4 Turn steering wheel from steering stop to steering stop NOTES 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.
IMPORTANT Slowly turn steering wheel from steering stop to steering stop until no more bubbles are ascertained in the expansion reservoir (30a).
IMPORTANT Repeat turning the steering from stop to stop several times (up to 30 times). During this process MB steering gear oil must be added to the expansion reservoir by an assistant.

5 Start engine without moving the steering IMPORTANT Allow engine to run for approx. 1 min at idle speed.
IMPORTANT During this process an assistant must observe the steering gear oil level in the expansion reservoir (30a) and add MB steering gear oil if necessary.
 
6 Turn steering wheel from steering stop to steering stop IMPORTANT When the engine is running, turn the steering wheel slowly several times from steering stop to steering stop, in the meantime refilling the expansion reservoir (30a) with MB steering gear oil.
IMPORTANT Repeat process until the steering gear oil level remains constant in the expansion reservoir (30a) and there are no more bubbles.
 
INSPECT Checking     
7 Check oil level in expansion reservoir (30a) and fill to maximum fill level IMPORTANT The oil level in the expansion reservoir (30a) must always be filled up to the maximum level.
