Terry, On new pianos at the dealer's store, you probably should check to see if the plate screws/bolts are tightened since these are straight from the factory. As with everything else in new pianos, adjustments are necessary. The supply houses sell these tools. Tighten them just enough to be snug but not so tight that you might strip the screw holes. On in-home pianos, I would be careful about tightening them. Just remember that at the times when humidity is high, the wood has swollen. When the humidity is low, the wood has contracted. It's better for these screws/bolts not to be too tight nor too loose. Always remember to allow for those humidity changes. I don't tighten in-home pianos except when I find instability problems. Then I check the plate bolts. If they are loose, by that I mean they need than just a slight turn, I will tighten them. But never too snug.

As a newbie working as a floor tuner, I currently service mostly new pianos, but trade-ins, and home tunings will bring me in touch with older pianos as well. I want to make sure I follow the correct and best method for doing this, so I can avoid big problems.
