2-12. STARTING THE ENGINE (Cont'd)
CAUTION
If ambient temperature is above 0F (-18C), do not operate starter
continuously for more than 20 seconds; wait 10 to 15 seconds
between periods of starter operation. Failure to do this may result
in damage to the starter.
If any instrument reading is not normal, stop engine. Failure to do
this may result in damage to the engine. Refer to troubleshooting,
If engine does not start, leave rotary switch in RUN position and
wait 10 to 15 seconds before trying to restart. Failure to do this
may result in damage to glow plugs or starter.
If you accidentally turn the rotary switch to ENG STOP position after
an unsuccessful attempt to start, wait 90 seconds before trying to
restart. Failure to do this may result in damage to glow plugs.
g. Place rotary switch (1) to START. Release lever after engine starts. Lever will
return automatically to RUN. Transmission indicator lamp (5.1) goes out when
engine starts.
NOTE
Before the engine reaches operating temperature, the wait-to-start
lamp may flicker and a clicking noise may be heard. This is due to
glow plug relay cycling and is a normal condition.
If the transmission lamp stays illuminated, notify maintenance.
Transmission damage can result if cause of light illumination is not
determined.
h. Allow engine to warm up for approximately one minute and ensure
instruments indicate the following:
(1) Oil pressure gauge (3) should register above approximately 6 psi (41 kPa)
with engine at idle.
(3) Fuel gauge (6) should indicate fuel level in fuel tank.
(4) Air restriction gauge (2) should not register within the red zone.
i. Stop engine if any of the following conditions occur:
(1) Excessive engine vibration.
(2) Oil pressure does not register or suddenly drops to or less than
approximately 6 psi (41 kPa) with engine at idle.
(3) Air restriction gauge (2) is within the red zone.
j. If engine overheating occurs:
(1) Park vehicle, allow engine to idle.
(2) Observe coolant temperature gauge (4) for steady cooling.
