Caution Statements
Caution: The brass connecting tab on some 120VAC duplex receptacles have been removed. Each
receptacle is powered by a separate generator winding. When replacing a receptacle, inspect
the brass tab that normally links both receptacles. If it is removed, be sure to remove the
brass tab from the replacement receptacle before it is installed. Failure to remove the tab will
cause a direct short to the generator windings and cause possible generator damage.
Caution: Avoid installing the generator set beside heat generating equipment, or directly below water
or steam pipes or in the vicinity of corrosive substances or vapors, metal particles and dust.
Heat can cause engine problems to develop and unwanted substances can cause rust or
generator failure over time.
Caution: Do not apply high voltage to windings in a moisture−saturated condition. Moisture can cause
insulation breakdown, making it necessary to return the generator to the factory for repair,
and consequent expense and loss of time.
Caution: Use only original equipment or authorized replacement parts. Using the correct parts will
assure continued safe operation as designed.
Caution: Do not support the generator from the top of the wrap frame.
Caution: Do not tamper with or change the engine speed. Engine speed is factory set to produce the
correct voltage and output frequency.
Caution: Never operate the engine without a muffler. The engine is designed to have the correct
exhaust components installed and operating without these components can present a fire
hazard, cause excessive exhaust gases and cause damage to engine. Inspect muffler
periodically and replace if necessary.
Caution: Operate the generator only on a level surface. Operation of the generator on an incline or
slope may degrade engine lubrication and result in engine failure.
Caution: Always fill fuel tank with clean fresh fuel before use. Never leave fuel in tank for long storage
periods. Old fuel becomes stale and can damage the fuel system causing the engine not to
start. Always drain the fuel tank after use before storage.
Caution: For electric start models, do not place the key switch in the start position when engine is
running. This causes the starting motor to engage and may damage the starter and engine.
Caution: This generator must have a battery installed for operation. The battery is used during stating

Receiving & Installation
Receiving & Inspection When you receive your generator, there are several things you should do immediately.
1.
2.
3.
Observe the condition of the shipping container and report any damage immediately to
the commercial carrier that delivered your system.
Verify that the part number of the system you received is the same as the part number
listed on your purchase order.
If the system is to be stored for several weeks before use, be sure that it is stored in a
location that conforms to published storage temperature and humidity specifications.
Lifting the Generator
When lift or hoist equipment is used to lift the generator and move it to position, be careful not to
contact overhead wires or other obstacles. The generator weighs between 100 and 350 lbs.
Use proper lift equipment and methods to avoid injury. Lift only by the tubular metal frame.
Figure 3-1 DG Series Generators
If you will not be using the generator set for a significant amount of time (3 months or longer) you
should store the generator to prevent any problems that could arise from sitting idle. Please fully
read the following guidelines prior to storing the unit.
1. Close all the fuel valves.
Note: Do not let the fuel tank run completely empty. Unlike gas engines, diesel engines must be
primed to remove air from the fuel lines.
2. Disconnect and remove the battery if your generator set is so equipped.
3. Drain the used oil from the engine’s crankcase and refill it with clean oil.
4. Provide maintenance to the engine and generator set as described in the engine and
generator maintenance sections of this manual.
5. Cover any bare metal spots with paint or another type of rust preventative.
WARNING: Never store an engine with fuel in its tank indoors or in an enclosed, poorly ventilated area
where diesel fumes could reach an ignition source and cause an explosion.
Storage
MN2414
Receiving & Installation 3-1
Physical Location
The mounting location of the system is important. It should be installed in an area that is
protected from direct harmful gases or liquids, dust, metallic particles, shock and vibration. It can
only be installed in an outdoor location so the exhaust fumes are vented to the atmosphere. This
system must never be installed inside an enclosed building, home, shop or garage etc.
Several other factors should be carefully evaluated when selecting a location for installation:
1. For effective cooling and maintenance, the generator should be mounted on a flat, smooth,
non-flammable level surface. A concrete pad is ideal and provides a secure installation.
2. The location for the generator must be dry. Never operate a generator in an area that
has standing water or puddles.
3. Installation should prevent obstructions by buildup of leaves, grass, sand, snow, etc. It
is important that the unit be operated in a reasonably clean environment.
4
All engines give off considerable heat when running. The engine in your generator set
uses air to keep it cool so it is important that the ambient temperature is cool and does
not exceed 100°F (even while it is running). Where natural ventilation is inadequate a
fan to boost circulation should be used.
5. Exhaust Gases from internal combustion engines are extremely poisonous. Never
operate an engine indoors.
WARNING: Exhaust fumes/gases are extremely dangerous and can cause severe illness or death. Never
breath exhaust fumes produced by a running engine. Only run the engine outdoors where
ventilation is plentiful. Exhaust gases contain carbon monoxide, a colorless, odorless and
extremely dangerous gas that can cause unconsciousness or death. Symptoms of carbon
monoxide poisoning include: dizziness, nausea, headaches, sleepiness, vomiting or
incoherence. If you or anyone else experiences these symptoms, get out into fresh air
immediately. Stop the engine and do not restart the engine until it has been inspected and if
necessary repaired or reinstalled in a well ventilated area.
6. All electrical equipment should be protected from excessive moisture. Failure to do so
will result in deterioration of the insulation and may result in short circuits and a
possible electrocution hazard.
Installation
The generator is completely assembled, tested and adjusted at the factory before it is shipped to
you. External connections required at the time of installation are:
Note: The generator is shipped dry. This means no oil is in the engine crankcase and no battery
is installed. You must refer to the engine manual and obtain the correct type and quantity
of engine motor oil and the correct battery (if equipped for electric start).
1. Electrical Connections.
2. Ground Connection.
After installation, the post installation checks must be performed prior to starting the engine.
After these checks have been performed and the system operation is verified to be good, refer to
Section 6 Maintenance for periodic checks that must be performed at scheduled intervals to
ensure continued operation with minimal problems.
Electrical Connections All load connections are made at the panel using electrical cords with the proper
mating plug for the receptacle being used. More than one receptacle can be used as long as the
total load does not exceed the continuous rating of the generator.
WARNING: Never connect this generator to any buildings electrical system unless a licensed electrician
has installed an approved transfer switch. The National Electrical Code (NEC) requires that
connection of a generator to any electrical circuit normally powered by means of an electric
utility must be connected by means of approved transfer switch equipment so as to isolate
the electrical circuit from the utility distribution system when the generator is operating.
Failure to isolate the electrical circuits by such means may result in injury or death to utility
power workers due to backfeed of electrical energy onto the utility lines.
Use correct size insulated wire to connect the generator to the load. The gauge of the wire will
depend on the distance to the load, the permissible voltage drop at the load, and the current
required by the load. If you are not sure of the gauge wire needed for your application, consult a
competent electrician. Using wire that is too small can result in fire hazard. Also, be sure the
wire has the appropriate ratings for insulation and environment conditions.
The correct mating connector must be used to fit the connectors provided on the operator panel
of your generator. Table 3-1 describes the connector types provided (receptacles) and the load
characteristics to help you choose the correct size wire. Figure 3-2 shows the receptacles.

Frame Ground Connection
WARNING: Be sure the system is properly grounded before applying power. Do not apply AC power
before you ensure that grounds are connected. Electrical shock can cause serious or fatal
injury. NEC requires that the frame and exposed conductive surfaces (metal parts) be
connected to an approved earth ground. Local codes may also require proper grounding of
generator systems.
The NEC requires that the frame and exposed metal surfaces be at local ground reference
potential to avoid electrical shock hazard. A local ground reference may require a driven earth
ground conductor at the generator installation site. Make the ground connection as shown in
Figure 3-3. Use the appropriate size wire (normally 6 AWG) as required by NEC and local
codes. The local reference ground is normally a copper clad earth ground rod driven into the
earth at least 8 feet.

to bring the oil level to full.
Caution:
This generator must have a battery installed for operation. The battery is used during stating
and during operation. If engine operation is attempted while the battery is removed, damage
to the engine’s electrical components may result.
Battery Connections The generator is shipped with no battery installed.
WARNING: Do not dispose of battery or batteries in a fire. The battery is capable of exploding. If the
battery explodes, electrolyte solution will be released in all directions. Battery electrolyte
solution is caustic and can cause severe burns and blindness. If electrolyte contacts skin or
eyes, immediately flush the area with water and seek medical attention quickly.
WARNING: Do not mutilate the battery . The battery contains electrolyte solution which is caustic and
can cause severe burns and blindness. If electrolyte contacts skin or eyes, immediately flush
the area with water and seek medical attention quickly.
WARNING: A battery presents a risk of electrical shock hazard and high short circuit current. The
following precautions are to be followed when working on batteries:
1. Remove watches, rings, necklaces and all other metal objects.
2. Use tools with insulated handles.
3. Wear rubber gloves and boots.
WARNING: The battery electrolyte is a dilute sulfuric acid that is harmful to the skin and eyes. It is
electrically conductive and corrosive. The following precautions are to be followed when
working on batteries:
1. Wear full eye protection (safety glasses or goggles) and protective clothing.
2. Where electrolyte contacts the skin, flush the area immediately with water and wash it
off using soap and water.
3. Where electrolyte contacts the eyes, immediately flush the eye thoroughly with water
and seek medical attention quickly.
4. Spilled electrolyte is to be washed down with an acid neutralizing agent. A common
practice is to use a solution of one pound (500 grams) bicarbonate of soda to one
gallon (four liters) of water. the bicarbonate solution is to be added until evidence of
reaction (foaming) has ceased. The resulting liquid is to be flushed with water and the
area dried.
WARNING: A battery presents a risk of fire because they generate hydrogen gas. Hydrogen gas is
extremely explosive. Never jump start a battery, smoke in the area around the battery or
cause any spark to occur in the area around the battery. The following precautions are to be
followed when working on batteries:
1. Do not smoke when near batteries.

Use of Electric Motor Loads
Electric motors require much more current (amperes) to start them than to keep them running.
Some motors, particularly split−phase motors are very difficult to start and require 5 to 7 times
more current to start them. Repulsion−induction type motors are the easiest to start and normally
only require 2 to 3 times as much current to start them.
Most fractional horsepower motors take about the same amount of current to start them and
keep them running. This is true whether they are the repulsion−induction type motor, capacitor
type motor, or the split−phase type motor.
Other factors that influence the amount of current needed to start a motor are:
1. The type of load connected to the motor. If the electric motor is connected to a hard
starting load such as an air compressor it will require more starting current. If the same
electric motor is connected to a light load such as a heater or power saw it will require
less starting current.
2. The brand or design of the electric motor. The expected starting current for a
particular size motor will vary depending on the brand of the electric motor as well as
the type of electric motor (Split Phase, capacitor, Repulsion−induction type, etc.)
3. The condition of the electric motor. A clean motor with free turning bearings will
require less starting currents than a similar type motor that is dirty and the bearings are
not as free turning as they used to be.

Troubleshooting and Maintenance
Maintenance
This manual contains only very minimal engine maintenance instructions. Refer to the engine
manufacturer’s owner’s manual for specific engine maintenance instructions for your generator
set. Any maintenance instructions or recommendations in the engine owner’s manual take
precedence over any of the following general recommendations.
General:
1. Inspect the fuel system for leaks. Replace all defective components immediately.
2. Inspect and replace any fuel line that shows signs of deterioration.
3. Inspect all fuel clamps to ensure they are tight.
4. Make sure the fuel cap fits snugly on the fuel tank and that the fuel tank does not leak.
5. Inspect and clean the battery posts and the associated battery cable terminals.
6. Inspect the external wire cables and connectors used with the generator set for cuts,
frayed insulation, or loose connections. Repair or replace damaged parts before use.
7. The engine should be checked for proper speed setting(s).
Prior to adjusting the engine speed, turn the auto idler switch to “OFF” (if present).
Make sure that the auto idler magnet does not touch the throttle lever of the engine
when running.
a. Disconnect all electrical loads and start the engine.
b. Adjust the engine speed to 3720 RPM (62 Hz) with no load speed.
c. Adjust the auto idler speed after you have accomplished the above adjustment.
d. Adjust the auto idler speed by moving the electro−magnet back and forth in the
magnet bracket to achieve an engine RPM of 2500−2900 with the auto idler switch
“ON”.
8. Test all GFCI receptacles monthly by pressing the test button on the receptacle and
making sure that the GFCI trips and and no voltage is present at the receptacle.
Replace any GFCI receptacle that fails the test.
Engine:
1. Clean and/or replace any fuel, oil, and/or air filters per the engine manufacturers’
guidelines.
2. Check oil level regularly; at least every 5 to 8 operating hours. Maintain the proper oil
level.
3. Change the oil as is recommended in the engine manufacturer’s owner’s manual.
4. Clean the cooling fins on the engine to keep the engine’s heat dissipation potential at
it’s maximum.
5. Inspect and clean all governor linkages so they operate properly.
Alternator: ( also called Generator End)
This generator set must be run at its proper speed to obtain the correct electrical power at its
output. All engines have a tendency to slow down when a load is applied to it. The engine
governor is designed to hold the operating speed as nearly constant as possible. When the
electrical load is increased, the engine is more heavily loaded and engine speed drops slightly.
This slight decrease in engine speed results in a slight decrease in generator voltage and
frequency output. This voltage and frequency variation has no appreciable effect in the operation
of motors, lights, and most appliances and tools. However, timing devices and clocks will not
keep perfect time when used on this generator.
1. Clean the generator set and remove any and all dust, dirt, or other foreign material.
2. Inspect and clean the cooling air intake and exhaust louvers of the generator end.
Make sure they are clean. Remove dirt or any buildup that may restrict the cooling air
flow.
3. Clean the generator set and its components with a damp cloth or sponge.
Never use a water hose or pressure washer as this may damage electrical
components.
4. Inspect and replace any control panel components that are broken or not working
properly (receptacles, circuit breakers, switches, etc.)
