2-4-3. When the Adjuster Assy Is Returned

by the Emergency Mode

When the Adjuster Assy is returned by the Emergency
mode, it results in the state that the Stopper of the mecha-
nism has moved out from its correct mechanical position.
Therefore, be sure to replace Adjuster Frame Assy.
The Stopper alone cannot be replaced because the Stopper
got accustomed to move out from its correct mechanical
position easily.

from its correct position to the front,
it causes the Emergency state.
