How long can the Ground Maintenance Motor Pump operate to charge low actuator pressures when the BATT/TOW switch is set to tow?

The Ground Maintenance Motor Pump is designed to operate only for short, intermittent durations when the BATT/TOW switch is set to tow. This limitation ensures that the system does not overheat or become damaged. Operating for 2-3 seconds intermittently allows the pump to charge low actuator pressures adequately while preventing potential overheating or wear from continuous operation. This functionality is essential for maintaining system integrity and performance during ground maintenance activities. Operating continuously, even for a minute, could lead to system failure or reduced lifespan of components, which underscores the importance of short, controlled bursts of operation for proper functionality.
