Hydraulic cylinder protection...is it needed?
I have the HWH hydraulic leveling system and will have my 4 jacks fully extended and exposed to the elements for 1 or more months. Should I apply a spray lubricant or protective spray to the exposed c...

Well gang,
Been spraying down my HWH cylinders/rams with WD-40 for years, (about 6.5 years to be exact) and wiping them off but not totally, leaving a tad film on them. And guess what, they work flawlessly and there's no issues with seals and, operation. I've used ATF and get the same results. The rams on most hydraulic leveling systems are good quality but, are not totally stainless. There is potential for pitting and potential for a tad bit of rusting, IF, they're left out in the open, wet, potentially salty air, for an extended period of time.
We don't and haven't experienced long term stays at any one particular place so, our levelers are not subject to those extended/exposed conditions. They are however, extended for maybe a month or two INSIDE our RV garage. But, the climate control in there is a better better than the outside elements. So, with all that being said, if we were to stay in one place for as long as some of you do or, store it with the Jacks extended for a long period of time OUTSIDE, I'd spray them down with whatever you choose to keep the moist, wet air from them. Then, every once in a while, wipe them off and reapply. Good luck.
