OPERATING PROCEDURES

Fuel (Fig. 11)
WARNING
○ The backpack brush cutter 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 is highly fl ammable and toxic and can result in serious
injury if it is inhaled or comes into contact with your skin. Always
handle fuel with care. 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 start by fi ling 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.
Fueling
