Important Note
When dealing with any hydraulic system great care must be taken to
ensure that a high degree of cleanliness is observed and no dirt, moisture
or foreign objects are allowed to enter the system. Only the recommended
fluids must be used. Use Q8 DYNOBEAR or equivalent (10cSt at 40° C).
Drain the steering system from the lowest point, usually at a cylinder
coupling.
Fit T-pieces into the port and starboard delivery lines, couple the lines to
the appropriate service ports of the pump using flexible hydraulic hose.
Couple the reservoir port to the reservoir/balance line from the helm units.
A low pressure, transparent plastic tube can be used. Ensure that this line
rises gradually with no down turns.
Refill the steering system as recommended by the manufacturer, using
clean hydraulic fluid.
Fill the cylinder by temporarily removing the cylinder couplings and
hoses at each end, refit the hoses securely.
Starting at the highest helm unit, fill the helm reservoir.
Slowly turn the steering wheel two turns to port and then to starboard,
checking the level of fluid in the helm unit reservoir at all times.
Next, turn the wheel fully in one direction until a slight pressure is felt,
continuously monitor the reservoir level.
Repeat in the opposite direction and continue in this manner until topping
up is no longer necessary.
When satisfied that the steering is fully bled manually, apply power to the
pump unit.
Turning the wheel fully from lock to lock will cause the pump to self-
purge.
