8. Refill your steering system from the
highest reservoir.
9. Adjust the bleeding screws so that the
cylinder will be bled when the rod is
extended in the original direction.
Generally, you close the bleeding screw
or nipple closest to the now retracted
rod. Open the bleeding screw closest to
the rod that is now extended.
10. Use the Controller to fully extend the
cylinder rod to the other side.
11. Refill the highest reservoir.
12. Repeat steps 6 to 10 at least 10 times.
13. Close all bleeding screws or nipples.
Clean up any oil spills and wipe fittings
clean. Remove any buckets or
equipment a short distance from the
cylinders and fittings.
14. Use the Control Unit to extend the rod
fully in one direction and then the other.
15. Check for leaks by looking for spilled
hydraulic fluid on or near fittings and
cylinders.
16. Check that a hardover to hardover time
of 10 - 15 seconds can be attained with
your drive unit.
17. Return to Step 7 of the Set-up Routine.
**** IMPORTANT ****
If you have installed a ComNav Marine reversing motor pump, a constant running pump or an
engine driven pump, there are several checks that must be done during the first several weeks of
usage in order to prevent poor or dangerous steering performance. During this period you must
check for air or leaks in your hydraulic system.
Residual air in your steering system
Following the initial installation and bleeding of your ComNav pump, some residual air may remain
suspended in the hydraulic fluid. During the first few weeks, this air will gradually bleed out through
the header tank or the highest helm pump and the oil level may go down. Check several times and
add more oil as required.
Leaking fittings or equipment
Following the initial installation and bleeding of your ComNav pump, continuously monitor the oil
level of the reservoir, or the highest helm pump in your steering system and add oil as required. If
this condition persists, it may be an indication of leakage in your steering system. Check all
hydraulic steering fittings and equipment for leakage.
