Jack Problem

[Paul Steiner]

I use a mini pallet jack to move my machines around, great system for me and my shop. BUT I think my pallet jack broken, a week ago I moved my tablesaw and bench. Yesterday my jack would not lift at all. I adjusted the pin that engages the jack and nothing. Also I did not find any fluid or oil on the floor so I do not think it is a leak.
My question is can this be fixed? Can you recommend a possible troubleshooting procedure or fix?
Is it worth fixing? The jack can from Northern and it was $250. Unfortunately it is 6 months beyond the warranty of the jack.

Not to many things that can go wrong with a hydraulic jack. Low/no fluid or rings. Make sure the sealing pin is operating properly. Usually operated by twisting the handle or a lever. Other than that, not much to go wrong.
