_______ OPEN POSITION EXCEPT WHEN YOU LOWER THE COWL. IF YOU LEAVE T THE VALVE IN THE OPEN POSITION, THE ACTUATOR FLUID CAN CONTINUE TO DRAIN OUT OF THE ACTUATOR INTO THE PUMP. THIS CAN REDUCE THE SNUBBING ACTION OF THE ACTUATOR WHEN YOU CLOSE THE COWL. REDUCED SNUBBING ACTION CAN CAUSE INJURY TO PERSONS AND DAMAGE TO EQUIPMENT.
(i) After the reverser half is held by the locked reverser opening actuator, close the valve on the hand pump.
CAUTION: DO NOT DISCONNECT THE HAND PUMP HOSE FROM THE REVERSER
_______ OPENING ACTUATOR WHILE THE HOSE IS PRESSURIZED. A SPRAY OF OIL CAN COME FROM THE HAND PUMP HOSE IF IT IS DISCONNECTED WHILE PRESSURIZED.
