SAFETY WARNINGS
General power tool safety warnings
WARNING: Read all safety warnings, instruc-
tions, illustrations and specications provided
with this power tool. Failure to follow all instructions
listedbelowmayresultinelectricshock,reand/or
seriousinjury.
Save all warnings and instruc-
tions for future reference.
The term "power tool" in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.
General chain saw safety warnings
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
chain is not contacting anything. A moment of
inattention while operating chain saws may cause
entanglement of your clothing or body with the
saw chain.
2. Always hold the chain saw with your right
hand on the rear handle and your left hand on
the front handle. Holding the chain saw with a
reversedhandcongurationincreasestheriskof
personalinjuryandshouldneverbedone.
3. Hold the chain saw by insulated gripping sur-
faces only, because the saw chain may contact
hidden wiring. Saw chains contacting a "live"
wire may make exposed metal parts of the chain
saw "live" and could give the operator an electric
shock.
4. Wear eye protection. Further protective equip-
ment for hearing, head, hands, legs and feet is
recommended. Adequate protective equipment
willreducepersonalinjuryfromyingdebrisor
accidental contact with the saw chain.
5. Do not operate a chain saw in a tree, on a lad-
der, from a rooftop, or any unstable support.
Operation of a chain saw in this manner could
resultinseriouspersonalinjury.
6.
Always keep proper footing and operate the chain
saw only when standing on xed, secure and
level surface. Slippery or unstable surfaces may
cause a loss of balance or control of the chain saw.
7. When cutting a limb that is under tension, be
alert for spring back. When the tension in the
woodbresisreleased,thespringloadedlimb
may strike the operator and/or throw the chain
saw out of control.
8.
Use extreme caution when cutting brush and sap-
lings. The slender material may catch the saw chain
andbewhippedtowardyouorpullyouo󰀨balance.
9. Carry the chain saw by the front handle with
the chain saw switched o󰀨 and away from your
body. When transporting or storing the chain
saw, always t the guide bar cover. Proper
handling of the chain saw will reduce the likelihood
of accidental contact with the moving saw chain.

12 ENGLISH
10. Follow instructions for lubricating, chain
tensioning and changing the bar and chain.
Improperly tensioned or lubricated chain may
either break or increase the chance for kickback.
11. Cut wood only. Do not use chain saw for pur-
poses not intended. For example: do not use
chain saw for cutting metal, plastic, masonry
or non-wood building materials. Use of the
chainsawforoperationsdi󰀨erentthanintended
could result in a hazardous situation.
12. Do not attempt to fell a tree until you have an
understanding of the risks and how to avoid
them.Seriousinjurycouldoccurtotheoperatoror
bystanders while felling a tree.
13. 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 chain saw misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below:
• Maintain a rm grip, with thumbs and
ngers 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 precau-
tions are taken. Do not let go of the chain
saw.
►Fig.1
• Do not overreach and do not cut above
shoulder height. This helps prevent unin-
tended tip contact and enables better control
of the chain saw in unexpected situations.
• Only use replacement guide bars and saw
chains specied by the manufacturer.
Incorrect replacement guide bars and saw
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.
14. Follow all instructions when clearing jammed
material, storing or servicing the chain saw.
Make sure the switch is o󰀨 and the battery
pack is removed. Unexpected actuation of the
chainsawwhileclearingjammedmaterialor
servicingmayresultinseriouspersonalinjury.

OPERATION
Lubrication
CAUTION: Do not operate the chain saw when
the tank is empty. Replenish the oil in due time
before the tank is empty.
CAUTION: Prevent the oil from coming into
contact with the skin and eyes. Contact with the
eyes causes irritation. In the event of eye contact,
ush the a󰀨ected eye immediately with clear
water, then consult a doctor at once.
CAUTION: Never use waste oil. Waste oil con-
tains carcinogenic substances. The contaminants
in waste oil cause accelerated wear of the oil
pump, the bar and the chain. Waste oil is harmful
to the environment.

17 ENGLISH
NOTICE: When the chain saw is used for the rst
time, it may take up to two minutes for the saw
chain oil to begin its lubricating e󰀨ect upon the
saw mechanism. Run the saw without load until
it does so.
NOTICE: When lling the chain oil for the rst
time, or relling the tank after it has been com-
pletely emptied, add oil up to the bottom edge of
the ller neck. The oil delivery may otherwise be
impaired.
NOTICE: Use the saw chain oil exclusively for
Makita chain saws or equivalent oil available in
the market.
NOTICE: Never use oil including dust and parti-
cles or volatile oil.
NOTICE: When pruning trees, use botanical oil.
Mineral oil may harm trees.
NOTICE: Before the cutting operation, make sure
that the provided oil tank cap is screwed in place.
Saw chain is automatically lubricated when the tool is in
operation. Check the amount of remaining oil in the oil
tank periodically through the oil inspection window.
►Fig.18: 1. Oil tank cap 2. Oil inspection window
Tolltheoil,performthefollowingsteps:
1. Clean the area around the oil tank cap thoroughly
to prevent any dirt from entering the oil tank.
2. Lay the chain saw on its side.
3. Push the button on the oil tank cap so that the

Working with the chain saw
CAUTION: The rst time user should, as a
minimum practice, do cutting logs on a saw-horse
or cradle.
CAUTION: When sawing precut timber, use a
safe support (saw horse or cradle). Do not steady
the workpiece with your foot, and do not allow
anyone else to hold or steady it.
CAUTION: Secure round pieces against
rotation.
CAUTION: Keep all parts of the body away
from the saw chain when the motor is operating.
CAUTION: Hold the chain saw rmly with
both hands when the motor is running.
CAUTION: Do not overreach. Keep proper
footing and balance at all times.
NOTICE: Never toss or drop the tool.
NOTICE: Do not cover the vents of the tool.
Bring the bottom edge of the chain saw body into
contact with the branch to be cut before switching on.
Otherwise it may cause the guide bar to wobble, result-
ingininjurytooperator.Sawthewoodtobecutbyjust
moving it down by using the weight of the chain saw.
►Fig.22
If you cannot cut the timber right through with a single
stroke:
Apply light pressure to the handle and continue sawing
and draw the chain saw back a little; then apply the
spikebumperalittlelowerandnishthecutbyraising
the handle.
►Fig.23
Bucking
1. Rest the bottom edge of the chain saw body on
the wood to be cut.
►Fig.24
2. With the saw chain running, saw into the wood
while using the rear handle to raise the saw and the
front one to guide it. Use the spike bumper as a pivot.
3. Continue the cut by applying slight pressure to
the front handle, easing the saw back slightly. Move
the spike bumper further down the timber and raise the
front handle again.
NOTICE: When making several cuts, switch the
chain saw o󰀨 between cuts.
CAUTION: If the upper edge of the bar is used
for cutting, the chain saw may be deected in
your direction if the chain becomes trapped. For
this reason, cut with the lower edge, so that the
saw will be deected away from your body.
►Fig.25
When you cut a wood under tension, cut the pressured
side(A)rst.Thenmakethenalcutfromthetensioned
side (B). This prevents the bar from becoming trapped.
►Fig.26

18 ENGLISH
Limbing
CAUTION: Limbing may only be performed by
trained persons. A hazard is presented by the risk
of kickback.
When limbing, support the chain saw on the trunk if possible. Do
not cut with the tip of the bar, as this presents a risk of kickback.
Pay particular attention to branches under tension. Do
not cut unsupported branches from below.
Do not stand on the felled trunk when limbing.
Burrowing and parallel-to-grain cuts
CAUTION: Burrowing and parallel-to-grain
cuts may only be carried out by persons with
special training. The possibility of kickback presents
ariskofinjury.
Perform parallel-to-grain cuts at as shallow an angle as
possible. Take an extra caution when carrying out the
cut as the spike bumper cannot be used.
►Fig.27
Felling
CAUTION: Felling work may only be per-
formed by trained persons. The work is hazardous.
Observe local regulations if you wish to fell a tree.
►Fig.28: 1. Felling area
— Before starting felling work, ensure that:
• Only persons involved in the felling operation
are in the vicinity;
• Any person involved has an unhindered path
of retreat through a range of approximately
45° either side of the felling axis. Consider
the additional risk of tripping over electrical
cables;
• The base of the trunk is free of foreign
objects,rootsandranches;
• Nopersonsorobjectsarepresentovera
distance of 2 1/2 tree lengths in the direction
in which the tree will fall.
— Consider the following with respect to each tree:
• Direction of lean;
• Loose or dry branches;
• Height of the tree;
• Natural overhang;
• Whether or not the tree is rotten.
— Consider the wind speed and direction. Do not
carry out felling work if the wind is gusting strongly.
—
Trimming of root swellings: Begin with the largest swell-
ings.Maketheverticalcutrst,thenthehorizontalcut.
— Stand to the side of the falling tree. Keep an area
clear to the rear of the falling tree up to an angle of
45° either side of the tree axis (refer to the “felling
area”gure).Payattentiontofallingbranches.
— An escape path should be planned and cleared
as necessary before cuts are started. The escape
path should extend back and diagonally to the rear
oftheexpectedlineoffallasillustratedingure.
►Fig.29: 1. Felling direction 2. Danger zone
3. Escape route
When felling trees, follow the procedures below:
1. Cut a scarf as close to the ground as possible.
First make the horizontal cut to a depth of 1/5 -1/3 of the
trunk diameter. Do not make the scarf too large. Then
make the diagonal cut.
►Fig.30
NOTE: The scarf determines the direction in which
the tree will fall, and guides it. It is made on the side
towards which the tree is to fall.
2. Make the back cut a little higher than the base
cut of the scarf. The back cut must be exactly horizon-
tal. Leave approximately 1/10 of the trunk diameter
betweenthebackcutandthescarf.Thewoodbersin
the uncut trunk portion act as a hinge. Insert wedges
into the back cut in time.
►Fig.31
WARNING: Do not cut right through the bers
under any circumstances. The tree will otherwise
fall unchecked.
NOTICE: Only plastic or aluminum wedges may
be used to keep the back cut open. The use of
iron wedges is prohibited.
Carrying tool
Before carrying the tool, always apply the chain brake
and remove the battery cartridge from the tool. Then
attach the guide bar cover. Also cover the battery car-
tridge with the battery cover.
►Fig.32: 1. Guide bar cover 2. Battery cover
MAINTENANCE
CAUTION: Always be sure that the tool is
switched o󰀨 and the battery cartridge is removed
before attempting to perform inspection or
maintenance.
CAUTION: Always wear gloves when perform-
ing any inspection or maintenance.
NOTICE: Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.
To maintain product SAFETY and RELIABILITY,
repairs,anyothermaintenanceoradjustmentshould
be performed by Makita Authorized or Factory Service
Centers, always using Makita replacement parts.
Sharpening the saw chain
Sharpen the saw chain when:
•
Mealy sawdust is produced when damp wood is cut;
• Thechainpenetratesthewoodwithdi󰀩culty,even
when heavy pressure is applied;
• The cutting edge is obviously damaged;
• The saw pulls to the left or right in the wood.
(caused by uneven sharpening of the saw chain or
damage to one side only)

19 ENGLISH
Sharpen the saw chain frequently but a little each time. Two
orthreestrokeswithaleareusuallysu󰀩cientforroutine
resharpening. When the saw chain has been resharpened sev-
eral times, have it sharpened in our authorized service center.
Sharpening criteria:
WARNING: An excessive distance between
the cutting edge and depth gauge increases the
risk of kickback.
►Fig.33: 1. Cutter length 2. Distance between cutting
edge and depth gauge 3. Minimum cutter
length (3 mm)
— Allcutterlengthmustbeequal.Di󰀨erentcutter
lengths prevent the saw chain from running
smoothly and may cause the saw chain to break.
— Do not sharpen the chain when the cutter length
has reached 3 mm or shorter. The chain must be
replaced with new one.
—
The chip thickness is determined by the distance between
the depth gauge (round nose) and the cutting edge.
— The best cutting results are obtained with following
distance between cutting edge and depth gauge.
• Chain blade 91PX : 0.65 mm
• Chain blade 80TXL : 0.65 mm
►Fig.34
— The sharpening angle of 30° must be the same on
allcutters.Di󰀨erentcutteranglescausethechain
to run roughly and unevenly, accelerate wear, and
lead to chain breaks.
— Useasuitableroundlesothatthepropersharp-
ening angle is kept against the teeth.
