to get the serious personal injury when inhaling

or spilling on your body. Always pay attention

when handling fuel. Always have good ventilation

when handling fuel inside building.

○ Always use branded 89 octane unleaded

gasoline.

○ Do not use a mixture of gasoline and engine

oil as this may lead to starter failure or power

reduction.

Fueling

WARNING

● Always shut oﬀ the engine and let it cool for

a few minutes before refueling.

Do not smoke or bring ﬂ ames or sparks near

the fueling site.

● Slowly open the fuel tank, when ﬁ lling up

with fuel, so that possible over-pressure

disappears.

● Tighten the fuel cap carefully, after fueling.

● Always move the trimmer at least 10 ft (3 m)

from the fueling area before starting.

● Always wash any spilled fuel from clothing

immediately with soap.

● Be sure to check for any fuel leakage after

refueling.

● Before fueling, in order to remove static

electricity from the main body, the fuel

container and the operator, please touch the

ground that is slightly damp.

Cutting

WARNING

● Always wear the proper attire and protective

equipment when operating the unit. (Fig. 12)

● Keep others including children, animals,

bystanders and helpers outside the 15 m

hazard zone. Stop the engine immediately if

you are approached. (Fig. 13)

● When grass or vines wrap around

attachment, stop engine and attachment

and remove them. Continuing operation

with grass or vines wrapped around the

attachment may result in damages such as

early abrasion of the clutch.

Fig. 12 Fig. 13

NOTE

Use in accordance with local laws and

regulations.

Using a semi-auto cutting head

○ Set the engine at high speed when using this

attachment.

○ Cut grass from left to right. The cut grass will

be discharged away from the body, minimizing

transfer to your clothes. (Fig. 14)

○ With nylon cord, use about 3/4” (2 cm) of the end

of the cord to cut grass. Using the full length of

the cord will reduce rotation speed and make

cutting diﬃ cult.

Fig. 14

NOTE

Automatically feeds more nylon cutting line

when it is tapped at low rpm (not greater than

6,000 min

-1

WARNING

● This product is equipped with a line limiter

that will automatically cut any excess cord.

When operating the unit, do not remove the

guard or line limiter.

As the resistance is greater for nylon cords

as opposed to blades, mishandling could

increase engine load and result in damage.

● Do not use with the engine set at low

speeds. If the engine speed is low, grass

may wrap around the attachment, causing

the clutch to slip which could result in clutch

abrasion.

● With nylon cord cutters, always use over

5-7/8” (15 cm) of cord. If the length of

the cord is too short, rotation speed will

increase and may cause damage to the

nylon cord cutter. As the curved drive shaft

tube model in particular is not equipped with

a deceleration mechanism, the possibility

of increased rotation speed for the cutting

attachment is high.

Stopping (Fig. 15)

Decrease engine speed and run at an idle for a few

minutes, then turn oﬀ ignition switch (10).

Fig. 15

English

WARNING

A cutting attachment can injure while it

continues to spin after the engine is stopped

or throttle trigger is released. When the

unit is turned oﬀ , make sure the cutting

attachment has stopped before the unit is

set down.

MAINTENANCE

MAINTENANCE, REPLACEMENT OR REPAIR

OF THE EMISSION CONTROL DEVICES AND

SYSTEMS MAY BE PERFORMED BY ANY NON-

INDIVIDUAL.

Carburetor adjustment (Fig. 16)

Fig. 16

WARNING

● The cutting attachment may be spinning

during carburetor adjustments.

● Never start the engine without the complete

clutch cover and tube assembled! Otherwise

the clutch can come loose and cause

personal injuries.

In the carburetor, fuel is mixed with air. When the

engine is test run at the factory, the carburetor is

basically adjusted. A further adjustment may be

required, according to climate and altitude. The

carburetor has one adjustment possibility:

T = Idle speed adjustment screw.

Idle speed adjustment (T)

Check that the air ﬁ lter is clean. Be sure the cutting

attachment stop turning when the engine idle. When

the idle speed is correct, the cutting attachment

will not rotate. If adjustment is required, close

(clockwise) the T-screw, with the engine running,

until the cutting attachment starts to rotate. Open

(counter-clockwise) the screw until the cutting

attachment stops. You have reached the correct

idle speed when the engine runs smoothly in all

positions well below the rpm when the cutting

attachment starts to rotate.

If the cutting attachment still rotates after idle speed

adjustment, contact Hitachi Authorized Service

Centers.

NOTE

Standard Idle rpm is 2,800 – 3,200 min

–1

WARNING

When the engine is idling the cutting

attachment must under no circumstances

rotate.

Changing the engine oil

Dirty engine oil will considerably reduce the service

life of the engine. Check and change the engine oil

regularly.

CAUTION

● To avoid risk of burn injury, allow the engine

to cool thoroughly before changing the

engine oil.

● To prevent breakdown, ensure that no sand

or dirt gets into the tank while refueling.

When to change the oil: When ﬁ rst using the unit,

after approximately 10 hours of operation or after

1 month, whichever occurs earlier; subsequently,

after every 50 hours of operation or every 6 months,

whichever occurs earlier.

Speciﬁ ed engine oil: Multigrade oil of classiﬁ cation

SAE 10W-30

○ Fill the oil tank with the speciﬁ ed amount of

engine oil.

Too much or too little engine oil may result in

engine breakdown.

○ Engine oil deteriorates naturally even if unused.

Change the engine oil regularly.

Air ﬁ lter (Fig. 18)

Fig. 18

The air ﬁ lter must be cleaned from dust and dirt in

order to avoid:

○ Carburetor malfunctions.

○ Starting problems.

○ Engine power reduction.

○ Unnecessary wear on the engine parts.

○ Abnormal fuel consumption.

Clean the air ﬁ lter daily or more often if working in

exceptionally dusty areas.

Cleaning the air ﬁ lter

Remove the air ﬁ lter cover and the ﬁ lter (14). Rinse

it in gasoline. Check that the ﬁ lter is dry before

reassembly. An air ﬁ lter that has been used for some

time cannot be cleaned completely. Therefore,

it must regularly be replaced with a new one. A

damaged ﬁ lter must always be replaced.

Fuel ﬁ lter (Fig. 19)

Remove the fuel ﬁ lter (15) from the fuel tank, and

replace it if it is dirty.

NOTE

A blocked fuel ﬁ lter (15) can prevent the supply of

fuel and cause a rotation malfunction of the engine.

Fig. 19

Spark plug (Fig. 20)

.024˝

(0.6 mm)

Fig. 20

The spark plug condition is inﬂ uenced by:

○ An incorrect carburetor setting.

○ A dirty air ﬁ lter.

○ Hard running conditions (such as cold weather).

○ Too much engine oil

These factors cause deposits on the spark plug

electrodes, which may result in malfunction and

starting diﬃ culties. If the engine is low on power,

diﬃ cult to start or runs poorly at idling speed, always

check the spark plug ﬁ rst. If the spark plug is dirty,

clean it and check the electrode gap. Readjust if

necessary. The correct gap is .024˝ (0.6 mm). The

spark plug should be replaced after about 100

operation hours or earlier if the electrodes are badly

eroded.

NOTE

In some areas, local law requires using a resistor

spark plug to suppress ignition signals. If this

machine was originally equipped with resistor

spark plug, use same type of spark plug for

replacement.
