	Adjusting
	Ignition: OFF
1	Inspect connecting rods (32/4, 32/9) and accelerator control cable (30) to ensure they operate freely and are in proper condition	Replace parts if necessary
2	Check play between driver spring (30/7) and guide piece (30/5), adjust	There must be play between driver spring (30/7) and guide piece (30/5). Set with adjusting screw (30/3), if necessary	*BE30.10-P-1001-01A
3	Remove, install resonance flap		AR09.20-P-1791D
4	Loosen clamping bolt on connecting rod (32/9)
5	Press transfer lever (32/14) forwards using large screwdriver	Against the spring force in the actuator
6	Tighten clamping bolt on connecting rod (32/9)
7	Detach connecting rod (32/4) at one end and check closed throttle position (idle) stop	The bell crank (32/5) must be resting against the closed throttle position (idle) stop of the idle speed control actuator.
8	Attach connecting rod (32/4) free of tension	The connecting rod (32/4) must remain set to a fixed size. Measure between centers of ball sockets The adjustment of the connecting rod (32/4) must be performed very accurately. The microswitch for the idle speed control must be operated when doing this (closed)	*BE30.10-P-1002-01A
9	Idle speed adjustment at engine end  Check setting of control lever (32/7), adjust	Engine 104:  The roller (32/8) in the control lever (32/7) must be resting free of tension against the end stop of the fulcrum lever (32/6). Adjust fulcrum lever (32/6) with connecting rod (32/9), if necessary, so that the roller (32/8) is resting free of tension against the end stop
10	Adjust control pressure control cable (98)	With control pressure control cable attached, turn adjusting screw (98/2) until the tip of the drag lever (32/2) is at the same level as the tip of the fulcrum lever (32/6)
11.1	Checking full throttle stop, adjusting	Manual transmission:  With engine switched off, depress accelerator pedal (24) to full throttle stop. Bell crank (32/5) must be resting against full throttle stop of idle speed control actuator. Release variable full throttle stop (38), if necessary, by turning to the left. Pull out stop pin slightly, lock full throttle stop (38) in position by turning to the right.
11.2		Automatic transmission:  With engine switched off, depress accelerator pedal (24) to full throttle stop at kickdown switch (S16/7) (do not operate kickdown switch).  Bell crank (32/5) must just be resting against the full throttle stop of the idle speed control actuator; set with adjusting screw (30/3), if necessary
12	Checking idle speed adjustment at chassis end, adjusting	Accelerator pedal (24) in idle speed position. There must be play between driver spring (30/7) and guide piece (30/5); adjust from inside car with adjusting nut (30/2), if necessary
13	Grease accelerator control cable (30) between end piece and guide piece (30/5) with anti-corrosion grease		*BR00.45-Z-1006-06A
