 WARNING:_______ BE CAREFUL WHEN YOU BLEED THE HYDRAULIC FLUID.  THERE IS
 PRESSURE ON THE HYDRAULIC FLUID.  WHEN YOU BLEED THE
 PRESSURIZED HYDRAULIC FLUID, IT CAN CAUSE INJURY TO PERSONS.

 CAUTION: PUT A FUNNEL ON THE BLEED PORT ON THE TRUCK TILT POSITIONER OF
_______ THE MAIN LANDING GEAR. THE HYDRAULIC FLUID WILL FLOW APPROXIMATELY THREE FEET FROM THE BLEED PORT. THE HYDRAULIC FLUID CAN CAUSE DAMAGE TO THE EQUIPMENT.
 (43)
 Use the bleed ports on the truck tilt positioners of the main landing gear, to remove the pressure from the positioners.
