other sources of ignition such as areas with a spark-
producing electric motor or where power tools are
operated.
• Do not store the generator, gasoline near furnaces,
water heaters, or any other appliances that produce
heat or have automatic ignitions.
• With the engine and exhaust system cool and all
surfaces dry, cover the generator to keep out dust. Do
not use a plastic sheet as a dust cover. Non-porous
materials trap moisture and promote rust and corrosion.
LONG TERM STORAGE
Even properly stabilized fuel can leave residue and cause
corrosion if left long term. If storing the generator for over
six months, drain the fuel tank.
DRAINING THE FUEL TANK
If storing the generator for longer than six months, drain
the fuel tank to prevent fuel separation, deterioration, and
deposits in the fuel system.
