4.7 Fuel Mixture and Refueling
WARNING
■ This chainsaw 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 saw 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 chainsaw becomes hot during operation,
or in a very hot environment. Depending on
the type of fuel, altitude, ambient temperature
and the temperature of the saw, the fuel
expands and can cause a pressure build-up in
the tank. Fuel may escape as a spray and
ignite when the fuel tank cap is opened. This
can result in serious injuries and damage to
property.
► Allow the saw to cool down before opening
the tank cap.
► Open the tank cap slowly in stages.
■ 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 require‐
ments.
