damage or destruction of the equipment and possible
personal injury.
______________________________________________________
1. ELECTRIC SHOCK- The output voltage present in this
equipment can cause a fatal electric shock. This equipment
must be operated by a responsible person.
a. Do not allow anyone to operate the generator
without proper instruction.
b. Guard against electric shock.
c. Avoid contact with live terminals or receptacles.
d. Use extreme care if operating this unit in rain or
snow.
e. Use only three-prong grounded plugs and
extension cords.
f. Be sure the unit is properly grounded to an
external ground rod driven into the earth.
g. Do not make or break electrical connection under
load.
2. FIRE HAZARD- Gasoline, diesel and other fuels always
present a hazard of possible explosion and/or fire.
a. Keep a fire extinguisher nearby and know its
proper use. Fire extinguishers rated ABC by
NFPA are appropriate.
3. DEADLY EXHAUST GAS - Exhaust fumes from any engine
contain carbon monoxide, an invisible, odorless and deadly
gas that must be mixed with fresh air.
a. Operate only in well ventilated areas.
b. Never operate indoors.
4. NOISE HAZARD - Excessive noise is not only tiring, but
continual exposure can lead to loss of hearing.
a. Use hearing protection equipment when
working around this equipment for long periods of time.
b. Keep your neighbors in mind when permanently
installing this equipment.
5. CLEANLINESS- Keep the generator and surrounding area
clean.
a. Remove all grease, ice, snow or materials that
create slippery conditions around the unit.
b. Remove any rags or other material that could
create potential fire hazards.
6. SERVICING EQUIPMENT- All service, including the
installation or replacement of service parts, should be
performed only by a qualified technician.
a. Use only factory approved repair parts.
b. Do not work on this equipment when fatigued.
c. Use extreme caution when working on electrical
components. High output voltages from this equipment
can cause serious injury or death.
d. Always avoid hot mufflers, exhaust manifolds, and
engine parts. They all can cause severe burns instantly.
7. INSTALLATION- Installing a PTO generator is not a “do-ityourself” project. Consult a qualified, licensed electrician or
contractor. The installation must comply with all national,
state, and local codes.
a. Never operate the PTO drive generator without having
it properly mounted to a concrete base or approved trailer.
b. Never connect the PTO generator to an existing
electrical system without installing an isolation transfer switch.
c. Always insure the drive shaft is straight and level
before operating the generator.
8. OPERATION - PTO drive shafts (Tumbling Bars) have
many inherent dangers, extereme caution must be exercised
when using them.
a. NEVER
in operation.
b. Keep all safety guards and shields in place and
securely tightened.
c. Never operate a drive shaft that has been damaged
or had the safety shield removed.
d. Never step over a drive shaft while it is running.
e. Never wear a necktie, loose articles of clothing, or
anything else that can be caught in moving parts.
f. Never try to stop a turndrive shaft with your hand or
your foot.

Description
The WINCO PTO drive generator will provide, depending on
the unit purchased, 120/240V single phase, 120/240V three
phase or 120/208 three phase 60Hz electrical service when
direct-driven. Tractor or vehicle power take-off shafts, can be
used for driving these generators.
person making the delivery make note of the loss or damage
on the freight bill, or sign the consigner’s memo of the loss or
damage. Contact the carrier for claim procedures.
When loss or damage is noted after delivery, segregate the
damaged material, and contact the carrier for claim procedures.
NOTE: The prime mover which drives the generator must be
capable of delivering approximately 2 HP per 1000 watts
output from the generator. 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 load sensing transformer which
provides extra motor starting power, a color coded voltmeter to
warn against high or low voltage, 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 splined, and is 1-3/8 in diameter.
The factory thoroughly tests each of these generators before
shipment. All are continuous duty rated.
IMPORTANT: THE MANUFACTURER STRONGLY RECOMMENDS RUNNING THE GENERATOR UNDER LOAD AT
LEAST ONCE A MONTH IN ORDER TO EVAPORATE ANY
ACCUMULATED MOISTURE CONDENSATION
UNPACKING
CAUTION: Equipment Damage
DO NOT invert generator during unpacking. The Gearcase
contains oil which will leak out if inverted during unpacking.
“Concealed damage” means damage to the contents of a
package which is not evident when the package is delivered
by the carrier, but which is discovered later. The carrier or
carriers are responsible for merchandise lost or damaged in
transit. The title to the goods rests with the consignee when
the goods are shipped FOB factory, and only the consignee
can legally file claims. Two years are allowed in which to file
suit after a claim is disallowed in writing by the carrier.
Assembly
The only assembly work required after unpacking the generator is to assemble and wire the load disconnect plug, which is
contained in a bag in the subpack carton packed in the
generator crate. The bag contains an instruction sheet, a plug
body, three or four brass pins (large pin for neutral line), and a
small envelope. The small envelope contains an allen
wrench, retainer pins, and set screws.
To wire the load disconnect plug, use the following type of
cable:
Generator Size,
Model AWG Insulation
35PTOC-3 1 600V, THW
40PTOC-4 4 600V, Neoprene
45PTOC-17 4 600V, Neoprene
50PTOC-3 1 600V, THW
55PTOC-3 1 600V, THW
75PTOC-4 1 600V, THW
75PTOC-17 1 600V, THW
Unpack the generator as follows:
1. Remove the carton.
2. Examine the unit for damage.
3. Find the small subpack carton packed in the large carton.
Be careful not to throw away the subpack carton with the large
carton.
4. Open the subpack carton and make sure it contains:
a. Generator instruction manual
b. Load disconnect plug (disassembled, in bag)
5. Remove the four bolts which hold down the generator feet
to the pallet.
6. Lift the generator from the pallet by means of the lifting eye
on the top of the generator.
7. Inspect the generator carefully for freight loss or damage. If
loss or damage is noted at time of delivery, require that the

To assemble and wire the load disconnect plug,
proceed as follows (see Figure 1):
1. Cut cables to the required length.
2. Strip off insulation 7/8" back from one end of each cut-tolength cables.
3. Start threading a set screw into each pin.
4. Insert the stripped end of one cable fully into one of the
brass pins, and tighten the set screw firmly to secure the
cable end in the pin.
