You need to have the coach running to level or do anything to the Hadley.
I rarely use the Hyd jacks. This is just me but it seems like a lot less stress on the coach when you use the tires to level it JMHO. I pull up to a camp site, leave the engine running and touch SLS (once) then Set (once) and you will see the arrows on the Hadley start to work. Within minutes the bus will level itself. The arrows (green) will stop blinking and the green light at the set button will remain on.
You are level, done. Turn off the key. Then you can open your slides and everything works smooth. I think I read Hadley will level up to a 3 degree slope on each corner. I have been in some spots that I never thought Hadley could level but it has so I am impressed. I know there can be as much as a 8 inch slope back to front or side to side and my cornerstone leveled itself.
Before others step in and say you are suppose to open your slides first then level,
that is if you use the HYD jacks. If you are using the Hadley air feature the cornerstone was built on the weight of tires, by leveling with air you are not putting stress on the chassis and the geometry remains the same. Never had a slide issue.
When you are ready to leave and air up just hit the Ride Height button. The coach will air up to ride height quickly.
Repeat do not do level with Hyd jacks then try to put out the slides.
FYI: Entegra puts a fuse in the buss fuse block (driver side front) that prevents you from keeping the motor running, putting out the slides (safety feature) wouldn't want anyone going down the road and accidently hitting a slide button. You can remove the #3 fuse and you can operate the slides with engine running or not. Good thing to know if you want to air up before you raise your hyd. jacks. Just a thought not advising anyone.
Also Hadley system will raise the coach 4 inches and lower 4 inches. I have used the raise feature many times out west in some of the campsites to prevent the rear from dragging or the front. It has saved many an Entegra flap in the back. Keep the coach under 10mph. Once you go over 10MPH the system will go back to the 12 inch ride height automatically.
For the sake of time there are many features that the Hadley system can do. I love the feature. Give it time and get to know what it can do. At rest stops etc... just hit the right button and you are level. When you take a corner at an exit ramp you will feel the system level you. Same with crowns in the road and high winds. as long as the engine is running it is working to keep you level. Fantastic system and the ride is great.
Call CS or call Spartan, they have a cheat sheet on the operation of the system maybe they can email it to you. I hope that helps. If you send me your Email address (PM) with it I will scan the cheat sheet for you.
