INITIAL START UP
Use the following checklist to verify the correct preparation
of the engine generator before starting.
On All Units Check:
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 these generators 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. See
“Operating Speed” section for additional information.
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. Position #I will turn on the
fuel solenoid and position #II will engage the starter.
The switch is spring loaded to the #I position, so when
you release the key the switch returns to this position.
Once the engine is started the only way to reengage the
starter if the engine should stop is to rotate it to the O
position and then back to the #I and #II position. The
engine has a built in lockout that prevents the starter
from being engaged once the unit has started.
c. The engine will start and come up to operating
speed. Light number 1 should light up at this point to
indicate the unit is operating properly.
d. To shut the unit off rotate the key switch to the O
position and 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 Manufacturers 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 book are approximately as
follows, under varying loads:
