I picked us an old Stihl USG in really good shape. Its working but I have yet to mount it and test it on chain. The cutting head isn’t moveable like the new USG model. Looks like it’s mounted at a 40° angle. Is there anything I should know before cutting. Thanks. I’m very new to this page so I hope this is in the right place to post. Anyone know the model numbers for the Stihl disc for 3/8 and 3/8pico?
