Starting - Husqvarna YTH180 Owner's Manual

WARNING: Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or methanol) can
attract moisture which leads to separation and formation of
acids during storage. Acidic gas can damage the fuel
system of an engine while in storage. To avoid engine
problems, the fuel system should be emptied before stor-
age of 30 days or longer. Drain the gas tank, start the
engine and let it run until the fuel lines and carburetor are
empty. Use fresh fuel next season. See Storage Instruc-
tions for additional information.

CAUTION: Fill to bottom of gas tank

spilled oil or fuel. Do not store, spill or
use gasoline near an open flame.
