The splitter, a 30 Ton Harbor Freight unit, which I got last fall, but only really started to use this week is leaking oil like crazy through the ram seal. The leaking stops after a while (gets hot?), but after the engine is turned off for a while, upon restart it starts leaking like crazy again. This isn't just a little leak. I am using the premium heavy duty hydraulic fluid from NAPA. What's the prognosis? I'm thinking there's no adjustment, but since I can't see in there, could that be a possibility? Are seals replaceable by a relatively handy owner, or is it a job only for pros with very specialized and expensive tools? I'll try warranty, but somehow I remember a 90 day deal, which is long gone. Thanks.
