In normal use, you should never have to adjust the tension. If the idler pulleys in the back get knocked out of position, this can change the tension, but it is very simple to gently move them back into position to restore the correct tension. The Operations Guide (found the Manuals / Download page) describes this procedure.
How often do I have to adjust the tension in the drive line/cable?
