4.7 Fuel Mixture and Refueling
WARNING
￭ This trimmer requires a fuel mixture of gasoline 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.
► Allow the trimmer to cool down first and then open the
tank cap carefully.
￭ Clothing that has been in contact with fuel or gasoline is
more easily flammable. This can result in serious or fatal
injuries and damage to property.
► If your clothing comes into contact with fuel or gasoline:
Change your clothing.
￭ Fuel mix, gasoline and two-stroke engine oil can harm the
environment.
► Do not spill fuel, gasoline or two-stroke engine oil.
► Dispose of fuel mix, gasoline and two-stroke engine oil
in accordance with local regulations and environmental
requirements.
￭ Fuel, gasoline or two-stroke engine oil can cause irritation
if they come into direct contact with the skin or eyes.
► Avoid contact with fuel, gasoline and two-stroke engine
oil.
► In case of contact with the skin: Wash affected areas
with plenty of water and soap.
