The serial number on the AbSolo® consists of an alphanumeric code that identifies the production batch of that particular unit. It will start with 2 or 3 letters (most frequently ABS or SW) followed by a series of numbers and letters. The sticker with the serial number should be located on the U shaped base near the rear of the unit before you come to the movement wheel. Older units will have their serial number located on the back of the center foot support brace.
When asked for the serial number and you are unable to locate the sticker, please feel free to send a picture of where you believe the serial number should be, and a picture of the entire unit to Parts@TheAbsCompany.com and we will be happy to assist you in determining the make and model of your unit.
