The generator cannot power your entire home -- you must work with the
installing electrician to determine which devices/appliances you wish to
power during an outage. The electrician can help you determine which
circuits and devices can be powered simultaneously without overloading the
generator.
Using as a
Portable Power
Source
When using the generator as a portable power source, you can plug
electric devices and appliances directly into the generator’s electrical
outlets.
There are two different kinds of electrical outlets on the generator:
1. Two 120 Volt, 20 Amp duplex straight-blade receptacles (NEMA 5-
20R duplex receptacles compatible with NEMA 5-20P or 5-15P
mating plugs).
2. One 120/240 Volt, 20 Amp Locking receptacle (NEMA L14-20R)
compatible with NEMA L14-20P mating plugs).
(See more technical detail about these receptacles and their associated
circuit breakers in the “Machine Component Identification” section of this
manual.)
Make sure you plug each electrical device/appliance into the correct
generator outlet based on the device’s plug configuration and
voltage/amperage rating. Never exceed the amperage rating of an outlet.

4. Select a Suitable Site
Before using the generator, you must select a suitable OUTDOOR location for installation and
operation. This location should meet all of the criteria listed below.
WARNING:
You must choose a suitable site for operating your generator to avoid equipment damage
and/or injury and possible death from carbon monoxide poisoning, electric shock, or fire.
Choose a site that meets all of the criteria specified.
Dry, level
surface
The generator should be positioned on a dry, firm, level surface.
Ensure that the generator sits level and will not slide or shift during operation.
If applicable, block the generator’s wheels to prevent sliding and shifting.
Outdoors only –
dangerous
carbon
monoxide
exhaust
WARNING: Carbon monoxide poisoning hazard
The exhaust from your generator contains carbon monoxide (CO), a
poisonous gas that can kill. You cannot smell it, see it, or taste it.
Carbon monoxide exhaust is given off whether you are using gasoline,
natural gas, or propane as the fuel source to power the generator.
Follow the directions below for choosing a location to operate your
generator in order to avoid carbon monoxide poisoning.
The location you choose to operate the generator must be OUTDOORS
and away from all air intakes:
Never run the generator inside any closed or semi-enclosed spaces (even if
outdoors), including homes, garages, basements, sheds, or boxes. These
spaces can trap poisonous gases, even if you run a fan or open windows.
Place the generator so that the exhaust fumes will not be directed towards
people or building air intakes.
Ensure that working, battery-operated or battery back-up carbon monoxide
alarms are used in any dwelling/structure that is in close proximity to the
running generator.
Note that this generator is NOT designed or approved for use in vehicles or
marine applications. Never run the generator inside RVs or other vehicles,
on boats, or on pick-up truck beds.
WARNING:
Never attempt to attach ductwork to the muffler system to allow for
installation inside an enclosure. This could cause hot air deflection,
heat build-up, and increased exhaust back-pressure, resulting in
possible exhaust leakage or damage to the generator.
Adequate
cooling
ventilation
The generator needs adequate, unobstructed flow of air to allow for
proper cooling of engine and generator head.
WARNING:
Heat build-up from inadequate ventilation can result in fire, posing a
serious risk to nearby persons and structures.
Situate so there is adequate clearance around generator to allow for cooling
airflow so that heat does not build up.

Installation/Initial Set-Up
9
Never place the generator immediately adjacent to a building or other
structure –allow at least 7 feet clearance.
Do not run the generator in close proximity to other heat-generating
equipment, such as another generator. The combined heat that is generated
may raise air temperature in the immediate area and there will not be
adequate cooling ventilation.
Do not allow debris to accumulate and block airflow.
Do not operate with a tarp, blanket, or cover surrounding the generator.
No wet
conditions
Choose a location where the generator will NOT be exposed to rain, snow,
or direct sunlight. Exposure to water can cause electric shock.
You may operate the generator under an outdoor, canopy-like structure of
heat-resistant material that is open on all sides. Make sure that all parts of
canopy are at least 7 feet from exhaust, and allow for adequate clearance
above generator so that heat does not build up.
Hot exhaust
clearance
The exhaust gas from your generator is extremely hot and can cause
combustible materials to catch on fire.
Make sure your generator’s exhaust system is at least 7 feet from all
combustible materials and buildings/structures.
Equip the engine with a spark arrestor if the generator will be used near any
ignitable forest, brush, or grassy land. (See the “Specifications” section of
this manual to determine if your generator is already equipped.) Make sure
you comply with applicable local, state, and federal codes.
Keep a fire extinguisher rated “ABC” nearby. Keep it properly charged and
be familiar with its use.
Away from
dust/dirt
Do not use the generator in extremely dusty or dirty conditions. Excessive
dust and dirt can cause premature failure of the machine.
Hearing
protection
Generators can produce noise levels of up to 95 dB in close proximity,
which can be dangerous to human hearing with prolonged exposure.
Hearing protection may be required for persons working within 15-20 feet of
the running generator for an extended period of time.
WARNING:
Never attempt to attach ductwork to the muffler system to lower noise
levels. This could cause hot air deflection, heat build-up, and increased
exhaust back-pressure, resulting in possible exhaust leakage or damage
to the generator.

5. Grounding the generator
Always ensure the generator is properly grounded to prevent electrical shock.
You must always ground the generator by the following method when using the generator as a
portable electrical source:
1) Drive a ¾” or 1” copper pipe or rod into the ground close to the generator. The pipe/rod
must penetrate moist earth –the depth required will be dictated by local soil conditions.
Consult with an electrician.
2) Connect an approved ground clamp to the pipe.
3) Run a 10 gauge wire from the clamp to the generator grounding post located on the rear of
the generator head.
4) Do not connect the generator grounding post to a water pipe or a ground used by a radio
system.
If a licensed electrician installs the generator with a connection to your building’s electrical circuit
for use as a back-up power system, grounding may alternatively be completed through the
building’s grounding system. Ask your electrician. If the generator is not grounded through your
building’s electrical system, follow the procedure above.
WARNING:
Operating the generator when it is not properly grounded can result in electrical shock.

Adjusting / repairing. Always turn off generator and remove spark plug(s) or spark plug wire(s) before
working on the generator to prevent accidental starting. Always discharge the capacitor before working
on the generator head to prevent electrical shock. (See Maintenance & Repair section of this manual for
instructions on how to do this.)
Carbon monoxide poisoning. The running engine gives off carbon monoxide, a poisonous gas that can
kill you. You CANNOT smell it, see it, or taste it. Follow all instructions for site selection and
positioning the generator, and avoid inhaling the exhaust. If you start to feel sick, dizzy, or weak while
using the generator, shut off the engine and get to fresh air RIGHT AWAY. See a doctor. You may have
carbon monoxide poisoning.
Other exhaust dangers. This product contains or emits chemicals known to the State of California to
cause cancer, birth defects or other reproductive harm. Avoid inhalation of exhaust.
Wet conditions. Do not operate the generator or handle any electrical equipment while standing in water,
while barefoot, while hands are wet or while in the rain or snow. Electric shock may result.
Ground fault circuit interrupter. Always use a ground fault circuit interrupter (GFCI) protected
extension cord (or outlet, if generator is equipped) in damp or highly electrical conductive areas and on
construction jobsites to prevent electrical shock.
Avoid contact. Avoid contact with bare wires, terminals, connections, etc. while the unit is running.
Electric shock accident. If an electric shock accident occurs, immediately shut down the source of
electrical power. If this is not possible, attempt to free the victim from the live conductor. Avoid direct
contact with victim. Use a nonconducting implement, such as a dry rope or board, to free the victim from
the live conductor. Apply first aid and get immediate medical help.
Smoking/sparks. Never smoke near the running generator, and never operate near sources of sparks or
flames.
Hot muffler. Never touch hot muffler, hot exhaust manifold, or engine cooling fins. Exhaust and engine
parts can be very hot and will burn you.

3. Starting the Engine
After you have completed the pre-start checklist procedures, you are ready to start the engine.
To start the engine:
1) Disconnect all loads to the generator.
2) Turn the gasoline line valve to the ON position.
3) For cold engine, move choke lever to full choke position. To restart a warm engine, move choke
lever to half choke or to RUN position.
4) Start the engine:
a) Using electric start –
i) Turn the engine key switch to the START position and hold it there until the engine starts.
NOTE: If the engine fails to start after 5 seconds, release key and wait 10 seconds
before attempting to start again. Cranking the electric starter for more than 5
seconds continuously can overheat and damage the starter motor.
ii) Release the key when the engine starts.
b) Using recoil start –
i) Turn the engine key switch to the ON position.
ii) Pull the starter grip lightly until you feel resistance, then pull the starter cord out briskly
and rapidly.
iii) Allow starter cord to return slowly.
5) When engine starts, move choke lever to RUN position.

4. Checking Generator Output
Although the speed of the engine was carefully adjusted at the factory so that the generator
produces the proper voltage and frequency, output voltage should be checked periodically to
ensure the generator is working properly before connecting loads to the generator.
WARNING:
The generator must be run at the correct speed in order to produce the
proper electrical voltage and frequency. Failure to do so could result in
damage to equipment powered by the generator and possible injury to the
individual.
Output voltage should be checked with a portable voltage meter:
1. Start engine and allow to warm up for five minutes. Do not connect any loads.
2. Use voltage meter to check output voltage
at the generator’s outlets/receptacles.
3. Measured voltage should be within the
following ranges:
a. 120V +/- 10% at 120V receptacles.
b. 240V +/- 10% at 240V receptacles.
4. If measured voltage is not within the specified range, have generator adjusted by factory
authorized personnel. Do not attempt to adjust the engine speed yourself.
NOTE:
Slight variation in
voltage/speed with
changing electrical
loads
All engines have a tendency to slow down when a load is applied. When
electrical loads are connected to the generator, the engine is more heavily
loaded and as a result the speed drops slightly.
This slight decrease in speed, together with the voltage drop within the
generator itself, results in a slightly lower voltage when the generator is
loaded to its full capacity than when it is running with no load.
Additionally, there may be small brief surges and drops in voltage as motors
connected to the generator cycle on or off.
The slight variation has no appreciable effect in the operation of motors,
lights, and most appliances.
