The hedge trimmer is equipped with a two- stroke engine. 

Always run the engine on fuel, mixed with oil.

 

Provide good ventilation, when fueling or handling 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 (10W/30) or waste oil.

○  Always mix fuel and oil in a separate clean container.

Always start by fi lling 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.

○  Always shut off  the engine before refueling.

○  Slowly open the fuel tank (1), 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.
