Not sure if you remember but around November December last year my husbands EX16 started knocking and we had no idea where it was coming from. After the New Year we started looking again till in the end we gave up. Anyway on Saturday we were talking to a fellow who gave us an address to take it to, well in less than 24 hours and lots of grey hair latter he found what the course was..........it was the bellows. Yes that's right. When the arm came down the bellows were suctioning down and banging when releasing when the arm was coming up. Now Terry's saw is quieter than mine. Thanks for all of your help and suggestions, we did appreciate them.
