Whenever you intend to use your chainsaw in that altitude we recommend that you stop by the local authorized Husqvarna service center in that area to have the carburetor adjusted to meet EPA standards.
It is a violation of the E.P.A. for anyone to adjust the carburetor other than an authorized service center when the equipment is supplied with tamper resistant adjustments. For this reason the tools required to adjust tamper resistant carburetors are not sold to the public.
