To ensure safe operation
Fire and burn hazard
Gasoline is extremely flammable, and gasoline vapor can explode.
Use extreme care when handling gasoline. Keep gasoline out of reach
of children.
Add fuel before starting the engine. Never remove the cap of the
fuel tank or add gasoline while the engine is running or when the
engine is hot.
Refuel in a well-ventilated area with the engine stopped.
Refuel outdoors only and do not smoke while refueling or handling
fuel.
Allow the engine to cool before refueling. Fuel vapor or spilled fuel
may ignite.
The engine and exhaust system become very hot during operation
and remain hot for a while after stopping. Contact with hot engine
components can cause burn injuries and can ignite some materials.
Avoid touching a hot engine or exhaust system.
Allow the engine to cool before performing maintenance or storing
the tiller indoors.
Tighten all fuel tanks and container caps securely.
Store fuel in containers specifically designed for this purpose.
If gasoline is spilled, do not attempt to start the engine but move the
tiller away from the area of spillage and avoid creating any source
of ignition until gasoline vapors have dissipated.
