I have had my saw (model 4000) about 2 years and have had no major problems at all until recently. It seems the fence has become more loose than normal. When I move it using the front locking handle, the rear of the fence is very loose and moves a considerable distance before being locked in place which throws off my measurements and I have to keep readjusting to get it set where I need it.
I have adjusted the rear screw tighter but it then tightens so much it rocks the fence off 90 degrees to the table. Anything looser and it won't stay on my mark because of the rear of the fence moving so much. When it is locked down it sometimes moves toward or away from the blade and will bind the wood between the fence and blade. Can the fence be rebuilt or am I not adjusting it right? Thanks for any help that you can give me.
