Hello,
The actual installation of the 39-070 is quite simple but you might get stuck if you need to pry up the sill to access your old operator. The video below might help with that process, even though it features a different kind of operator. Once you can access the operator, you just need to unscrew the base and release the arms from beneath the sash. Reverse this process to reinstall your new operator. Thank you!
