After first time out, trimmer began shaking violently in my hand. Performance did not diminish, but it got to the point where I needed to take frequent breaks (every minute) just to finish. Problem seems to be coming from the motor.

One of your strings probably broke off inside of the trimmer head. If so, take off the head and restring the trimmer.

Either what Henry said or it sounds like you bent the motor shaft. But unlikely cuz that shaft being bent would shatter the motor probably.

It would be nearly impossible to bemd the motor shaft as the motor is in the head of the trimmer.

Henry.... The shaft could still be bent in the head. Im aware that the motor is at the bottom. It would have taken a hell of a hit to do it..... More likely a string is missing from one side. But I've had that and it wasn't really violently shaking.

In addition to the above, you could try narrowing down the problem by:

1) run the trimmer without any line, if it still vibrates, then:
2) remove the lower black base and spool
3) last thing you can remove is the other half of the spool, but you'll need a socket for that

Once you get to #3, you can also try running the trimmer, and if the shaft is bent you should be able to see it then.
