still hot after shutting off the machine.

• Do not refuel while smoking.

• Thoroughly wipe away any spilled fuel after refueling.

• Start the engine at a location at least 3 meters away from the

refueling area or the fuel container. Fuel is highly inﬂammable,

and a ﬁre can lead to death or severe injury.

12. Exhaust Gas Precautions

DANGER

Do not run the engine in a room or in any conﬁned area

where exhaust emissions can accumulate. Doing so can

result in an accumulation of carbon monoxide and other

poisonous gases that can cause death or severe poisoning.

13. Cutting Blade Precautions

DANGER

• Do not approach the running blade or nylon trimmer with your

hand or foot.

• If long grass or any other object becomes entangled in the

cutting blade or nylon trimmer, shut off the engine and wait for

the cutting blade or nylon trimmer to stop completely.

• Wear heavy-duty gloves and use caution when handling the

stopped blade. The cutting blade is very sharp and can cause

death or severe injury.

14. The Hazard Area

WARNING

• Do not operate the device within 15 meters of a child, animal,

or bystander. Consider a 15-meter radius around the device to

be a “hazard area.”

• If someone approaches the hazard area, immediately shut off

the engine. A running machine can eject debris or gravel at a

speed that can cause death or severe injury.

15. Limit your worktime

WARNING

• Do not operate the machine for more than 2 hours a day.

• Rest for 10 to 20 minutes after every 30 to 40 minutes of

operation.

Continuing to operate the brush cutting without a break can result in

excessive fatigue. The resulting loss of attentiveness can lead to an

accident or problems with your ﬁngers or hands. If you experience

any abnormal symptoms such as pain, discomfort, or paralysis of

the ﬁngers or hand, immediately stop operating the machine and

seek medical attention.

16. Avoiding Electric Shock

Ensuring Safe Operation

CAUTION

To ensure safety, strictly observe the following instructions. Failure to

do so can lead to personal injury or severe damage to the machine.

1. Uses of the cutting blade and nylon trimmer

The brushcutter can be used with either the cutting blade

or nylon trimmer.

Blade

The cutting blade can be used to cut various types of

grass.

CULTIVATOR EDGER PRUNING SAW HEDGE TRIMMER BRUSHCUTTER

Blade

• The cutting attachments of the brushcutter rotate

counterclockwise. Cut a 1.5-meter arc from right to left. Within

this arc, maintain the cutting blade at a consistent height above

the ground. Advance slowly and gradually, beginning with the

right foot.

• Cut brush with the arc αon the cutting blade. If the arc βon

the rotating blade hits a solid object, a cutting blade running

at high speed will thrust toward the operator, creating a very

dangerous situation. (Fig.3-5)

11. Abnormal noise and vibration

• If the machine suddenly exhibits abnormal noise or vibration,

immediately shut off the engine.

• Possible causes of sudden noise or vibration include loose

screws and damage to the cutting blade or other components.

Check the entire machine for any sign of a problem.

• After the cause has been found, do not use the machine until

you have completed the repair.

Fuel and Oil

DANGER

• Do not handle fuel near open ﬁre (open ﬂame, lit cigarette,

stove, etc.) or electrical spark (from electrostatic discharge,

welding spark, or switch or battery short-circuit). Doing so can

cause the fuel to ignite, resulting in a ﬁre.

• Do not refuel while the engine is running or while the engine is

still hot after shutting off the machine. Allowing fuel to splash on

a hot engine can result in a ﬁre.

• Refuel the machine outdoors or in a well-ventilated location.

• After refueling, securely close the fuel cap and thoroughly wipe

off any spilled fuel. Spilled fuel can ignite after the machine is

running, leading to a ﬁre.

NOTICE

Refer to the engine instruction manual for more details.

2-stroke engine

Fuel

When fueling a 2-stroke engine, use a fuel-oil mixture of

gasoline and 2-stroke engine oil.

• When mixing gasoline with two-cycle engine oil, use only

gasoline which contains NO ETHANOL or METHANOL (types

of alcohol). Use branded 91 octane or higher unleaded gasoline

known to be of good quality. This will help avoild possible

damage to the engine fuel lines and other engine parts.

• 2-stroke engine oil required

Use high-quality JASO FC class 2-stroke engine oil.

NOTICE

Pour the engine oil into a mixing vessel. Add gasoline

and mix thoroughly.

CAUTION

• Do not mix the engine oil and fuel in the fuel tank of the engine.

• Fuel-oil mixtures degrade over time. We recommend that you

prepare only the amount of the fuel-oil mixture you will use in

the short term. Do not use a fuel-oil mixture that was prepared

more than a week earlier. A degraded fuel-oil mixture can

damage the engine.

• Do not use a fuel-oil mixture containing an incorrect proportion

of engine oil. Doing so can cause an engine malfunction or

engine seizure.

When using a mineral oil:

Mix ratio 25:1

Gasoline litres: 1 2 3 4 5

2 cycle oil mL: 40 80 120 160 200

When using a semi-synthetic mineral oil:

Mix ratio 40:1

Gasoline litres: 1 2 3 4 5

2 cycle oil mL: 25 50 75 100 125

IMPORTANT

Two-stroke fuel may seperate. Shake the fuel container thoroughly

before each use. Stored fuel ages. Do not mix more fuel than you

expect to use within a month.

store the machine as follows:

1. Remove debris from the machine. Check the machine for

damage and loose screws. Correct any problems so that the

machine can be restarted later without a problem.

2. Drain the fuel from the fuel tank. Start the engine and run it

until no fuel remains in the carburetor. (The engine will stop

automatically when no fuel remains.)

3. Allow the engine to cool. Remove the spark plug and squirt a

small amount of fresh engine oil into the spark plug hole. Slowly

pull the recoil starter cord two or three times.

4. Reinstall the spark plug. Slowly pull the recoil starter cord and

release it when you feel resistance. (This closes the intake and

exhaust ports.)

5. Lightly wipe the external surface of the engine with cloth. Then,

store the machine in a dry dust-free location where no open ﬁre

is present.

6. Before storing the machine, clean the cutting blade and check

for any irregularities. Install the blade cover provided as a

standard accessory.

7. Store the drained fuel in a safe container and keep it in a cool,

dry room.

CAUTION

Do not store the machine for a prolonged period with fuel remaining

in the fuel tank. Impurities in the fuel will deteriorate, adversely

affecting the carburetor and fuel ﬁlter and possibly causing an

engine malfunction. Always fully drain the fuel before storing the

machine.
