Fig. 12) 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 running. 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
tubular handle and simultaneously pulling backwards
the electric chain saw. Apply the toothed ledge a little
bit deeper and once again lift the back handle.
- 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 (Fig. 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.
- 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. (Fig. 14)
- If the timber is not free of tension , first cut (Fig. 15)
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).
- Never use the electric chain saw for lifting up or
removing pieces of wood or other objects.
- When releasing the tension the electric chain saw
should be supported on the trunk (risk of kickbacks).
- 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 connection.
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) all persons involved in the felling have an
unhindered retreat 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, 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. Before cutting down the tree (Fig. 16)
check the direction of fall and make sure that there
are neither other persons nor any objects within a
distance of 2 1/2 tree lengths. (Fig. 16)
=
Felling direction
= Danger zone
= Retreat path
- 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, ): Fig. 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.
- When correcting the cut always do so over the whole
width of the notch.
- Cut down the tree (B, ) above the bottom edge Fig. 18
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,
Fig. 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. (Fig. 19)
- 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
instructions:
- 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.
- Ensure that the chain is always sharpened correctly.
Pay special 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
16
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.
Transport and storage
- Carry the electric chain saw with the tubular handle.
The saw bar indicates backwards. Never carry or
transport the electric chain saw with the chain
running.
- Never carry the saw by the power cord. Do not
disconnect the plug by pulling on the power cord.
- When changing your position during work switch of
the electric chain saw and actuate the chain brake in
order to prevent an inadvertent start of the chain.
- When transporting the electric chain saw over long
distances the power supply plug must be pulled out
and the bar protection cover, included in the delivery,
must be applied. (Fig. 20)
- Ensure safe positioning of the electric chain saw
during car transportation to avoid oil leakage.
- Store the saw in a secure, dry, lockable room out of
reach of children. It must not be stored outdoors.
- For storing the electric chain saw over a long period
of time or shipping it the oil tank must be completely
emptied.
- Only use approved and marked containers for
transporting and storing chain oil.
Maintenance
- For performing maintenance works switch of
the electric chain saw, pull out the power supply
plug and secure it. (Fig. 21)
- Before starting to work, always make sure that the
saw is in safe working order, in particular the chain
brake and run-out brake. Make sure that the saw
chain is always sharpened and tightened correctly.
(Fig. 22)
- Have the chain brake and run-out brake inspected
regularly (see “Chain brake, run-out brake”).
- Regularly check the cable to the power supply for
damage of the covering.
- Regularly clean the electric chain saw.
- If the plastic case is damaged, have it immediately
repaired by a skilled person.
- Regularly check the tank cap for tightness.
- Do not use the saw if the ON/OFF switch is defective.
Have it repaired by a qualified person.
Observe the accident prevention instructions
issued by the competent trade federations and
insurance companies.
Do not perform any modifications on the electric
chain saw. You will endanger your safety.
Perform only the maintenance and repair works
described in the instruction manual. All other works
must be carried out by the MAKITA service. (Fig. 23)
Use only original MAKITA spare parts and
accessories.
Applying spare parts which are not original MAKITA
parts or accesories and bar/chain combinations
or lengths results in a high risk of accidents. For
accidents and damage resulting from using sawing
devices or accesories which have not been approved
we cannot accept any responsibility.
First aid (Fig. 24)
For the event of a possible accident, please, make sure
that a first aid box is always immediately available close
by. Immediately replace any items used from the first
aid box.
Should you ask for help, please, give the following
information:
- place of accident
- what happened
- number of injured persons
- kind of injuries
- your name.

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 ( ) firmly in the direction of the 6
arrow until you feel it catch. (Fig. 47)
Important:
These models are equipped with a starting current
limiter. This electronic component prevents too abrupt
starting of the electric motor.
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.
Checking the chain brake (Fig. 48)
Do not work with the chain saw without first
checking the chain brake!
- Start the motor as described (make sure you have a
good footing, and place the chain saw on the ground
in such a way that the guide bar is free of contact).
- Grasp the tubular handle firmly with one hand and
hold the grip with the other.
- Switch on the motor and press the hand guard ( ) in 1
the direction of the arrow with the back of your hand
until the chain brake engages. The chain should stop
immediately.
- Switch the motor off Immediately and release the
chain brake.
Important: If the saw chain does not stop
instantly when you carry out this test, do not
under any circumstances use the saw! Take the
chain saw to a MAKITA service center.
Testing the run-out brake (Fig. 49)
Do not work with the saw without first testing the
run-out brake!
- Start the motor as described (make sure you have a
good footing, and place the chain saw on the ground
in such a way that the guide bar is free of contact).
- Grasp the tubular handle firmly with one hand and
hold the grip with the other.
- Switch the motor on and then back off. The chain
should come to a full stop within two second of
switching off the motor.
Important: If the saw chain does not stop within
two second when you carry out this test, do not
use the saw! Inspect the carbon brushes.
Checking the chain lubrication (Fig. 50)
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 (Fig. 51)
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
pressure.
- 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: (Fig. 52)
CAUTION:
Use only chains and guide bars designed for this
saw!
- All cutters must be of the same length (dimension a).
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.
- 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 (.025”).
CAUTION:
Excessive depth increases the risk of kickback!
(Fig. 53)
- All cutters must be sharpened to the same angle, 30°.
Different angles result in a roughly, irregularly running
chain, increase wear and tear and cause chain
beakage. (Fig. 54)
- 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.
- The file should cut only when pushed forwards
(arrow). Lift the file when leading it backwards.
(Fig. 55)
- 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.

- 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. (Fig. 56)
- After having sharpened the chain, the height of the
depth limiter must be checked by means of a chain
gauge.
- Correct even the smallest excess height with a special
flat file ( ). 1
- Round off the front of the depth limiter (2). (Fig. 57)
Cleaning the guide bar, lubricating the
sprocket nose (Fig. 58)
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 clean the 2 mm thoroughly
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
accessories.
Multi-purpose grease (order no. 944 360 000)

Replacing the saw chain (Fig. 59)
CAUTION:
Use only chains and guide bars designed for this
saw!
Check the sprocket ( ) before mounting a new chain.1
CAUTION:
Worn out sprockets ( ) may damage the new chain and 2
must therefore be replaced.
Do not attempt to replace the sprocket yourself.
Sprocket replacement requires special training and
tools and must be done at a MAKITA service centre.

Inspecting and replacing the carbon brushes
(Fig. 61)
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
- If the wear limit has not yet been reached, put the
brush back in the same position and screw the cover
( ) back on.1
- Run the saw briefly (about a minute) so the brushes
can run in again.
Important: Now test the run-out brake. 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
functions properly.
NOTE: After installing new carbon brushes, run the saw
about 5 minutes and then check the run-out brake.
