 WARNING: PRESSURIZATION OF A MAIN HYDRAULIC SYSTEM WILL SUPPLY POWER TO
_______ COMPONENTS OF THE AILERON, ELEVATOR, RUDDER, SPOILER, WING FLAPS, LANDING GEAR SYSTEMS AND WHEEL WELL DOORS. WHEN YOU SUPPLY THE HYDRAULIC POWER, THE AILERONS AND ELEVATORS WILL TRY TO MOVE TO THE NEUTRAL POSITION. ALSO, ALL SYSTEMS WILL TRY TO MOVE TO THE POSITION OF THE CONTROLS. MAKE SURE YOU ISOLATE THE SYSTEMS AND CONTROLS WHICH MUST NOT OPERATE TO PREVENT MOVEMENT OF COMPONENTS WHICH CAN CAUSE INJURY TO PERSONS OR DAMAGE TO EQUIPMENT.
