ELECTRICAL LOADS AND GUIDELINES
Your generator set is designed to power electrical
apparatuses within the electrical power output limitations
of the generator. Please note that any generator overload
can cause serious problems/damage to your generator.
Additionally, apparatuses with electrical motors can
require higher wattage requirements at start-up than when
running. Some electric motors require as much as 2.5
times the rated wattage at start-up. Although the start-up
wattage requirements for electric motors lasts only a few
seconds, great care must be taken in connecting loads to
your generator so as not to overload the generator. Refer
to the label on each electrical apparatus to determine the
wattage requirements of that apparatus. THE TOTAL
WATTAGE REQUIREMENTS OF ALL POWERED
APPARATUSES (INCLUDING START-UP LOADS)
MUST NEVER EXCEED THE CONTINUOUS RATING
OF YOUR GENERATOR, CORRECTED TO THE
ACTUAL ENVIRONMENTAL CONDITIONS AT THE
OPERATING SITE.
As a reference only, Table 1 below shows some general
wattage requirements for several common electrical
devices. This chart is intended as a guide only. The actual
total wattage should be determined by referring to the
actual labels on each of the powered electrical devices.

GENERATOR DESIGNED
PERFORMANCE GUIDELINES
This electrical generator is designed to produce electrical
energy for the purpose of powering lights, power tools,
appliances and motor loads within the intended design
constraints of the generator. The generator is designed to
produce single-phase electrical power at 120 or 120/ 240
VAC. This generator is not intended for installation in RV
or motorhome applications. The Performance
Specifications for your generator are listed in Table 2
Performance Specifications.

ENGINE LIMITATIONS ON GENERATOR
PERFORMANCE
Generator ratings assume 60
F (20C) and Sea Level.
Operation of your generator at temperatures above 60
F
(20C) or above Sea Level will result in lower electrical
output. Electrical output must be derated 2% for each 9
F
above 60
F and 3 ½ % for each 1000 feet above mean
sea level.
