CAUTION
These instructions show how to fill and purge a SeaStar Steering
System with the P/A unit installed. The same steps apply to ALL
cylinders with the exception of which bleed fitting to open and close
and the direction the cylinder rod moves. These variations are
shown in inset diagrams at each step. For multiple steering stations,
star t with the lowest station while going through Steps 1 – 7,
repeat at each higher station until complete.
DO NOT turn ON P/A unit until manual portion is completed.
This procedure requires two people. One person may not be able
to remove all the air from the system, which will result in spongy,
unresponsive steering.
During the entire filling procedure, oil MUST be visible in the filler
tube. DO NOT allow oil level to disappear into the helm pump, as
this may introduce air into the system and increase your filling time.
2 bottles (2 quar ts or liters) for single station and single cylinder
systems. One additional bottle for each cylinder, helm, and or
autopilot added to the system.
Oil can be re-used if filtered through a fine mesh screen such as
that used for gasoline. If unable to filter oil, an additional bottle of
fluid is required.
"Bleeder" refers to cylinder or P/A unit fitted with bleed fittings.
Bleed fittings can be opened by unscrewing bleed nipple nut two
turns.
Protect your boating environment by ensuring that all used oil is
disposed of properly.

NOTICE
BEFORE bleeding the main steering system (helm, hoses and
cylinders), the RETURN line will need to be purged.
Removing Air From Return Line
• Install the fill tube and fluid fill bottle into the helm pump.
Filling the helm full of fluid prior to connecting the filler tube and oil
bottle will decrease purge time.
• Open the manual bleed valve (see Figure 10) and reser voir bleed
fitting (see Figure 10) on the power assist unit. The manual bleed
valve should be opened two full turns.
