2. Turn the key on the Control Power switch to the left Glow Plug position and hold the key in place for five seconds,
or until the glow plug indicator turns red. As soon as it is glowing, turn the key to the right Start position and hold
it until the engine cranks and starts running. Release the key, it will move to the Run position.
Note: For cold weather conditions, refer to the engine operator’s manual for appropriate glow plug interval.
Do not crank the engine longer than 10 seconds at a time. If the engine will not start, wait
30 seconds to allow the starter motor to cool and then repeat the starting procedure.
Excessive cranking will cause damage to the starter.
Note: If oil pressure is not obtained within 15 seconds after the key is switched to the Run position, the low oil
automatic shutdown will turn off the fuel supply, stopping the engine. Check the oil level and turn the key to the OFF
position to reset the oil pressure timer before attempting to restart the engine.
3. Once the engine is running, allow it to reach normal operating temperature before switching on any loads.
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.
VOLTAGE REGULATION
Units are equipped with an electronic voltage regulator. The voltage regulator controls the output of the generator
by regulating the current into the exciter field. The regulator has three screwdriver adjustable potentiometers that
may be adjusted for voltage, stability and voltage roll-off (U/F). 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).
WET STACKING
The unit is powered by a diesel engine. Diesel engines are susceptible to wet stacking if lightly loaded. Wet stacking
occurs when an engine is run at less than 30% of its full load capacity, causing unburned fuel to accumulate in the
exhaust system. Wet stacking can be detected by continuous black exhaust when the unit is under a constant load.
It can also cause fouling of injectors and buildup on engine valves. Diesel engines operate properly when applied
loads are between 30% and 100% capacity. Appropriate generator sizing is determined by the anticipated load. If
the unit is in a wet stack condition, load the unit heavily for five hours or until the exhaust is clear
