If I'm parked for a long time or there is a rain that splashes sand or dirt onto the leveler rams, I clean them off before retracting them. I use silicone spray on a clean, dry cloth to wipe them down.
We don't have those HWH type return springs because our Kwickee system is hydraulic power out / power in. I replaced 2 of the HWH jacks on my 02 Brave because they wouldn't return properly. So far....no trouble with the Kwickee system but I level the coach manually instead of using the "auto" feature which seems to take longer.

Since the pump Dexron III + transmission fluid, I keep some in a bay. Once n a while I will put a little on a rag and wipe down the piston. I figure if it's good enough for the pump, it's good enough to wipe down the piston. I little dab on a rag will go a long way.

(RVM-14) It is what it is, and then it is what you make of it.
Indy.. I kind of wonder.. The jacks on my coach are power gear, Which I think MIGHT be the same now as Kwikee. (NOT sure) and the instructions specifically say to use Silicon... Now Silicon lubricants do not mix well with other lubricants so I kind of wonder why they said this.. But they do.
That said... To the original poster.. Go to the company web site and download the maintenance manual for your product.. (That is way easier than digging out and digging through the paper manuals)
With my power gear I keep a quart of Dextron III tranny fluid (The hydraulic fulid they use) handy, as well as that spray can of Silicon.
Home is where I park it!
