Extension Cords
When using an appliance or tool at a considerable
distance from the generator, a 3-wire extension cord
that has a 3-blade grounding plug and a 3-slot recep-
tacle that accepts the tool's plug MUST be used in
order to reduce the risk of electrical shock. A cord of
adequate size must be used. Using the following chart
to determine the minimum wire size required.
An extension cord that is hot to the touch is
overloaded. Repair or replace damaged exten-
sion 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 Calculation
section in this manual.
ASSEMBLY
Read this manual. Do not attempt to operate
equipment until you have read this Manual for
Safety, Operation, and Maintenance Instruc-
tions.
NOTE: This manual is a general manual. Informa-
tion in this manual may or may not pertain to your

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.

11 — ENG
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 and use of various controls.
Save all manuals for future references.
IMPORTANT: Exceeding the rated capacity of your
generator can result in serious damage to your genera-
tor and connected electrical devices. See the Wattage
Calculation section in this manual to assist you in
determining the appliances and tools that can be ran
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 SHUTDOWN
Your generator engine is equipped with Low Oil Shut-
down. 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 SWITCH
IMPORTANT: Allow generator to run at no load for 5
minutes upon each initial start-up to allow engine to
stabilize.
1. Operate the generator in the 120V/240V mode for
most applications.
2. The 120V mode is needed when starting large 120V
motors. In this mode the maximum surge amps
are available for easier start-up.
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 con-
sumption, 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.
To charge battery:
1. Using the battery cables supplied, connect the red
positive (+) battery cable to the battery's positive
(+) terminal.
2. Attach the other end of the red positive (+) battery
cable to the generators (+) 12V DC outlet.
3. Connect the black negative (-) battery cable to the
battery's negative (-) terminal.
4. Attach the other end of the black negative (-)
battery cable to the generators (-) 12V DC outlet.
5. Charge the battery according to battery or equip-
ment manufacturer recommendations.
To operate 12V DC equipment:
1. Refer to the 12V DC equipment owner's manual for
operation of equipment and any special cable or
adapter requirements.

2. Check fuel level and fill as required. Make sure
generator is turned off and has been allowed time
to cool down. Use clean, fresh, regular unleaded
gasoline with a minimum of 87 octane. Do not mix
oil with gasoline.
Never fill fuel tank completely. Fill tank to 1/2"
below the bottom of the filler neck to provide
space for fuel expansion. Wipe any fuel spillage
from engine and equipment before starting
engine.
BEFORE START UP
This generator has been shipped from the
factory without oil in the crankcase. Operat-
ing the unit without oil can damage the
engine.
Always check engine oil level before every

could result in serious damage to the engine.
Follow the steps listed below before starting
generator:
1. Check engine oil. Refer to the Engine Operator's
Manual for correct grade and quantity of oil.
Never fill fuel tank indoors. Never fill fuel tank
when engine is running or hot. Do not smoke
when filling fuel tank.
Never run engine indoors or in enclosed, poor
ventilated areas, engine exhaust contains
carbon monoxide, an odorless and deadly gas.
3. Make sure generator is grounded in accordance
with local requirements.
4. All electrical loads MUST be disconnected.
5. The idle control MUST be in the OFF position.
Engine speed has been factory set to provide
safe operation. Tampering with the engine
speed adjustment could result in overheating of
attachments and could cause a fire. Never
attempt to “speed-up” the engine to obtain
more performance. Both the output voltage and
frequency will be thrown out of standard by this
practice, endangering attachments and the user.
You MUST unplug any load from the generator
before starting to prevent permanent damage to
any appliances.

should extend. If the RESET button does not
extend, notify a Porter-Cable Authorized Service
Center.
2. To restore power, depress the RESET button firmly
into the GFCI unit until an audible click is heard. If
reset properly, the RESET button is flush with the
surface of the test button. When the button stays
in, the power is ON.

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:
. 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. lways 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
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

17 — ENG
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
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.
WATTAGE CALCULATIONS
The wattage ratings shown are averages. Wattage requirements may vary
with different brands of appliances.

WIRING
ENGINE
Allow the generator to run 5 minutes at no load for the engine and the genhead to
stabilize.
OPERATION 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.
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.
STORAGE 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.
