If the engine has been running, allow it to cool for at least half an hour before cleaning. Clean all exterior surfaces, touch up any damaged paint, and coat other areas that may rust with a light film of oil.
For long term storage, avoid fuel deterioration problems by draining the fuel tank and carburetor.
Select a well-ventilated storage area away from any appliance that operates with a flame, such as a furnace, water heater or clothes dryer.
Avoid any area with a spark producing electric motor or where power tools are operated.
If possible, avoid any area with high humidity. Humidity promotes rust and corrosion.
Position the equipment so that the engine is level. Tilting the engine can cause fuel or oil leakage.
If the engine is equipped with a battery, remove the battery and store it in a cool dry place. Recharge the battery once a month while the engine is in storage. This will help to extend the service life of the battery.
