SAFETY

WARNING!

The engine must not be started when the driver’s floor plate or any protective plate for the mower deck’s drive belt is removed.

Safe Handling of Gasoline

To avoid personal injury or property damage, use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive.

•Extinguish all cigarettes, cigars, pipes, and other sources of ignition.

•Use only approved gasoline containers.

•Never remove gas cap or add fuel with the engine running. Allow engine to cool at least two (2) minutes before refueling.

•Never fuel the machine indoors.

•Never store the machine or fuel container where there is an open flame, spark, or pilot light such as on a water heater or other appliance.

•Before you begin refueling, minimize the risk of static electricity by touching a metal surface.

•Never fill containers inside a vehicle or on a truck or trailer bed with plastic liner. Always place containers on the ground away from the vehicle when filling.

•Remove gas-powered equipment from the truck or trailer and refuel it on the ground. If this is not possible, refuel such equipment with a portable container, rather than from a gasoline dispenser nozzle.

•Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device.

•If fuel is spilled on clothing, change clothing immediately.

•Never overfill fuel tank. Replace gas cap and tighten securely.

•Do not start the engine near spilled fuel.

•Never use gasoline as a cleaning agent.

•If leaks arise in fuel system, engine must not be started until problem has been resolved.

•Check the fuel level before each use and leave space for the fuel to expand, as the heat from the engine and the sun may otherwise cause the fuel to expand and overflow.

Never fill the fuel tank indoors

WARNING!

The engine and the exhaust system become very hot during operation.

There is risk for burns if touched.

Allow engine and exhaust system to cool at least two (2) minutes before refueling.
