Air bag maximum and dump operations?

I'm going to learn the airbag system this week. When you want to raise it to max height, do you just hold the raise button in until what? Also on dumping, hold in until stops lowering? Engine on or off? Just don't want to damage anything!

Correct on both accounts. When raising, pick a spot outside your front window, watch coach rise up, when no more movement upwards your coach is fully raised. I believe on your year coach you need to shutting switch off after raising or it will go back down. Keep in mind the front will come up faster than the rear. Eng on will work faster but ign on, eng off will work also, just slower as you're only using the 12VDC compressor

Another way to check if your bags are extended all the way, is to look at the air gauges and when they stop dropping and pressures are back up, that is all you get.

There are mechanical stops going up and going down, so you can't hurt anything by raising or lowering the coach "too far".

We had a discussion on this subject (and the use of safety stands) a while back:

Safety Stand Placement

I do as craneman wrote and then I turn the key off and as long as I leave the key of my rig will stay at the top, at least for 24 hours. I haven't check it any longer.

Went out and gave it a try. Works fine. I was impressed how high it goes. Awesome system and no friggin jacks to fail. The pick an object and watch it really helped raise it to maximum.
Thanks everyone for the help.

I have a Harbor down the street and a 20% coupon. Do you think 4 should do it ? Thanks much.

4 can be used to "keep the coach off you". Place behind the front wheels and in front of the rear= toward center of coach.

But you will need one inboard of each air bag if you are doing any work on it, as 4 put a strain on the structure.

And your 20% off coupon will be on just one of the 8.
Damn fine print.....

Easy to harvest more coupons.....various magazines, inserts, friends, etc

Ok I'm still new.
But after I shut down the engine usually after a day or so the coach eases on down to a certain height and stays there.
Then when we are ready to go somewhere of course as it resumes to the normal pressure it raises up.
So at the point where it's been setting for a few days is it ok to get underneith as long as you can fit.
I did this a few weeks ago when we replaced our floor and I got the passenger Captain's chair out.

No!

You never know when the coach may relevel, or if you might inadvertently bump something that causes an air leak. 

Unless you are on a level surface with wheels chocked and have dumped the air from the leveling all the way down to the stops, it is not wise to work under the coach without safety stands and wheel chocks.

If the wheels are chocked so the coach can't roll and all the air is dumped and you still fit in that small space, you can then consider it.

Not to say that people don't do it, but it is not wise given what could happen (and has happened).

Thanks.
I just went on line and there are quite a few wheel chocks to choose from.
The PO didn't pass those on to me.
Any ideas for our size tires.
