S Store in a dry area out of the reach of chil-
dren.
S Ensure the machine is cleaned and that a
complete service is carried out before
long- -term storage.
S The guide bar and chain must always be
covered with a scabbard when the machine
is being transported or in storage in order to
prevent accident contact with the sharp
chain. Even a non- -moving chain can cause
serious cuts to yourself or persons you
bump into with an exposed chain.
CAUTION
: It is important to prevent
gum deposits from forming in essential fuel
system parts such as the carburetor, fuel fil-
ter, fuel hose, or fuel tank during storage. Al-
cohol blended fuels (called gasohol or using
ethanol or methanol) can attract moisture
which leads to fuel mixture separation and
formation of acids during storage. Acidic gas
can damage the engine.
