G'day and thanks for reading - I have a small electric hydraulic log splitter that isn't working properly. It's only a 7 ton (and that's the full official specs, it probably does less than that in reality when working properly) but it used to split 12" rounds no problem, especially when cracking or starring a bit. Although only a bit over a year old it doesn't split anything bigger than 4" round now and is definitely nowhere near as powerful as when first bought. Yes, it's a cheap chinese made unit but it did a job for me and I'd like to get it back to full strength if I can. I had a mechanic mate check it and he says the electric motor is fine and the fluid levels are good. I dropped it into a hydraulics place for repair but they said it was too small for them to bother with. My mechanic mate suggested it could be the pressure valve has failed or is faulty meaning it operates but with reduced pressure, hence the ability to only split <4" rounds now. Can anyone suggest something I can do to diagnose and repair my splitter? Thanks in advance!
