starting.
– The engine is to be switched off immediately in case of any engine problems.
– Should the cutting tool hit stones or other hard objects, immediately switch off
the engine and inspect the cutting tool.
– Inspect the cutting tool at short regular intervals for damage (detection of
hairline cracks by means of tapping-noise test).
– If the equipment gets heavy impact or fall, check the condition before
continuing work. Check the fuel system for fuel leakage and the controls
and safety devices for malfunction. If there is any damage or doubt, ask our
authorized service center for the inspection and repair.
– Operate the equipment only with the shoulder harness attached which is
to be suitably adjusted before putting the brushcutter into operation. It is
essential to adjust the shoulder harness according to the user size to prevent
fatigue occurring during use. Never hold the cutter with one hand during use.
– During operation always hold the brushcutter with both hands.
Always ensure a safe footing.
– Operate the equipment in such a manner as to avoid inhalation of the exhaust
gases. Never run the engine in enclosed rooms (risk of gas poisoning).
Carbon monoxide is an odorless gas.
– Switch off the engine when resting and when leaving the equipment
unattended, and place it in a safe location to prevent danger to others or
damage to the machine.
– Never put the hot brushcutter onto dry grass or onto any combustible
materials.
– Always install the approved cutting tool guard onto the equipment before
starting the engine.
Otherwise contact with the cutting tool may cause serious injury.
– All protective installations and guards supplied with the machine must be
used during operation.
– Never operate the engine with faulty exhaust muffler.
– Shut off the engine during transport.
– When transporting the equipment, always attach the cover to the cutting
blade.
– Ensure safe position of the equipment during car transportation to avoid fuel
leakage.
– When transporting, ensure that the fuel tank is completely empty.
– When unloading the equipment from the truck, never drop the Engine to the
ground or this may severely damage the fuel tank.
– Except in case of emergency, never drop or cast the equipment to the ground

• Transport
• Refuelling
• Maintenance
• Tool replacement
Refueling
– Shut off the engine during refueling, keep away from open flames and do not
smoke.
– Avoid skin contact with mineral oil products. Do not inhale fuel vapor. Always
wear protective gloves during refueling. Change and clean protective clothing
at regular intervals.
– Take care not to spill either fuel or oil in order to prevent soil contamination
(environmental protection). Clean the brushcutter immediately after fuel has
been spilt.
– Avoid any fuel contact with your clothing. Change your clothing instantly if
fuel has been spilt on it (to prevent clothing catching fire).
– Inspect the fuel cap at regular intervals making sure that it can be securely
fastened and does not leak.
– Carefully tighten the fuel tank cap. Change location to start the engine (at
least 3 meters away from the place of refueling).
– Never refuel in closed rooms. Fuel vapors accumulate at ground lever (risk of

Method of operation
– Only use 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 waist height.
– Never stand on a ladder.
– Never climb up into trees to perform cutting operation.
– Never work on unstable surfaces.
– Remove sand, stones, nails etc. found within the working range.
Foreign particles may damage the cutting tool and can cause dangerous
kick-backs.
– Before commencing cutting, the cutting tool must have reached full working
speed.
– When using metal blades, swing the tool evenly in half-circle from right to left,
like using a scythe.
If grass or branches get caught between the cutting tool and guard, always
stop the engine before cleaning. Otherwise unintentional blade rotation may
cause serious injury.
– Take a rest to prevent loss of control caused by fatigue. We recommend to
take a 10 to 20-minute rest every hour.
Cutting Tools
– Use an applicable cutting tool for the job in hand.
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.
Never use other blades including metal multi-piece pivoting chains and flail
blades. Otherwise serious injury may result.
– When using metal blades, avoid “kickback” and always prepare for an
accidental kickback. See the section “Kickback” and “Kickback prevention.”
Kickback (blade thrust)
– Kickback (blade thrust) is a sudden reaction to a caught or bound cutting
blade. Once it occurs, the equipment is thrown sideway or toward the
operator at great force and it may cause serious injury.
– 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.
– To avoid kickback:
Apply the segment between 8 and 11 o’clock;•
Never apply the segment between 12 and 2 o’clock;•
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;
Never use cutting blades close to solids, such as fences, walls, tree trunks •
and stones;
Never use cutting blades vertically, for such operations as edging and •
trimming hedges.
Vibration
– People 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 color
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.
Maintenance instructions
– Have your equipment serviced by our authorized service center, always using
only genuine replacement parts. Incorrect repair and poor maintenance can
shorten the life of the equipment and increase the risk of accidents.
– The condition of the cutter, in particular of the cutting tool of the protective
devices and also of the shoulder harness must be checked before
commencing work. Particular attention is to be paid to the cutting blades
which must be correctly sharpened.
– Turn off the engine and remove spark plug connector when replacing or
sharpening cutting tools, and also when cleaning the cutter or cutting tool.

BEFORE START OF OPERATION
Inspection and refill of engine oil
– Perform the following procedure, with the engine cooled down.
– Set the engine level, remove oil cap (Fig. 1), and check to see whether or not there is oil in the range between the upper limit and lower limit
marks of the oil pipe (Fig. 2).
– Top up with oil to upper limit mark if oil is insufficient (oil level is close to lower limit mark) (Fig. 3).
– The area surrounding the external marks is transparent, so the amount of oil inside can be checked without having to remove the oil cap.
However, if oil pipe becomes extremely dirty, visibility may be lost, and oil level will have to be checked against stepped section on inside of
oil pipe.
– For reference, the oil refill time is about 10h (10 times or 10 tanks of oil refill).
If the oil changes in color or mixes with dirt, replace it with new one. (For the interval and method of replacement, refer to P 19)
Recommended oil: SAE 10W-30 oil of API Classification, Class SF or higher (4-stroke engine for automobile)
Oil volume: Approx. 0.08L
Note: If the engine is not kept upright, oil may go into around the engine, and may be refilled excessively.
If the oil is filled above the limit, the oil may be contaminated or may catch fire with white smoke.
Point 1 in Replacement of oil: “Oil gauge”
– Remove dust or dirt near the oil refill port, and detach the oil gauge.
– Keep the detached oil gauge free of sand or dust. Otherwise, any sand or dust adhering to the oil gauge may cause irregular oil
circulation or wear on the engine parts, which will result in troubles.

(2) Fill with oil to upper limit mark. (see Fig. 3)
Use oil bottle when filling.
(3) Securely tighten the oil cap. Insufficient tightening may cause oil leakage.
13
Note
● Do not replace oil with the engine in a tilted position.
● Filling with oil while engine is tilted leads to overfilling which causes oil contamination and/or white smoke.
Point 2 in Replacement of oil: “If oil spills out”
– If oil spills out between the fuel tank and engine main unit, the oil is sucked into through the cooling air intake port, which will
contaminate the engine. Be sure to wipe out spilt oil before start of operation.
REFUELING
Handling of fuel
It is necessary to handle fuel with utmost care. Fuel may contain substances similar to solvents. Refueling must be performed in a sufficiently
ventilated room or in the open air. Never inhale fuel vapor, and keep fuel away from you. If you touch fuel repeatedly or for a long time, the
skin becomes dry, which may cause skin disease or allergy. If fuel enters into the eye, clean the eye with fresh water. If your eye remains still
irritated, consult your doctor.
Storage period of fuel
Fuel should be used up within a period of 4 weeks, even if it is kept in a special container in a well-ventilated shade.
If a special container is not used or if the container is not covered, fuel may deteriorate in one day.
STORAGE OF MACHINE AND REFILL TANK
– Keep the machine and tank at a cool place free from direct sunshine.
– Never keep the fuel in the cabin or trunk.
Fuel
The engine is a four-stroke engine. Be sure to use an automobile gasoline (regular gasoline or premium gasoline).
Points for fuel
– Never use a gasoline mixture which contains engine oil. Otherwise, it will cause excessive carbon accumulation or mechanical troubles.
– Use of deteriorated oil will cause irregular startup.
Refueling
WARNING: INFLAMMABLES STRICTLY PROHIBITED
Gasoline used: Automobile gasoline (unleaded gasoline)
– Loosen the tank cap a little so that there will be no difference in atmospheric
pressure.
– Detach the tank cap, and refuel, discharging air by tilting the fuel tank so
that the refuel port will be oriented upward. (Never refill fuel full to the oil refill
port.)
– Wipe well the periphery of the tank cap to prevent foreign matter from
entering into the fuel tank.
– After refueling, securely tighten the tank cap.
● If there is any flaw or damage on the tank cap, replace it.
● The tank cap is consumable, and therefore should be renewed every two to
three years.
