WARNING:
BE CAREFUL WHEN YOU DO WORK ON THE ENGINE AFTER SHUTDOWN. THE ENGINE CAN STAY HOT FOR A LONG TIME. IF YOU DO NOT OBEY THIS INSTRUCTION, INJURY CAN OCCUR.
WARNING:
ALWAYS USE APPLICABLE GLOVES TO TOUCH HOT PARTS. HOT PARTS CAN CAUSE INJURY TO PERSONS.
WARNING:
MAKE SURE THAT THE THRUST REVERSER DOOR IS SUFFICIENTLY SUPPORTED DURING REMOVAL OR INSTALLATION. THE THRUST REVERSER DOOR WEIGHS APPROXIMATELY 775 LBS (351 KG). IF IT IS NOT SUFFICIENTLY SUPPORTED, INJURY TO PERSONNEL AND/OR DAMAGE TO THE COMPONENTS CAN OCCUR.
WARNING:
REMOVE OR INSTALL THE THRUST REVERSER DOOR INDOORS. IF YOU CANNOT DO IT INDOORS, YOU CAN REMOVE OR INSTALL THE THRUST REVERSER DOOR OUTDOORS BUT ONLY IF THE WIND SPEED IS LESS THAN 23 MPH (37 KM/H).
IF THE WIND MOVES THE THRUST REVERSER DOOR, INJURY AND/OR DAMAGE TO EQUIPMENT CAN OCCUR.
CAUTION:
YOU MUST NOT LET HYDRAULIC FLUID FALL ON THE ENGINE. UNWANTED HYDRAULIC FLUID MUST BE REMOVED IMMEDIATELY WITH A CLEAN LINT- FREE CLOTH. THE HYDRAULIC FLUID CAN CAUSE DAMAGE TO THE SURFACE PROTECTION AND SOME PARTS.
CAUTION:
THIS PART IS A REMOVABLE STRUCTURAL COMPONENT (RSC), WHICH CAN BE MOVED BETWEEN AIRCRAFT. THUS IT CAN HAVE DIFFERENT OPERATION CONDITIONS AND A DIFFERENT LIFE RECORD (FLIGHT HOURS/FLIGHT CYCLES/CALENDAR) FROM THE AIRCRAFT IT IS INSTALLED ON OR REMOVED FROM. THE OPERATOR IS RESPONSIBLE FOR THE SPECIFIC TRACKING AND CONTINUED AIRWORTHINESS OF REMOVABLE STRUCTURAL COMPONENTS. INCORRECT MAINTENANCE OF THESE COMPONENTS CAN CAUSE A RISK FOR THE FLIGHT SAFETY.
