Functional Description
TM 1-1730-231-13&P activated.  A  thermal  circuit  breaker  is  installed  in  the  motor  case  to  safeguard  the  control  circuit.  An  electromagnetic interference filter is also installed in the motor case. A grounding cable with one end to fit the aircraft receptacle is also stored on the shelf. Table 1-1. Equipment Data CHARACTERISTICS PARTICULARS Width 32 inches (in) (812.8 millimeters (mm)) (overall) Depth 24 in (609.6 mm) Height 45 in (1143.0 mm) (including handle) Weight 225 pounds (102.04 kilograms) (dry, excluding hoses) Housing Metal, weather resistant Mobility Two semi-pneumatic tires for moving the cart. Tiedown holes provided in legs at front corners. Ambient Temperature -25 Deg. F (-32 Deg. C) to 125 Deg. F (52 Deg. C) Storage Temperature -65 Deg. F (-54 Deg. C) to 160 Deg. F (71 Deg. C) Fluid Temperature 200 Deg. F (93 Deg. C) (maximum) Output Capability 1.2 gpm at 1,000 psi (minimum) 0.4 gpm at 3,000 psi (minimum) Reservoir Capacity 5 gallons (18.925 liters) Hydraulic Fluid MIL-H-5606 or MIL-H-83282 Voltage +24 vdc supplied by aircraft auxiliary power unit or batteries. SECTION III. TECHNICAL PRINCIPLES OF OPERATION 1-10. Functional Description. Activating the pump toggle switch S4 (Figure 1-4) to ON position energizes the start relay K1 and closes its contacts allowing the 24 vdc supply to energize the pump motor B1 (3, Figure 1-3).  The motor drives the gear pump (2) which takes hydraulic fluid from oil reservoir tank (14) and pumps to the filter (4). The 1 micron filtered fluid flows through the check valves (5) to the three solenoid valves (7) (L1, L3, and L5). Under normal conditions the solenoid valves (7) are closed while solenoid valve (11) should be in open position. This allows the fluid to recirculate through  solenoid  valve  (11)  back  to  the  oil  reservoir  tank  (14)  to  prevent  overheating  of  fluid.    To  remove  air  from hydraulic hoses, connect one end of hose to the cart disconnect (9) and the other to the bleed adapter. Insert the bleed adapter into the filler/breather and observe the fluid flow after activating and holding the respective switch (S1, S2, or S3) in RAISE direction for duration of flow. Fluid flow should be continuous and without air bubbles. When that is 1-8
