You must have the screw side to the back of the vacuum and press the handle adjustment lever to install the handle.
To remove the handle, it will require two people. First, remove the pod from the machine. On the handle, below the button labeled as "Lift-Off" there is a small hole. Using a thin flathead screwdriver, press the lever inside this hole. With your other hand, press the handle release button. While these two areas are depressed, have the second person pull the handle off the unit.
