Use this procedure if air has entered the hydraulic system
or if it has been dismantled.
Important! Use only the recommended hydraulic fluid – see page 8.
Before commencing ensure that any containers are clean and free of
contamination. Please dispose of any waste fluid and materials
responsibly.
Danger of entrapment! - Keep clear of moving steering components and
linkages at all times.
Procedure:
Assemble the drive with pump, hoses, reservoir and install. Except –
Do not connect the motor to the course computer
(the pump is not used to bleed the system).
Do not connect the ram to the quadrant.
1) Engage the clutch by turning the autopilot on (refer to the Autopilot
manual).
2) Fill the reservoir and turn the tap on.
3) Loosen the reservoir hose at the ram (but do not disconnect it).
Fluid will emerge, tighten when all air bubbles have gone, top up the
reservoir
4) Remove A and B hoses from the pump and place the ends in a
container of fluid.
5) Slowly pull and push the ram fully in and out ensuring the ends
remain immersed until all air has been expelled.
6) With the ram in mid position, reconnect A and B hoses to the pump.
Check the reservoir level and top up if required.
7) Turn the autopilot off.
8) Reconnect the motor to the course computer and the ram to the
quadrant.
The Drive is now ready to run. If it initially fails to respond to the
autopilot correctly use the wheel to assist by turning in the same
direction as the ram. This will move any air trapped in the pump.
Note. If the drive uses a constant running pump remove the hose and
fitting from the reservoir port, fill and replace the fitting and hose before
point 3) above.
