New to woodworking and Lumberjocks.
Trying to figure out what’s going on with my new Ridgid R4512, (only 35 days old used only on a few small projects)
After running great for weekend projects over the last thirty days it suddenly started making a “loud” squeal on startup. This is a high pitched chatter or whine that last one to two seconds then the saw runs quite as usual.
I did a search on numerous sites and followed the advise offered for this type of problem: checked the belt, re-tightened the belt, used belt dressing, checked the arbor for free movement with out the belt, checked the bolts/washers holding the blade…
While checking the saw I began to rotate the blade rotating it back and forth several inches in each direction. I moved the blade around the different points of the blade so I could rock it back and forth around the whole rotation of the blade.
What I found was that at one point on the blade, as I rotate the blade rapidly back and forth there is a metallic grating sound. At first I was sure there was something rubbing against the blade as it sounds like a metal on metal scraping sound. I checked and the blade is completely free and clear…
I don’t know if this metallic sound is normal or, is this what’s causing the screeching on startup…
Any thoughts or help would be greatly appreciated. For what it’s worth the saw works great. Cuts like a champ. I just don’t know if the sounds foretell of a problem or not.
I can always return the darn thing to HD but seeing as how I’ve added a router table and modified the wings to just were I want them I’d rather not repeat all that work if anyone has a thought on the problem.
