STARTING THE GENERATOR

Read the vehicle manufacturer's instructions.
operator should become familiar with the vehicle in which this
generator is installed. Differences exist between vehicles. For
example, some vehicles may use a transfer switch to isolate
dockside power from the generator, while other vehicles may
use an isolating receptacle. Some vehicles may be equipped
with a DC converter, which allows the generator to power cer-
tain DC lighting and other DC loads.
To start the generator from either the generator control panel or
from the optional remote panel, proceed as follows:
1.
Turn OFF electrical loads using the means provided in the
vehicle (such as, a main-line circuit breaker or transfer
switch).
If starting from the generator control panel, turn OFF loads by
setting the generator's main-line breaker to the OFF (or open)
position. If starting from a remote panel, turn OFF loads using
the means provided in the vehicle (such as, a main circuit
breaker). Electrical load circuits will be turned ON, after the
generator has started, stabilized, and warmed up.
2.
If the engine is cold, press the Preheat switch for a maximum
of 15 to 30 seconds.
3.
While pressing the Preheat switch to crank the engine, hold
the engine Start/Stop switch in the START position. When the
engine starts, release the switches.
If the engine does not start after it has been
cranking for 15 seconds, release the Start/
Stop switch, wait 15 seconds, and try again.
Holding the switch for longer than 15 sec-
onds can damage the starter motor.
4.
Let the engine run at no-load for a few minutes to stabilize and
warm up.
5.
Turn ON electrical loads, using the means provided in the
vehicle (such as, a main-line circuit breaker or transfer
switch).

STOPPING THE GENERATOR

1.
Turn OFF all electrical loads, using the means provided in
the vehicle (such as, a main-line circuit breaker or transfer
switch).
2.
Let the generator run at no-load for a few minutes, to stabilize
internal engine generator temperatures.
Do not stop the engine/generator immedi-
ately after running under load. This can
overheat and damage the engine and/or gen-
erator.
3.
Press and hold the Start/Stop switch in the STOP position,
until the engine shuts off.

APPLYING LOADS TO
GENERATOR
When applying electrical loads to the generator, observe these
guidelines:
• Before applying electrical loads, let the generator stabilize and
warm up for a minute or two.
• DO NOT overload the generator.
2.6.1
LETTING THE ENGINE STABILIZE
The generator supplies correctly rated voltage only at the proper
governed speed. Some electrical appliances may be extremely
sensitive to voltage. Incorrect voltages can damage such appli-
ances.
Electrical loads applied on the engine at reduced operating speeds,
such loads imposed on the engine, when sufficient power is not
available, may shorten engine life. Never turn ON electrical loads
until after the generator engine has started and stabilized at no-
load.
2.6.2
DO NOT OVERLOAD THE GENERATOR
Read the rated wattage/amperage capacity of the generator on the
generator data label located below the user control panel.
Applying electrical loads in excess of the unit's rated capacity may
trip the line breaker or cause the engine/generator to shut down.
To avoid overloading, add up the wattage of all connected electrical
lighting, appliance, tool, and motor loads. This total should not be
greater than the generator's rated wattage capacity.
• Most lighting, appliance, tool, and motor loads indicate their
required watts on their nameplate or data plate. For light bulbs,
simply note the wattage rating of the bulb.
• If a load does not show its rated wattage, multiply that load's
rated VOLTS times AMPS to obtain WATTS.
• Induction-type motors (such as, those that run the vehicle's
furnace fan, refrigerator, air conditioner, etc.) need about 2-1/2
time more watts of power for starting than for running (for a
few seconds during motor starting). Be sure to allow for this
when connecting electrical loads to the generator. First, calcu-
late the watts needed to start electric motors in the system. To
that figure, add the running wattages of other items that will be
operated by the generator.
• For the first two or three hours of operation, do not apply electri-
cal loads over 75 percent of the unit's rating.
