The XR-65 and the XR-65T are the same except that the T indicates the sewing machine was sold with the Quilting Table and some accessories for quilting.
To thread the sewing machine, first lift the presser foot and use the handwheel to raise the needle to its highest position. The thread take up lever should be at its highest point. Place the spool of thread on the horizontal pin secured with the appropriate cap. Make sure that the thread comes off the spool from the bottom front, (Also check that the catch (for holding the thread when not in use) on the spool is at the back of the pin.) Then bring the thread to the thread guide at the back of the machine then down past the reverse lever and back up the the thread take up lever. Wrap the thread around the take up lever so that it slides into the slot and then goes through the hole in the take up lever from right to left. Bring the thread down again and place it behind the guide above the needle. Then thread the needle from front to back.

I hope this helps.
