OPERATING

PROCEDURES

Fuel

(Fig.

7)

WARNING

○

  The chain saw 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 contains highly 

fl

 ammable and it is possible to get the 

serious personal injur y when inhaling or spilling on your body. 
Always pay attention when handling fuel. Always have good 
ventilation when handling fuel inside building.

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 star t by 

fi

 lling half the amount of gasoline, which is to be 

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

fi

 lling the fuel tank.

Fueling

WARNING

(Fig.

○

  Always shut o

ff

  the engine before refueling.

○

  Slowly open the fuel tank (12), when 

fi

 lling up with fuel, so that 

possible overpressure disappears.

○

  Tighten the fuel cap carefully, after fueling.

○

  Always move the unit at least 3 m from the fueling area before 

star ting.

○

  Always  wash  any  spilled  fuel  from  clothing  immediately  with 

soap.

○

  Be sure to check any fuel leaking after refueling.

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.

emergency such as kick-back action. Please check to verify that it 
works properly before use.
Application of brake is made by moving the front guard towards the 
bar. During the chain brake operation, even if the throttle lever is 
pulled, the engine speed does not increase and the chain does not 
turn. To release the brake, pull up the chain brake lever.
