737 GENERAL -- HYDRAULIC POWER OPERATION General
You pressurize the hydraulic systems with a ground service cart or with the hydraulic pumps.
The switches on the hydraulic panel lets you control hydraulic system A and B hydraulic pumps.
The flight control panel lets you control the standby hydraulic system.
Ground Service Cart Pressurization
To pressurize hydraulic system A, connect a ground service cart to the left ground service disconnect.
To pressurize hydraulic system B, connect a ground service cart to the right ground service disconnect.
You can not pressurize the standby system from a ground service cart.
Hydraulic Pump Pressurization
You use the hydraulic panel to operate and to monitor the hydraulic pumps for system A and B. The flight control panel lets you operate the standby pump.
You pressurize system A and B with an engine-driven pump (EDP) or an electric motor-driven pump (EMDP). The ELEC 1 and ELEC 2 switches on the hydraulic panel let you control the EMDPs. The hydraulic low pressure lights go off when the hydraulic pressure is normal.
737-600/700/800/900 TRAINING MANUAL
Normally, the engine-driven pumps are on. When the engines are on, the engine-driven pumps come on to also pressurize systems A and B.
An overheat light lets you monitor the system temperature.
Training Information Point
If you pressurize the hydraulic systems with the hydraulic pumps, make sure there is sufficient fuel in the main fuel tanks to remove heat from the heat exchangers.
To pressurize a hydraulic system with a ground service cart, first you must remove the pressure from the hydraulic reservoir.
WARNING:  KEEP PERSONS AND EQUIPMENT AWAY FROM ALL CONTROL SURFACES AND THE NOSE GEAR WHEN HYDRAULIC POWER IS SUPPLIED. THE AILERONS, ELEVATORS, RUDDER, FLAPS, SLATS, SPOILERS, AND THE NOSE GEAR ARE SUPPLIED WITH POWER BY THE HYDRAULIC SYSTEMS. INJURIES TO PERSONS OR DAMAGE TO EQUIPMENT CAN OCCUR WHEN HYDRAULIC POWER IS SUPPLIED.
CAUTION:  YOU MUST MONITOR THE INSTRUMENTS AND INDICATOR LIGHTS FOR THE HYDRAULIC SYSTEMS WHEN HYDRAULIC SYSTEMS ARE PRESSURIZED. THIS IS TO MAKE SURE THE HYDRAULIC SYSTEMS OPERATE CORRECTLY. IF THE OVERHEAT LIGHT OF A

HYDRAULIC SYSTEM COMES ON, YOU MUST STOP THE
OPERATION OF THAT HYDRAULIC SYSTEM
IMMEDIATELY. DAMAGE TO THE EQUIPMENT CAN OCCUR
IF YOU DO NOT DO THIS.

CAUTION:  DO NOT OPERATE THE EMDP FOR MORE THAN TWO MINUTES IF A MAIN FUEL TANK CONTAINS LESS THAN 250 GALLONS (1675 POUNDS/761 KILOGRAMS) OF FUEL. YOU MUST LET THE RESERVOIR TEMPERATURE DECREASE TO AMBIENT TEMPERATURE BEFORE YOU OPERATE THE PUMP AGAIN. DAMAGE TO EQUIPMENT CAN OCCUR IF YOU DO NOT DO THIS.
