If you use the dump switch to dump your air......and don't use the jacks, such as when you store it, and don't put the jacks down. When you start the engine, do your airbags inflate ?? or do you have to hit the retract all button on the jacks, even though the jacks aren't down?
supercub,
Yes, it would be nice if you'd put your coach/model/make/ etc. and, also the brand leveling system. You see, In all that, the make model of the leveling system is the most important. But, leveling systems differ between different makes of chassis's on coaches.
For instance, in our coach, an '04 Itasca Horizon, 36GD with the C-7 330HP CAT, we have the HWH 625 Computer Controlled Automatic Leveling system. That system has two styles of dumping the air from the bags. In the Automatic side of the operation, HWH takes care of the dumping and, when it comes time to air back up, HWH takes care of that when you hit the "Store" button. The jacks will begin to retract and, the air bags will begin to fill.
On the Manual side of the operation, it's pretty much the same thing with the only difference being that, manually lowered the jacks instead of HWH taking control.
Now, if you WANT to dump and, not lower the jacks, in the HWH system, you still have to turn the HWH system on but, just hit the dump valve button. And, what's most important here is, you cannot do anything without SETTING THE PARKING BRAKES! There is an interlock ground connection that is provided by setting the brakes.
So, to answer your original question, depending on WHO is the maker of your system, at least in the HWH 625 system, you must either push the "Store" button or, release the brakes, in order for the bags to start filling. At least that's the way I understand the HWH service manual and owners manual.

On edit: Apparently I was typing when you answered about your make and model. May I ask, what chassis?
