Hello! I'm sorry to hear that you're having trouble. I'll do my best to advise how the 39-070 operator is meant to work with the 39-170 bracket.
After you install the 39-070 operator and the two 39-170 brackets to your window, follow these 3 steps:
- Unlock the bracket opening on operator using the metal latch beside the slots.
- Open the operator arms wide enough so that the cross-arm aligns with the bracket, then insert the bracket prongs into the slots.
- Lock the bracket by flipping the metal latch the other way.
