Shortly after moving into my new home, I realized one tree in the yard needed trimming. There was an owner’s manual on the shelf next to the chainsaw, but I ignored it. How hard could it be?
I filled up the gas tank, started it up, and went over to the tree. After awhile the saw seized up. I took it to the local mechanic.
Turns out you need to add oil to the gas so the chain is lubricated. I’m lucky I didn’t toast the engine. From that point on, I read manuals.
