Engine Controls And Instruments

1.Oil pressure gauge
shows the pressure of the lubricating oil in the engine. As soon as the engine is started, the oil pressure gauge should start to register. The minimum oil pressure at normal temperature and maximum operating speed should be 30 psi (207 kPa).
2.Voltmeter
shows the voltage in the electrical system. The normal range is 12 to 14 volts with the engine running, 12 volts with the engine not running (batteries only).
3.Water temperature gauge
shows the engine coolant temperature. Normal temperature is 175 to 200°F (80 to 93°C).
4.Heat/start switch
the switch has four positions:
a.Off
shuts the engine down.
b.Run
activates only the engine electrical circuits.
c.Heat
activates the engine heating system (thermostart).
d.Heat & start
activates the thermostart and the starter.
5.Throttle
sets the engine speed.

6.Clutch control lever
the clutch control lever is connected to the end of the clutch release shaft and is used to engage or disengage the conveyor power train from the engine. Moving the lever toward the engine engages the clutch and connects the power train to the engine.


NOTICE

SET THE ENGINE SPEED AS SLOW AS POSSIBLE WHEN ENGAGING THE CLUTCH.


7.Battery switch
isolates the batteries from the machine circuits when at "Off" or connects the batteries to the circuits when at "On".

Starting The Engine Under Normal Conditions

1. Set the battery switch at "On".
2. Push in the button on the throttle control and pull the control slightly out.
3. Turn the heat/start switch all the way clockwise and hold it while adjusting the throttle control.
4. As soon as the engine starts, release the heat/start switch.

Be sure the starter and flywheel have both stopped turning before re-engaging the starter.


NOTICE

DO NOT INCREASE OR DECREASE THE ENGINE SPEED RAPIDLY IMMEDIATELY AFTER THE ENGINE STARTS OR THE TURBOCHARGER COULD BE DAMAGED.


Cold Weather Starting Of The Engine

1. Set the battery switch at "On".

2. Turn the heat/start switch clockwise to the heat (number 3) position and hold it there for 15 to 20 seconds.
3. Pull the throttle control all the way out.
4. Turn the heat/start switch as far clockwise as possible, thereby engaging the starter. If the engine does not start within 15 seconds, return the switch to the heat (number 3) position for 10 seconds and then move the switch clockwise as far as possible again.
5. As soon as the engine starts, release the heat/start switch.


NOTICE

DO NOT INCREASE OR DECREASE THE ENGINE SPEED RAPIDLY IMMEDIATELY AFTER THE ENGINE STARTS OR THE TURBOCHARGER COULD BE DAMAGED.


Running The Engine

Run the engine at part throttle and no load until the water temperature gauge shows at least 140°F (60°C).


NOTICE

SET THE ENGINE SPEED AS SLOW AS POSSIBLE WHEN ENGAGING THE CLUTCH.


During long engine idling periods, the engine coolant temperature will fall below the normal operating range. The incomplete combustion of fuel in a cold engine will cause crankcase dilution, formation of lacquer or gummy deposits on the valves, pistons and rings and rapid accummulation of sludge in the engine. Do not idle the engine for extended times unless absolutely necessary.

Stopping The Engine


NOTICE

STOPPING THE ENGINE IMMEDIATELY AFTER IT HAS BEEN UNDER LOAD CAN RESULT IN OVERHEATING AND ACCELERATED WEAR OF THE ENGINE COMPONENTS. FOLLOW THE STOPPING PROCEDURE OUTLINED BELOW, TO ALLOW THE ENGINE TO COOL.


1. Disengage the clutch, push the throttle control all the way in and let the engine run with no load for five minutes.
2. Stop the engine by moving the heat/start switch all the way counterclockwise.
3. Set the battery switch at "Off".


NOTICE

ALWAYS SHUT THE ENGINE DOWN AS DESCRIBED ABOVE AND REMOVE THE KEY BEFORE LEAVING THE MACHINE.
