Just a quick hello to your forum members. I’m a part time firewood processor, but have been doing it 45 years. Certified level 3 chainsaw safety. Currently rebuilding chainsaws in winter doldrums. International Society of Arboriculture member. I started hunting for Husqvarna common service tool/auto tune info here, and became impressed at what veterans know and that they share their info freely, without belittling the less informed asking the questions. Keep up the good work!
