Maintenance and Storage

Disengage drives, lower implement, set parking brake, stop engine and remove key or disconnect spark plug wire. Wait for all movement to stop before adjusting, cleaning or repairing.

Keep engine and engine area free from accumulation of grass, leaves, excessive grease or oil, and other debris which can accumulate in these areas. These materials can become combustible and may result in a fire.

Let engine cool before storing and Do Not store near flame or any enclosed area where open pilot lights or heat appliances are present.

Store mower in a well ventilated outdoor shelter, building, or trailer.

Close fuel valve when mower is not in use, including while storing or transporting.

The empty tank(s) should be treated as if it was full.

Store the tank(s) outside of buildings in an open well ventilated area, away from spark and flames.

Do Not store the tank(s) or machine with tank(s) in an area where the temperature can rise above 120°F (49°C). If the temperature exceeds approximately 160°F (71°C), the tank will release highly flammable propane vapor. See Preparation in the Safety Section.

Do Not drag, drop, or abuse the tank(s).

Storage of the empty tank(s) should follow local and state regulations.

Park machine on level ground. Never allow untrained personnel to service machine.
