Question:
I have a Husqvarna 455 rancher with 20 inch bar. I purchase the Husqvarna chains for it. The chains get stretched after about 3 or 4 tightenings. Why? Plus when I put on a new chain, it takes up at least half of the area allowed for future tightening and adjusting. Is it the chains? I don't see the need for a new chain so soon all the time. What is happening? This is less than a year old chain saw.
