I have an older model but here are the instructions for synchronizing the powerhead. This applies when you remove the powerhead.
1. Use the crank to fully retract post.
2. Crank jackpost one turn in opposite direction.
3. Ground powerhead to jackpost or trailer frame.
4. Push switch away from jackpost housing (as if retracting post). HOld switch until motor stops running (as if jackpost is retracted all the way).
5. Install powerhead and tighten set screws.
Hope this helps.
