exhaust gases contain carbon monoxide, a deadly

poison.

MAINTENANCE AND STORAGE

1. DO NOT store mower or fuel container inside where

fumes may reach an open flame, spark or pilot light

such as in a water heater, furnace, clothes dryer or

other gas appliance. Allow engine to cool before

storing machine in an enclosure. Store fuel

container out of reach of children in a well

ventilated, unoccupied building.

9. 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

10. If fuel is spilled on clothing, change clothing

immediately.

11. DO NOT overfill a fuel tank. Replace fuel cap and

tighten securely.

2. Keep mower and engine free of grass, leaves or

excess grease to reduce fire hazard and engine

overheating.
