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, fire and/or
serious injury.
Save all warnings and
instructions 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
atmospheres, such as in the presence of
flammable 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
4. 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. Unmodified plugs and matching outlets will
reduce risk of electric shock.
5. Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of
electric shock if your body is earthed or grounded.
Page: 3
4
6. Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
7. 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.
8. 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.
9. If operating a power tool in a damp location is
unavoidable, use a ground fault circuit
interrupter (GFCI) protected supply. Use of an
GFCI reduces the risk of electric shock.
Personal safety
10. 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 influence of drugs, alcohol or
medication. A moment of inattention while
operating power tools may result in serious
personal injury.
11. Use personal protective equipment. Always
wear eye protection. Protective equipment such
as dust mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate conditions
will reduce personal injuries.
12. Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to power source and/or battery pack, picking
up or carrying the tool. Carrying power tools
with your finger on the switch or energising power
tools that have the switch on invites accidents.
13. 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.
14. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
15. Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing, and gloves
away from moving parts. Loose clothes,
jewellery or long hair can be caught in moving
parts.
16. 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
17. 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.
18. Do not use the power tool if the switch does
not turn it on and off. Any power tool that
cannot be controlled with the switch is dangerous
and must be repaired.
19. 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
preventive safety measures reduce the risk of
starting the power tool accidentally.
20. Store idle power tools out of the reach of
children 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.
21. Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
22. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
23. Use the power tool, accessories and tool bits
etc. in accordance with these instructions,
taking into account the working conditions
and the work to be performed. Use of the
power tool for operations different from those
intended could result in a hazardous situation.
Battery tool use and care
24. Recharge only with the charger specified by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of fire
when used with another battery pack.
25. Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and fire.
26. 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
terminals together may cause burns or a fire.
27. Under abusive conditions, liquid may be
ejected from the battery; avoid contact. If
contact accidentally occurs, flush with water.
If liquid contacts eyes, additionally seek
medical help. Liquid ejected from the battery
may cause irritation or burns.

Service
28. Have your power tool serviced by a qualified
repair person using only identical
replacement parts. This will ensure that the
safety of the power tool is maintained.
29. Follow instruction for lubricating and
changing accessories.
30. Keep handles dry, clean and free from oil and
grease.
GEB118-1
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
inattention while operating chain saws may cause
entanglement of your clothing or body with the
saw chain.
2. When holding with both hands, 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
configuration increases the risk of personal injury
and should never be done.
3. Hold the power tool by insulated gripping
surfaces 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
protective clothing will reduce personal injury by
flying debris or accidental contact with the saw
chain.
5. Always keep proper footing. Slippery or
unstable surfaces 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 fibers 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.
014673
Page: 5
6
− 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.
13. 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 fitted
correctly;
• The chain has been sharpened and tensioned
in accordance with the regulations;
14. 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.

the chain saw.
9. Hold the saw firmly in place to avoid skating (skid
movement) or bouncing of the saw when starting
a cut.
10. At the end of the cut, be careful to keep your
balance due to the “drop”.
11. Take into account the direction and speed of the
wind. Avoid sawdust and chain oil mist.
Protective equipment
1. 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 chain saw:
− The kind of clothing should be appropriate, i.
e. it should be tight-fitting but not be a
hindrance. Do not wear jewelry or clothing
which could become entangled with bushes
or shrubs. If you have long hair, always wear
a hairnet!
− It is necessary to wear a protective helmet
whenever working with the chain saw. The
protective helmet 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.
− The face shield of the protective helmet (or
the goggles) protects against sawdust and
wood chips. During operation of the chain
saw always wear a goggle or a face shield to
prevent eye injuries.
− Wear adequate noise protection
equipment. (ear muffs, ear plugs, etc.)
− The protective jacket consists of 22 layers
of nylon and protects the operator against
cuts. It is always to be worn when working
from elevated platforms (cherry pickers, lifts),
from platforms mounted on ladders or when
climbing with ropes.
− The protective brace and bib overall is
made of a nylon fabric with 22 layers and
protects against cuts. We strongly
recommend its use.
− Protective gloves made of thick leather are
part of the prescribed equipment and must
always be worn during operation of the chain
saw.
Page: 6
7
− During operation of the chain saw safety
shoes or safety boots fitted with anti skid
sole, steel toe caps and protection for the leg
must always to be worn. Safety shoes
equipped with a protective layer provide
protection against cuts and ensure a secure
footing. For working in trees the safety boots
must be suitable for climbing techniques.
Vibration
1. Individuals with poor circulation who are exposed
to excessive vibration may experience injury to
blood vessels or the nervous system. Vibration
may cause the following symptoms to occur in the
fingers, hands or wrists: “Falling asleep”
(numbness), tingling, pain, stabbing sensation,
alteration of skin colour or of the skin. If any of
these symptoms occur, see a physician! To
reduce the risk of “white finger disease”, keep
your hands warm during operation and well
maintain the equipment and accessories.

014655
Saw chain is automatically lubricated when the tool is in
operation.
Check the amount of remaining oil in the oil tank
through the oil inspection window.
To refill the tank, remove the cap from the oil tank
opening.
After refilling the tank, always screw the provided oil
tank cap on the chain saw.
CAUTION:
• When filling the chain saw with chain oil for the
first time, or refilling the tank after it has been
completely emptied, add oil up to the bottom edge
of the filler neck. The oil delivery may otherwise be
impaired.
• As a saw chain oil, use oil exclusively for Makita
chain saws or oil available in market.
• Never use oil including dust and particles or
volatile oil.
• When pruning trees, use botanical oil. Mineral oil
may harm trees.
• Never force the chain saw when pruning trees.
• Before cutting out, make sure that the provided oil
tank cap is screwed in place.

Bring the spike bumper into contact with the branch to
be cut before switching on. Otherwise it may cause the
guide bar to wobble, resulting in injury to operator.
Saw the wood to be cut by just moving it down.
WORKING WITH THE CHAIN SAW
CAUTION:
• The first time user should, as a minimum practice,
do cutting logs on a saw-horse or cradle.
• 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.
• Secure round pieces against rotation.

CAUTION:
• Keep all parts of the body away from the saw
chain when the motor is operating.
• Hold the chain saw firmly with both hands when
the motor is running.
• Do not overreach. Keep proper footing and
balance at all times.
Bring the spike bumper into contact with the branch to
be cut before switching on. Cutting without bringing the
spike bumper into contact with the branch may cause
the guide bar to wobble, resulting in injury to operator.

When cutting thick branches, first make a shallow
undercut and then make the finish cut from the top.
001742
If you try to cut off thick branches from the bottom, the
branch may close in and pinch the saw chain in the cut.
If you try to cut off thick branches from the top without a
shallow undercut, the branch may splinter.
014714
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 a little lower and finish the cut by raising the
handle.
Bucking
014667
For bucking cuts, rest the spike bumper shown in the
figure on the wood to be cut.
With the saw chain running, saw into the wood, using
the top handle to raise the saw and the front one to
guide it. Use the spike bumper as a pivot.
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.
When making several cuts, switch the chain saw off
between cuts.

CAUTION:
• If the upper edge of the bar is used for cutting, the
chain saw may be deflected in your direction if the
chain becomes trapped. For this reason, cut with
the lower edge, so that the saw will be deflected
away from your body.

006915
Cut wood under tension on the pressure side (A) first.
Then make the final cut on the tension 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 kick-
back.
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.
014713
Perform parallel-to-grain cuts at as shallow an angle as
possible. Carry out the cut as carefully as possible, as
the spike bumper cannot be used.
Felling
CAUTION:
• Felling work may only be performed by trained
persons. The work is hazardous.
Observe local regulations if you wish to fell a tree.

− Before starting felling work, ensure that:
(1) Only persons involved in the felling operation
are in the vicinity;
(2) 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;
(3) The base of the trunk is free of foreign
objects, roots and ranches;
(4) 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 first, then the
horizontal cut.
1. Felling area
Page: 14

006918
− Cut a scarf: 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. Cut the
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.
− Cut any corrections to the scarf across its entire
width.
006923
− 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 fibers in the uncut trunk portion act as a
hinge. Do not cut right through the fibers under
any circumstances, as the tree will otherwise fall
unchecked. Insert wedges into the back cut in time.
− Only plastic or aluminum wedges may be used to
keep the back cut open. The use of iron wedges is
prohibited.
− 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 " figure). 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 figure.

Sharpen the saw chain when:
− Mealy sawdust is produced when damp wood is cut;
− The chain penetrates the wood with difficulty, even
when heavy pressure is applied;
− The cutting edge is obviously damaged;
− The saw pulls to the left or right in the wood. The
reason for this behaviour is uneven sharpening of
the saw chain, or damage to one side only.
Sharpen the saw chain frequently, but remove only
a little material each time.
Two or three strokes with a file are usually sufficient for
routine resharpening. When the saw chain has been
resharpened several times, have it sharpened in a
MAKITA specialist repair shop.
Sharpening criteria:
− All cutter length must be equal. Cutters of differing
length prevent the chain from running smoothly,
and may cause the chain to break.
− Do not sharpen the chain once a minimum cutter
length of 3 mm has been reached. A new chain
must then be fitted.
− 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: 0.5 mm
Chain blade 91PX: 0.65 mm
Chain blade 25AP: 0.65 mm

1 1
3 1
014456
WARNING:
• An excessive distance increases the risk of kick-
back.
− The sharpening angle of 30 ° must be the same on
all cutters. Differences in angle cause the chain to
run roughly and unevenly, accelerate wear, and
lead to chain breaks.
− The side plate angle of the cutter is determined by
the depth of penetration of the round file. If the
specified file is used properly, the correct side
plate angle is produced automatically.
− Side plate angle for each saw chain are as follows:
Chain blade 90PX: 75 °
Chain blade 91PX: 80 °
Chain blade 25AP: 85 °

File and file guiding
− Use a special round file (optional accessory) for
saw chains to sharpen the chain. Normal round
files are not suitable.
− Diameter of the round file for each saw chain is as
follows:
Chain blade 90PX: 4.5 mm
Chain blade 91PX: 4.0 mm
Chain blade 25AP: 4.0 mm
− The file should only engage the cutter on the
forward stroke. Lift the file off the cutter on the
return stroke.
− Sharpen the shortest cutter first. Then the length
of this shortest cutter becomes the standard for all
other cutters on the saw chain.
006927
− Guide the file as shown in the figure.
− The file can be guided more easily if a file holder
(optional accessory) is employed. The file holder
has markings for the correct sharpening angle of
30 ° (align the markings parallel to the saw chain)
and limits the depth of penetration (to 4/5 of the
file diameter).
