Inspect the clutch pedal free play adjust as necessary.
Test the Hill-Holder on a grade of 3°or higher.
If the vehicle moves when the Hill-Holder is applied or the engine stalls
when the Hill-Holder is released:
Engine stalls: The Hill-Holder is releasing after the clutch. Loosen
the adjusting nut gradually until smooth starting and no stalling is enabled.
Vehicle slips backwards: The Hill-Holder is releasing before the clutch.
Tighten the adjusting nut so that the Hill-Holder is released after the
clutch engages.
WARNING
When adjusting the control cable nut be sure to prevent the cable from
turning.
