Figure 3-10. Master switch, master warning light, hand throttle, and starter buttons.
(b) Press the starter button (fig. 3-10) for not more than 30 seconds. When the engine starts, release the starer button and
t
set the throttle to obtain 600 r.p.m. engine warmup speed. For engine warmup, proceed as follows:
1.
Operating temperatures. Run engines at 600 r.p.m.'s until normal operating temperature is established. Operating
temperature ranges of engine coolant (1600F. - 1850F.) (710C. - 85 .), engine lube oil (1600F. - 2350F.) (710C. - 1130C.),
C
transmission oil (1400F. - 2000F.) (60 . - 93 .), marine gear oil (1400F. - 2000F.) (600C. - 930C.), and gathering oil (1400F. -
C
C
2000F.) (600C. - 930C.) should be attained as the engines warm up. If the temperature increases rapidly during the warmup period
or during operation, the LARC should be stopped and condition reported to organizational maintenance.
2. Oil pressure. After the engine warms up, oil gages should read as follows: engine (30.50 p.s.i. at 1200 r.p.m.),
transmission (140-160 p.s.i.), gathering box (5-10 p.s.i.), and marine gear (180-210 p.s.i.)
3. Battery-generator indicator. The battery-generator indicator (fig. 3-11) may indicate a high charging rate for the first few
minutes after the engines have started. Normal indicator reading is in the green zone.
