3.1 POST INSTALLATION TESTS
The generator set was factory-tested and adjusted. It is not neces-
sary to adjust the unit any further, except under special circum-
stances.

Do not make any unnecessary adjustments.
Factory settings are correct for most applica-
tions. When making adjustments, however,
be careful to avoid overspeeding the engine.
3.2 BEFORE INITIAL STARTUP
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. 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.
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
line breakers to their “OFF” (or open) position.
2. Refer to Part I, the “Starting the Generator” section, for crank-
ing and starting instructions. The engine may require more
cranking for initial starting, since the fuel lines have to be
primed (use of the preheat switch will operate the generator’s
electrical fuel pump and 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 the "Testing Under Load" section. Run the unit at
least 30 minutes, with loads applied.
6. Turn off all electrical loads by setting the generator’s line
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.

The generator set was thoroughly tested and
adjusted at the factory before shipping. No
additional adjustment should be necessary.
Only trained, qualified service technicians
should perform adjustments outlined in this
manual.
3.4 TESTING UNDER LOAD
Apply electrical loads equal to about 50 to 75 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 coolant tem-
perature switch. The switch has normally open (N.O.) contacts.
When the engine coolant temperature is too high, switch con-
tacts close, and the engine shuts down automatically.
THE MANUFACTURER RECOMMENDS THAT THE GENERATOR BE
TESTED FOR ADEQUATE COOLING.
