Wish you well with your new machine! Had my 4003 for many years now (well before there was a 4003G). It has given good service and I've learned to produce accurate work on it. As for those not recommending tearing down that new machine, I highly recommend it on any value import. Tore my new 4003 down while still partly on its shipping box to clean and inspect everything before ever considering putting power to it. They may be better at prepping today but there was lots of casting crud and rough places in my machine. It needed to be thoroughly cleaned inside, contact areas needed dressing with a stone or file, a few fits on the cross-slide and compound were given minor scraping (was close enough to ware down with time but I wanted a true and solid contact surface) and there was a lot of de-burring done before reassembling the machine. Then came the testing but, to my amazement, there were no issues there; better than I expected from China and surprising considering the rough finish of the machined parts (body filler and paint conceal the true finish of the exterior on my machine). Powered it up and started making chips. With what I found from the factory in my machine, not surprised your hearing strange sounds if it wasn't gone though thoroughly before hitting the on switch. I have no regrets in purchasing the 4003, it is a great machine for the money and Grizzly has shown itself to offer equipment worth considering for home shop machinists.
