DJUSTING THE KEY CLAMP SPRING
Because keys may vary slightly in thickness, you may need to
occasionally adjust the key clamp spring to make sure that keys are
properly clamped in the key carriage.
If your key is either difficult to insert or too loose to clamp into place,
perform the following steps.
To adjust the key clamp spring:
1. Gripping the key clamp knob, pull the key carriage completely
forward.
2. Raise the key clamp spring by turning the key clamp knob
counterclockwise, as shown in Figure 3.21 (for left-handed
combinators, turn the key clamp knob clockwise).
3. Slide a key blank into the key carriage.
If the key is difficult to insert, go to Step 4a.
If the key is too loose to clamp in place, go to Step 4b.
