How do I sharpen my electric chainsaw?

It's unlikely the sewer line has been damaged by roots as it's one solid piece from where it exits the house out to main in the street.

Mine does three 90 degree turns on its way to the street. However, past those trees it's a straight run. I am concerned, though. The driveway over the last 90 degree turn is pretty badly buckled. When I had the garage roof replaced, the contractor moved a very heavy truck over that patch, mashing the ground. The sewer line could have been busted. I think it's maybe a good idea to get the line scoped.

How did they do that with a trenchless system?

I don't know how they did it. It was Harry Clark (plumbing), AFAIK a reputable company. The sewer line starts at back/downstairs bathroom and goes east, doubles back 180 to head west for ~30 feet then turns south and runs ~50 feet to the street. Trenchless. They may have gone underground at junctures, i.e. dug holes. There was some concrete work in back of the bathroom, IIRC. At the --->west--->south turn they were under dirt. There's a round ~10" diameter concrete access plate over the final turn. I'm wondering if there might be trouble around there what with the roofer's heavy truck romping about 3 years ago over the spot.
