Sprocket Cover Nuts Fall Off

[Mick]

Chainsaw is a Stihl MS 271.

I have had this happen twice now, one of the two sprocket cover nuts fell off. Did not notice until i was walking the site after finishing the job, both times! Found one of the nuts on the ground, by good fortune. I believe that i had tightened them enough, but apparently not.

I am thinking of replacing them with Nylocks. What do you think?

Need to loosen and tighten them several times a day to adjust chain tension, etc. Do you want to do that with nylocks?

Maybe check them periodically ?

Thank you Philbert, and thanks also to treesmith for the confirmation. Yes, checking periodically is what i shall do. It is quite permanently embedded in my memory now.

I think also i'll add a note into my manual. I have taken a chainsaw safety course and have and use all the proper equipment. But i do lack experience, and get out to the hiking trail or the land trust bush lots for maintenance only a few times a year. So i review the manual before each chainsaw work day. Every time i start that thing i am in awe of the sound and the power, and of the need for care.

I carry extra bar nuts, along with a few other, basic things, in each saw case.

I have a small tool box specifically for the chainsaw. I'll pick up a couple of spares to add in.

maybe your saw got married........HA

That happens to me on the 066 every now and then. We cut some trees at a cemetery in the snow one year. I didn't check to make sure nuts were tight and one fell off making a stump cut. Went back to grind stumps in springtime and found the nut in the sawdust. Nobody would believe me, but it was still there lol

Well, i am glad to know that i am not the only one, but sorry about everyone else's troubles with these things
