ing in e_sential fuel system parts such as the carbu-
retor, fuel filter, fuel hose, or" fuel tank during

empty, mix stabilizer With fresh gasoline in a separate
container and add to the tank.
ALWAYS FOLLOW INSTRUCTIONS ON THE
S_ABILIZER CONTAINER. TH_HE-
ENGINE AT LEAST 10 MINUTES AFTER
STABILIZER IS ADDED TO ALLOW MIXTURE TO
REACH CARBURETOR. STORE UNIT IN A SAFE
