Installation of the Solenoid Valve of the Elevator Servo-Control Actuator
WARNING:
MAKE SURE THAT THE GROUND SAFETY-LOCKS ARE IN POSITION ON THE LANDING GEAR. THIS WILL PREVENT UNWANTED MOVEMENT OF THE LANDING GEAR, AND THUS POSSIBLE INJURY TO PERSONS AND DAMAGE TO THE AIRCRAFT AND/OR EQUIPMENT.
WARNING:
MAKE SURE THAT THE TRAVEL RANGES OF THE FLIGHT CONTROLS SURFACES ARE CLEAR. MOVEMENT OF FLIGHT CONTROLS CAN CAUSE INJURY TO PERSONS AND/OR DAMAGE TO EQUIPMENT.
WARNING:
PUT THE SAFETY DEVICES AND THE WARNING NOTICES IN POSITION BEFORE YOU START A TASK ON OR NEAR:
- THE FLIGHT CONTROLS
- THE FLIGHT CONTROL SURFACES
- THE LANDING GEAR AND THE RELATED DOORS
- COMPONENTS THAT MOVE.
WARNING:
YOU MUST PUT ON AND ATTACH A SAFETY HARNESS BEFORE YOU START WORK:
- ON THE THS OR IN THE REAR FUSELAGE
- ON TOP OF THE WINGS OR PYLONS.
CAUTION:
DO NOT CAUSE DAMAGE TO THE SURFACES. THE COMPONENTS ARE MADE OF CARBONFIBER REINFORCED PLASTIC.
NOTE: Only the installation of one solenoid valve of elevator servo-control actuator 34CE1 is given. The installation of solenoid valves 1 and 2 of elevator servo-control actuators 34CE2, 34CE3 and 34CE4 is the same.
