DOUBLE THROW TRANSFER SWITCH
Potential hazards exist when a portable electric generator is
connected to the main electrical supply coming into the house.
It is at that point that the electrical generator could feed back into the utility
company's system causing possible electrocution of workers who are repairing
the electrical lines.
To avoid back feeding of electricity into utility systems, a double-throw transfer
switch must be installed between the generator and utility power. The Double-
Throw Transfer Switch should be installed by a licensed electrician and in com-
pliance with all state and local electrical codes. (When installing a Double-
Throw Transfer Switch, a minimum of 10 gauge wiring must be used.)
The electrician should also install a sub-panel to isolate the circuits you would
want to use during an emergency or electrical power outage. Your generator will
not be large enough to handle the load of all the lights, appliances, TV, etc. at
one time. To select which items to run during the electrical power outage, see
Wattage Calculation section in this manual.
OBTAINING ELECTRICITY FROM THE GENERATOR
There are basically 2 ways to obtain electricity from a generator:
1. Use of extension cords directly from the generator to the appliance, lights,
tools, etc.
2. Use of a double-throw transfer switch installed directly to the main electrical
supply outside of house.

OPERATION
KNOW YOUR GENERATOR
Read this General Manual and Safety Rules before operation of your Generator.
Compare the illustration in your parts manual with your generator to familiarize yourself with
the location of various controls and adjustments. Save all manuals for future references.
GENERATOR CAPACITY
IMPORTANT: Exceeding the rated capacity of your generator can result in serious damage
to your generator and connected electrical devices. See the Wattage Calculation section in
this manual to assist you in determining the appliances and tools that can be run with the
wattage capacity of your generator.
CIRCUIT BREAKERS
Each receptacle has a circuit breaker to protect the generator from overloading. If the circuit
breaker trips, unplug all electrical loads from the generator. Let the circuit breaker cool
down. Push circuit breaker button to reset.
LOW OIL PROTECTION
Your generator engine is equipped with Low Oil Shutdown. Low Oil Shutdown is
a safety device designed to protect your engine from damage in the event the oil
level in the crankcase is low.
If while the engine is running, the oil gets low, it will automatically shut itself
down and will not restart until the oil is added. If the oil is low before start-up,
the generator will not start until oil is added.
NOTE: The Low Oil Shutdown mechanism is very sensitive. You must fill the
engine to the full mark on the dipstick to inactivate this safety device.
FULL POWER
When placed in the 120V position it allows you to receive the full capacity of the
generator by using all 120 volt receptacles. When in the 120/240 position, you
will only be able to receive half the available watts when using the 120 volt re-
ceptacles and the full available watts when using the 240 4-prong twistlock
receptacle.

13- ENG D28512
IDLE CONTROL
Choose the correct application.
1. For normal application such as power tools, small electric appliances, light
bulbs, and radios:
Place the idle control switch in the ON position. The generator
will idle down when there is no load. This lowers the engine
noise, saves on fuel consumption, and engine life.
2. Idling down IS NOT recommend on large motors (refrigerators,
freezers, etc) or voltage sensitive electronic equipment
(computers, televisions, etc). For these applications:
Place the idle control switch in the OFF position.
12V DC OUTLET
IMPORTANT: Allow generator to run at no load for 5 minutes upon each initial
start-up to allow engine to stabilize.
IMPORTANT: When the unit is running the battery will charge. DO NOT
connect the 12V DC cables to the generator’s battery.

4. Disconnect the spark plug wire and remove the spark plug.
5. Add one teaspoon of oil through the spark plug hole.
6. Place rag over spark plug hole and pull the recoil a few times to lubricate
the combustion chamber.
7. Replace the spark plug, but do not connect the spark plug wire.
NOTE: If a fuel stabilizer is not used, all gasoline must be drained from the tank
and carburetor to prevent gum deposits from forming on these parts and causing
possible malfunction of the engine.
GENERATOR
• Clean the generator as outlined in the Maintenance Section on this manual.
• Check that cooling air slots and openings on generator are open and
unobstructed.

WATTAGE CALCULATIONS
Never exceed the rated capacity of your generator. Serious damage to the
generator or appliance could result from an overload.
1. Starting and running wattage requirements should always be calculated
when matching a generators wattage capacity to the appliance or tool.
2. There are two types of electrical appliances that can be powered by
your generator:
A. Items such as radios, light bulbs, television sets, and microwaves
have a "resistive load". Starting wattage and running wattage are
the same.
B. Items such as refrigerators, air compressors, washer, dryer, and
hand tools that use an electrical motor have an "inductive load".
Inductive load appliances and tools require approximately 2 to 4
times the listed wattage for starting the equipment. This initial load
only lasts for a few seconds on start-up but is very important when
figuring your total wattage to be used.
C. Always start your largest electric motor first, and then plug in other
items, one at a time.
NOTE: On 120-volt loads the maximum starting wattage should NOT
exceed one half of the rated generator wattage. Example: a 5000 rated
wattage generator = 2500 maximum starting wattage.
IMPORTANT
DETERMINING WATTAGE REQUIREMENTS
Before operating this generator list all of the appliances and/or tools that are
going to operate at the same time. (Then determine the starting wattage
requirements and the running wattage requirements by following example
and/or refer to household wattage calculator.)
1. First total the running wattage of all appliances and/or tools that will be
operated at the same time.
Running Watts Starting Watts
Example 1:
Lights = 100 Watts 0
Television = 300 Watts 0
Slow Cooker = 250 Watts 0
TOTAL =650 Watts 0
2. Next the starting wattages of any appliances and/or tools that will start and
stop during operation.
Running Watts Starting Watts
Example 2:
Small Refrigerator 500 Watts 2000 Watts
TOTAL =500 Watts 2000 Watts
3. The running wattage of examples 1 & 2 totals 1150 watts. The starting
wattage of the small refrigerator is 2000 watts which is 1500 watts more
than the running watts. Take this difference of 1500 starting watts from the
refrigerator and add to the total running watts of 1150.
Example 3: 1500 Starting Watts
1150 Running Watts
TOTAL =2650 Total Watts
Generator must have a maximum capacity of at least 2650 watts.

STARTING WATTAGE REQUIREMENTS
1. Some appliances and tools will list on the motor nameplate the starting
and running voltage and amperage requirements. Use the following
formula to convert voltage and amperage to wattage:
Volts X Amp = Watts
Example: 120 volts x 10 amps = 1200 watts
2. To determine the approximate starting wattage requirement for most
appliances and tools with inductive type motors, multiply the wattage that
was calculated by 2 to 4 times to assure adequate generator capacity. If
the nameplate information is not available use the values on the following
chart as a guide.
3. Remember that the starting and running wattage for resistive loads are the
same. (Example: a 100 watt light bulb requires only 100 watts to start.)
Most resistive loads will be listed in wattage.
The wattage ratings shown are averages. Wattage requirements may vary
with different brands of appliances.
Application Guide
To select the right generator for your needs, total the wattage
of the items to be run at the same time.
