Operating Instructions
Voltmeter
The voltmeter displays battery and charging system voltage. An indication of low or high voltage (the red area) indicates an electrical system failure. The cause of the failure should be determined and cor- rected.
Water Temperature Gauge
The water temperature gauge monitors engine cooling system temperature. If engine coolant temperature exceeds 230° F (110° C), an overheat condition exists; the water temperature light will come on and the warning horn will sound.
WARNING
If engine cooling system overheating is indicated, continued operation of the en- gine, even for a short time, COULD result in fire, risk of personal injury, and severe damage to equipment.
Oil Pressure Warning Light
The oil pressure warning light indicates that engine oil pressure is below the safe operating level [below 7 PSI (48 kPa)]. This light (and warning horn) will come on when the ignition is turned ON, but should go off after the engine is started. If the light fails to come on when the ignition switch is turned ON, it could indicate a burned out bulb. If the light comes on during engine operation, stop the engine immediately and correct the source of the problem before further engine operation.
IMPORTANT: Continued operation of the engine with an illuminated oil pressure warning light MAY cause severe engine damage (if a low oil pressure condition exists).
Water Temperature Warning Light
The water temperature warning light indicates that engine coolant temperature is above the safe operating limit and the engine is overheating. If this light comes on, there may be a problem with:
•Radiator cooling air flow (material packed into radiator cooling fins, clogged air intake screen)
•Low coolant quantity in cooling system
•Engine fan belt
•Thermostat function
Stop the engine and correct the problem before further operation.
IMPORTANT: Continued operation of the engine with an illuminated water temperature warning light MAY result in severe engine damage.
Ignition Switch
The ignition switch is used to start and stop the engine (and preheat the diesel engine). The switch
has four positions: 
is the glow plug preheat po- sition; “O” is theOFF position; RUN is the position the key returns to after starting; “S” is theSTART po- sition. When starting the engine, turn the key clockwise to the “S” position. Do not hold the key in the “S” position longer than 10 seconds. If the engine does not start, return the key to the “O” position for at least 60 seconds before making a restart attempt. Prolonged cranking can damage the starter motor and shorten battery life. Release the key when the engine starts, and it will return to the RUN position. To stop the engine, rotate the key counterclockwise to the “O” position.
NOTE: When starting the engine, turn and hold the ignition key in the glow plug preheat position. The time required is approximately 10 to 30 seconds, depending on engine temperature. Refer to STARTING THE ENGINE in this section.
