I let my grandson use my new Stihl chainsaw and he left the brake on when he started it. Now I can't get the cover back on. Did he wreck it? If so, how can I fix it?
Nothing wrong with starting the saw with the brake on.QUOTE]
Stihl actually recommends that you start the saw with the brake on.

All chainsaws should be started with the brake on.
What cover are you having trouble trying to put back on? I had trouble a few times disengaging the brake on my ms250. Thought I would break the plastic pushing on it so hard. Took it in to get it checked out and the shop couldn't find anything wrong with it. Someone must have been a bit hungover when they assembled mine.
My Husky 51 is the same way. If the brake gets set with it off the saw I have to fasten it in the bench vise to unlock it. But to make up for that, it will set by almost just breathing on it.
I took the saw to the shop. The cover that I'm talking about is the one that is over the sprockets where the chain meets the motor. The thread in the cover was stripped. Another question is - does it hurt the saw if the motor is gunned with the brake on?

A photo or two would be very helpful. I am not familiar with a STIHL saw that has a threaded cover - might be a newer model (?).
Generally not a good idea. It causes a lot of friction/heat on the brake band and the spur sprocket or clutch drum (if they turn blue, they have been overheated). This heat can damage other components, especially the plastic housing, covers, oil pump drive gear, etc. You may see some melting or discoloration of these parts.
I always start a saw with the brake on, but release it before pressing the trigger. Sometimes people forget and try to run with the brake on for a second or so, but that should not cause significant damage.

My grandson didn't know there was a brake and must have put the cover on wrong when he tried to discover why the chain wouldn't move.
My chainsaw is a Stihl Mini Boss 14" easy start.
