Lubrication section.
8. Clean up unit and apply paint or rust preventative to any
areas where paint is chipped or damaged.
9. Be sure the battery is filled to the proper level with water
and is fully charged. Battery life will be increased if it is
removed, put in a cool, dry place and fully charged about
once a month. If battery is left in unit, disconnect the
negative cable.
10. Drain fuel system completely or add a gasoline stabilizer
to the fuel system. If you have chosen to use a fuel
stabilizer and have not drained the fuel system, follow
all safety instructions and storage precautions in this
manual to prevent the possibility of fire from the ignition
of gasoline fumes. Remember, gasoline fumes can travel
to distant sources of ignition and ignite, causing risk of
explosion and fire.
NOTE: Gasoline, if permitted to stand unused for
extended periods (30 days or more), may develop
gummy deposits which can adversely affect the engine
carburetor and cause engine malfunction. To avoid this
condition, add a gasoline stabilizer to the fuel tank and
run the engine a few minutes, or drain all fuel from the
unit before placing it in storage.

period of time, perform the following steps.
