He did recommend wiping with a dry cloth prior to retracting if extended for a long period of time, and if necessary remove sticky stuff by using soap and water and then a dry cloth. For lubrication they recommend a dry lubricant like CRC Dry PTFE spray, which is not sticky and won't attract dust.
Having been raised using WD-40 I would myself, if necessary, use it for removing rust (should it occur) or general cleaning of a jack rod, but then I'd wipe it down with a dry cloth given my discussion with Power Gear.
HWH, with whom I also just talked a few minutes ago, says WD-40 is okay for cleaning, but after cleaning the rod should be wiped with a dry cloth, and that no lubrication of any kind is required. They did not issue any warnings about avoiding WD-40, and they in fact recommend using it for cleaning if necessary, but not for lubrication.
If Power Gear I would absolutely follow their recommendations...
If HWH - they have great info on line and very helpful _ AZPete here in iRV2 as a resident contributor
From HWH FAQ's ...
49. Is there something I can lubricate my jacks with to make them retract faster? How long should it take to completely retract my jacks?
Lubricating a jack rod can help with retraction time but if lubrication is necessary, there is most likely a problem with the springs or the jack itself. The only thing HWH recommends to use is WD-40. Refer to the following link for jack maintenance information: ml47149.pdf.
The following link gives detailed information about allowable jack retraction times: mi9553.pdf
From above link - If the jack rod has been greased or silicone sprays have been used on the jack rod, use WD-40 to loosen the grease or silicone and wipe the rod clean.
Can I store my coach with my jacks extended?
Yes, this will not hurt the system
55. How long can I leave my coach parked with the jacks extended?
As long as you want. We recommend operating the system occasionally if possible.
56. Do I need to do any maintenance on the jacks or slide-outs while the vehicle is parked with the jacks and slide-outs extended?
There is no necessary maintenance for the jacks or slide-outs while the vehicle is parked. If desired, WD-40ģ can be used on the jack rods right before storing the jacks if dirt has collected on the rods. Refer to the following link for jack maintenance information ml47149.pdf.
57. If Iím parked for a month or two, should I occasionally operate my system?
Yes, it is good to operate the system occasionally but it is not required.
Bottom line - use what ever you are comfortable with... I will follow manufacturers recommendations where ever I can.
