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.
