Truck Fill range of 50 to 600 gpm (3 to 38 Valves lps). Verify TFV closes rapidly when outlet pressure exceeds control set point. Verify TFV opens when the deadman control lever is pressed. Verify TFV closes after the deadman control lever is released. If equipped, verify operation of solenoid connected to grounding verification system. Ground verification system should energize solenoid when an acceptable ground is detected by the ground verification unit. Systems that have overflow protection systems must be inspected and maintained concurrently with the inspection and maintenance of TFVs. Refer to for additional inspection SM SM SM As required and maintenance requirements. Motor Operators (Section 6-6.6) Visually inspect motor operators to SM SM SM ensure smooth movement during opening and closing operation and adjust, if necessary, to ensure that they are opening and closing fully. Quarterly Listen for and investigate unusual noises during operation. Operators Lubricate mechanical overrides (if equipped). Refer to for inspection and SM SM SM maintenance requirements of As required electric motors
