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.
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.
7. Power tools can produce electromagnetic
elds (EMF) that are not harmful to the user.
However, users of pacemakers and other similar
medical devices should contact the maker of their
device and/or doctor for advice before operating
this power tool.
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 and clothing away
from moving parts. Loose clothes, jewellery 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.
8. Do not let familiarity gained from frequent use
of tools allow you to become complacent and
ignore tool safety principles. A careless action
can cause severe injury within a fraction of a
second.
9. Always wear protective goggles to protect
your eyes from injury when using power tools.
The goggles must comply with ANSI Z87.1 in
the USA.
It is an employer's responsibility to enforce the
use of appropriate safety protective equipment
by the tool operators and by other persons in
the immediate working area.
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.

4ENGLISH
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 remove the battery pack, if detachable,
from the power tool before making any adjust-
ments, changing accessories, or storing power
tools. Such preventive 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 and accessories. 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 dam-
aged, 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.
8. Keep handles and grasping surfaces dry,
clean and free from oil and grease. Slippery
handles and grasping surfaces do not allow for
safe handling and control of the tool in unexpected
situations.
9. When using the tool, do not wear cloth work
gloves which may be entangled. The entangle-
ment of cloth work gloves in the moving parts may
result in personal injury.
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.
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 con-
tact accidentally occurs, ush with water. If
liquid contacts 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. Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
3. Follow instruction for lubricating and chang-
ing accessories.
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.
General pruning saw safety
warnings
1. Keep all parts of the body away from the saw
chain when the pruning saw is operating.
Before you start the pruning saw, make sure
the saw chain is not contacting anything. A
moment of inattention while operating pruning
saws may cause entanglement of your clothing or
body with the saw chain.
2. Always hold the pruning saw with one hand on
the rear handle and the other hand on the front
handle.
3. Hold the pruning saw by insulated gripping
surfaces only, because the saw chain may con-
tact hidden wiring. Saw chains contacting a "live"
wire may make exposed metal parts of the pruner
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 pruning saw in a tree, on a
ladder, from a rooftop, or any unstable sup-
port. Operation of a pruning saw in this manner
could result in serious personal injury.
6. Always keep proper footing and operate the
pruning saw only when standing on xed,
secure and level surface. Slippery or unstable
surfaces may cause a loss of balance or control of
the pruning saw.
7. When cutting a branch that is under tension,
be alert for spring back. When the tension in the
wood bres is released, the spring loaded branch
may strike the operator and/or throw the pruning
saw out of control.
8. Use extreme caution when cutting brush and
saplings. The slender material may catch the saw
chain and be whipped toward you or pull you o󰀨
balance.

5ENGLISH
9. Carry the pruning saw with the pruning saw
switched o󰀨 and away from your body. When
transporting or storing the pruning saw,
always t the guide bar cover. Proper handling
of the pruning saw will reduce the likelihood of
accidental contact with the moving saw chain.
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 pruning saw for
purposes not intended. For example: do not
use pruning saw for cutting metal, plastic,
masonry or non-wood building materials. Use
of the pruning saw for operations di󰀨erent than
intended could result in a hazardous situation.
12. This pruning saw is not intended for tree fell-
ing. Use of the pruning saw for operations di󰀨er-
ent than intended could result in serious injury to
the operator or bystanders.
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 pruning
saw user, you should take several steps to keep
your cutting jobs free from accident or injury.
Kickback is the result of pruning 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 n-
gers encircling the pruning 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 pruning
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 pruning 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 pruning saw.
Make sure the switch is o󰀨 and the battery
pack is removed.

OPERATION
Lubrication
CAUTION: Do not operate the tool 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.
NOTICE: When the tool 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 mech-
anism. 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 tools 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.

Working with the tool
CAUTION: Keep all parts of the body away
from the saw chain when the tool is operating.
CAUTION: Hold the tool rmly with both
hands when the tool is operating.
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.
Before starting the tool, bring the root of guide bar and
the support part of tool body in contact with the branch
to be cut as shown in the gure. While contacting the
branch with the tool and guide bar, start the tool and
saw the branch by moving the tool down along the
branch.
Fig.24
CAUTION: Before the cutting operation, make
sure that the branch to be cut is in contact with
the root of guide bar and the support part of tool
body. Otherwise, the tool may be pulled toward the
tip of guide bar and the guide bar may wobble, and
may result in an injury.

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)
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.

Fig.26
► 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 80TXL : 0.65 mm (0.025″)
30

Fig.27
— 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 80TXL : 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 80TXL : 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.

15 ENGLISH
— 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.

— The le can be guided more easily if a le holder
(optional accessory) is employed. The le 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
le diameter).

— Remove any projecting material, however small,
with a special at le (optional accessory).
— 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.
Fig.31
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 discharge
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.
