Re: G-5400B maintenance - Warning

If you suspect a dirty or worn Potentiometer, then take care to either  
switch the rotator off every time you leave the station or better still replace  it 
The reason is, that if the rotator starts hunting, back and forth, trying  to 
find the proper (set) direction you will probably exceed the time that the  
motor can operate without overheating!
This could result in a burnt out motor and an expensive  replacement.
How do I know this? Well it happened to me!  Fortunately I do keep a  second 
(spare) rotator so I was only off the air for a  short time.
