When the bleed valve begins to
drain oil completely free of air bubbles,
close the bleed valve and then continue
turning the steering wheel in the same
direction in order to fill the cylinder
chamber.
During this phase the cylinder body will
move towards the opposite direction until
the stroke end.

Open the other bleed valve and place
the container for oil recovery on the other
side. Holding the body of the cylinder in this
position, slowly rotate the steering wheel
as shown in the figure, until the bleed valve
only spills oil completely free of air bubbles.
Finally, close the bleed valve.

Repeat the procedure again in
order to ensure the complete absence of
air inside the circuit.
WARNING
It is very important to make sure that the air is completely purged from the system before
using your boat! We recommend to try manually move the motor towards port and starboard,
paying attention to any movement of the cylinder body on its rod.
If the cylinder body moves for more than 15mm (1/6 inch), it means in the system there is still air
to be purged. The presence of air in the system can lead to incorrect controls, with the consequent
risk of damage, injury or death.
