1. Engine oil, fill as required with correct grade and
quantity.
2. Connect and prime the fuel line. The electric fuel pump can be
used to fill the line and prime the injector pump. DO NOT RUN
THE ENGINE UNTIL THE NEW FUEL LINE HAS BEEN FULLY
PRIMED. Air in the fuel line can be difficult to remove. Avoid the
problem by checking the fuel prime before initial start or after fuel
system service (replacing fuel filter, fuel lines etc.) The engine
requires clean, fresh fuel.
3. Visually check unit for loose parts.
STARTING and STOPPING
The throttle control on this generator is preset and locked to
operate at 3600 RPM (nominal) with no load speed set at 3690
RPM. Only a trained service technician should be allowed to
adjust this speed setting.
1. Manual starting - Provision for manual starting is not provided -
If the battery is dead or defective, recharge or replace it. Refer to
the engine manual for additional starting, operating, and stopping
instructions.
2. Electric Starting - Always keep the battery charged, but
especially during cold weather operation.
a. Turn on the fuel supply and prime the fuel line up to the
injector pump.
b. Operate the key switch. In the run position the switch will
turn on the fuel solenoid and the fuel pump and in the start
position the starter engage. The switch is spring loaded to the
run position, so when you release the key the switch returns to
this position
CAUTION: EQUIPMENT DAMAGE
DO NOT ENGAGE THE STARTER FOR LONGER THAN 15
SECONDS. DO SO MAY DAMAGE THE STARTER.
c. The engine will start and come up to operating speed.
d. To shut the unit off rotate the key switch to the OFF position.
The unit is stopped by shutting off the fuel solenoid
STARTING HINTS
1. Cold weather.
a. Use the proper oil for the temperature expected.
b. Use fresh winter grade fuel. Winter grade fuel is
blended to improve starting. Do not use old or straight
summer blend fuel.
CAUTION: EQUIPMENT DAMAGE
Never use ether or any other starting aides. Serious engine
damage or personal injury may result from ignoring this simple
warning.
2. Hot weather
a. Be sure to use the proper oil for the temperature
expected.
b. Use only summer blended fuel. Using old fuel left
over from winter may cause damage to the engine or clogging
of the fuel filters and injection pump. See Engine Manufactur
ers instructions.
OPERATING SPEED
The engine-generator must be run at the correct speed in order to
produce the proper electrical voltage and frequency.
CAUTION: EQUIPMENT DAMAGE
The output voltage should be checked to insure the generator is
working properly prior to connecting a load to the generator.
Failure to do so could result in damage to equipment plugged into
the unit and possible injury to the individual.
All engines have a tendency to slow down when a load is applied.
When the electrical load is connected to the generator, the
engine is more heavily loaded, and as a result the speed drops
slightly. This slight decrease in speed, together with the voltage
drop within the generator itself, results in a slightly lower voltage
when the generator is loaded to its full capacity than when
running no load. The slight variation in speed also affects the
frequency of the output current. This frequency variation has no
appreciable effect in the operation of motors, lights and most
appliances. However, electronic equipment and clocks will be
affected if correct RPM is not maintained. See Load vs. Output
chart.
Although individual units and models may vary slightly, the
normal voltage and frequency of the engine-generators described
in this manual are approximately as follows, under varying loads:

*Portion of plant’s rated output current.
The speed of the engine was carefully adjusted at the factory so
that the generator produces the proper voltage and frequency.
For normal usage, the speed setting should not be changed. If
the generator is being run continuously on a very light load, it is
often advisable to lower the operating speed slightly. Whenever
making any speed adjustments check the unit with a voltmeter or
tachometer and be sure the speed is correct.
