A simple procedure covered in the manual. Tested with kill switch wires disconnected. But see above-can't give 10 year review on this. This is our fourth Echo. Also, I dont like how you tighten the chain.

Echo CS-310 Final Thoughts
"Easy to use and handle."
Puts just the right amount of oil on the bar. When used correctly, it seems pretty unstoppable. I will report back later on how that works out. There are some important limitations. Loved not dealing with the gas or the pull start.
