AUTOMATIC SHUTDOWN
This unit is equipped with a low oil pressure and high coolant temperature automatic shutdown system. This system
will automatically shut off the fuel supply to stop the engine if oil pressure drops too low or the engine exceeds normal
operating temperature. Return the switch to the “OFF” position to reset the unit after you have determined the cause
of the shutdown.
LIGHT OPERATION
WARNING
NEVER OPERATE THE LIGHTS WITHOUT THE PROTECTIVE LENS COVER, OR WITH
A LENS COVER THAT IS CRACKED OR DAMAGED. The bulbs in the light fixtures
produce high temperatures and operate under pressure. A broken or missing lens
cover could cause the bulbs to shatter, causing injury.
1. Once the engine is up to temperature and running
smoothly, switch the main circuit breaker (A) to the
“ON/I” position.
2. With the main circuit breaker on, switch each individ-
ual circuit breaker for the lights (B) to “ON/I”, one at
a time.
3. The ballast indicator lights (C) will come on and
continue to get brighter as the lights warm up, and
then remain on. This confirms that power is coming
from the ballasts to the lights.
4. If an indicator light does not come on, the ballast may
need to be serviced. If the indicator light comes on
and stays lit, but the related light is not illuminated,
check the bulb or the mast wiring. Refer to “Trouble-
shooting the Lights” on page 29.
5. The lights require a warm up period of 5-15 minutes before they reach full output. If the lights are shut down,
they require a cool down period of approximately 10 minutes before they can be switched on again.
6. The light tower uses four 1000W bulbs. When checking or replacing the bulbs, wipe them with a clean cloth to
avoid leaving any grease, oil residue or fingerprints on the glass. Any residue can create a hot spot on the bulb,
causing premature bulb failure.
CAUTION
Bulbs become extremely hot when in use. Allow bulb fixture to cool 10-15 minutes before
handling or lowering the mast.
VOLTAGE REGULATION OPTION
Some units may be equipped with an electronic voltage regulator. The voltage regulator controls the output of the
generator by regulating the current into the exciter field. The voltage regulator is adjusted before shipment from the
factory. Contact Magnum Power Products LLC for additional information before attempting to adjust the voltage
regulator.
DERATING FOR ALTITUDE
All units are subject to derating for altitude and temperature; this will reduce the available power for operating tools
and accessories connected to the receptacles. Typical reductions in performance are 2-4% for every 1000 ft (305
m) of elevation and 1% per 10ºF (5.6ºC) increase in ambient air temperature over 72ºF (22ºC).
