Leave throttle lever at idle position. Engage STARTER (5) and FLAME
HEATER switch (6) at same time. Crank engine while applying heat for about
30 seconds. At this time, release heater switch and depress foot throttle
about halfway. If engine starts, release STARTER switch (5).
If engine does not start, continue cranking with throttle in idle position. Cycle
FLAME HEATER switch (6) 10 seconds ON and 3 to 4 seconds OFF until
engine starts. If engine does not start after 30 seconds, or an indication of
starting ceases for longer than 10 seconds, stop the starting procedure and
notify Organizational Maintenance.
With brakes still locked, set throttle to run engine at 1200 rpm and shift trans-
mission to 4th gear position. Continue to cycle FLAME HEATER switch (6)
until engine coolant temperature gage indicates 120° F to 140o F. Then shift
into neutral and idle engine. (If transmission temperature approaches 300° F
during warm-up, immediately shift to neutral until temperature approaches
normal range).
During warm-up, refer to instrument panel checkout procedure (p 2-88).
Shift transmission to 1 st gear position and drive vehicle slowly 100 yards, be-
ing careful not to stall engine. This warms lubricants sufficiently for normal
operation.
