Stopping the engine
To stop the engine:
1. Shut down power to lights and external devices
plugged into the power receptacle.
2. Turn the engine key to the OFF position.
Automatic engine shutdown
The power system is equipped with an automatic
shutdown feature. This system prevents damage by
shutting down the engine when oil pressure is too low
or engine temperature is too high.
To restart the engine after an automatic shutdown has
occurred, return the engine key to the OFF position,
then follow the procedures above for starting the
engine.
Lights
Turning the lights on
To turn on the lights, first toggle the main circuit
breaker to ON (see Figure 3.8), then toggle the
individual circuit breakers for each light one at a time.
• Metal halide lamps require a warm-up time of 5 to
15 minutes before reaching full brightness.
• After the lamps are turned off, they will not turn
on again until they are cool. The lamps can take up
to 15 minutes to cool.

Turning the lights off
For increased lamp life, turn off lights and let the
lamps cool 15 minutes before lowering the tower and
moving the trailer.
After the lamps are turned off, they will not turn on
again until they are cool. The lamps can take up to 15
minutes to cool.
Degraded lamps
Degraded lamps may be difficult to light, and may
shut off unpredictably after starting.
Degraded lamps should be replaced.
Lamps that will not turn on
If the lamps do not light when power is applied,
ensure the appropriate circuit breakers are set in the
ON position. If the circuit breakers are on, and the
lights are not visibly lighted within 5 minutes, follow
these steps:
1. Switch all circuit breakers OFF. If any of the lights
were lit, allow the lights to cool for 15 minutes
before proceeding.
2. Lower the mast.
3. Ensure the lamps are cool.
4. Check that all lamps are tightened securely into
their sockets.
5. Check for, and replace, burned out lamps.
Lamp replacement
