I also store my triked Wide Glide on the lift. When you're at the highest locking position make certain the support arms are in the notches then slowly release hydraulic pressure on the bottle jack so the weight settles on to the lift itself. With the hydraulic pressure off the bottle jack and the weight on the lift itself you shouldn't have any issues storing the bike in the air...
Yes, that's what I do. I then tighten up the lift back up but the hydraulic cannister is then not bearing any weight until it is time to take the bike back down.
I do. What would you like to know? See my post here.
Link doesn't work for me.
EDIT: For the thread, the Strongway 5-ton air/hydraulic jack is no longer available on the Northern web site. Strangely, they have a bunch listed on eBay.
