NOTA
Hold the cylinder body with the hand to prevent movements caused by the
air present in the cylinder chamber (picture 2).
- When the oil comes out of the bleed valve (without air bubbles), close the
bleed valve and continue to turn the steering wheel in the same direction
to fill the cylinder chamber (picture 3).
During this phase the cylinder body will move to the opposite direction up
to the end stroke.
- 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.
- Repeat the entire procedure to ensure the absence of air in the system.
