Lift the head of your Prospero+ and remove the bowl. Make sure the screw is not in place on your EasyWeigh Scales Attachment. Line up the edges of your Prospero+ with the EasyWeigh Scales Attachment and lower your Prospero+ onto the EasyWeigh Scales Attachment. Secure with the screw. Re-fit the bowl to your Prospero+. The EasyWeigh Scales Attachment is now ready to go. The EasyWeigh Scales can fit the original Prospero stand mixer but it will not follow the lines on the body of the machine.
