OPERATING PROCEDURES

Fuel (Fig. 1)

WARNING

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.

Fuel

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.
