In what way? The arms not moving up and down properly?
If you have the time, you can put one or two drops of silicone shock oil or put some graphite grease on the pivot pins so that you get a smoother action. Else, like what you say, you can let the parts settle down properly by running a few tanks.
The final thing for you to do is PICTURES !
