adjusting timing belt wheel ?

Hi Sonia,
To get to the timing belt wheel you would need to remove the plastic covers at the back of the machine but as yours is an electronic you would have to be very careful that you did not damage any of the electrical components. Patterning problems can be caused deep within the machine.
I think you would be best advised to contact a mechanic who could look at the machine for you. A search for 'knitting machine repairs' will give you some places to contact. There are also some listed on the guild of machine knitters website.
I do hope this helps,
