Why won't my Manitowoc National Crane 800D Construction Equipment lift the load?

If your Manitowoc Construction Equipment jack won't lift the load, it could be due to a couple of reasons. First, check if there's enough oil in the system. If not, add oil to the reservoir tank through the oil filler hole. Another possible cause is that the release valve isn't fully closed. Make sure to turn the handle clockwise tightly to close it.
