Question about Husqvarna , No.455 Rancher, 20" Gas - Powered Chainsaw
You may have a bent bar, or you could be putting the chain on a little too loose. Perhaps the chain is not getting lube ?
Possible that the chain tentssioner and or adjustment is loosening up as you are using the unit. Other than that maybe a defective new blade ?

If you look under the machine by the chain you'll see a flat head screw (next to the sprocket) which controls the bar and chain oil flow . Try to turn the screw and check if there's any oil flow to the chain . If not you will need to replace the oil pump (part # 537 10 55-02 which will cost you about $35.00) Hope this help

check the hose that goes to the oilway if everything checks clear you may have a crack in your oil tank due to excessive vibration and weak molding.

The problem is very likely to be a clogged but more likely faulty internal oil pump (especially if your chainsaw is old).
Hope it helps.

I would guess that you have already checked this but many years ago I got ahold of a bar for my stihl .029 super farm boss that had a slight warp in it. It would work fine at most r.p.m.'s but when you ran it wide open it would toss the chain. It took me awhile to find this and on mine if you wern't watching very close you would never see it. I hope this helps you some, Good luck and thanks
