Query: Nylon Ring Gear Breaks

I used this saw to cut down two live junipers when I got it about eight months ago which work just fine. Then I used it to cut up a dead oak tree, the chain bind in the log, which broke some of the nylon plastic ring gear teeth. Now the motor spins, but if the ring gear does not catch the chain will not. I tried to use the warranty to fix it but so far they say it was due to abuse. This is a powerful saw but if you are thinking for long term use, this saw is not it. This saw is for very light duty work only and will not last for more than a couple of years use, even for light duty cutting, becuase the gear is made of plastic. Even though this saw is inexpensive, I could have taken that money and rented a more heavy duty saw.
