I got the 4-ton splitter about a year ago and tried it outto see if it worked, but have not used it since. The manual advises to lube it with lithium grease but it is not clear, at least to me, about exactly where to apply it. I called them up but still didn't get a response that helped. It sounds like one of the places it's to be lubed is on the frame where the log rests but that doesn't seem to make sense to me, it's not a moving part. Anybody have the answer for me? Ray Mac.
