KD1800/KD6 FAMILIARIZATION
Generator
Housed within the KD1800/KD6 generator package is a
Marathon Model 332, 6,000 watt (6-KW) generator. This
generator can provide up to 50 amps of current. In addition
two voltage output receptacles have been provided on the
generator's control box . One receptacle has an output of
120/250 VAC and the other is a 120 VAC, GFCI protected
receptacle.
The Marathon Model 332 generator should only be operated
at a frequency of 60 hertz. The speed should be 1,850 rpm's
(no load) and 1,800 rpm's (full load). A single capacitor is
used to regulate the voltage to within 5% of the rated load.
The engine-generator set must be installed in a protected
environment, with a minimal exposure to fumes, moisture,
dust and dirt.
When operating the generator, remember the
outside air temperature must not exceed
40° ° ° ° ° C (104° ° ° ° ° F).
Remember the following when using the generator:
DO NOT obstruct the generator's intake and outlet
passages.
ALWAYS provide sufficient air circulation around the
generator to remove engine heat and to provide ample
generator cooling.
HOT AIR from the radiator must not enter into the
generator.
Use extreme caution when handling capacitors. A
potential shock condition exist even when the engine
has been shut-off. See maintenance section of this
manual for the proper handling of capacitors.
For operation at high altitudes , ratings must be derated
2% for each 1000 feet above sea level.
Frame temperatures above 60

After running the generator for 30 minutes at full load
check the temperature rise. If the temperature is
excessive, examine the generator for the following:
A. Obstructed air-flow
B. Hot air feeding into the inlet of the generator.
C. By-passed air (air not pulled through
generator)

Engine
The KD1800/KD6 is powered by vertical, water-cooled, 4-
cycle diesel engine. This engine is designed to meet every
performance requirement for the generator.
ALWAYS perform a maintenance
check list before starting the engine.
Reference Tables 1 and 2 for generator and engine
specifications.
Refer to the engine maintenance
section for more information about
the engine.
Figure 2 (page 16) shows the basic components and
indicators for the KD1800/KD6 generator.
