6. Cover air cleaner and exhaust outlet tightly with plastic or
other waterproof material to keep out moisture, dirt and
insects.
7. Completely grease and oil unit as outlined in the 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.

Starting After Long Term Storage

Before starting the unit after it has been stored for a long period
of time, perform the following steps.
1. Remove any blocks from under the unit.
2. Install the battery if it was removed.
3. Unplug the exhaust outlet and air cleaner.
4. Fill the fuel tank with fresh gasoline. See engine manual for
recommendations.
5. See engine owner's manual and follow all instructions for
preparing engine after storage.
6. Check crankcase oil level and add proper oil if necessary.
If any condensation has developed during storage, drain
crankcase oil and refill.
7. Inflate tires to proper pressure. Check fluid levels.
8. Start the engine and let it run slowly. DO NOT run at high
speed immediately after starting. Be sure to run engine only
outdoors or in well ventilated area.
