ENGINE OPERATION

STARTING THE ENGINE
1. Open the engine compartment door and check that
the fuel shutoff valve located to the left of the fuel
filter housing is in the open position (lever to be in
line with the hose).
2. Make sure battery disconnect switch is in the on
position.
3. Check for proper oil level and coolant level. Close
engine compartment door.
4. Remove all plugs connected to the AC power
receptacles.
5. Set IDLER switch to "AUTO".
6. Firmly set the Operator Selector Switch to Single or
Dual. The Operator Selector Switch can be set to
Single or Dual mode and must be securely in one of
the two positions.
7. Set the RUN/STOP switch to "RUN". Observe that
the engine protection and battery charging lights
are on.
7a. Press Glow Plug Button and hold 15 to 20 seconds.
8. Press START button until the engine starts or for up to 10
seconds.
9. Release the engine START button when the engine
starts.
10. Check that the engine protection and battery
charging lights are off. If the engine protection light
is on after starting, the engine will shutdown in a
few seconds. Investigate any indicated problem.
11. Allow the engine to warm up at low idle speed for
several minutes before applying a load and/or
switching to high idle. Allow a longer warm up time
in cold weather.
COLD WEATHER STARTING
With a fully charged battery and the proper weight oil,
the engine should start satisfactorily even down to
about 0°F(-18°C). If the engine must be frequently
started below 10°(-12°C), it may be desirable to install
the optional ether start kit (K887-1). For extreme cold
conditions it may be desirable to install additional
equipment such as a block heater or oil pan pad
heater, etcetera.
NOTE: Extreme cold weather starting may require
longer glow plug operations.
STOPPING THE ENGINE
1. Switch the RUN/STOP switch to "STOP". This turns
off the voltage supplied to the shutdown solenoid. A
backup shutdown can be accomplished by shutting
off the fuel valve located on the fuel line.
