Hadley Air Levelers

[La-Z-Boy]

I am a professional "button pusher" and here's another one I can's figure out. As I have stated before, the orphan has no paperwork, and I am just sure that this is a gadget that I will love to use, but I don't know how or when I might need to use it.
Does it work with the jack's? or is it an alternative to the jacks? Should I leave it alone? (that's what the DW says...)
I just leave it on STD RIDE all the time and roll on...
What am I missing out on??

Hadley Air package. To air level leave the engine running. Push the "SLS" button followed by the "Set" button. You should then see the vertical and the horizontal arrows illuminate in orange. (If you do not, repeat the sequence once more.) When these are flashing orange, let it self level and when both arrows turn solid green, shut off engine, You are good to go, you are air leveled.
When you restart. or start up anytime, do not move the coach (Other than a straight line) until the suspension is aired fully up. Failure to do this may cause fender damage if the front wheels are turned. The green LED just over the "STD Ride" will be flashing green at start up. If it is not, push the "STD Ride" bottom. If the light is flashing wait. It will then turn solid green for a short spell and then go out. You are then fully aired up. Then on you will see no lights on

Additionally, if you press "raise" momentarily the rear air bags will inflate to raise only the rear of the coach. It will stay raised until 10 MPH, then automatically revert to STD ride height. If you hold the "raise" button for more than 2 seconds both the rear and front bags inflate to raise the front and rear. Again at 10 MPH the coach will drop back to "std ride".

If you press the lower it will lower the entire rig a couple inches and reset at 10mph. And if you hold the lower for a couple seconds the rig will lower all corners the maximum amount and reset at 5mph. There is no selective lower like the raise feature.

PS - most likely after you do the air level described above if you turn the key to ACC it will probably defeat the air level and try to return to standard ride height - a Hadley software oversight in many units. Turing the key to IGN will definitely do this.

PPS - this control is my Wal-Mart leveler - it prevents pavement damage from your jacks.

Actually just pushing the SLS button alone puts you in "seek" mode. Drive around the lot looking for the arrows to turn flashing green (within leveling range). Then press set to do the level. Flashing orange means not in air level range. Solid green means air-leveled.

A) So, this air leveling system is actually somewhat intelligent? and somehow senses the ground to know when it is within the parameters to level itself?
B) I understand the part about not damaging the asphalt with the jacks, but this system can be used anytime the parking surface is very close to level, right? or I guess I should say what circumstances would determine which leveling system to use? Is it as stable as the Jacks? Used as a temporary level, like at the mall or when I need a quick level to run a slide out or something?
C) Other than leveling, I guess I cant see the need to raise or lower the front or rear of the coach. Is it feasable/practical to use pulling in or out of a parking lot, over RR tracks, or some other kind of sharp incline/decline?

"Is it feasable/practical to use pulling in or out of a parking lot, over RR tracks, or some other kind of sharp incline/decline?"

Oh, YOU BETCHA!

Let's say you want to do a U-turn through a gravel parking lot somewhere out in the boonies, driving across a swale which causes a dip in the front end. You'll rub your front generator door cowling and de-laminate the fibreglas. I know all about the dangers of this.....

Entering some campgrounds or traversing across certain grade changes will result in scraping your rear mudflap, pushing it up against the rear hitch and/or tailpiece. In some instances this has caused damage to the tailpipe where it exits the turbo. Spartan has a parts replacement campaign for this.....

Once you become familiar with this handy feature, you'll find lots of instances where you can and will use it to prevent damage to your coach.

If anyone would like a copy of the Hadley Quick Reference Guide that I picked up at Spartan send me an email. The scaned file is too large to post here.

Here's the Hadley SLS quick ref...

Is there any way to adjust this leveler? When I level mine, it is not level.

[ottffss]

You bet... And the Hadley SLS calibration procedure is one of those exceedingly rare times when it takes longer to read the procedure than to actually do it!

On your K2 the "calibration connector" - it's 5 ft long with a null dual Weather Guard connector on the end and also probably wrapped in that black plastic split wire loom material - and is most likely all bunched up and nylon tied underneath the Hadley SLS air manifold in front of the left front tire - just to the forward side of the fender cowl.

Here it is:

Thanks for the instructions, looks like something I can do. My only problem is finding the 5 ft connector in front the coach. How will I know if I get the right one? Do I look for it in front of the the front drivers wheel in the generator compartment? Boy, there sure is a big bundle of tie wraped wires in there!

Dl20415 Can't get any more precise location than that.... Spartan tied them there, coach builder might have moved...

[slabman]

Sure looks like an onerous procedure to me.......Maybe it IS easier than it appears, but I wonder how many of us would even bother with this adjustment?
