WARNING Care of the ENVIRONMENT is the responsibility of all individuals and not that of someone else. If you love fishing, boating, or make your living from either, then please take good care of the sea and it's environment. HYDRAULIC OIL is NOT ENVIRONMENTALLY FRIENDLY and care should be exercised to prevent oil used during the bleeding process from running overboard, or into the bilge where it will be pumped into the sea. It only takes a little time and patience to protect the sea from further pollution. Please dispose of all waste oil, rags, plastic bags and other materials, thoughtfully and in a responsible manner. WE WISH YOU HAPPY BOATING!

Admiral HD Series - Installation Manual - Page 37 USING COPPER TUBING Helm Pump 5) P lace the flare in position against the fitting seat and slide up the nut and screw it on squarely so as not to cross the thread.
