OPERATING

PROCEDURES

Fuel

 (

Fig.

)

WARNING

The unit is equipped with a two-stroke engine. Always run the 
engine on fuel, which is mixed with oil.

Provide good ventilation, when fueling or handling fuel.

Fuel

○

  Always use branded 89 octane unleaded gasoline.

○

  Use genuine two-cycle oil or use a mix between 25:1 to 50:1, 

please consult the oil bottle for the ratio or Hitachi dealer.

○

  If genuine oil is not available, use an anti-oxidant added quality 

oil expressly labeled for air-cooled 2-cycle engine use (JASO 
FC GRADE OIL or ISO EGC GRADE). Do not use BIA or TCW 
(2-stroke water-cooling type) mixed oil.

○

  Never use multi-grade oil (10 W/30) or waste oil. 

○

  Always mix fuel and oil in a separate clean container.

Always start by 

fi

 ling half the amount of fuel, which is to be used. Then 

add the whole amount of oil. Mix (shake) the fuel mixture. Add the 
remaining amount of fuel.
Mix (shake) the fuel-mix thoroughly before 

fi

 lling the fuel tank.

Fueling

WARNING

○

  Always shut o

ff

  the engine before refueling.

○

  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 unit at least 3 m from the fueling area before 

starting.

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

MAINTENANCE

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

Carburetor

adjustment

 (

)

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. 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 your Hitachi dealer.

NOTE

○

  Standard Idle rpm is 2500–3000 rpm.

○

  Some models sold areas with strict exhaust emission regulation 

do not have high and low speed carburetor adjustments. Such 
adjustments may allow the engine to be operated outside of their 
emission compliance limits. For these models, the only carburetor 
adjustment is idle speed.

For models that equipped with low and high speed adjustments; 
carburetors are preset at the factory. Minor adjustments may optimize 
performance based on climate, altitude, etc. Never turn the adjustment 
screws in increments greater than 90 degrees, as engine damage can 
result from incorrect adjustment, If you are not familiar with type of 
adjustment-assistance Hitachi dealer.

WARNING

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