TM 9-2350-247-10 START ENGINE (M548A1) — Continued 0013 00 C A U T I O N If the engine doesn’t start after 30 seconds of cranking, release the START switch and let the starter cool for 30 seconds before you try again. If you can’t restart the warm engine in five tries, notify unit maintenance. 20. Push in the fuel cut-off and press the START switch to restart the engine. C A U T I O N Normal idle is 650–700 rpm, and normal coolant temperature is 160 F–230 F (71 C–110 C). If you let the engine run at idle for too long, the engine could cool below 140 F (60 C). Running below 140 F (60 C) for very long can damage the engine. Run the engine at 1,200–1,500 rpm to keep coolant temperature in the normal range. NOTE If the instruction plate on the door of your carrier says to warm up the transmission in 1–3 range, you have the wrong plate. Notify unit maintenance. 21. Put the transmission range selector in 2-3 range and set the hand throttle to run the engine at 800–1,000 rpm for about 10 minutes. This is to warm up the transmission. 0013 00-13
