How do I properly fill the fuel tank on my T100 Series Lawn Tractor?

Turn the engine OFF and let it cool at least two minutes before removing the fuel cap. For Hydrostatic models, fill the tank to the base of the filler neck. For Foot Control CVT and CVT models, fill the tank to no more than ½" below the bottom of the filler neck to allow space for fuel expansion. Use only clean, fresh unleaded gasoline no more than 30 days old. (Page 12-13)
