STORAGE
PLACING IN STORAGE
If your lawn tractor will be stored with gasoline in the fuel tank and car-
buretor, it is important to reduce the hazard of gasoline vapor ignition.
Select a well-ventilated storage area away from any appliance that
operates with a flame, such as a furnace, water heater, or clothes
dryer. Also avoid any area with a spark-producing electric motor, or
where power tools are operated.
If possible, avoid storage areas with high humidity, because that pro-
motes rust and corrosion.
Unless all fuel has been drained from the fuel tank, leave the fuel valve
in the off position to reduce the possibility of fuel leakage.
Park the lawn tractor on a level surface. Tilting can cause fuel or oil
leakage.
With the engine and exhaust system cool, cover the lawn tractor to
keep out dust. A hot engine and exhaust system can ignite or melt
some materials. Do not use sheet plastic as a dust cover. A nonporous
cover will trap moisture around the lawn tractor, promoting rust and
corrosion.
