ill, or under the inuence of drugs, alcohol or
medication. A moment of inattention while oper-
ating the machine may result in serious personal
injury.
4. Avoid using the machine in bad weather
conditions especially when there is a risk of
lightning.
5. Follow your national and local regulation for
use of outdoor power machines.
Intended use of machine
This machine is only intended for cutting grass,
weeds, bushes and undergrowth. Never use the
machine for any other purpose such as edging or
hedge cutting. Use for unintended purpose may result
inseriousinjury.
Personal protective equipment
1. Always wear heavy, long pants, sturdy boots,
gloves, and a long-sleeve shirt. Do not wear
loose clothing, jewelry, short pants, sandals,
or go barefoot. Secure hair so it is above
shoulder level.
2. Always wear a helmet where there is a risk of
falling objects.
3. Always wear protective goggles to protect
your eyes from injury when using the machine.
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.
4. Wear ear protection, such as ear muffs.
Exposure to noise can cause hearing loss.
5. Always wear sturdy shoes with a non-slip
sole.Thisprotectsyourfeetagainstinjuriesand
ensures a good footing.
6. Wear a dust mask as necessary.
Preparation before use
1. Before use, always check the machine is safe
for operation:
— Check for fuel leaks.
— Make sure all fasteners are in place and
secure.
— Replace damaged parts.
— Make sure the cutting tool is properly
installed and securely fastened.

13 ENGLISH
— Make sure the cutting tool guard is prop-
erly attached in the position as described
in this manual.
— Check the throttle trigger, lock-off lever
and other control switch for smooth
action and proper function.
— Clean the handles for proper control of
the machine.
— Make sure the handles are installed as
described in this manual.
Failure to follow those instruction may cause
seriousinjury.
2. Use a sharp blade. Discard blades that are
bent, warped, cracked, broken, chipped or
damaged in any way. A dull blade is more likely
to snag and kickback.
3. Always use all required parts for xing the
blade properly.Improperxingpartscancause
thebladetoyoffandseriouslyinjuretheoperator
and/or bystanders.
Refueling
1. Stop the engine before refueling. Keep away
from open ames and sparks. Never smoke
during refueling.Otherwisereand/orexplosion
may result.
2. Refuel outdoors. Refueling in a closed room can
cause explosion of fuel vapor.
3. Avoid contact with fuel or engine oil. Do not
inhale fuel vapor. If fuel or oil spills, wipe it off
of the machine and/or ground immediately. If
fuel spills on your clothes, change it immedi-
ately to prevent it from catching re.
4. After refueling, carefully tighten the fuel tank
cap and check for fuel leak. Move at least 3 m
(10 feet) away from the fueling source and site
before starting engine.
5. Only transport and store fuel in approved con-
tainers. Keep children away from the stored
fuel.
Starting up the brushcutter
1. Keep children, bystanders and pets at least 15
m (50 feet) away, when starting up or using the
machine. Additionally, bystanders should wear
eye protection, as there is still a risk of injury
from thrown objects. Otherwise bystanders'
unexpected action or blade kickback may cause
seriousinjurytotheoperatorand/orbystanders.
2. Start and operate the machine only outdoors
in a well ventilated area.Operationinaconned
or poorly ventilated area can result in death due to
suffocation or carbon monoxide poisoning.
3. Before starting, make sure that the cutting
tool has no contact with hard objects such as
branches, stones etc. as the cutting tool will
revolve when starting.
4. If the cutting tool rotates at idle, adjust the idle
speed so that it stops at idle. Otherwise uninten-
tional contact with moving cutting tool may result
inseriousinjury.
5. Stop the motor immediately if you notice any
trouble.
Transportation
1. Stop the motor during transport. Otherwise
unintentionalstart-upmaycauseinjury.
2. When transporting the machine, always attach
the cover to the cutting blade. Contact with bare
bladesresultsininjury.
3. Ensure safe position of the machine during car
transportation to avoid fuel leakage.
4. Lift the entire machine from the ground when
carrying the machine. Dragging the machine
causes fuel tank damage and fuel leakage, result-
inginre.
Operation
1. Only use the machine in good light and visi-
bility. Use in the dark or poor visibility area may
cause unexpected accident.
2. During the winter season, beware of slippery
or wet areas, ice and snow to avoid slipping.
3. If you are approached, stop the motor.
Otherwise the rotating cutting tool may hit the
bystanderandresultinseriousinjury.
4. Clear the working area before operation.
Remove all objects such as rocks, broken
glass, nails, wire, or string, which can be
thrown or become entangled in the cutting
attachment. Foreign particles may damage the
cutting tool and can cause dangerous kickback.
5. To control the machine steadily, do the follow-
ing during operation:
— Hold the machine with both hands rmly
on your right side.
— Hang the machine on your shoulder(s)
with the shoulder harness.
— Ensure a safe footing. Never work on a
ladder or in a tree.
— Avoid over-reach.
— Keep cutting tool below waist level.
— Keep all parts of your body away from the
rotating cutting tool and hot surface.
Thoseactionreducestheriskofinjury.
6. If weeds or branches get caught between the
cutting tool and guard, always stop the motor
before clearing. Otherwise unintentional blade
rotationmaycauseseriousinjury.
7. Never drop or throw the machine, unless an
emergency. If the machine drops or hits some-
thing, immediately check for fuel leakage,
safety devices and other damages. Operating
anmalfunctionedmachinemaycauseinjuryand/
orre.
8. Inspect the cutting tool frequently, or immedi-
ately after it hits a stone or other hard objects.
If the cutting tool breaks during operation, the
brokenpiecemayyandcauseinjury.
9. Stop the motor when inspecting, cleaning or
replacing the cutting tool. Otherwise the cutting
tool may rotate unexpectedly and result in serious
injury.
10. Maintain proper control until the cutting tool
stops completely, when stopping the motor or
releasing the throttle trigger. A coasting blade
cancauseinjury.

14 ENGLISH
11. Before starting the cutting operation, wait until
the cutting tool attains enough speed for cut-
ting. It reduces the risk of kickback and entangling
weeds.
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. Stop the motor and place it in safe location,
when resting or leaving the machine. It pre-
vents unexpected accident.
14. Do not touch the engine and its mufer or do
not put them onto combustible materials, while
the engine runs or just after stopping it, as
they are hot.Burnand/orremayresult.
Cutting Tools
1. Use a suitable cutting tool for your work.
— Nylon cutting heads (string trimmer heads)
are suitable for trimming lawn grass.
— Metal blades are suitable for cutting weeds,
high grasses, bushes, shrubs, underwood,
thicket, and the like.
Always use the cutting tool guard properly
suited for the cutting tool used.
2. When using a nylon cutting head, use only
exible, nonmetallic line recommended in this
manual. Never use wire or wirerope. They can
breakoffandbecomeadangerousprojectile.
3. Never use metal multi-piece pivoting chains,
ail blades or blades not recommended in this
manual.Otherwiseseriousinjurymayresult.
4. When handling the metal blade, always wear
gloves and put the blade cover on the blade.
The blade can cut bare hands.
5. When using metal blades, avoid “kickback”
and always prepare for an accidental kickback.
See the section Kickback.
Kickback (blade thrust)
Kickback (blade thrust) may occur when the spinning
blade contacts an object that it does not immediately
cut. It can be violent enough to cause the unit and/or
operator to be propelled in any direction, and possibly
lose control of the unit, resulting in serious injury.
Kickback can occur without warning if the blade
snags, stalls or binds and is more likely to occur in
areas where it is difcult to see the material being cut.
Kickback occurs particularly when applying the
blade segment between 12 and 2 o’clock to solids,
bushes and trees with 3 cm or larger diameter.
►Fig.1
To avoid kickback:
1. Apply the segment between 8 and 11 o’clock.
2. Swing the tool evenly in half-circle from right
to left, like using a scythe. This allows the
proper segment of blade to contact plants to be
cut.
3. Never apply the segment between 12 and 2
o’clock.
4. Never apply the segment between 11 and 12
o’clock and between 2 and 5 o’clock, unless
the operator is well trained and experienced
and does it at his/her own risk.
►Fig.2
5. Never use cutting blades close to solids, such
as fences, walls, tree trunks and stones.
6. Never use cutting blades vertically, for such
operations as edging and trimming hedges.
7. Avoid using the tool in areas where it is dif-
cult to see the object being cut.
Vibration
Exposing to excessive vibration injures blood ves-
sels or nervous system of the operator and causes
the following symptoms in the ngers, hands or
wrists: “Falling asleep” (numbness), tingling, pain,
stabbing sensation, alteration of skin color or of
the skin. If any of these symptoms occur, see a
physician.
To reduce the risk of “white nger disease”, keep
your hands warm during operation and well main-
tain the machine and accessories.
Maintenance
1. Have your machine serviced by our authorized
service center using only identical replace-
ment parts. Use only identical spare parts and
accessories supplied by MAKITA. Incorrect
repair and poor maintenance can shorten the life
of the machine and increase the risk of accidents.
2. Never alter or remove any components of the
machine.Itmaycausereand/orseriousinjury.
3. After use, clean the machine and check all
screws and nuts for tightness.
4. Check the condition of the cutting tool, cutting
tool guard and shoulder harness. The cutting
blade must be sharp. Never straighten or weld
damaged cutting tools.
Other instructions
1. Always store the machine in locked rooms and
with an emptied fuel tank.
2. Pay attention to the environment. Avoid unnec-
essary throttle operation for less pollution
and noise emissions. Adjust the carburetor
correctly.
3. Do not operate the engine with faulty exhaust
mufer.
First Aid
1. In case of accident make sure that a rst-aid
box is available in the vicinity of the cutting
operations. Immediately replace any item
taken from the rst aid box.
2. When asking for help, give the following
information:
— Place of accident
— What happened
— Number of injured persons
— Kind of injuries
— Your name

15 ENGLISH
Additional safety instructions
1. To avoid accident, leave more than 15m (50
ft) distance between operators when two or
more operators work in one area. Also, arrange
a person to observe the distance between
operators. If someone or an animal enter the
working area, immediately stop the operation.
2.
Only use the cutting tools that are marked with a speed
equal or higher than the speed marked on the tool.
3. Be sure to remove the cover on the cutting

Using a nylon cutting head
During operation, use the tip of the nylon cutting cord
for cut. As the nylon cutting cord is worn and shortened
with the cutting operation, the operator needs to feed it
manually. To feed the nylon cutting cord, tap the nylon
cutting head on the ground while it rotates around 6,000
min-1.
NOTE: If the nylon cutting cord does not feed out,
rewind it. Refer to the chapter “MAINTENANCE.”
