TM 5-4320-302-14Table 2-1. Operator's Controls and Indicators-ContinuedControl orKeyIndicatorFunction4ENGINE PRIMEPush-pull cable. T-handle mechanically connected to fuel feed pumpT-handlepriming lever. Used to prime engine by forcing fuel from fuel tankinto fuel system.5PUSH TO STARTStarts engine. Starter pushbutton when pushed allows electric currentpushbuttonto flow to the starting solenoid. The starting solenoid then allowscurrent to flow to the starter motor.6ON-ENGINE-OFFTurns engine on and off. Energizes electrical system for engineswitchoperation.7Fault sensitiveShuts down engine if any of the following occur: (1) Low oilcontrolpressure-below 20 pounds per square inch (psi) (137.9 kilopascals[kPa] ); (2) high engine cylinder head temperature; or (3) engineoverspeed-greater than 3050 rpm. Has red pushbutton reset thatalso has to be pushed when starting engine.8Charging indicatorCharging indicator light comes on when ON-ENGINE-OFF switchlightis ON before starting engine. Once engine is running, charging in-dicator light will go out. Charging indicator light will come on againif alternator is not charging the battery and when engine is shutdown. The charging indicator light will go out again a few secondsafter engine shutdown.9AmmeterIndicates battery charge or discharge in amperes (A). Electricallyconnected in series to battery circuit. Graduated in 5 A incrementsfrom 0 to +60 A and 0 to -60 A.10Oil pressure gageSwitchgage indicates engine oil pressure in psi and kilopascals (kPa).Mechanically connected by the oil pressure line hose assembly tothe engine oil lubrication system on the outlet side of the lube oilpump. Graduated in 10 psi (68.9 kPa) increments from 0 to 100 psi(0 to 689.5 kPa). Has mechanical lever to set low oil pressuresetpoint associated with the fault sensitive control to shut downengine.2-2
