Important: The oil fill plug has a vent hole (D) that
must be installed on the top of the gear case cover

burns or death.
• Keep gasoline away from sparks, open
flames, pilot lights, heat, and other ignition
sources.
• Check fuel lines, tank, cap, and fittings
frequently for cracks or leaks. Replace if
necessary.
• Before replacing the fuel filter, drain the fuel
tank or close the fuel shut-off valve.
• If fuel spills, wait until it evaporates before
starting engine.
