Starting And Stopping The Engine - Stihl MS 400 C-M Instruction Manual

English
WARNING
■ 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.
► Turn the fuel tank cap about 1/8 of a turn
counterclockwise.
If the fuel tank is under pressure, you will hear
pressure being released.
► When the tank is no longer under pressure:
Turn the tank cap counterclockwise until the
marks on the cap and fuel tank are in align‐
ment.
► Remove the fuel tank cap.
NOTICE
■ Bright light, sunlight and extreme tempera‐
tures can cause the fuel mix to separate much
faster. The saw can be damaged if it is used
with a fuel mix that has become separated.
► Thoroughly mix the fuel.
► Do not use fuel mix that has been stored for
more than 30 days.
► Fill the tank to within no more than 15 mm
of the brim, taking care not to spill any fuel.
► If the grip on the fuel tank cap has dropped
into the closed position: Raise the grip until it
is vertical.
