Re: [disklavier] Pedal problem Disklavier Mark IV (excessive heat)

2009-05-18 by Julien Roche

Thanks for your prompt answer !
I did again the LOUD PEDAL CALIBRATION
Result :
Loud stroke : 14,51mm
Stroke check : OK
Calibration : All OK
Result is the same : after 32mn now : box extremely hot and the pedal is switched off.
(I verified what is written on the back of the cover of the box : line G is same height as edge line F.
Line E, never goes higher than edge line F when the loud pedal is fully depressed.)
Maybe solenoids adjustments ?
Great thanks for your help !
Julien

The pedal should not need any extra cooling. You need to make sure that the pedal is properly set up (get your technician to check) and the solenoids need to be adjusted properly. Once everything is physically OK, you need to run the pedal calibration procedure from the Service Center. I have come across this several times, and every time it was down to the fact that the pedals haven't been re-calibrated after the lyre was re-attached.
