5. On Forward Control models, push choke knob in part
way as soon as engine starts and adjust throttle for smooth idle.
6. Note oil gauge and ammeter readings. Ammeter should
show some charge unless engine is idling slowly. Oil gauge
should show some pressure. In unusually cold weather the oil
gauge needle may go over nearly to 60. If so, run the engine
just above idling speed until the pressure drops to around
the midpoint of the gauge before driving vehicle. Refer to

for procedures when pushing vehicle to start engine.
On Forward Control models, the choke knob should be pushed
in all the way as soon as the engine is sufficiently warmed up.
Moving and Stopping
Engine should be warmed-up to operating temperature at
idle speed with lever in "N" position, particularly in cold
weather. With a cold engine the vehicle may tend to creep
when placed into a drive position while running at fast idle.
A slight application of brake will hold vehicle until motion is
desired. With the lever placed into any of the forward drive
positions, the vehicle will move forward when accelerator is
depressed. The shift events (1st to 2nd; 2nd to 3rd; etc.) will
occur at progressively higher speeds, depending upon accelera-
tor pressure. With slight accelerator pressure, the shifts occur
at lower speeds. As accelerator pedal is depressed, shifts
occur at higher speeds.
To stop the truck, release the accelerator pedal and apply
brakes. Do not move the lever from range selected. When
ready to move again, release brakes and depress accelerator
pedal as desired.
Reversing
While it is advisable to be at a complete stop before
engaging reverse, 'it is possible to shift into "R" (figs. 27 and
28) while vehicle is in slight (1 to 2
mph) forward motion. Avoid engag-
ing reverse at forward speeds above
1 to 2 mph. This permits moving the
lever between
"R"
and any forward
range with light accelerator pedal
pressure, permitting rocking the
vehicle when required to get out of
mud, snow, or sand. With Hydra-
Matic raise the lever when moving
