Determining the condition

I read the manual while testing the organ.

A lot of the functions seem not to be working :

• Half of the keys do not sound at all
• The volume pedal does not work, the organ sounds only at the loudest level
• A lot of crackling and bad contacts
• Register groups are not working correctly
  

It isn't even possible to get a clear overview of what is working and what is not.
I decided to take it step by step.
Seems to me it is best to start with cleaning the key contacts. It is not possible to determine the register groups are working when the key contacts are bad.

In the service manual are some instructions on how to open up the organ. They seem not to be complete. There are different versions of the eminent 310. The service manual probably had to be universal. I had to search for the proper order, and the right screws on opening it up. On the photograph you can see the fully opened up position.
