3J POST INSTALLATION TESTS

The air-cooled generator set was factoiy tested and

adjusted. You should not be required to adjust the

unit any further except under special circum

stances.

--------

-ik WARNING Mk

----------------

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 START-UP

Before starting, complete the following;

1. Check the engine crankcase oil level and, if nec

essary, fill to the dipstick “FULL” mark (cross-

hatched area) with the recommended oil. Do not

fill above the FULL mark.

Check the fuel supply. Gas fuel lines must have

been properly purged and leak tested in accor

dance with applicable fuel codes. All fuel shut

off valves in the fuel supply lines must be open.

-A

DANCER

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 leakage

is permitted. You must be sure no gasoline fuel

vapors enter the vehicle interior.

3.3 INITIAL START

When you are 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, Section 2.5, “Starting the

Generator” (Page 8), 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 Section 3.4.

Run the unit at least 30 minutes with loads

applied.

6. Turn off all electrical loads by setting the gener

ator’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 tempera

tures. Then, shut down the engine.

NOTE:

The generator set was thoroughly tested and

adjusted at the factory before shipping. No addi

tional 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 per

cent 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. You must 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 temper

ature is too high, switch contacts close, and the

engine shuts down automatically.

GENERAC RECOMMENDS THAT YOU TEST THE

GENERATOR FOR ADEQUATE COOLING.
