1. Changes to the Board
As the motor is changed, the main board is to be changed from the board with the suffix No.-11 or -12 to the board with No.-21. When only replacing the motor or main board by a new part, replace the appropriate components on the main board. (For details, refer to â2. Replacing the Board/Motorâ on page 4.)
