Don't worry about it. That machine will last forever.

canguy,
Thanks for your response. I was just trying to avoid a bushing failure, but they must be lubricated for "life". It seems like many products are designed to be "throw away" items after a certain period of time. I have always tried to keep things running longer than the design calls for by simple maintenance.

FYI, I wrote to ECHO to ask about lubricating the "bushings" I was told this model has. This was the response:
"Thank you for your recent e-mail to ECHO Incorporated in regards to your brushcutter/trimmer model SRM-2601. This model features a sealed bearing system which does not require any service". I will take the collective advice and not worry about it. Charles Ranheim
