Does anyone have an operator's or service manual they no longer need, or know where I could get one?
There are well over a dozen different versions of the 305.5. If you start with a Serial Number that would narrow the search down.

OK, so your manuals are as follows:- SEBU8574 - Operation & Maintenance. Priced from US$49 SEBP4583 - Parts. From $109 KENR5850 - Service. This manual will also contain SEBU8574. From $630. Be careful of used manuals on eBay. They are often more expensive than new.......!!
Thank you.
