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.

12 ENGLISH
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 residual current device
(RCD) protected supply. Use of an RCD 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, EN 166 in Europe, or AS/NZS 1336
in Australia/New Zealand. In Australia/New
Zealand, it is legally required to wear a face
shield to protect your face, too.
It is an employer's responsibility to enforce
the use of appropriate safety protective equip-
ments by the tool operators and by other per-
sons 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.
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.

rear grip with your right hand, no matter you
are right-hander or left-hander. Wrap your
ngers and thumbs around the grips.
6. Hold the tool by insulated gripping surfaces
only, because the saw chain may contact hid-
den wiring. A saw chain contacting a “live” wire
may make exposed metal parts of the extend-
ed-reach pruner “live” and could give the operator
an electric shock.
7. Never attempt to operate the tool with one
hand. Loss of control may result in serious or
fatal injury. To reduce the risk of injury, keep
your hands and feet away from the saw chain.
8. Do not overreach. Keep proper footing and
balance at all times. Watch for hidden obsta-
cles such as tree stumps, roots and ditches
to avoid stumbling. Clear fallen branches and
other objects away.
9. Never work on a ladder or tree to avoid loss of
control.
10. If the tool gets heavy impact or fall, check the
condition before continuing work. If there is
any damage or doubt, ask Makita authorized
service center for the inspection and repair.
11. Do not touch the head of the tool. The head of
the tool becomes hot during operation.
12. Take a rest to prevent loss of control caused
by fatigue. We recommend to take a 10 to
20-minute rest every hour.
13. When you leave the tool, even if it is a short
time, always switch o󰀨 the tool and remove the
battery cartridge. The running and unattended
tool may be used by unauthorized person and
cause serious accident.
14. When operating the tool, do not raise your
right hand above your shoulder height.
15. During operation, never hit the saw chain
against hard obstacles such stones and nails.
Take particular care when cutting branches
next to walls, wire fences or the like.
16. If branches get caught in the tool, always stop
the tool and remove the battery cartridge.
Otherwise unintentional start may cause serious
injury.
17. If the saw chain becomes clogged, always
switch o󰀨 the tool and remove the battery
cartridge before cleaning.
18. Accelerating the tool with the saw chain
blocked increases the load and will damage
the tool.
19. Before cutting limbs, keep an escape area
away from the falling limb. First, clear
obstructs such as limbs and branches from
the work area. Move all tools and goods from
the escape area to another safe place.
20. Before cutting branches and limbs, check
the falling direction of them, considering the
condition of branches and limbs, adjoining
trees, wind direction, etc. Pay full attention to
the falling direction, and the rebound of the
branch, which hit the ground.
21. Never hold the tool at an angle of more than
60°. Otherwise falling objects can hit the oper-
ator and cause serious injury. Never stand
underneath the limb being cut.
22. Pay attention to broken or bent branches. They
may bounce back in cutting, causing unexpected
injury.
23. Before cutting limbs that you intend to cut,
remove branches and leaves around them.
Otherwise the saw chain may be caught by them.
24. To prevent the saw chain from being caught in
the kerf, do not release the lever before pulling
the saw chain out of the kerf.
25. If the saw chain is bound in the kerf, immedi-
ately stop the tool, carefully move the branch
to open the kerf and release the saw chain.
26. Avoid kickback (rotational reactive force
towards the operator). To prevent kickback,
never use the guide bar nose or perform a
penetrating cut. Always beware of the position
of the guide bar nose.
27. Check the chain tension frequently. When
checking or adjusting the chain tension,
switch o󰀨 the tool and remove the battery
cartridge. If the tension is loose, tighten it.

Tips for maintaining maximum
battery life
1. Charge the battery cartridge before completely
discharged. Always stop tool operation and
charge the battery cartridge when you notice
less tool power.
2. Never recharge a fully charged battery car-
tridge. Overcharging shortens the battery
service life.
3. Charge the battery cartridge with room tem-
perature at 10 °C - 40 °C (50 °F - 104 °F). Let
a hot battery cartridge cool down before
charging it.
4. When not using the battery cartridge, remove
it from the tool or the charger.
5. Charge the battery cartridge if you do not use
it for a long period (more than six months).
