Everett,
Thank you for your question!
We recommend you apply lube as recommended in the Owner's Manual. The Weed Eater One is a very maintenance friendly machine, but it never hurts to WD40 some areas that you want to keep rust-free, especially if they are moving parts with a load of any kind. Not required, but never hurts.
Best regards,
Benji C.
