Dayton Professional-
Duty Electric Generators
Description
Dayton professional-duty generators are rugged and compact to provide dependable,
trouble-free service. The alternators are brushless with revolving fields. Honda gasoline
engines provide long life under heavy use. Overhead valves (OHV) provide high perfor-
mance with lower fuel consumption. These engines are governed to maintain engine
speed of 3600 RPM under load. 3600 RPM engine speed provides 120/240V, 60 Hz
power. Additional features include circuit breaker protection, spark-arresting muffler
(except Model 3WY47), large fuel tank, and oil alert system. Models 3WY45, 3WY46,
and 3WY47 include electric starter.

General Safety Information Store fuel in approved container.
Store fuel in a well-vented area free
of open flames or sparks.
Engine exhaust
contains poisonous
carbon monoxide gas. Overexposure
will cause loss of consciousness and
will lead to death. Use only in well-
vented areas. Make sure area has
plenty of free-moving, fresh, outside
air. Never run generator in an enclosed
or confined area. Never run generator
inside occupied building.
Early signs of carbon monoxide
poisoning resemble the flu, with
headaches, dizziness, or nausea. If you
have these signs, get fresh air at once!
Some people are more affected by
carbon monoxide than others. These
include pregnant women, persons with
heart or lung disease or anemia, those
under the influence of alcohol, and
those at high altitudes.
Gasoline presents
a hazard of fire or
explosion. Gasoline is flammable. Its
vapor is explosive.
Keep fuel out of children’s reach.
Refuel generator in a well-vented
area. Do not fill fuel tank in the dark.
Do not refuel while engine is
running. Unhook all electrical loads
and shut off engine before refueling.
Do not overfill fuel tank. Always
allow room for fuel to expand. If you
overfill tank, fuel can overflow onto
hot generator or engine surface. This
can cause fire or explosion. After
refueling, tightly close fuel tank cap.
Do not spill fuel. Fuel or fuel vapor
may ignite. If fuel spills, make sure
area is dry before starting engine.
Never smoke in refueling area. Never
allow open flames or sparks in area.
Guard against fire
hazard. Keep
operation area well-vented. Keep
generator at least three feet away

Generator Features
OIL ALERT SYSTEM
The oil alert system protects the engine
from low oil damage. This system auto-
matically shuts down the engine and
prevents engine restarting if the oil level
falls too low.
NOTE: When this happens, the engine
switch remains in the ON position. The oil
alert system is wired into the ON/OFF
switch.
If this system shuts down the engine, the
engine will not start until you add oil. Add
oil to engine (see "Engine Oil", page 10).
NOTE: Operate generator on a level
surface. If not level, the oil may flow away
Engine exhaust
from this product
contains chemicals known, in certain
quantities, to cause cancer, birth
defects, or other reproductive harm.
Guard against
burns. Hot engine
parts can cause severe injury. Use
caution and remain alert when using
generator.
Keep children and animals away
from generator while it is running or
hot.
Keep all covers and shields in place.
Keep them tightly secured.
The muffler becomes very hot during
operation. The muffler remains hot
for a while after shutdown. Do not
touch muffler while it is hot. Do not
let muffler touch anything flam-
mable. Let engine cool before
transporting or storing.
Have standby
installation to
home or building performed by a
licensed electrician. Do not let anyone
else wire into a utility circuit. Personal
injury, equipment damage, or damage
to home could occur.
Never connect
generator to any
existing electrical circuits. The genera-
tor output will back-feed into the
utility power line. This may electrocute
a power company line repair person.
Also, if generator is powering electri-
cal circuits, the chance of an electrical
fire exists.
Battery gives off
explosive gases.
Keep sparks, flames, and cigarettes
away. Do not remove or install battery
cables when engine is cranking or
running. Only service or use battery in
a well-vented area.

information.
FULL POWER SELECTOR SWITCH
All models except 3W735B, 3WY47, and
3WY45 have a full power selector switch
on the control panel. The switch has two
positions: 120 VOLT ONLY, and 120/240
VOLT.
120 VOLT ONLY: This position sends full
power to the 120V receptacles only. 240V
power is not available. Use this position
when powering 120V items only.
Figure 5 – Full Power Selector Switch in 120
Volt Only Position
120/240 VOLT: This position sends full
power to the 120/240V receptacle. It also
powers the 120V receptacles at reduced
wattage capacity.
Figure 6 – Full Power Selector Switch in
120/240 Volt Position
IMPORTANT: Do not move the full power
selector switch while powering electrical
items. Unplug all items before moving
switch. Failure to do so can damage
switch.
Models 3W735B, 3WY45, and 3WY47 do
not have this switch. These models provide
full power to all receptacles.
HOUR METER
All models except 3W735B have an hour
meter. The hour meter is on the control
panel. The hour meter shows the total
generator run time, including all idle time
(See Figure 7). Hour meter is accurate up
to 1/10 of an hour.
AUTO-IDLE SYSTEM
The auto-idle system allows the engine to
idle down or run at a slower speed when
the generator is not being used to supply
power. The auto-idle system can be turned
ON or OFF by a rocker switch on the
control panel. When the switch is in the
OFF position, the engine runs at full speed
all of the time. When the switch is in the
ON position, the engine slows down to
idle speed until an electrical load is
applied. When a load is applied to the
generator (an electrical item is plugged in
and turned on) the engine speeds up to
the preset speed required to produce the
correct voltage.
IMPORTANT: A minimum current load of
1 Amp is required to disengage the auto
idle solenoid and cause the engine to
come up to speed for correct voltage.
Figure 7 – Hour Meter
GROUND FAULT CIRCUIT INTER-
RUPTER RECEPTACLE
All models have a 120-volt ground fault
circuit interrupter (GFCI) receptacle. The
GFCI receptacle is on the control panel or
top cover of alternator (Model 3W735B
only). The GFCI protects you against
hazardous electrical shock caused when
your body becomes a path through which
electricity travels to reach ground. This
could happen when you touch an appli-
ance or cord that is ‘live’ through faulty
mechanism, damp or worn insulation, etc.
When protected by the GFCI, you may still
feel a shock, but the GFCI should cut it off
quickly. A person in normal health should
not receive serious injury.
NOTE: Infants and very small children may
still be affected.
TEST PROCEDURE
Check the GFCI receptacle every month.
This insures it is working right.
1. Push black TEST button. Red RESET
button should pop out. This should trip
GFCI, resulting in no electrical power at
receptacle. Verify this by plugging test
lamp with good bulb into receptacle. If
lamp does not work, GFCI receptacle is
good.
Powering items at reduced engine speed
will damage generator and powered
items.
ELECTRIC START (MODELS 3WY46,
3WY45, AND 3WY47 ONLY)
Models 3WY46, 3WY45, and 3WY47 have
an electric starter. A battery is not supplied
with generator. You must provide a 12-
volt, 32-amp-hour battery. For more
battery information, see “Battery,” page 8.

Model 3W735B has only one receptacle
circuit breaker. All other models have four,
except Model 3WY47 which has six. The
circuit breakers protect the receptacles and
alternator. Overloading generator will trip
circuit breaker. A short circuit in item
being powered will also trip breaker. If this
occurs, unplug electrical load from
receptacle. Let circuit breaker cool down.
Push circuit breaker button to reset.
Generator Features
(Continued)
Electric motors need higher starting
current. They require up to 3 to 6-times
their rated full-load wattage to start. The
starting current needed may be too high.
This can cause nuisance circuit breaker
tripping. To help prevent this, start electric
motors first. Connect additional items to
generator after starting motors. If this
continues to happen, reduce the total
generator load.
NOTE: High ambient temperatures will
cause nuisance tripping.

Follow steps below to check oil level.
Make sure engine is level and stopped.
1. Remove dipstick (See Figure 19). Wipe
dipstick clean.
2. Insert dipstick into oil filler neck. Do not
screw it in. Oil level should be at top of
filler neck. Oil should cover most of
dipstick. For Model 3WY47 only, oil level
should be between two dots on dipstick.
3. If level is low, fill to top of oil filler neck
(See Figure 19). Only use oil recommended
in engine owner’s manual. For Model
3WY47 only, fill to top dot on dipstick.

VENTILATION
Use only in well-
vented areas. Make
sure area has plenty of free-moving,
fresh, outside air. Never run generator
in an enclosed or confined area. Never
run generator inside occupied building.
Engine exhaust contains poisonous
carbon monoxide gas. Overexposure
will cause loss of consciousness and
will lead to death.
This generator needs cooling air to run
properly. Never block free-flowing, cooling
air to generator. Overheating will occur
without cooling air. This will damage the

generator before starting. This will
help guard against deadly electric
shock. Only use grounded plugs with
generator. Only use grounded exten-
sion cords. Only use three-wire or
double-insulated power tools.
Grounding generator helps prevent electric
shock from a ground fault condition.
Locate ground lug on end of generator
housing (See Figure 20). Attach a #10
stranded-copper ground wire to ground
lug. Drive grounding point into ground.
Grounding point can be a stake, ground-
ing rod, or pipe. Grounding point should
be copper or brass. Attach ground wire to
grounding point. You must supply the
ground wire and grounding point. These
do not come with generator. Follow the
National Electrical Code and all state and
local codes. Consult your power company
or a licensed electrician.

STANDBY INSTALLATION TO HOME
OR BUILDING
Have standby
installation
performed by a skilled, licensed
electrician. Do not let anyone else wire
into a utility circuit. Personal injury,
equipment damage, or damage to
home could occur.
IMPORTANT: This generator will not
power your entire home. Most home
utility electric service is more than 60
amps. This will exceed generator output.
Only power needed items during a power
outage. Make sure total wattage of
electrical load does not exceed rated
wattage of generator.
You can use this generator as a standby
power source. During a power outage, the
generator will power selected items in a
building. Have generator and additional
wiring installed by a skilled, licensed
electrician. This is not a do-it-yourself job.
Follow all local codes.
The electrician must
install a double-
throw transfer switch. This isolates
existing electrical circuits from the
utility power line. If not isolated,
generator output will back-feed into
utility power line. This may electrocute
a power company line repair person.
construction sites, you must use a GFCI.
United States OSHA and the National
Electric Code requires this.
You may need to provide the GFCI device.
Purchase GFCI at any electrical supply
house. Check the Yellow Pages for the
nearest supply house.
DUST, DIRT, RAIN, AND SNOW
Do not use
generator out-
doors in rain or snow. Do not use
generator near standing water or
snow. Do not use if generator is wet or
damp. Operating generator in these
conditions increases the risk of electro-
cution. Severe injury or death can
occur.
Do not use generator in extremely dusty or
dirty conditions. This will severely affect its
life. Keep generator clean. Do not allow
dust, dirt, rain, or snow to collect on it.
Protect generator from outdoor elements.

DETERMINING ELECTRICAL LOAD
FOR GENERATOR
You must decide what electrical load your
generator can power. Do this before using
generator. Use the following four-step
method. It will help you select a load that
is not too large. Make sure total wattage
of all electrical loads does not exceed
rated wattage of generator. For rated
wattage of your generator, see “Electrical
Specifications,” page 2. Electric motors
present a special problem when figuring
load. Read Step 3 carefully.
1. Make two lists of items you want
powered by generator. List all motors
and motor powered appliances in one.
List all lights, small appliances, etc. in
the other. For standby service to home
or building, only include items you must
power.
2. Enter running watts of each item except
motors. The light bulb or appliance
nameplate lists its wattage. Remember,
1KW = 1000 watts.
NOTE: The nameplate may not list
wattage. It may only list volts and amps.
The formula for finding wattage is: Volts x
Amps = Watts. For example: An appliance
nameplate states 3 amps at 120 volts. 3
amps x 120 volts = 360 watts.
3. Electric motors present a special
problem. They require 3 to 6 times their
rated full load wattage to start. Chart 1,
on page 12, shows starting watts
(maximum volt-amperes [VA]) for
different size motors. For example: an
electric motor nameplate states 5 amps
at 120 volts. 5 amps x 120 volts = 600
watts running. Multiply this figure by 3.
This will show the starting watts
(maximum VA) needed. 600 watts x 3 =
1800 watts (VA) to start. When figuring
the generator load for motors, you must
use the starting watts (maximum VA)
figure. Do not use the running watts
figure.

NOTE: Some motors require nearly the
same wattage to run as to start. These
items include saws, drills, hair dryers, and
food mixers. See Chart 2 for typical
appliance wattage examples.
4. Add watts and starting watts (maximum
VA) of all items. This total must not be
larger than the rated wattage of your
generator. It is a good idea to have up
to 25% extra capacity for future needs
or extra equipment.

See engine owner’s manual for details.
ADDING ELECTRICAL LOADS
IMPORTANT: Do not overload generator.
Make sure total wattage of all electrical
loads does not exceed rated wattage of
generator. Overloading may shorten
generator life. It could also cause internal
damage to generator. Overloading
will trip circuit breaker.
IMPORTANT: Keep full power selector
switch in the 120 VOLT ONLY position if
only powering 120V items. Only move
switch to 120/240 VOLT position if
powering 240V items.
1. Check items to be powered. Their
nameplate lists their wattage ratings.
NOTE: The wattage ratings for some
electrical motors are misleading. They may
require 3 to 6 times their rated wattage to
start. You must figure total electrical load
wattage. Make sure total wattage of all
electrical loads does not exceed rated
wattage of generator. See “Determining
Electrical Load for Generator,” page 11.
2. Start engine. Let engine reach full
speed.
3. Connect electrical loads one at a time. If
the load consists of electric motors, start
them first. Always start the largest first.
Start each motor individually.
DISCONNECTING ELECTRIC LOADS
Remove electrical loads one at a time.
Remove voltage sensitive items first.
Voltage sensitive items include TVs, VCRs,
and other home electronic items.
STOPPING ENGINE
IMPORTANT: The engine speed is preset.
The throttle is locked in preset position. Do
not adjust throttle.
Follow the steps below to stop engine.
1. Remove all electrical loads from
generator (See “Disconnecting Electrical
Loads,” above). Remove electrical loads
one at a time.
2. Let engine run for two or three minutes
after removing electrical loads. This lets
engine cool slightly.
3. Turn engine switch to the OFF position
(See Figures 33 and 34).
Always set the idle
speed before
turning on the auto-idle. If idle speed
is not set, the larger resistor on the
control board may become hot. Heat
from the resistor may damage the
protective coating on the control
board.
5. Slowly pull solenoid bracket away
from engine (on Model 3WY47 this
will require bending the bracket
slightly).
6. With a volt meter, check the no-load
output voltage at the 120-volt duplex
receptacle. At proper idle speed (2680
minimum RPM) the meter should read
50-60 volts. Lower settings will cause
the auto-idle to not operate properly.
7. After reaching proper idle speed,
tighten M8 nut to secure solenoid
mounting bracket (Models 3WY46
and 3WY45 only).
8. Turn auto-idle switch ON. Make sure
solenoid is engaged. When engaged,
the plunger is pulled back into the
solenoid.
9. If the engine speed is too slow, the
engine will want to "hunt" or speed
up and slow down repeatedly. When
this occurs, increase engine speed by
adjusting throttle stop screw on
carburetor (refer to Carburetor
Adjustment in Honda Engine Manual).
10. Replace the engine linkage cover
(Models 3WY46 and 3WY45 only).

Dayton Professional-Duty
Electric Generators
LIMITED WARRANTY
DAYTON FIVE-YEAR LIMITED WARRANTY. Dayton Professional-Duty Electric Generators, Models covered in this manual, are
warranted by Dayton Electric Mfg. Co. (Dayton) to the original user against defects in workmanship or materials under normal use
for one year after date of purchase. Any part which is determined to be defective in material or workmanship and returned to an
authorized service location, as Dayton designates, shipping costs prepaid, will be, as the exclusive remedy, repaired or replaced at
Dayton’s option. For limited warranty claim procedures, see PROMPT DISPOSITION below. This limited warranty gives purchasers
specific legal rights which vary from jurisdiction to jurisdiction.
LIMITATION OF LIABILITY. To the extent allowable under applicable law, Dayton’s liability for consequential and incidental damages
is expressly disclaimed. Dayton’s liability in all events is limited to, and shall not exceed, the purchase price paid.
WARRANTY DISCLAIMER. Dayton has made a diligent effort to provide product information and illustrate the product in this literature
accurately; however, such information and illustrations are for the sole purpose of identification, and do not express or imply a warranty that
the products are MERCHANTABLE, or FIT FOR A PARTICULAR PURPOSE, or that the products will necessarily conform to the illustrations or
descriptions.
Except as provided below, no warranty or affirmation of fact, expressed or implied, other than as stated in “LIMITED WARRANTY” above
is made or authorized by Dayton.
PRODUCT SUITABILITY. Many jurisdictions have codes and regulations governing sales, construction, installation, and/or use of products
for certain purposes, which may vary from those in neighboring areas. While Dayton attempts to assure that its products comply with such
codes, it cannot guarantee compliance, and cannot be responsible for how the product is installed or used. Before purchase and use of a
product, review the product applications, and all applicable national and local codes and regulations, and be sure that the product, installa-
tion, and use will comply with them.
Certain aspects of disclaimers are not applicable to consumer products; e.g., (a) some jurisdictions do not allow the exclusion or limitation
of incidental or consequential damages, so the above limitation or exclusion may not apply to you; (b) also, some jurisdictions do not
allow limitations on how long an implied warranty lasts, consequently the above limitation may not apply to you; and (c) by law, during
the period of this Limited Warranty, any implied warranties of implied merchantability or fitness for a particular purpose applicable to
consumer products purchased by consumers, may not be excluded or otherwise disclaimed.
PROMPT DISPOSITION. Dayton will make a good faith effort for prompt correction or other adjustment with respect to any product
which proves to be defective within limited warranty. For any product believed to be defective within limited warranty, first write or call
dealer from whom product was purchased. Dealer will give additional directions. If unable to resolve satisfactorily, write to Dayton at
address below, giving dealer’s name, address, date and number of dealer’s invoice, and describing the nature of the defect. Title and risk of
loss pass to buyer on delivery to common carrier. If product was damaged in transit to you, file claim with carrier.
