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.
(8)
Use the bleed ports on the truck tilt positioners of the main landing gear, to remove the pressure from the positioners.
F.
Do the Test for the Air/Ground Relays (Fig. 501)
S 765-010
(1) Use a volt/ohmmeter to measure the voltage between pins 6 (+ voltage) and 12 (ground). The connectors to be measured are in column A of Tables 1 and 2. The measured voltage of each connector must be the same as the voltage shown in column B of Tables 1 and 2.
NOTE: When you measure a 0 VDC, a 500 ohm load resistor or the
____ equivalent must be connected in parallel with the volt/ohmmeter.
All the voltages are |2.0 volts.
