My new ECHO saw seized up after ten minutes of use. Dealer put oil and gas in the thing and didn't grease the nose. I got it going again and didn't say anything, but it shows how lacking our world has become for getting the small details right. This dealer has sold thousands of saws!
I haven't greased the nose in 30 years and have lost one tip in all of that time. I used to cut a lot of ice when I was beaver trapping, and didn't even run B&C oil; the ice made a good lubricant.
