START ENGINE - CONTINUED

NOTE

If engine is not cranking, attempt to start engine by using emergency start switch and capacitor power: Turn

ignition switch to ON, hold emergency start switch in up (ON) position, then start engine.

Turn and hold ignition switch all the way clockwise and crank engine until it starts or 30 seconds has elapsed. When

engine starts, release ignition switch.

High water temperature/low oil pressure (HIGH WATER LOW OIL) light and alarm, CHK ENG. light, and CHECK

TRANS light should go off.

ENG PREHEAT light will turn back on if engine ECM determines further air intake heating is required.

STOP ENG. light will come on momentarily, then turn off.

If engine does not start, turn ignition off and allow starter motor to cool for two minutes.

Repeat steps 4 and 5.

NOTE

After engine has started, air inlet manifold heater may continue to operate in a continuous and/or intermittent

mode. Air inlet heater will turn off when sum of coolant and air inlet temperatures exceeds 127F (53C).

Due to electrical design of yard tractor, engine may be running without alternator charging the batteries. If volt-

meter indicates batteries are not charging, shut down engine and slave start tractor (WP 0006 00).

Allow engine to run at low idle (700-750 rpm) to warm engine up to normal operating temperature. In cold weather oper-

ating mode, engine ECM will automatically increase engine speed to 1000 rpm to facilitate warm-up.

When pressure in air reservoirs has reached 65 psi (448 kPa), LOW AIR light and warning buzzer will turn off. It is now

safe to operate tractor.

OPERATE TRANSMISSION

NOTE

Refer to WP 0004 00 for a complete description of the transmission range selector.

Transmission Ranges.

R (Reverse) is used to back up the vehicle. Vehicle must be brought to a complete stop before shifting from a forward

range to R or vice versa. Backup alarm will sound when vehicle is in reverse.

N (Neutral) is the normal transmission position when vehicle is not in use. Use N to start engine, when idling engine,

and for parking.

When placed in D (Drive), the transmission starts out in 1st gear and automatically progresses to the highest (5th)

gear. During slowdown, the transmission automatically downshifts.

To select a specific forward gear, move transmission range selector lever to 4, 3, 2 or 1 position. The greater the need

for engine power or engine braking power, the lower the gear selection should be.

(1) Use 4th, 3rd or 2nd gears when road, load or grade conditions make it preferable to use lower gears.

(2) Use 1st gear to pull through mud, snow or when going up steep grades or up ramps in RO/RO operations. This

gear selection also offers maximum engine braking power for downhill grades or ramps.

(3) When conditions improve, return vehicle to D (Drive).
