hi everyone, buddy of mine got a wood splitter very small non towable starts right up and runs but doesn't have enough power in the cylinder to split really anything except really really small wood. Any hardwood or normal lengths it just jams up and doesn't have enough to push through it. Outside of sharpening the actual splitter V in the front thats pretty dull any ideas what the problem might be? They wouldn't sell this thing if it didn't split anything. reservoir is full but maybe air in the line? it has a screw in hydro filter that is dented would that cause loss in power? do the pumps get so weak on these things they can't do anything anymore? thanks not a big deal just wondering as its lost its power here is a pic of it.
