WARNING: DO THE DEACTIVATION PROCEDURE TO PREVENT THE OPERATION OF THE
_______ THRUST REVERSER. THE ACCIDENTAL OPERATION OF THE THRUST REVERSER CAN CAUSE INJURY TO PERSONS AND DAMAGE TO EQUIPMENT.
(5) Do the deactivation procedure for the thrust reverser isolation valve (AMM 78-31-00/201).
NOTE: Do not install the ground deactivation pins in the thrust
____
reverser sleeves.
S 865-035-N00
CAUTION: DO NOT EXTEND THE THRUST REVERSER IF THE CORE COWL PANELS ARE
_______ OPEN. DAMAGE TO THE THRUST REVERSER AND CORE COWL PANELS COULD OCCUR.
MAKE SURE THE AREA AFT OF THE THRUST REVERSER IS CLEAR OF ALL EQUIPMENT, WORKSTANDS, ETC. DAMAGE COULD OCCUR IF THE THRUST REVERSER CONTACTS THE EQUIPMENT.
WHEN YOU MOVE THE THRUST REVERSER MANUALLY, LOOK FOR LOWER ACTUATOR OPERATION, OR LOWER AND CENTER ACTUATOR OPERATION. IF YOU SEE THIS OPERATION, STOP AND LOOK FOR BROKEN FLEXSHAFTS.
(6)
Make sure that the core cowl panels are closed and latched.
S 725-036-N00
(7)
Turn the manual drive mechanism on the sync lock with a 3/8 inch square drive in the correct direction to try to extend the actuator.
NOTE: A torque value of 45 inch-pounds should be sufficient to move
____ the thrust reverser sleeve. However, excess torque is acceptable because of the clutch mechanism in the sync lock which will prevent overtorquing of the manual drive.
S 725-037-N00
(8) Make sure that the actuators do not extend.
(a) If the actuators extend, replace the locking hydraulic actuator (AMM 78-31-17/401).
