How do I use the automatic needle threader on my Singer 1120?

First, raise the needle to its highest position and press lever (A) down as far as it will go. Pass the thread around guide (C), then pass it in front of the needle around hook (D) from bottom to top. Release lever (A) and pull the thread through the needle eye. Remember to turn the power switch to 'O' (off) before performing any of these operations.
