Thanks for posting! Your window operator reminds me of the 39-399 Roto Single Arm Operator, the opposite version is the 39-400. To determine if this is the replacement you need, carefully look over the diagram below.
These operators use the 39-541 Roto Casement Track Slider which is compatible with the 39-542 track. The crank handle is the 39-232.
We do not have an installation instructions for this casement operator but it should be pretty straight forward. One thing to be mindful of is that, you'll need to make sure to position the arm so that when you are closing the window, you are not turning the gear farther than intended. This may take a bit of trial and error but you should not have to force the window to shut.
Please don't hesitate to reach out to us if you get stuck during the installation, once you've received the hardware.
