WARNING:_______ DO NOT PUT GROUND EQUIPMENT UNDER THE WINGTIPS DURING THE FUELING OPERATION. THE WINGS MOVE DOWN UNDER THE WEIGHT OF THE FUEL AND THE WINGTIPS MOVE THE MOST. BECAUSE THE FUEL TANKS ARE VENTED THROUGH THE WINGTIPS, A DANGEROUS AND EXPLOSIVE MIXTURE AROUND THE WINGTIP CAN OCCUR.
DO NOT OPERATE THE HF COMMUNICATION SYSTEM OR THE WEATHER RADAR DURING FUELING OPERATIONS.
IF A FUEL LEAKAGE OCCURS DURING REFUELING, DO NOT DO THE APU SHUTDOWN PROCEDURE. SUDDEN SHUTDOWN OF THE APU WHILE IT IS ON, CAN CAUSE A PRESSURE SURGE OF BURNING GASES OUT OF THE APU. THE BURNING GASES CAN CAUSE A FIRE OR EXPLOSION.
DO NOT START OR STOP THE APU DURING THE REFUELING OPERATION. AN EXPLOSION CAN OCCUR.
CAUTION:_______ DO NOT USE MORE THAN 55 PSI FUEL PRESSURE AT THE FUELING NOZZLE. IF YOU USE MORE THAN 55 PSI FUEL PRESSURE, DAMAGE TO THE FUELING SYSTEM COMPONENTS CAN OCCUR.
