What's up with the HH 3500, full of water, rusted gear box, one friggin' year old. I just today after reading around found this a common problem simple to prevent just add cover and O ring on top cap....
I have the same jack. Mine came with a cover & I use it. I also use a plastic waste basket inverted over the top of it during long term storage. My chains, 7-pin & brake-away cable go up inside the basket & hook on to eyelets inside.
