The attached picture shows the function of the HiShift
clutch and the influence of the adjustment. The curve
shows the clutch pedal position according to time.
--- The clutch pedal is up ( 1 )
--- The HiShift push button is pressed, the clutch pedal
goes down quickly ( 2 )
--- The clutch pedal is down, the desired changing
movement is completed ( 3 )
--- The push button is released, the clutch pedal rises
quickly to the point when the clutch begins to engage
(knee point), this point has been preset in the factory (
4 )
--- If the speed is below 4 km/h then the pedal rises slowly
(lower curve) ( 5 )
--- If the speed is more than 4 km/h then the clutch pedal
rises quicker (the upper curve) ( 6 )
