I've used a chainsaw frequently over the last 10 years and never once had an incident. I just bought a 27 ton Log Splitter and TWICE today had bad incidents. The first time I was splitting a 20 inch diameter twisted birtch log and the splitter was straining and building pressure and all of a sudden BAM! both halves went shooting like a missile in a V shape over 5 feet from the splitter! They both missed me but could have done SERIOUS bodily damage. An hour later I was splitting a small piece of oak and the splitter never hesitated but all of a sudden BAM! one half shot straight into the worst part of me you can imagine (Yup, below the belt!). I was yelping like a wild maniac. What's the deal with this exploding wood?? - is it happening because the wood has been frozen at 15 degrees for the last 4 days or is this typical? Does everybody wear an athletic cup and body armor when operating these things? Just looking for advice before I loose a body part....
