If you do not have the manual you can get it at manualslib.com. I looked at the manual for a R4512 and it shows the 5 screws you mentioned. Those should be what you need to turn to level the plate. Did you buy the saw new or secondhand? If secondhand perhaps the previous owner replaced the originals with screws that are too short.
