When I buy a saw, even a parts saw, if something is not disclosed or pictured to where I could tell there was something seriously wrong, I immediately contact the buyer through the ebay email system and calmly explain the problem and how there was no way from the description or pictures to know that it had the problem. I've found that if I ask them how we could find a solution, many if not most will agree to make an equitable partial refund, or allow a return of the saw. Always give the seller the benefit of the doubt and allow them to show their true colors. I've met some outstanding sellers with this approach, some of whom I have bought from again. Never start off adversarial. If they refuse to make it right, my final words are "No problem, we'll let ebay decide." That always ends the stalemate.
