Vintage Husqvarna Service Bulletins

This thread is for the clear posting of Vintage Husqvarna Service Bulletins Only.

The thread will be technical in nature

There is wealth of information in here. Start reading.... sift through to find what you may need.

If you have service bulletins from back in the day or have them on PDF please PM me and I'll send you my email address. If you only have paper copies we can handle that via mail.

The clearer the documents the better!
