Failure to comply may result in injury to personnel. Maintain engine rpm at 1,250-1,450 rpm while performing pressure and flow tests. Failure to comply may result in damage to equipment. HYDRAULIC FLOW AND PRESSURE TEST CAUTION WARNING (1) Position drain pan under winch control valve. (2) Disconnect pump supply pressure hose from pressure port (P) on winch control valve. (3) Connect pressure hose to hydraulic tester. (4) Connect pressure hose from hydraulic tester to pressure port (P) of winch control valve. (5) Completely open hydraulic tester load valve. (6) Start and run engine until normal operating temperature is reached (TM 9-2320-365-10). (7) Engage PTO (TM 9-2320-365-10). (8) Increase engine rpm to 1250-1450 rpm (TM 9-2320-365-10).
