I have a N4400 and have had issues with it
I needed to move the fence so slaconed the bristol lever moved the fence , went to tighten only by hand and enough , The fence started movening to the left then the casting broke in two .
You could clearly see the casting was faulty , had a large area of slag / crystallisation in the casting .
Contacted Felder at Milton Keynes and was told the man I needed to speak with was away for a week , I said I need a replacment , Had to pay £90 plus postage to get one .
When the man who was away returned I phoned again and said I had a problem , I had allready sent the duff unit back and he had it with him . He asked " What do you want us to do ? " I replied replace the faulty unit please , He then said " So you want a replacement foe a saw that is 10 years old and is only a DIY / Hobby grade saw " I said are you sure ? this is a big saw with a 3HP motor 16amp , He was not intrested and basically ended the conversation saying " You sohoud think yourself lucky that we had a spare part for the 10 year old saw ,
Wow is this how they treat customers , The person I spoke with was the MD
Good job they did not build Tower bridge , I could see it falling in the river after 10 years .
