Agree with Cropduster on the leveling before moving the slide. Running the engine is not needed, unless your batteries are really low and that is the only way you have to charge them (unlikely).Regarding the 'jerking' when moving keep in mind that Phoenix has used two different brands of slides. Starting in 2017 they moved to a Schwintek one which operates differently than the old one. The Schwintek does 'jerk' as it moves and that has nothing to do with the seals after the initial movement. I went over this with Kermit at the factory and he told me that is the way the Schwintek works.As to lubricating the seals and mechanism I was repeatedly told by several different people at the factory (including Kermit) that the gears and seals should absolutely NOT be lubricated in any way. I have asked on three different occasions including my last stop there for repairs and got the same answer.Now for those that DO lubricate seals and gears, I trust your experience and am not in any way trying to contradict your process. Just repeating what the factory folks told me.
If in doubt ask LCIhttps://youtu.be/8KbVRFMo1Rghttps://youtu.be/_TriNbci200
JTrax, did they tell you why the slides and seals should not be treated/lubricated?
