WARNING:
OBEY THE HYDRAULIC SAFETY PROCEDURES.
WARNING:
DO NOT WALK ON A CLOSED LANDING GEAR DOOR.
CAUTION:
USE HIGH-PRESSURE SPRAYING EQUIPMENT FOR SPECIFIED AREAS ONLY.
DO NOT USE HIGH-PRESSURE SPRAYING EQUIPMENT TO CLEAN THE AREAS AROUND SENSORS, PROBES, ANTENNAS, ETC.
YOU MUST CLEAN THESE AREAS BY HAND.
MAKE SURE THAT YOU ADJUST THE HIGH-PRESSURE SPRAYING EQUIPMENT TO, AND USE IT AT, THE SPECIFIED VALUES.
IF YOU DO NOT OBEY THESE PRECAUTIONS, YOU CAN CAUSE DAMAGE TO THE SURFACE OR TO PARTS. HIGH-PRESSURE SPRAYING EQUIPMENT CAN PUSH LIQUIDS INTO BEARINGS, JOINTS, PROBES, BRAKES, ELECTRICAL CONNECTORS AND OTHER SEALED COMPONENTS.
LIQUIDS THAT GO INTO THESE AREAS CAN FREEZE DURING AIRCRAFT FLIGHT, REMOVE LUBRICANTS, CAUSE CORROSION AND ELECTRICAL FAULTS.
