That dosent sound very safe , I don't think that would be the way to go,I haven't looked at any of this make/model crown,I am just going by what I have run into on order pickets and the like.....with the carriage elevated,just as soon as you did take the hose off the carriage would drop and that isn't very wise OR safe!
There has to be a way to access the hoses on the bottom of the cylinders either thru the battery compartment or from the top down somehow,without looking at the lift I can't say which way it will be....
