    I doubt anyone but Monarch has that print. Call them.

    Good practice at shutdown is to park the saddle at the...

    Sounds like you don't have a lot of experience with such drives and the wiring of an ELSR equipped 10 EE. That's a real pickle with a retro fitted machine with no documentation. There's a deep...

    The text he related to you off his container is correct and it is a recommended formulation for your application.
