DC POWER STEERING UNIT
The DC Power Unit is supplied with the autopilot pump set to “full
speed” This will give approximate 60 cu in/min of flow. To adjust
the autopilot speed, locate the adjusting screw (refer to Figure 15).
To reduce speed, turn adjusting screw counter-clockwise until the
desired autopilot speed is achieved.

It is suggested that after an
adjustment is made, the

Step 4 Autopilot Tuning

At this time verify oil level in the reservoir and wait approximately
2 minutes while the unit purges the power circuit.
17
If using front mount helms as shown in Figure 7, ‘burp’ each helm
station by loosening the fill cap just far enough to allow oil to
start escaping (do not fully remove cap). Use a rag to catch oil
spillage. DO NOT REMOVE THE FITTING. Tighten fill cap.
18 Exit purge mode by either pressing the purge button once, or
by cycling the power unit ignition power.
19 Verify oil level and replace fill cap.
With Power Unit on, confirm that the bleeding is completed by
counting the number of wheel turns from hard over to hard over.
Use chart on page 15 to determine the correct number of turns.
