Note: Lock button and Compression spring 3 will fly away in this step.
Be careful not to lose them.

the lever is located within the area B (Fig. 8). Change lever can now be
pulled off. Remove O ring 17 from Change lever (Fig. 9).
ASSEMBLING
1) Apply grease to O ring 17 and the pins of Change lever as described in page 3.
2) Put Compression spring 3 and Lock button in place on Change lever. Assemble Cap provisionally to Change lever

lever installation hole. Change lever cannot be inserted completely in this step.

Lock button pressed.
