3.1 POST INSTALLATION TESTS
The air-cooled generator set was factory tested and adjusted. It
should not be required to adjust the unit any further except under
special circumstances.
n
Do not make any unnecessary adjustments.
Factory settings are correct for most appli-
cations. When making adjustments, however,
be careful to avoid overspeeding the engine.
3.2 BEFORE INITIAL START-UP
Before starting, complete the following:
1. Check the engine crankcase oil level and, if necessary, fill to
the dipstick “FULL” mark (cross-hatched area) with the rec-
ommended oil. Do not fill above the FULL mark.
2. Check the fuel supply. Gas fuel lines must have been properly
purged and leak tested in accordance with applicable fuel
codes. All fuel shutoff valves in the fuel supply lines must be
open.
n
If a liquid propane (LP) gas fuel system has
been installed, it must be properly tested for
leaks before operating the system in compli-
ance with ANSI A119.2/NFPA 501C. No leak-
age is permitted. Be sure that no gasoline
fuel vapors enter the vehicle interior.
3.3 INITIAL START
When absolutely certain that the unit has been properly installed
and prepared for use, start the engine as follows:
1. Turn off all electrical loads. Do this by setting the generator’s
main circuit breakers to their “OFF” (or OPEN) position.
2. Refer to Part I, “Starting the Generator”, for cranking and
starting instructions. The engine may require more cranking
for initial starting since the fuel lines have to be primed (use
of the primer switch will shorten this time).
3. Let the engine warm up for about five minutes to allow internal
temperatures to stabilize.
4. Carefully inspect the engine/generator for fuel, oil and exhaust
system leaks. Before proceeding to the next step, correct any
leakage immediately.
5. When all tests and adjustments at no-load are completed,
apply electrical loads and check for proper operation under
load (see "Testing Under Load"). Run the unit at least 30 min-
utes with loads applied.
6. Turn off all electrical loads by setting the generator’s main
circuit breakers to their “OFF” (or OPEN) position.
7. Let the unit run at no-load for a few minutes to stabilize
internal engine/generator temperatures. Then, shut down the
engine.
NOTE:
The generator set was thoroughly tested and adjusted at the
factory before shipping. No additional adjustment should be
necessary. Only qualified service technicians who have been
trained should perform adjustments outlined in this manual.
3.4 TESTING UNDER LOAD
Apply electrical loads equal to about 75 to 100 percent of the unit's
rated wattage/amperage capacity.
Let the unit run at least 30 minutes with load applied. During this
part of the test, check that the unit is not running excessively hot
and that adequate cooling airflow is available. Do not allow the unit
to overheat during prolonged operation.
NOTE:
The generator engine is equipped with a high temperature
switch. The switch has normally closed (N.C.) contacts. When
the engine temperature is too high, switch contacts close, and
the engine shuts down automatically.
THE MANUFACTURER RECOMMENDS THAT THE GENERATOR
BE TESTED FOR ADEQUATE COOLING.
