2.9.1 REMOTE PANEL MODELS
The remote panels mount a rocker type start/stop
switch, a “Generator Run” advisory lamp and an
hourmeter. The hourmeter should be used in con-
junction with the maintenance operations found in
Part I of this manual.
• Model 004057 includes the remote panel and a 10
foot long, 4 wire harness.
• Model 004184 includes the remote panel and a 30
foot long, 4 wire harness.
3.1 POST INSTALLATION TESTS
The air-cooled generator set was factory tested and
adjusted. You should not be required to adjust the
unit any further except under special circumstances.
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.
2. Check the fuel supply. Gas fuel lines must have
been properly purged and leak tested in accor-
dance with applicable fuel codes. All fuel shutoff
valves in the fuel supply lines must be open.
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 genera-
tor’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 addi-
tional adjustment should be necessary. Only qual-
ified service technicians who have been trained
should perform adjustments outlined in this man-
ual.
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 air-
flow is available. You must not allow the unit to over-
heat during prolonged operation.
NOTE:
The generator engine is equipped with a high tem-
perature 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.
GENERAC RECOMMENDS THAT YOU TEST THE
GENERATOR FOR ADEQUATE COOLING.
