After my incident on Sunday with my new Northern Tool splitter, which was replaced with another new one, I hit another snag. On Sunday evening after I got the new splitter home I split one round to test it out. Monday I worked too late and never looked at it. Tonite after work I was dying to use it. Although dark, I grabbed a chunk of wood to split for fun inside of my shed. The control lever didnt seem to work properly. It wouldn't return automatically, the ram would stop just as soon as I let go of the lever. I'd have to hold it until the ram was fully retracted. I first thought the oil may be cold, despite being 50 degrees. So I let the engine run full throttle for about 5 minutes and repeated the process with the same results. It was then when I noticed some kind of greyish oil coming from towards the rear of the control valve, where 2 seperate pieces are joined together by 2 allen bolts. I tried to tighten the bolts, which were a bit loose, but this made no difference. More oil would come from this joint when more pressure was used to retract the ram. I called Northern Tool, because I knew the store would close in 10 minutes. I talked to some guy who was familiar with the first splitter I returned on Sunday, due to paper in the hydro tank. I told him the trouble and said I would possible be returning the splitter for yet another new one. My three day return would expire today being I bought it on Sunday. So I needed for him to verify I made contact within 3 days. I told him I wasnt interested in returning the splitter but I wanted one that is without defect. He mentioned they could fix the valve. I told him I would settle for nothing but a new valve or new splitter. And I wasnt going to drop it off and drive back home, wait a few days for the repair, than drive back and forth again. Its almost a 60 mile round trip. But anyway I took a picture of the valve. Maybe one of you can tell me what you think the trouble is. You will notice the grey oil towards the right side of the control valve.
