1. Prepare dial cord and tension spring as shown bellow.
2. First place the drum in such a position as it provides a minimum capacitance for tuning gang.
Hook a free end of the spring to the drum and thread the cord as shown by starting from No. 1 through No. 8.
Please give if four-turns around a tuning shaft at No. 2.
Pass it through No. 3 & 4, and hold it temporarily at No. 5.
Fit the other end No. 8 of the cord two turns in the arrow direction around the drum and finally.
