extension cord should not be used for long distances.
An extension cord that is hot to the touch is
overloaded. Repair or replace damaged extension cords immediately.
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 compliance 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 Calcu-
lation section in this manual.
1. Use of extension cords directly from the generator to
the appliance, lights, tools, etc.

STORAGE
If you are going to store your generator for more than 30
days, use the following information as a guide to prepare
the generator for storage.
Never store generator with fuel in the tank indoors
or in enclosed, poorly ventilated areas, where
fumes can reach an open flame, spark or pilot light
as on a furnace, water heater, clothes dryer or
other gas appliances.
Engine Preparation
1. Add fuel stabilizer to fuel tank to minimize the
formation of fuel gum deposits during storage.
2. Run engine at least 10 minutes after adding stabilizer to allow it to enter the fuel system.
3. Next shut off engine.
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.
Battery (Electric Start Units Only)
• Store battery as described by the battery manufacturer.
NOTE: After storing battery for a long period of time it
may lose it's charge. If the battery loses it's charge,
manually start the engine with the battery connected.
The engine will recharge the battery as it runs.

WATTAGE CALCULATIONS
IMPORTANT
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.
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
wattage calculator on page 16.)
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.

WATTAGE CALCULATIONS
STARTING WATTAGE REQUIREMENTS
1. Some appliances and tools will list on the motor name
plate the starting and running voltage and amperage
requirements. Use the following formula to convert
voltage and amperage to wattage:
Volts X Amp = Watts
Example 1: (Starting voltage and amperage for 1/3
HP furnace fan)
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. (Refer to page 11 for
wattage calculations.)

ENGINE
Use clean, fresh gasoline with a minimum 87 octane rating. Do not add gasoline during or
immediately after use.
Refer to engine owner’s manual for oil recommendations.
Most generators are equipped with a low-oil shutdown. If the oil is low or if the Generator
is not level, the engine will not start.
Make wattage calculations before use. Refer to general operator’s manual for further
instructions.
Contact an electrician for any wiring instructions. If wiring into a house, a double-throw
transfer switch and a heavy duty cord set must be used.
Use a standard (12V) lawn and garden battery with a minimum of 45 A.H. or 210 CCA.
The voltage and frequency are regulated by the rpm’s of the engine. Do not adjust the
throttle or governor to achieve higher performance. This will only alter the factory Pre-set
settings and damage anything connected to the generator.
Be sure a volt/amp surge protector is used when sensitive electronic equipment is used,
such as: televisions, computers, stereos, and etc… The damage of such equipment
without the use of a protector WILL NOT be covered under warranty.
Do not adjust or attempt maintenance without consulting engine manual or an authorized
engine service center.
Add stabilizer to fuel tank and run engine for 5 minutes before storage.
STORAGE
OPERATION
When in long term storage, operate the generator every 60 days for at least 10 minutes
with a load on it. This will prevent the loss of residual magnetism that produces the
electricity.
Allow the generator to run 5 minutes at no load for the engine and the genhead to
stabilize.
Make sure the adequate size of extension cord is used. Refer to the Grounding
Instructions/Extension Cord section of the owners manual.
If the generator is operating equipment that is drawing half of the rated watts it is
considered 50% load. Using all of the rated watts is considered 100% load.
