Chainsaws

While using my Rancher 55 chainsaw, with the chain break engaged for no longer than a couple minutes, I discovered that the heat from the unit had warped the casing along the brake mechanism. Because of this warping I am now no longer able to engage the chain brake, and risk a danger to normal usage. Below are several pictures embedded in video depicting the heat warping of the case. Please advise what to do. I am a contractor and have relied on Husqvarna products with confidence, but such a design flaw concerns me. I am seeking manufacturer support to remedy this issue with a part replacement. Because of this incident not being a case of user error (the unit was in a low speed idle), I am requesting support for part replacement. Thank you.
