Question
QUESTION: The clock is level, weights are hung correctly as per book facing it.  It will not chime . Clock keeps excellent time.
This is not a windup. I think It needs cleaning.  If i kind of move the little butterfly inside , it will chime on next event and thats it .  
Model 4505 cutting 8536

What kind of oil to use?
What kind of cleaner or solvent?
and what is the date of my clock?
Thank you very much in advance for you time.

ANSWER: heaviest weight goes on the right as you face clock. If pulling slightly and steadily on the right weight while moving the minute hand clockwise will not have it strike- then it is not cleaning it needs- advise what happens........

QUESTION: It still does not chime, but when the minute hand does pass
the hour,quarter hour, half past there is a click. There was some kind of part on bottom of the clock with the booklet, I don,t know if it belongs to the clock.  I am enclosing a closeup picture of this .Thank you again for you time

Answer
you said: " If i kind of move the little butterfly inside , it will chime on next event and thats it ."
-- it chimes properly on the next event? like the next time the hand reaches 3/6/9 or 12?? just like it is supposed to but then not ever again??

ok , if yes - after it performs properly, watch the butterfly as you turn the minute hand through the next 1/4 hour- does it move at all? does it start and turn -then stall?   

trying to determine with the above questions if your problem is with wear in the mechanism or a mechanical adjustment is needed.

the photo is of a piece of shipping packing that secures the pendulum leader behind the movement- not part of your problems here.

clock goes back to 1985 it seems- made by Hermle in Germany for ST
