MS461R Chain Tension Issues

[farmer steve]

Well i tested this problem again. I let the chain get dull, and it immediately gets grabby in the cut, bogs down, and then the chain gets loose again in no time. I still don't think this is correct but it certainly seems it is tied to the chain being dull. Does this still make sense to you guys?

have you checked the threads on the chain tensioner screw/bolt? i never had a problem with the chain getting loose after the chain got dull.

Yes I inspected the threads and they don't appear to be stripped or messed up.

I used the saw yesterday. I noodled the last huge Scarlet Oak round I have (about 5' in diameter), and cut it into 1/8 pieces (still hard to carry).

I then had some 3" sapling stobs at about 2' above ground I dug around with a shovel and then cut off (yes I hit dirt doing this.) After the 3rd stob, the chain was dull and the chain drooped an easy 1/2" below the bar. Are chains this sensitive when they become dull, then stretch, and lose tension??

The second you hit dirt the chain becomes almost useless dull. So the second and last round you were really making heat forcing the saw through the cut and useing the HP of the saw to cut not chain sharpness.

I can see this being the problem.

Last night I didn't realize you hit dirt digging down.
