Wow, I always avoided the lubrication of the jacks because of the advise from HWH, but just a quick squirt of WD40 and a whip down and the BAM! work like new
retracting all 4 in 3 minutes or less. I found a loose hose connection that is where the leak was.
Thanks for the advise. I would think for long periods of time when the jacks are down it would be good to reapply the WD then wipe down before retracting to avoid the dirt issue! JMHO!
Happy Holidays!
