SAFETY WARNINGS
General power tool safety warnings
WARNING: Read all safety warnings and
all instructions. Failure to follow the warnings and
instructions 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.
Work area safety
1. Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
2. Do not operate power tools in explosive atmo-
spheres, such as in the presence of ammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
3. Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
Electrical Safety
1. Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power
tools. Unmodied plugs and matching outlets will
reduce risk of electric shock.
2. Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of elec-
tric shock if your body is earthed or grounded.
3. Do not expose power tools to rain or wet con-
ditions. Water entering a power tool will increase
the risk of electric shock.
4. Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges
or moving parts. Damaged or entangled cords
increase the risk of electric shock.
5.
When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of a cord
suitable for outdoor use reduces the risk of electric shock.
6. If operating a power tool in a damp location is
unavoidable, use a ground fault circuit inter-
rupter (GFCI) protected supply. Use of a GFCI
reduces the risk of electric shock.
Personal Safety
1. Stay alert, watch what you are doing and use
common sense when operating a power tool.
Do not use a power tool while you are tired or
under the inuence of drugs, alcohol or med-
ication. A moment of inattention while operating
power tools may result in serious personal injury.
2. Use personal protective equipment. Always
wear eye protection. Protective equipment such
as a dust mask, non-skid safety shoes, hard hat or
hearing protection used for appropriate conditions
will reduce personal injuries.
3. Prevent unintentional starting. Ensure the
switch is in the o󰀨-position before connecting
to power source and/or battery pack, picking
up or carrying the tool. Carrying power tools with
your nger on the switch or energising power tools
that have the switch on invites accidents.
4. Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may
result in personal injury.
5. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
6. Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing, and gloves
away from moving parts. Loose clothes, jewel-
lery or long hair can be caught in moving parts.
7. If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
dust collection can reduce dust-related hazards.
Power tool use and care
1. Do not force the power tool. Use the correct
power tool for your application. The correct
power tool will do the job better and safer at the
rate for which it was designed.
2. Do not use the power tool if the switch does
not turn it on and o󰀨. Any power tool that cannot
be controlled with the switch is dangerous and
must be repaired.
3. Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such pre-
ventive safety measures reduce the risk of starting
the power tool accidentally.
4. Store idle power tools out of the reach of chil-
dren and do not allow persons unfamiliar with
the power tool or these instructions to operate
the power tool. Power tools are dangerous in the
hands of untrained users.
5. Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may a󰀨ect the
power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
6. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
7. Use the power tool, accessories and tool bits
etc. in accordance with these instructions, tak-
ing into account the working conditions and
the work to be performed. Use of the power tool
for operations di󰀨erent from those intended could
result in a hazardous situation.
Battery tool use and care
1. Recharge only with the charger specied by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of re
when used with another battery pack.
2. Use power tools only with specically desig-
nated battery packs. Use of any other battery
packs may create a risk of injury and re.

5ENGLISH
3. When battery pack is not in use, keep it away
from other metal objects, like paper clips,
coins, keys, nails, screws or other small metal
objects, that can make a connection from one
terminal to another. Shorting the battery termi-
nals together may cause burns or a re.
4.
Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact acci-
dentally occurs, ush with water. If liquid con-
tacts eyes, additionally seek medical help. Liquid
ejected from the battery may cause irritation or burns.
5. Do not use a battery pack or tool that is dam-
aged or modied. Damaged or modied batteries
may exhibit unpredictable behaviour resulting in
re, explosion or risk of injury.
6. Do not expose a battery pack or tool to re or
excessive temperature. Exposure to re or tem-
perature above 130 °C may cause explosion.
7. Follow all charging instructions and do not
charge the battery pack or tool outside the
temperature range specied in the instruc-
tions. Charging improperly or at temperatures
outside the specied range may damage the
battery and increase the risk of re.
Service
1.
Have your power tool serviced by a qualied repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.
2. Follow instruction for lubricating and chang-
ing accessories.
3.
Keep handles dry, clean and free from oil and grease.
4. Do not modify or attempt to repair the appli-
ance or the battery pack except as indicated in
the instructions for use and care.
Cordless 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 inatten-
tion while operating chain saws may cause entan-
glement 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 power tool 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 power tool
"live" and could give the operator an electric shock.
4. Wear safety glasses and hearing protection.
Further protective equipment for head, hands,
legs and feet is recommended. Adequate protec-
tive clothing will reduce personal injury by ying
debris or accidental contact with the saw chain.
5.
Do not operate a chain saw in a tree. Operation of a
chain saw while up in a tree may result in 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
such as ladders 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.
10. Follow instructions for lubricating, chain ten-
sioning and changing accessories. Improperly
tensioned or lubricated chain may either break or
increase the chance for kickback.
11. Keep handles dry, clean, and free from oil and
grease. Greasy, oily handles are slippery causing
loss of control.
12. Cut wood only. Do not use chain saw for pur-
poses 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 di󰀨erent than intended could result
in a hazardous situation.
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 tool misuse and/or incor-
rect 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 con-
trolled by the operator, if proper precautions
are taken. Do not let go of the chain saw.

6ENGLISH
• 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 bars and chains
specied 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.
14. Before starting work, check that the chain
saw is in proper working order and that its
condition complies with the safety regulations.
Check in particular that:
• The chain brake is working properly;
• The run-down brake is working properly;
• The bar and the sprocket cover are tted
correctly;
• The chain has been sharpened and ten-
sioned in accordance with the regulations.
15. Do not start the chain saw with the chain cover
being installed on it. Starting the chain saw with
the chain cover being installed on it may cause
the chain cover to thrown out forward resulting in
personal injury and damage to objects around the
operator.
16. Avoid dangerous environment. Don't use the
tool in damp or wet locations or expose it to
rain. Water entering the tool will increase the
risk of electric shock.
17. Do not dispose of the battery(ies) in a re. The
cell may explode. Check with local codes for
possible special disposal instructions.
18. Do not open or mutilate the battery(ies).
Released electrolyte is corrosive and may
cause damage to the eyes or skin. It may be
toxic if swallowed.
19. Do not charge battery in rain, or in wet
locations.
SAVE THESE INSTRUCTIONS.

Adjusting saw chain tension
CAUTION: Carry out the procedure of install-
ing or removing saw chain in a clean place free
from sawdust and the like.
CAUTION: Do not tighten the saw chain too
much. Excessively high tension of saw chain may
cause breakage of saw chain, wear of the guide bar
and breakage of the adjusting dial.
CAUTION: A chain which is too loose can
jump o󰀨 the bar and it may cause an injury
accident.
The saw chain may become loose after many hours
of use. From time to time check the saw chain tension
before use.

OPERATION
Lubrication
Saw chain is automatically lubricated when the tool is in
operation. Check the amount of remaining oil in the oil
tank periodically.
To rell the tank, lay the chain saw on its side and
remove the oil tank cap. The proper amount of oil is 200
ml. After relling the tank, make sure that the oil tank
cap is tightened securely.
12
► 1. Oil tank cap 2. Oil tank (translucent)
After relling, hold the chain saw away from the
tree. Start it and wait until lubrication on saw chain is
adequate.
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.
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.
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.

14 ENGLISH
Bucking
1. Rest the bottom edge of the chain saw body on
the wood to be cut.
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 cut-
ting, 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.
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.

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 train-
ing. 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.
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.

► 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;

15 ENGLISH
• 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
swellings. 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.

► 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.
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 horizontal. 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.
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 cartridges from the tool. Then
attach the guide bar cover. Also cover the battery car-
tridge with the 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.

16 ENGLISH
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)
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 several 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.
22

31
► 1. Cutter length 2. Distance between cutting edge
and depth gauge 3. Minimum cutter length (3 mm
(1/8"))
— 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 (1/8") 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 90PX : 0.65 mm (0.025″)
• Chain blade 91PX : 0.65 mm (0.025″)
• Chain blade 25AP : 0.65 mm (0.025″)
30

55 55
— 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.
• Chain blade 90PX : 55°
• Chain blade 91PX : 55°
• Chain blade 25AP : 55°
File and le guiding
— Use a special round le (optional accessory) for
saw chains to sharpen the chain. Normal round
les are not suitable.
— Diameter of the round le for each saw chain is as
follows:
• Chain blade 90PX : 4.5 mm (3/16″)
• Chain blade 91PX : 4.0 mm (5/32″)
• Chain blade 25AP : 4.0 mm (5/32″)
— The le should only engage the cutter on the for-
ward stroke. Lift the le o󰀨 the cutter on the return
stroke.
— Sharpen the shortest cutter rst. Then the length
of this shortest cutter becomes the standard for all
other cutters on the saw chain.
— Guide the le as shown in the gure.

— Round o󰀨 the front of the depth gauge again.
Cleaning the guide bar
Chips and sawdust will build up in the guide bar groove.
They may clog the bar groove and impair the oil ow.
Clean out the chips and sawdust every time when you
sharpen or replace the saw chain.
Cleaning the sprocket cover
Chips and saw dust will accumulate inside of the
sprocket cover. Remove the sprocket cover and saw
chain from the tool then clean the chips and saw dust.
Cleaning the oil discharge hole
Small dust or particles may be built up in the oil dis-
charge hole during operation. These dust or particles
may impair the oil to ow and cause an insu󰀩cient
lubrication on the whole saw chain. When a poor chain
oil delivery occurs at the top of guide bar, clean the oil
discharge hole as follows.
1. Remove the sprocket cover and saw chain from
the tool.
2. Remove the small dust or particles using a slotted
screwdriver or the like.
