Question
I received this clock in 1993 as 25 yr service award from GM.
I no longer have the directions and cant remember how to adjust the chiming mechanism. it is off 1 hour and I know is a way to adjust that but cant remember how. Thank you for your advice

Answer
After the clock has struck an hour, move the hour hand to the time struck, then using the minute hand, set to the correct time.  The hour hand is friction fit to its shaft, you should have no problem making this adjustment.  A word of caution, if the hour hand strongly resists this action, stop at once and take the clock to a qualified repair shop.  Regards WJP
