I just bought a 2009 Huskee 22 ton splitter. Looked super clean, like new, seemed to run fine. However, when splitting larger rounds, nothing enormous, but anything in the 14" and over range, the splitter pauses upon contact, then after 2-3 seconds, powers through. Is this normal? I've read everything from normal, to valve issue, to pump, to low oil to clogged hydraulic fluid filter. Can anyone assist, I'm getting started late on my splitting and I'm NOT calling the oil man$ Thanks!
