Brother LT2-838 not turning lower gears

[Winks]

When the wheel is turned the timing gear turns without moving the gears. If I turn the handwheel toward the back, it catches the knob and turns the gears fine. Is there a way to reverse that lever or knob so it catches the right way? Let me know if there's a way to insert a picture if it would help.

A picture or a movie would help.  You can put the movie on YouTube and link to it here.
