SAFETY PRECAUTIONS
General precautions
Proper use: These brushhcutters are provided with the appropri-
ate and approved cutting tools for the respective applications as
described on page 7. A brushcutter may be operated only by one
person, and only out of doors!
Improper use: The use of cutting tools or blades not approved for
this brushcutter is forbidden and may cause damage or injury!
Impermissible users:
Persons who are unfamiliar with this Instruction Manual, minors,
and persons under the inßuence of alcohol, drugs or medication
must not operate this tool.
To ensure correct operation, the user has to read this instruc-
tion manual to make himself familiar with the handling of the
brushcutter. InsufÞciently informed users will risk danger to
themselves as well as others due to improper handling (1).
- It is recommended only to lend the brushcutter to people who
have experience with brushcutters. When lending the brush-
cutter to someone else, give him this Instruction Manual as
well.
- First-time users should ask their dealer for basic instructions
so that they can familiarize themselves with the basic handling
of gasoline-powered brushcutting.
- Children and persons under the age of 18 must not be allo-
wed to operate the brushcutter. Exceptions may be made for
persons over 16 for training purposes under the supervision
of a qualiÞed trainer.
- Always use brushcutters with the utmost care and attention.
- Operate the brushcutter only if you are in good physical con-
dition. Perform all work calmly and carefully. The user must
accept liability for others.
- Never use the brushcutter after consumption of alcohol,
drugs or medication (2).
Personal protective equipment
- The clothing worn should be functional and appropriate, i.e.
it should be tight-Þtting but not cause hindrance. Do not wear
either jewellery or clothing which could become entangled with
bushes or shrubs. Secure hair so it is above shoulder level.
- In order to avoid head-, eye-, hand- or foot injuries as
well as to protect your hearing, the following protective
equipment and protective clothing must be used during
operation of the brushcutter:
- It is recommended to wear a protective helmet; it is imperative
when working in forests. The protective helmet (1) should be
checked at regular intervals for damage and must be replaced
after 5 years at the latest. Use only approved protective hel-
mets.
- The face shield (2) of the protective helmut protects against
ßyingsawdust,wood chips or stone chippings.Duringoperation
of the brushcutter always wear goggles or a visor to prevent
eye injuries.
- Wear adequate noise protection equipment to avoid hearing
impairement ( ear muffs (3), ear plugs etc.). Octave brand
analysis upon request.
- The forestry safety jacket (4) is equipped with special red
coloured shoulder parts. The arms and neck should always be
protected by clothing.

Handling fuels / Refuelling
- Stop the engine before refuelling (11).
- Keep away from open ßame or sparks and do not smoke while
refuelling or mixing fuel (5).
- Let the engine cool down before refuelling.
- Fuel may contain substances similar to solvents. Eyes and skin
should not come in contact with mineral oil products. Always
wear protective gloves when refuelling. Frequently clean and
change protective clothes. Do not breathe in fuel vapors. In-
halation of fuel vapours can be hazardous to your health.
- Before refuelling the brushcutter make sure it is in a stabile
position.
- Do not spill fuel or oil. When you have spilt fuel or oil immedi-
ately clean the brushcutter. Fuel should not come in contact
with clothes. If your clothes come in contact with fuel, change
them at once.
- Ensure that no fuel or chain oil oozes into the soil (environ-
mental protection). Use an appropriate base.
- Refuelling is not allowed in closed rooms. Fuel vapors will
accumulate near the ßoor (explosion hazard).
- Carefully tighten the locking screw of the fuel tank and inspect
the fuel cap at regular intervals.
- Change the place before starting the engine (at least 3 m from
the place of refuelling) (6).
- Fuel cannot be stored for an unlimited period of time. Buy
only as much as will be consumed in the near future.
- Use only approved and marked containers for the transport
and storage of fuel. Ensure children have no access to fuel.
Putting into operation
- Do not work alone. Another person must be nearby in case
of emergencies (within shouting distance).
- Children and other persons must remain more than 15 meters
(16 1/2 yards) from the working area. Keep an eye out for
animals as well (7).
- Before use always check that the brushcutter is safe for
operation:
Make sure the cutting tool is securely installed. The throttle
must automatically return to the off position when released,
and the throttle lever lock must work properly. The cutting tool
must not turn during idling. The handles should be clean and
dry. The on/off switch must function properly. The guard must
be undamaged and securely installed in the correct position.
Otherwise you are in danger of injury!
- Start the brushcutter only in accordance with the instructions. Do
not use any other methods for starting the engine (8)!
- Use this brushcutter and its cutting tools only for the uses
they are intended for as speciÞed in the documentation.
- Start the brushcutter only after complete assembly and
inspection. Operation of the device is only permitted
after all the appropriate accessories are attached!
- The cutting tool must be equipped with its appropriate
guard. Never run the cutter without this guard!
- The cutting tool must not turn during idling. If necessary ad-just
the idling speed.
- Before starting, make sure that the cutting tool has no contact
with hard objects such as branches, stones etc.
- The engine must be switched off immediately if there are
any noticeable changes in the behaviour of the equipment.
- Should the cutting tool hit stones or other hard objects, imme-
diately switch off the engine and inspect the cutting tool.
- Inspect the cutting tool at freqvent intervals for damage (de-
tect hairline cracks by means of tapping - noise test). Hairline
cracks can occur in the region of the base of the teeth (9) after
long use. Damaged cutting tools and cutting tools with
hairline cracks must not be used any longer under any
circumstances.

- Operate the brushcutter only with the shoulder strap attached,
which is to be suitably adjusted before putting the brushcut-
ter into operation. It is essential to adjust the shoulder strap
according to the user’s size to prevent fatigue during use.
Never hold the cutter with one hand during use.
- When working with the brushcutter always hold it with both
hands (10). Keep proper footing and balance at all times.
- Operate the brushcutter in such a manner as to avoid
inhalation of the exhaust gases. Do not start or operate the
brushcutter in closed rooms (risk of gas poisoning). Carbon
monoxide is an odorless gas. Work only in well-ventilated
places.
- When taking a break or leaving the brushcutter unattended,
turn off the engine (11) and set the brushcutter down in such
a way that there is no risk of injury to yourself or others.
- Never put the hot brushcutter onto dry grass or onto any com-
bustible materials.
- Shut off the engine during transport or when moving on to a
new location (11).
- Never operate the engine with a faulty exhaust mufßer.
Kickback
When operating the brushcutter, uncontrolled kickback may
occur. This is especially likely when using the 12-2 o´clock blade
area (12).
Never apply this segment of the brushcutter to solids, such as bus-
hes and trees, etc., having a diameter in excess of 2 cm (3/4").
If you do this, the brushcutter will be thrown to one side at high
speed and with great force. High risk of injury!
Never attempt to cut with the 12-2 o´clock blade area (Þgure
12)!
Kickback prevention (13):
-To avoid kickbacks, observe the following:
- Always watch what you´re doing! Be careful when continuing
cuts started previously.
- The cutting tool must be turning at full speed before starting
cuts.
- Kickback is especially likely in the blade area between 12 and
2 o´clock, especially when using metal cutting tools.
- Cutting operations within a blade segment between 11 and 12
o’clock, and between 2 and 5 o’clock, must only be performed
by trained and experienced operators, and then only at their
own risk.
- Easy cutting with almost no kickback is possible within a
blade segment between 8 and 11 o’clock.

Working behavior / Method of working
- Use the brushcutter only in good light and visibility. During
the winter season beware of slippery or wet areas, ice and
snow (risk of slipping). Always ensure a safe footing.
- Never cut above your shoulder height.
- Never stand on a ladder and run the brushcutter.
- Never climb up into trees to perform cutting operations with
the brushcutter.
- Never work on unstable surfaces.
- Clearthe working area ofany foreign objects suchas stones.
Foreignparticles can rebound (dangerofinjury,14), damage
the cutting tool and cause dangerous kickbacks.
- Before commencing cutting, the cutting tool must have
reached full working speed.
Applications for cutting tools
Employ only the correct cutting tool for the job in hand (15)!
2-line trimmer head:
Exclusively for cutting along walls, fences, grass edges, trees,
posts etc. (supplementing the lawn mower).
8-tooth eddy blade, 4-tooth star blade and steel bush
cutter:
For cutting thicker materials like weeds, tall grass, bushes,
shrubs, mixed growth, thickets, etc. with stems up to 2 cm (3/4")
thick. Perform this cutting work by swinging the brushcutter
evenly in half-circles from left to right (similar to a scythe).
Transport
- When transporting the equipment or moving to another
working location, the brushcutter must be switched off in
order to avoid unintentionally starting the cutting tool.
- Never carry and transport the brushcutter when the cutting
tool is in operation!
- The tool protection included with the equipment must
always be used if the brushcutter is transported over longer
distances.
- Ensure that the brushcutter is safely secured so that no fuel
can run out before transporting it in a vehicle.
- Before shipping the brushcutter, completely empty the fuel
tank.

Storage
- The brushcutter must be safely stored in a dry room. Use the
tool protection for metal cutting tools. Keep the brushcutter out
of reach of children.
- If the brushcutter is stored for a long period of time, it should be
givenathorough maintenance check and acompleteinspection
at an authorized MAKITA service centre.
- If the brushcutter is stored for a long period of time, the fuel
tank should be completely emptied and the carburetor run
dry. Fuels may only be stored for a limited period of time and
could cause deposits to form in the tank or in the carburetor.
- Fuel remains in reserve canisters should be used for other
engines or disposed of.
Maintenance
- The condition of the cutter, in particular of the cutting tool, the
protectivedevices and also theshoulderstrap must be checked
before commencing work. Particular attention must be paid to
the cutting blades, which must be correctly sharpened.
CAUTION: Metal cutting tools must be sharpened only at an
authorized service centre!
A tool which has been improperly sharpened can cause
unbalance and thus considerable danger of injury. Apart
from this, the equipment may be damaged due to
vibrations.
- When changing the cutting tool, cleaning the brushcutter and
the cutting tool etc., it is essential to switch off the engine
and pull the spark plug cap.
- Replace cracked, bent, warped, damaged or dull cutting
tools immediately. Never straighten or weld damaged cutting
tools.
- Operate the brushcutter with as little noise and pollution as
possible. In particular check the correct setting of the carbu-
retor.
- Clean the brushcutter at regular intervals and check that all
screws and nuts are well tightened.
- Never service or store the brushcutter near open ßames
(17)!
- Always store the brushcutter in a locked storage area, with
the fuel tank completely empty and the carburetor run dry.
Observe the accident pre- vention instructions issued by the
relevant trade associations and insurance companies. Do
not make any modiÞcations to the brushcutter - you will only
be putting your own safety at risk!
The performance of maintenance or repair work by the user is
limited to those activities described in this instruction manual. All
other work must be done by the MAKITA customer service (18).
Use only original MAKITA spares and accessories.
The use of non-MAKITA spares, accessories, or cutting tools
increases the risk of accident. MAKITA will not accept any
liabilityforaccidents or damage causedbythe use of non-approved
cutting tools and Þxing devices of cutting tools, or accessories.

Fuel mixture AVOID SKIN AND EYE CONTACT!
Utmost care is required when handling fuel. Fuel may contain
substances similar to solvents. Refuel either in a well venti-
lated room or outdoors. Do not inhale fuel vapors, and avoid
any contact of fuel or oil with your skin. Mineral oil products
degrease your skin. If your skin comes in contact with these
substances repeatedly and for an extended period of time, it
will desiccate. Various skin deseases may result. In addition,
allergic reactions are known to occur. Eyes can be irritated by
contact with oil. If oil comes into your eyes, immediately wash
them with clear water.
If your eyes are still irritated, see a doctor immediately!
The Storage of Fuel
Fuels have a limited storage life. Fuel and fuel mixtures age
through evaporation, especially at high temperatures.Aged fuel
and fuel mixtures can cause starting problems and damage the
engine.Purchaseonlythatamountoffuel,whichwillbeconsumed
over the next few months. At high temperatures, once fuel has
been mixed it should be used up in 6-8 weeks.
Store fuel only in proper containers, in dry, cool, secure
locations!
- Thoroughly clean around the tank cap (B/1) so that no dirt
can enter the fuel tank.
- Unscrewthetank cap (B/2) andcarefullyÞllin the fuel mixture
up to the lower edge of the Þller neck. Fill the tank carefully,
making sure not to spill any fuel.
- Tightly screw on the plug.
Clean screw plug and tank after refuelling.
FOLLOW THE SAFETY PRECAUTIONS!
Be careful and cautious when handling fuels.
The engine must be switched off!
Refuelling
Thistoolispowered by a high-performance air-cooledtwo-stroke
engine. It runs on a mixture of gasoline and two-stroke engine
oil.
The engine is designed for unleaded regular gasoline with a
min. octane value of 91 ROZ. In case no such fuel is available,
you can use fuel with a higher octane value. This will not affect
the engine.
In order to obtain an optimum engine output and to protect
your health and the environment use unleaded fuel only.
To lubricate the engine, use a synthetic oil for two-stroke air-
cooled engines (quality grade JASO FC or ISO EGD), which
has to be added to the fuel. The engine has been designed for
use of MAKITA high-performance two-stroke engine oil and a
mixture ratio of only 50:1 to protect the environment. In addi-
tion, a long service life and reliable operation with a minimum
emission of exhaust gases are ensured.
MAKITA high-performance two-stroke engine oil is available in
the following sizes to suit your individual requirements:
1 l order number 980 008 607
100 ml order number 980 008 606
In case MAKITA high-performance two-stroke engine oil is not
available, it is urgently recommended to use a mixture ratio of
50:1 with other two-stroke engine oils, as otherwise optimum
operation of the engine cannot be guaranteed.
Caution: Do not use ready-mixed fuel from petrol
stations.
The correct mixture ratio:
50:1 whenusingMAKITA high-performance two-stroke engine
oil, i. e. mix 50 parts gasoline with 1 part oil.
50:1 when using other synthetic two-stroke engine oils
(quality grade JASO FC or ISO EGD), i. e. mix 50 parts
gasoline with 1 part oil.
Note:
When preparing the fuel mixture, always Þrst mix the entire
oil quantity with half of the gasoline, and then add the rest of
the gasoline. Shake the mixture well before putting in the fuel
tank.
It is not wise to add more oil to the mixture than speciÞed,
even if this may seem safer for the engine. More oil only leads
to increased combustion residues, which not only pollute the
environment, but are also bad for the cylinder exhaust channel
and the mufßer. Furthermore fuel consumption will increase and
performance will fall.

Trouble shooting
Replacing the suction head
The felt Þlter (G/5) of the suction head is used to Þlter the fuel
taken in by the carburetor.
A periodical visual inspection of the felt Þlter should be conduc-
ted. For this purpose open the tank cap, and use a wire hook
to pull out the suction head through the tank opening. If the
Þlter has hardened or is dirty or clogged, replace it.
InsufÞcient fuel supply can result in the admissible maximum
speed being exceeded. It is therefore important to replace the
felt Þlter at least every three months to ensure a good fuel supply
to the carburetor.
