This may help as most BL/Brother machines should thread the same way.
First, roll the hand-wheel so the take up lever is in the highest position. Look at the machine # 2, #3, and # 4 located on the front of the machine. You need to follow the path shown on the "U".
The thread should go in a "U" shape. Down on number 2 side, then around the U on the bottom for number 3, then to the position #4..
At number 4 you have to hook the thread into the take up lever.Then follow to #5 and thread path.
Look at page 14 in the manual for step by step tips on threading. Hope that helps.
PS: In your picture, the thread is incorrect from position #2.
Cut the thread from the spool and pull down though the machine. Don;t pull out thread backwards through the top of machine.
Always re-thread starting fresh at the beginning so you catch all the steps.
