R R (b) Monitor the increase of the fluid level on the quantity indicator.
R R R R (c) Make sure that the filling pressure is not more than 30 bar (435.1131 psi) and the flow rate is not more than 12 l.min (3.1700 USgal.mn).
R R (d) Stop the flow of hydraulic fluid when the pointer of the quantity indicator is at the center of the colored line at the applicable system.
NOTE : The hydraulic fluid volume in the reservoirs can change____ with the temperature. For every 10 DEG.C scale Celcius (which is every 18 DEG.F on the scale Fahrenheit) change in outside air temperature:
- the volume in the reservoir of the Green hydraulic system can change by 0.85 l (0.2245 USgal)
- the volume in the reservoir of the Yellow hydraulic system can change by 0.64 l (0.1690 USgal)
- the volume in the reservoir of the Blue hydraulic system can change by 0.51 l (0.1347 USgal).
NOTE : If the temperature is above 20 DEG.C (68.00 DEG.F) the____ quantity indicator pointer must be in the top half of the applicable scale range.

R (5) If the reservoir is filled too much, drain the unwanted hydraulic fluid:
-
for the reservoir of the Green hydraulic system (Ref. TASK 29-10-00-680-001)
-
for the reservoir of the Yellow hydraulic system (Ref. TASK 29-10-00-680-002)
-
for the reservoir of the Blue hydraulic system (Ref. TASK 29-10-00-680-003).
R (6) Turn the selector 1134GQ to the NEUTRAL position.
R (7) Make sure that the colored light on the quantity indicator 1834GQ
goes off.
R (8) Disconnect the hydraulic service cart from the reservoir fill connection 1007GM and install the blanking cap.
R (9) If you have filled the hydraulic system after:
-maintenance or,
-removal/installation of large hydraulic components or,
-hydraulic fluid low level (loss of the hydraulic system) or,
-high loss of hydraulic fluid, you must do the related bleed procedure to make sure that the quantity of hydraulic fluid in the system is correct:
-
for the reservoir of the Green hydraulic system (Ref. TASK 29-00-00-870-003)
-
for the reservoir of the Yellow hydraulic system (Ref. TASK 29-00-00-870-007)
-
for the reservoir of the Blue hydraulic system (Ref. TASK 29-00-00-870-008) and (Ref. TASK 29-00-00-870-009).
