	Draining
	General notes for working on vehicles with level control/ADS	All models with Code 216b, 216c, 217a, 480	AH32.00-P-0002-01A
1	Detach connecting rod or connecting linkage (7) from level controller lever (arrows)
1.1	Remove linkage rod for suspension-control module/torsion bar at ball joint	Model 203.2
2	Detach torsion bar connecting rod from torsion bar	Model Series 202, 208	AR32.30-P-0630-01A
	Press torsion bar up	Improves access to drain plug in suspension-control module (3p)
3	Attach oil drain hose (061) to oil drain plug (3p) on level controller (3)	Model Series 140, 210, 203.2 at connection "S2" Model Series 202, 208 at connection "A" Note technical modifications on Model 140 with ADS ↓
	Level controller oil drain plug	Model Series 140 with ADS starting 01.10.92	BT32.30-P-9209-01A
	Risk of injury to skin or eyes from hydraulic fluid spraying out under pressure. Risk of poisoning from swallowing hydraulic fluid.	Release the pressure in the hydraulic system completely before starting any work on the system. Wear protective clothing and safety glasses.	AS00.00-Z-0013-01A
4	Open oil drain plug (3p) slowly and collect the oil in a clean container	The oil collected can be re-used.
	Close oil drain plug (3p) again		*BA32.30-P-1002-03A

6	Push level controller lever to "Fill" position (F)
	Risk of accident. Accidents may result if the vehicle starts off unintentionally with the engine running. Risk of injury as working around the engine during start-up or while running may result in contusions and burns	Secure vehicle to prevent it from moving. Wear closed and snug-fitting work clothes. Do not grasp hot or rotating parts.	AS00.00-Z-0005-01A
7	Start engine and run at moderate speed for approx. 60 seconds	The system bleeds itself automatically. Installation: Ensure that there is sufficient oil in the reservoir. The pump must never be allowed to draw in air.
	Switch off engine
8	Push level controller lever into the "Empty" (E) position.	The suspension lever must remain in this position for 60 seconds.
9.1	Connect linkage rod or relay linkage (7) to suspension-control module lever (arrows)	MODEL 140, 202, 208, 210 Replace self-locking bolts and nuts.
9.2	Connect linkage rod for suspension-control module/torsion bar at ball joint	Model 203.2
10	Place the vehicle on its wheels and push it up and down firmly several times	The vehicle level adjusts itself.
11	Check and correct oil level in oil reservoir	MODEL 140, 202, 203.2, 208	AP32.30-P-3211BA
