4. Operating procedures.
Fuel (Fig. 2-1)
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.
Only for the state of California at 50:1.
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 filling 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 (10
ft.) from the fueling area before starting.
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.
