Still want to forgo using chaps?

Started using a chainsaw when I was a teen . . . and never had any injuries from a chainsaw . . . I think mainly because I learned at an early age of how to stand and handle the saw to avoid kickback.

That said . . . doesn't take a rocket scientist to figure out that even the most careful and safest person can have an accident . . . and when safety gear is so much cheaper than my health insurance premium . . . well it only made sense.

Plus . . . when I put on my chaps and hard hat my "cool" ness factor goes up at least 10x . . . and honestly . . . when scrounging around here . . . orange chaps, orange hard hat and orange vest = no one stops to ask questions as most assume I am a professional and doing contracted work . . . at least the few folks who have walked by and chatted with me have seemed to think I was working for the City.

Unfortunately they do not. The nut tightens to press metal against metal. the adjustment pin that fits into the hole in the bar is what actually keeps it from slipping under power and vibration. The tensioner spinning free is the problem.

No, the pin does not keep it from moving. The nuts on the clutch cover do all of the holding. On way too many occasions I have left the bar nuts loose (not enough torque) and the chain has loosened up every time. I had an old Homelite 360 pro that I broke the adjuster on, I removed the thing so I could Pull the bar out by hand and tighten the nuts. I used it like that for almost a week 7 hrs a day while waiting for parts to replace it. It worked just fine without the pin.

Over tensioning the chain ( rubberband tight on the bar) will cause the chain to stretch as was alluded to but not mentioned specificly in a previous post on proper chain tension - that would be why the particular chain has gotten to long and you are out of adj. range. additionally running the chain that tight will cause accelerated wear of the bar and chain compounding the problem.

We agree, it's simple physics, and common sense from a mechanical standpoint. I didn't feel it was worth the argument......
