To any Doosan users on this site: If your company is still producing during this time and you require any service related assistance, please contact my cell number 973-803-9479 and we can guide you through some of the process related issues.
As I'm working with just our database, a serial number, electrical edition number (both found on the placard) and the ladder version (from the SYSTEM <TITLE> page) will provide the info needed to answer almost any question.
