How long was the bar? What kind of saw and bar?
Were you bucking , limbing etc?
How did it happen?
Everyone of us do or should have chaps..That's cheap insurance BUT...Every now and again the mind will say,, "Hey, you don't need them JUST for THIS, it's only going to take a minute, why you will be done faster than you can put the chaps on".
Something similar to that happened to me once about 20 years ago..I was going to drop a small 3 or 4 inch tree,,just that one..no need for chaps..I thought,,I'll be careful. Back when I was young (i'm 74 now) I fasted sometimes (didn't eat anything but drank water). I was fasting at the time and was on a long fast probable day 15 or so at the time. I probably wasn't really thinking clearly but thought I was. The saw was a little Eager Beaver. Probably had a 14 inch bar safety chain..I'd bought the saw cheap and wanted to play with it..The thing was as loud as Satan making love and hard to start but it cut pretty well..The tree was located in a thicket so I cranked the motor before going. It as idled to high and the chain was rotating. OF Course I was going to be careful..As I made my way through the brush (and to this day am not sure exactly HOW it happened) the chain lightly brushed my right hip. Immediately I realized i'd been hit and killed the motor.. I told my girlfriend that I had cut myself and brought the saw out of the thicket, sat it down and she examined the cut..My jeans were cut through and through. She said no blood. I couldn't believe her. I looked and I saw no blood either..I was surprised so, right then and there, I dropped my jeans and looked at my leg.. Not a scratch..My girlfriend was amazed (that I was not cut) not that I dropped my jeans. ..She could not believe I was not bleeding either. I was not sure how that saw had cut my jeans but not cut me..I kept those jeans for years just because I couldn't throw them away. In fact I finally wore them out...Maybe it was a miracle..Maybe it was God or good luck BUT for sure it was a straight up Warning..I promised myself that I would never pick up a saw again unless I had my chaps on..But, like all of us do at times. I lied to myself because even now it's difficult for me to make myself put on chaps when I'm just gonna cut that one big branch thats laying across the trail..
I run an echo cs352 with 14 or 16 inch bar when I'm on the farm. Most of the time it's in the trailer and there are always dead trees or limbs falling across the trails..I always have my helmet, face shield gloves when I run that saw but,, like a fool, I still neglect my chaps at times..They are slow going on seem clumsy . I'm saddened that you were hurt but sometimes seeing a photo like that is what it takes to make us more aware..Bless you.
