OPERATING PROCEDURES

Fuel (Fig. 19)

WARNING

○ The trimmer 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 start by filing 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 filling the fuel tank.

Fueling

WARNING

○ Always shut off the engine before refueling.

○ Slowly open the fuel tank, when filling up with fuel, so that possible over-pressure disappears.

○ Tighten the fuel cap carefully, after fueling.

○ Always move the trimmer at least 3 m from the fueling area before starting.

○ Always wash any spilled fuel from clothing immediately with soap. ○ Be sure to check for any fuel leakage after refueling.

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.
