INTRODUCTION
INTENDED USES
This engine generator set has been designed primarily for
portable heavy duty commercial use. Both 120 volt and 240
volt receptacles are provided in the control panel to plug
in your loads (lights, portable tools, and small appliances).
These units are dual wound generators, therefore the
120 volt loads must be equally split with 1/2 of the rated
capacity available on each of the two 120 volt circuits.
This portable unit requires large quantities of fresh air for
cooling the engine and generator. For safety, long life and
adequate performance, these units should never be run in
small compartments without positive fresh air flow.
RESTRICTED USES
DO NOT remove from the cradle assembly. Removal of the
generator from the cradle assembly may cause excessive
vibration and damage to the engine-generator set.
DO NOT operate and/or store the unit outside during
inclement weather without adequate protection from the
elements. Failure to do so will damage the unit.
DO NOT install and operate this generator in a small
compartment, i.e. generator compartments of vehicles,
motor homes or travel trailers. These compartments
will not allow enough free flow of fresh air to reach the
engine generator set for cooling and will cause the unit to
overheat, damaging both the engine and generator. Small
compartments will also develop hot spots where there is
very little air flow and may cause a fire.
PLEASE NOTE There are 3rd party companies making
enclosures for generators that have been properly
engineered. The use of these 3rd party enclosures is
acceptable as long as they have been certified and meet
current code.
DO NOT attempt to operate at 50 cycles. These units are
designed and governed to operate at 60 cycles only.

TESTING POLICY
Before any generator is shipped from the factory, it is fully
checked for performance. The generator is loaded to its
full capacity, and the voltage, current, and frequency are
carefully checked.
Rated output of generator is based on engineering tests
of typical units, and is subject to, and limited by, the
temperature, altitude, fuel, and other conditions specified
by the manufacturer of applicable engines.
