¡STORAGE
A
WARNING
Never store engine with fuel in tank
indoors
or in poorly ventilated
enclosures, where fumes may reach an
open flame, spark or pilot light such
as on a furnace, water heater, clothes
dryer, etc.
It is important to prevent gum deposits from forming
in essential fuel system parts such as the carburetor,
fuel hose or fuel tank during storage. Also, expe rience
indicates that alcohol blended fuels (called gas jhol or
using ethanol or methanol) can attract moisture which
leads to separation and formation of acids during
storage. Acidic gas can damage the fuel syster i of an
engine while in storage.
To avoid engine problems, the fuel system should be
emptied before storage of 30 days or longer. Follow
these instructions.
1. Run engine until fuel tank is empty and engine
stops due to lack of fuel.
2. Disconnect fuel line at carburetor or fuel tank. Be
careful not to damage fuel line, fittings or fuel tank.
Drain any remaining fuel from the system.
A
I WARNING \
Drain fuel into approved container
outdoors, away from open flame.
