Hi Bill,
Thank you for contacting Husqvarna. The tube comes off the opposite way it was put on. Just turn it counterclockwise until it unlocks. If you can't unlock it you might need to get to your local dealer. You can find your local Husqvarna dealers for sales, service, parts and manuals using the link. /images/us/homeowner/home/ .
Hope this helps.
Thanks again from the Husqvarna Technical Services Team
