Fuel Mixture and Refueling

WARNING

■ This trimmer requires a fuel mixture of gaso‐

line and two-stroke engine oil. Fuel mixture

and gasoline are extremely flammable. If fuel

mixture or gasoline make contact with open

fire or hot objects, they can cause a fire or

explosion. This can result in serious or fatal

injuries and damage to property.

► Protect fuel mixture and gasoline from heat

and fire.

► Do not spill fuel mixture and gasoline.

► If fuel has been spilled: Wipe up the fuel

with a cloth and do not attempt to start the

engine until all parts of the trimmer and the

area around it 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 trimmer becomes hot during operation.

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 can result in

serious injuries.
