Bleeding The Steering System

1. After installation is complete, raise the vehicle so that the wheels are no longer touching the ground.
2. Open engine cover, lid and reservoir.

3. Fill reservoir up to the MAX mark, until the level no longer drops.
4. Then turn the steering to the left and to the right. Hold the steering on full lock for approx. 30 seconds on each side until the level no longer drops. Continually check the fluid level and fill to the MAX mark again if necessary.
5. Lower vehicle onto wheels. Briefly start the engine, let it run for approx. 1 second and add Pentosin again. This procedure causes the fluid level in the reservoir to fall rapidly, so constantly add more Pentosin CHF 202. The reservoir must not be sucked dry.
6. If the fluid level in the reservoir does not fall any further when the engine is briefly turned over, start the engine and let it run at idling speed.
7. Turn steering on full lock several times to left and right at idling speed and observe the fluid level during this procedure (second worker required). If it continues to fall, add fluid until the level in the reservoir remains constant and no more air bubbles circulate in the reservoir when the steering wheel is turned.
8. Switch engine off and set the correct fluid level. This must be between the MAX and MIN markings.

When the correct level has been reached, no air bubbles must be circulating in the reservoir and the fluid level must no longer drop.
