Before  fueling,  clean  the  tank  cap  area  carefully,  to  ensure  that 
no dir t falls into the tank. Make sure that the fuel is well mixed by 
shaking the container, before fueling.

Starting

CAUTION

Before star ting, make sure the cutting attachment does not 
touch any thing.

1.  Slide ignition switch (18) to RUN position. (

Fig.

17

)

*  Push priming bulb (19) several times so that fuel 

fl

 ows through 

return pipe. (

Fig.

18

)

2.  Set choke lever (20) to START position (A). (

Fig.

19

)

3.  Pull recoil star ter briskly, taking care to keep the handle in your 

grasp and not allowing it to snap back. (

Fig.

20

)

4.  When you hear the engine want to star t, return choke lever to 

RUN position (B). Then pull recoil star ter briskly again.

NOTE

If engine does not star t, repeat procedures from 2 to 4.

5.  After star ting engine, allow the engine about 2– 3 minutes to 

warm up before subjecting it to any load.

Cutting

 (

Fig.

21,

22

)

○

  When cutting, operate engine at over 6500 min

-1

. Extended 

time of use at low rpm may wear out the clutch prematurely.

○

  Cut grass from right to left.

○

  When working on a slope, the blade should allow the contour 

from top to bottom, with the operator looking down to the left.

○

  Blade thrust may occur when the spinning blade contacts a 

solid object in the critical area.

A dangerous reaction may occur causing the entire unit and 
operator to be thrust violently. This reaction is called blade 
thrust. As a result, the operator may lose control of the unit 
which may cause serious or fatal injur y. Blade thrust is more 
likely to occur in areas where it is di

ffi

  cult to see the material to 

be cut.

○

  The blade turns counter-clockwise, therefore, be advised to 

operate the unit from right to left for e

ffi

  cient  cutting.  Keep 

onlookers out of working area at least 15 m.

WARNING

If  cutting  attachment  should  strike  against  stones  or  other 
debris, stop the engine and make sure that the attachment 
and related par ts are undamaged. When grass or vines wrap 
around attachment, stop engine and attachment and remove 
them.

Stopping

 (

Fig.

23

)

Decrease engine speed and run at an idle for a few minutes, then 
turn o

ff

   ignition switch (18).

WARNING

A cutting attachment can injure while it continues to spin after 
the engine is stopped or power control is released. When the 
unit is turned o

ff

 , make sure the cutting attachment has stopped 

before the unit is set down.

How

to

use

nylon

head

When cutting, operate engine at over 6500 min

-1

. Extended use at 

low rpm may wear out the clutch prematurely.
This  product  is  designed  so  that  it  will  stop  cutting  when  the  nylon 
line becomes 16 cm or longer.

WARNING

A cutting attachment can injure while it continues to spin after the 
engine is stopped or power control is released. When the unit is 
turned o

ff

 , make sure the cutting attachment has stopped before 

the unit is set down.

Set the engine speed as low as possible and tap the Head on the 
ground. (

Fig.

24

) Also, you can extend nylon line with hands but the 

engine must be completely stopped. (

Fig.

25

) 

Adjust nylon line to proper length 11-14 cm before each operation.

MAINTENANCE

MAINTENANCE, REPL ACEMENT OR REPAIR OF THE EMISSION 
CONTROL DEVICES AND SYSTEMS MAY BE PERFORMED 
BY ANY NON-ROAD ENGINE REPAIR ESTABLISHMENT OR 
INDIVIDUAL.

Carburetor

adjustment

 (

Fig.

26

)

WARNING

○

  The cutting attachment may be spinning during carburetor 

adjustments.

○

  Never star t the engine without the complete clutch cover and 

tube assembled! Other wise 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 factor y, the carburetor is basically adjusted. A fur ther 
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. 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 star ts 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 star ts to rotate.
If the cutting attachment still rotates after idle speed adjustment, 
contact your Hitachi dealer.

NOTE

Standard Idle rpm is 2500 – 3000 min

-1

.

WARNING

When the engine is idling the cutting attachment must under no 
circumstances rotate.

Air

 fi 

lter

 (

Fig.

27

)

The air 

fi

 lter must be cleaned from dust and dir t in order to avoid:

○

 Carburetor 

malfunctions

○

 Star ting 

problems

○

  Engine power reduction

○

  Unnecessar y wear on the engine par ts

○

  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 (21). Rinse it in warm soap 

suds. Check that the 

fi

 lter is dr y 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.

28

)

Drain all fuel from fuel tank and pull fuel 

fi

 lter line from tank. Pull 

fi

 lter element out of holder assembly and rinse element in warm 

water with detergent.
Rinse thoroughly until all traces of detergent are eliminated. 
Squeeze, do not wring, away excess water and allow element to air 
dr y.

NOTE

If element is hard due to excessive dir t buildup, replace it.

Spark

plug

 (

Fig.

29

)

The spark plug condition is in

fl

 uenced by:

○

  An incorrect carburetor setting

○

  Wrong fuel mixture (too much oil in the gasoline)

○

  A dir ty air 

fi

 lter

○

  Hard running conditions (such as cold weather)
