INTRODUCTION
The WINCO power take-off generators are designed primarily for farm
use as a standby electrical power supply, utilizing the power take-off
of a tractor or truck as the prime mover. This PTO drive generator will
provide, 120/240V 1-PH, 120/208V 3-PH, 120/240V 3-PH, or 277/480V
3-PH (depending on model), 60Hz electrical service when properly
driven.
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.
NOTE:
It is acceptable to use this generator with a tractor with less HP
output than required for full power operation. The generator will work
but produce only as much kW output as the tractor can supply HP
for. For example, a 20 HP output tractor will deliver a maximum of
approximately 10 kw.
If you are using a tractor with more HP than required to run the
generator care should be taken to ensure that you do not overload the
generator causing overheating and equipment damage. Observe input
RPM specifications.
The generator may be foundation mounted for use as standby power
source, or trailer mounted, and used as portable electrical power
sources for areas where commercial power is not readily available,
such as out buildings.
This generator includes a frequency meter to warn against high or
low frequency, three output power receptacles, an overload protection
circuit, and an electronic excitation circuit. To reduce maintenance
problems, the coupling between the generator input shaft and rotor
consists of precision helical gearing rather than a chain link drive. The
input shaft is a 1 3/8in. 6-spline.
IMPORTANT: THE MANUFACTURER STRONGLY RECOMMENDS
RUNNING THE GENERATOR UNDER LOAD AT
LEAST ONCE A MONTH IN ORDER TO EVAPORATE ANY
ACCUMULATED MOISTURE CONDENSATION.
TESTING POLICY
Before any generator is shipped from the factory, it is fully checked for
performance. The generator is loaded, 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.
PREPARING THE UNIT
UNPACKING
CAUTION: EQUIPMENT DAMAGE
When you unpack your new generator, be sure to remove all of the
information sheets and manual from the carton.
1. As you receive your unit, it is critical to check it for any damage. If
any damage is noted, it is always easiest to refuse the shipment and
let WINCO take care of the freight claim. If you sign for the unit, the
transfer of the ownership requires that you file the freight claim
2. Before proceeding with the preparations of your new generator
for operation, take a couple of minutes to ensure the unit you have
received is the correct model and review the specification pages in
this manual to ensure that this unit meets your job requirements.
