View Full Version : Air shocks and Hydraulic jacks

02-28-2008, 11:53 PM
I have a new (to me), 2002 Yellowstone Diesel Pusher.? It has air bags and Dewald Hydraulic jacks.? From reading the instructions, my understanding is to push the Dump Air button and then the Extend All Jack switch? until all jacks touch the ground.? I then go into selecting pairs to level the coach.? It does work BUT, what I cannot understand from the instructions, and this is where I hope you all can help, is: First---What pressure should the air dump button take me too?? I believe? that it dumped to 50# and held.? I need to confirm that the first chance I can.? Does that sound right?Second--I havn't actually timed it yet, but it seems to take forever for the jacks to come down.? Does anyone have an approximate time limit for the jacks to reach the ground?Let me express my appreciation in advance.? I have been monitoring this forum for a couple of months and find it to be quite informative.? Thanks again,Ray

Have you tried the Dewald site - www.powergearus.com (http://www.powergearus.com)? I was able to find info on my system there. Hopefully, they will have better instructions or a good customer service department.

Yes, I have tried the website for Dewald and could not find the answer to the questions. I havn't tried to contact them by telephone yet. The 3 hour time difference is a killer because of work. Appreciate the reply.
