on the motor base there is a hole. put the blending cup onto the motor base with the handle directly over the hole, (if you look inside the handle you will see a spring)
if you look on the bowl cover where the feeder (chute) is you will see a pointy bit facing down.
as you stand in front of it make sure the pointy bit is to the left of the handle of the blender cup. you then have to turn the cover to your right. the pointy bit will then push down on a plunger which presses the switch in the hole in the motor base.
