11) Depress and release the clutch pedal two or three times to ensure that the clutch pedal and release lever

operate smoothly. If the clutch pedal and release lever do not operate smoothly, bleed air from the clutch hy-

draulic system.

12) Measure the clutch pedal full stroke length again to ensure that it is within specifications. If it is not within

specifications, repeat adjustment procedures again from the beginning.
