Document adapted to the revised procedure

 	Remove/install
Danger!	Risk of injury to skin or eyes caused by hydraulic fluid spraying out under high pressure. Risk of poisoning caused by swallowing hydraulic fluid	Depressurize the hydraulic system completely before starting any work on the system. Wear protective clothing and safety glasses.	AS00.00-Z-0013-01A
 Danger!	Risk of injury caused by fingers being pinched or crushed when removing, installing or aligning hoods, doors, trunk lids, liftgates or sliding roof	Keep body parts and limbs well clear of moving parts.	AS00.00-Z-0011-01A
Danger!	Risk of death caused by vehicle slipping or toppling off of the lifting platform.	Align vehicle between columns of vehicle lift and position four support plates at vehicle lift support points specified by vehicle manufacturer.	AS00.00-Z-0010-01A
1	Hoist vehicle with lifting platform until wheels are free
2	Remove cover of charge air manifold together with cover above power steering pump	Model 220.025/125/ 026/126
	Fill
3	Fill the expansion reservoir (2) of the power steering to approx. 10 mm below the upper wedge of the container with MB steering gear oil	 Do not start the engine! If the engine is started there is a risk of air entering the hydraulic steering system, which is then extremely difficult to remove.
		 Fill the expansion reservoir (2) to approx. 10 mm below the upper edge of the reservoir with MB steering gear oil.
		 Refill with MB-steering gear oil continuously until the oil level remains constant.

		 Model 210 with level control	*BF32.30-P-1001-01A
	Bleeding
4	Turn steering wheel from steering stop to steering stop	 Do not start the engine! If the engine is started there is a risk of air entering the hydraulic steering system, which is then extremely difficult to remove.
		 Turn steering wheel slowly from steering stop to steering stop until bubbles are no longer visible in the expansion reservoir (2).
		 Repeat turning the steering from stop to stop several times (up to 30 times). During this process, MB steering gear oil must be poured into the expansion reservoir (2) by a second person.
 Danger!	Risk of accident caused by vehicle starting off by itself when engine is running. Risk of injury caused by contusions and burns during starting procedure or when working near the engine as it is running	Secure vehicle to prevent it from moving by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts.	AS00.00-Z-0005-01A
5	Start engine without moving the steering	 Allow engine to run for approx. 1 min at idle speed.
		 During this process, a second person must observe the oil level in the expansion reservoir (2) and add MB steering gear oil if necessary.
6	Turn steering wheel from steering stop to steering stop	 When the engine is running turn the steering wheel slowly several times from steering stop to steering stop, meanwhile adding MB steering gear oil in expansion reservoir (2).
		 Repeat the procedure until the oil level in the expansion reservoir (2) remains constant and bubbles are no longer visible.
	Checking
7	Check oil level in the expansion reservoir (2) and fill up to the maximum fill level
	Power steering - checking and correcting oil level	Model 202 up to 31.8.95	AP46.00-P-4611BA
		Model 202 as of 1.9.95, model 129, 163, 170, 208, 210, 220, 230	AP46.00-P-4611BB
8	Test run engine and check that steering system is not leaking and is functioning correctly	 If leaks are found, determine the cause and rectify, subject to separate repair order.
9	Install in the reverse order
