INTRODUCTION
PRODUCT DESCRIPTION
The engine-generator set consists of a multi-cylinder, liquid-
cooled engine nominally operating at 1800 RPM. This
generator set meets current EPA regulations for standby
use only. The generator frequency regulation is maintained
by the engine mechanical governor to /- 1.5 Hertz.
The generator is connected to the engine flywheel via
flexible drive disks. The generator set is skid mounted with
isolation mounts between the engine and base.
NOTICE:
A Customer supplied 12 Volt battery is required to complete
the installation. Battery requirements are listed later under
the battery installation section.
The generator ships with an advanced DSE7310 digital
controller. The DSE7310 will electronically display useful
engine and generator performance information. The
controller starts and stops the generator and monitors
critical operating parameters and will shut the generator
down to protect the engine from damage.
GENERATOR SET:
Every WINCO generator set has its own unique identity
data plate. This data plate identifies the complete unit
model number, the system serial number, and has links to
the individual components that form the generator set in
our factory records. Several of the major components also
have their own individual data plates providing additional
information to document build data for warranty and
replacements parts. Be sure to have the main WINCO unit
data plate information recorded inside the front cover
of this manual for future reference and for identification
whenever requesting field or factory assistance.
Primary fields needed for assistance are complete model
number and serial number.
ENGINE:
This manual covers specific operation of the combined
engine generator set. The basic engine information
provided in this manual is not suitable for all operating
conditions. Refer to the engine operators manual for more
detailed operation and maintenance information.
CAUTION: EQUIPMENT DAMAGE:
Be sure to check the engine oil level frequently as specified
in the engine manual.

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.
