	Adjusting
2	Wide open throttle  With engine switched off, depress accelerator (24) until relay lever (31/1) is resting against wide open throttle stop (b).	Do not operate kickdown switch (S16/7).  Hand-Held Tester must indicate 100 %. See Diagnosis Manual Diesel Engine Volume 1.1 Index A2/A3. Turn adjusting screw (32/3) until relay lever (31/1) has reached wide open throttle stop (b).
3	Closed throttle position  The relay lever (31/1) must be resting against closed throttle stop (a).	Hand-Held Tester must indicate 0 %. See Diagnosis Manual Diesel Engine Volume 1.1 Index A2/A3. Turn adjusting nut (32/2) until relay lever (31/1) has reached closed throttle stop (a).
4	Control pressure bowden cable  Alter position of connecting rod (31/4) by turning the hexagon bolt (31/5) so that the tips of the bell crank (31/7) and of the drag lever (31/6) are opposite each other.	The length of the connecting rod is measured between the ball socket centers.
5	Vacuum control valve  Detach bowden cable (32) at the relay lever (31/1) by pressing off the ball head. Slacken nuts (65/1). Press relay lever (31/1) onto wide open throttle stop.	This move the vacuum control valve (65) into the starting position. Turn vacuum control valve (65) clockwise until a resistance is felt. Tighten nuts (65/1) in this position.
