Default How do you convert a hydraulic jack to air

How do I convert my new hydraulic jack shop crane to run off of air? I saw a hydraulic jack that would run off of air at Harbor Freight for $79 but I do not want two long stroke 1 ton jacks.

sorry about the double post

Chuck

Your best bet is to buy the long jacks with the Air pump already installed. I know you used to be able to buy the little 6" air pump that screwed directly into the manual pump area but im not for sure if there still available.

It's one on a HF 1 ton shop crane that I just picked up with a 20% off coupon for $119 + tax.
