The White 764 I owned had the two plug-ins for light and motor. When it is plugged in it is on. Unless yours is hard-wired for the foot control and wall plug you need the plug-in block (if it is in a cabinet-look up inside-if it is in a case look to the right of the machine or under the machine for the plug in block). I don't think you can use it without the block because that is what connects the foot control and wall plug. It is a nice machine-I never bonded with mine and donated it to Habitat.
