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.
Electric motors need higher starting
current. They require up to 3-times their
rated 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.

ENGINE LUBE OIL
Nothing affects the performance and
durability of your engine more than the
lube oil you use. Using inferior oil or not
changing oil regularly increases the risk of
piston seizure, piston ring sticking, and
accelerated wear of cylinder liner, bearing
and other moving parts. Your engine life
may be seriously shortened. Yanmar
recommends CC/CD oil of API engine
service classification, stock number 4ZF20.
Always use oil with the right viscosity for
the ambient temperature in which you are
using the engine. Use the chart below
when choosing your engine oil.
VENTILATION
Use only in wellvented areas. Make
sure area has plenty of free-moving,
fresh, outside air. Never run generator

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.
GROUND FAULT PROTECTION
Ground Fault Circuit Interrupter (GFCI)
helps guard against electric shock. On
construction sites, you must use a GFCI.
OSHA and the National Electric Code
requires this.
You must provide the GFCI device.
Purchase GFCI at any electrical supply
house. Check the Yellow Pages for the
nearest supply house.
STANDBY INSTALLATION TO HOME OR
BUILDING
Have standby

performed by a skilled, licensed
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
3000 watts (model 3ZC06B) or 5000 watts
(model 4W315B). 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.
10
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 up to 3-times
their rated wattage to start. Chart 2,
page 11, 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 1, page 11
for typical appliance wattage examples.
4. Add watts and starting watts (maximum
VA) of all items. This total must not be
larger than 3000 watts (model 3ZC06B)
or 5000 watts (model 4W315B). It is a
good idea to have up to 25% extra
capacity for future needs or extra
equipment.

Operation
HIGH AND LOW TEMPERATURE
OPERATION
Air temperature affects generator output.
Output drops 1% for each 10° temperature rise above 60° F. Very low temperatures may make the engine hard to start.
See engine owner’s manual for more
information.
GENERAL INFORMATION
This generator is not large enough to
power your entire home. Do not connect
generator to any existing electrical circuits.
Plug items directly into generator receptacles. Do not exceed amperage rating of
receptacles. Only use grounded cords.
Use only in wellvented 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.
Never connect
generator to any
existing electrical circuits. The generator output will back-feed into the
utility power line. This may electrocute
a power company line repair person.
Also, if generator is powering electrical circuits, the chance of an electrical
fire exists.
NOTE: We supply the engine owner’s
manual with generator. Refer to that
manual for questions concerning engine
operation.
Use receptacles properly. Improper use
could damage generator. Use only
grounded extension cords. Power only
grounded or double-insulated items. Do

output. Clean fuel filter every six months
or 500 hours operation. Replace fuel filter
every year or 1000 hours operation.
HOW TO CHANGE YOUR ENGINE OIL
2. loosen the nuts of the fuel cock and pull
out the filter from the fuel tank filler
port. Wash the filter thoroughly with
diesel fuel.
Remove the oil filler cap. Remove the drain
plug and drain the old oil while the engine
is still warm. The plug is located on the
bottom of the cylinder block. Tighten the
drain plug and refill with the recommended oil. (See the section under
Preparations for starting in the engine
owner’s manual.)
CLEANING THE OIL FILTER
Yanmar engine servicing should be
handled by your nearest authorized
Yanmar engine service firm. Contact
Yanmar at 1-714-630-9415 for nearest
authorized Yanmar engine service firm.
Loosen the fixing bolt and then pull out
the oil filter. Clean oil filter every six
months or 500 hours operation.
ENGINE MAINTENANCE
Do not wash the air cleaner element with
detergent because this is a wet-type
element. Change air cleaner element every
six months or 500 hours operation (or
earlier if dirty).
Periodic checks and maintenance are very
important for keeping the engine in good
condition and durable. The chart on page
18 indicates which checks to make and
when to make them. The mark “•”
indicates that special tools and skills are
required. Items marked “•” should be
serviced by an authorized Yanmar dealer,
unless the owner has the proper tools and
is mechanically proficient.
Consult your Yanmar dealer.
Shut off the engine
before performing
any maintenance. If the engine must be
run, make sure the area is well ventilated. The exhaust contains poisonous
carbon monoxide gas.
After the engine
has been used,
clean the engine immediately with a
cloth to prevent corrosion and to
remove sediment.
CHANGING THE AIR CLEANER ELEMENT
1. Drain the fuel oil from the fuel tank.
CLEANING THE SPARK ARRESTER
If the engine has
been running, the
muffler and the spark arrester will be
very hot. Allow these to cool before
proceeding.
Remove the lock nut, end cap and diffuser
discs and clean off the carbon deposits.
Clean spark arrester every three months or
100 hours operation (or earlier if dirty).
Clamp
Spark
Arrester Diffuser
Discs
See the section for changing the air
cleaner element under Preparations for
starting in the engine owner’s manual.
Never run the
engine without the
air cleaner element or with a defective
element.
Note: A clogged element hinders the flow
of air to the combustion chamber. This
reduces engine output, increases lube oil
and fuel oil consumption and makes
starting difficult. Make sure you clean your
element regularly.
CLEANING AND REPLACING THE FUEL
FILTER
The fuel filter also has to be cleaned
regularly to insure maximum engine

TIGHTEN CYLINDER HEAD BOLTS
Tightening the cylinder head bolts requires
a special tool. Don’t try it yourself. Consult
your Yanmar dealer.
Dayton Operating Instructions and Parts Manual
Models 3ZC06B and 4W315B
(continued)
CHECKING THE INJECTION NOZZLE,
INJECTION PUMP, ETC.
• Adjusting the valve head clearance for
the intake and exhaust valves.
• Lapping of intake and exhaust valves.
• Replacing piston ring.
All these require special tools and skills.
Consult your Yanmar dealer.
Do not perform the
injection nozzle
test near an open fire or any other kind
of fire. The fuel spray may ignite. Do
not expose bare skin to the fuel spray.
The fuel may penetrate the skin and
cause injury to the body. Always keep
your body away from the nozzle.
CHECKING AND REPLENISHING BATTERY FLUID AND CHARGING THE
BATTERY (MODEL 4W315B ONLY)
Battery fluid will be lost through continuous charging and discharging.
The battery
electrolyte contains sulfuric acid. Protect your eyes,
skin, and clothing. In case of contact,
flush thoroughly with water and get
prompt medical attention, especially if
your eyes are affected.
Batteries generate
hydrogen gas,
which can be highly explosive. Do not
smoke or allow flames or sparks near
the battery, especially during charging.
Note: Much more fluid is lost during
summer than in winter.
Before starting, check for physical damage
to the battery and also the electrolyte
levels, and replenish with distilled water up
to the upper mark if necessary. When
actual damage is discovered, replace the
battery. Check battery fluid monthly.
Before charging,
remove the cap
from each cell of the battery. Charge
the battery in a place where there is
plenty of ventilation. Discontinue
charging if the electrolyte temperature
exceeds 45° C (117° F).
Do not charge the
battery with the
battery cable still connected. The
diodes will be damaged by the high
voltage.
Connect the (+)
lead of the charger
to the (+) terminal of the battery, and
the (–) lead to the (–) terminal. Reversed polarity will damage the
charger rectifier or the battery.
Storage
Remove all fuel
from fuel tank
before storing generator. Store fuel in
approved container. Store fuel in a
well-vented area free of open flames
or sparks.
The muffler
becomes very hot
during operation. The muffler remains
hot for a while after shutdown. Let
engine cool before storing.
IMPORTANT: Keep generator level while
in storage. Never store generator upside
down or standing on end.
Cover and store generator in a clean, dry
place. Do not expose generator to extreme
high or low temperatures during storage.

NOTE: The five-year limited warranty below covers all non-engine parts of this generator including the alternator. Yanmar warrants the
engine. See engine owner’s manual for engine warranty information.
LIMITED WARRANTY
Dayton Five-Year Limited Warranty. Professional-duty electric generator alternators, Models 3ZC06B and 4W315B, are warranted
by Dayton Electric Mfg. Co. (Dayton) to the original user against defects in workmanship or materials under normal use for five years
after date of purchase. Any part which is determined by Dayton 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 state to state.
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 illustrate and describe the products in this literature accurately; however,
such illustrations and descriptions 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 states and localities 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, please review the product application, and national and local codes and regulations, and be sure that
the product, installation, and use will comply with them.
Certain aspects of disclaimers are not applicable to consumer products; e.g., (a) some states 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 states 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 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.
