This is my first time on here . so bear with me Please . I have a Homelite Model#4620c that is like brand new . The saw starts and runs great with the exception that after only 2 cuts threw a 10" oak it gets so hot you can't hold you hand on the top cover . I bought this saw for resale purposes and don't want anyone to get junk . My question is why would this saw heat up so quickly and what can I do to fix it ? Any help would greatly be appreciated . Thanks
