Section I. OPERATING IN EXTREME CONDITIONS
CAUTION
Equipment damage. When operating launch vehicle in very hot temperatures of above 100
degrees F (38 degrees C), extra care must be taken to prevent overheating engine
(temperatures over 230 degrees F (110 degrees C)) and transmission (temperatures over
250 degrees F (121 degrees C)). Watch water and transmission temperature gauges
closely.
Equipment damage. Check oil levels often and keep operating temperatures as low as
possible. Truck cooling and lubrication systems support each other. Failure of one
system may rapidly cause failure of other system.
Equipment damage.
Check interface panel for any warning lights when in launch
conditions.
12.1.1.1
Keep operating temperature as low as possible.
12.1.1.2
Put the transmission range selector (Figure 12. 1.1) in Neutral (N) position while
engine is running. Let the engine idle for about two minutes before shutting down.
Idling will cool the engine faster than quick shutdown and may prevent damage from
remaining engine heat.
Figure 12. 1 Transmission Selector
12.1.1.3
Stop the launch vehicle for cooling off periods. Idle engine as often as possible.
