AF 561 Diesel Horn Billboard

Instructions for 561

Brady...   Thanks for the attachment.  Are these the 'operating' instructions, or are they only service instructions?  If I google A/F 561 Horn Images, there are some instruction sheets among the images. unfortunately, I have not been able to expand these into a readable image of the detailed instructions.   That's probably my lack of 'geekiness'.

However, the images do not look like the cover sheet of your instructions....which leads me to believe there's an operating instructions sheet that talks about that shaft.  Yes?  No?

Thanks, though for your help...I'm saving your info.

KD,

You're right, that's from the maintenance manual, but it does talk about adjusting the volume and tone of the horn and the diagram shows you where the adjustment screw is. There doesn't appear to be a knob.

My 1949 Instruction Manual pre-dates the 561, and Tom Barkers repair guide doesn't seem to cover the 561.

Anybody out there got a copy of the 561 instruction sheet?
