4.7 Fuel Mixture and Refueling
WARNING
■ This brushcutter requires a fuel mixture of gas‐
oline and two-stroke engine oil. Mixed fuel and
gasoline are extremely flammable. If fuel mix‐
ture or gasoline make contact with open fire or
hot objects, they can cause a fire or explo‐
sions. Persons may be seriously or fatally
injured and property may be damaged.
► Protect fuel mixture and gasoline from heat
and fire.
► Do not spill fuel mixture or gasoline.
► If fuel is spilled: Wipe up fuel with a cloth
and do not attempt to start engine until all
parts of the brushcutter are dry.
► Do not smoke.
► Never refuel near a fire.
► Shut off the engine and allow it to cool
down before refueling.
► Start the engine at least 3 meters from the
fueling spot, outdoors only.
■ Inhaling fuel fumes and gasoline fumes can
have toxic effects.
► Avoid inhaling fuel fumes or gasoline
fumes.
► Refuel in a well-ventilated location.
■ The brushcutter becomes hot during opera‐
tion. The fuel expands and excess pressure
can build up in the tank. Fuel can escape as a
spray when the fuel tank cap is opened. The
escaping fuel can ignite. This may result in
serious injury to the user.
► Allow the brushcutter to cool down first and
then open the fuel tank cap carefully.

gasoline will ignite more easily. Persons may
be seriously or fatally injured and property
