Landing leg activator / general technical specs?

[cwsaint]

Anyone know of a good source for general DRV technical specifications? Right now, I am trying to research a problem I am having with the landing legs on my Select Suites rig, but it would be nice to have a resource for other potential problems, as time goes on.

To my more immediate problem, the landing legs on my rig have started to extend unevenly. Upon pressing the extend button, one leg goes down. When it hits something solid, the other leg descends. Any ideas on what the fix might be?

Thanks and best regards,

Carl
