3.16.1 Check the engine oil, fuel and coolant levels.
Note: If the fuel tank was drained or run dry it may be necessary to
bleed the fuel lines.
3.16.2 Check the condition of the electrical cable on the mast. Do not start the
generator if the insulation on cable is cut or worn through.
3.16.3 Check that the circuit breakers (a, b, c) are in their OFF position.
CAUTION: Starting the engine under load will damage the machine.
3.16.4 On machines equipped with the Caterpillar engine, turn the key (r) one
click left to the HEAT position and hold until the glow plug indicator
turns red. (This will take approximately 30 seconds.)
3.16.5 Turn the key (r) to START and hold until the engine starts. Release the
key after the engine starts.
CAUTION: Do not crank engine longer than 10 seconds. This could
cause starter motor to overheat. Return switch to OFF and wait 15-30
seconds for starter motor to cool down before attempting to preheat
and restart.
Note: If oil pressure is not obtained within 30 seconds after key is
turned to RUN, the automatic shutdown system will shut off the fuel
supply. You must return the key to the OFF position to restart the 30
second timer before attempting to restart the engine.
3.16.6 Allow engine to warm up before operating floodlights.
3.17 Automatic Shutdown
This unit is equipped with a low oil, high temperature auto-shutdown
system. This system will automatically shut off the fuel supply to the
engine if the oil pressure drops too low or the engine exceeds normal
operating temperatures. Return the key switch to “OFF” to reset the
unit after an engine shutdown.
