Rattling sound during Pan rotation

support

#1

Is it normal to hear a slight “rattling” sound when the Pan rotates - almost like the motor or gears are slightly loose? I have two of them, and one is slightly louder than the other. Is anybody/everybody experiencing this?

Edit: Today, the louder one has a slight squeal, a fraction of the way around, as it turns. Is it possible to “lubricate” the gears (carefully take it apart) without “voiding” the warranty? Or would carefully spraying a hint of WD-40 in the space between the round base and the main unit help?

Thanks!
