12.1.2.3
Stop the launch vehicle for cooling off periods. Idle engine as often as possible.
12.1.2.4
Check the oil levels often. Oil seals are more likely to leak in extreme hot weather.
12.1.2.5
If the temperature of the transmission fluid is above 270 degrees F (132 degrees C)
the CHECK TRANS light will illuminate.
12.1.2.6
If the TRANS TEMP gauge (Figure 12. 2. (2)) reads higher than 250 degrees F (121
degrees C), do the following:
e. Stop launch in safe position and turn 4 position rotary switch to position 1 whist
engine is running to reduce idle speed.
f.
When the TRANS TEMP gauge (Figure 12. 2. (2)) reads in normal range, return
rotary switch to its previous position and continue build.
g. If the TRANS TEMP gauge (Figure 12. 2. (2)) does not return to normal range,
stop engine and let transmission cool.
h. When the TRANS TEMP gauge (Figure 12. 2. (2)) reads in normal range, start
engine, return rotary switch to its previous position and continue build.
12.1.2.7
If temperature of the hydraulic fluid is above 212 degrees F (100 degrees C), the
HIGH TEMPERATURE oil light will illuminate on the interface panel and the chest
pack fault light will flash. If the HIGH TEMPERATURE warning comes on, do the
following:
a. Stop launch in safe condition and turn 4 position rotary switch to position 1 to
reduce idle speed.
b. When the HIGH TEMPERATURE warning light goes off, return rotary switch to
its previous position and continue build.
c.
If the HIGH TEMPERATURE warning light does not go off, stop truck and let the
hydraulic oil cool.
d. When the HIGH TEMPERATURE warning light goes off, return rotary switch to
its previous position and continue the build.
