GTORAGE
WARNING
....... it
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 f{)rming
in essential fuel system parts such as the carburetor,
fuel hose or fuel tank during storage. Also, experience
indicates that alcohol blended fuels (called gas )hol 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.
14
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.
t WARN,NG
t
Drain
fuel
into
approved
container
outdoors,
