air present in the cylinder chamber (picture 2).
- Open the other bleed valve and move purged oil tank to the other side.
Holding the cylinder body in this position, turn the steering wheel as
shown in picture 4, until oil without air bubbles comes out of the bleed
valve. Then close the bleed valve.
