GENERAL SAFETY PRECAUTIONS
• NEVER use the generator to power medical support
equipment.
• DO NOT operate the generator when you are tired or
under the inuence of drugs, alcohol, or medication.
• DO NOT use generator with electrical cords which are
worn, frayed, bare, or otherwise damaged.
• All electrical tools and appliances operated from this
generator must be properly grounded by use of a third
wire or be double-insulated.
• When this generator is used to supply a building wiring
system the generator must be installed by a qualied
electrician and connected to a transfer switch as a
separately derived system in accordance with NFPA 70,
National Electrical Code.
• If you begin to feel sick, dizzy, or weak while using
the generator, move to fresh air IMMEDIATELY. See a
doctor, as you can have carbon monoxide poisoning.
• Only use OUTSIDE and far away from windows, doors,
and vents as recommended by the US Department
of Health and Human Services Centers for Disease
Control and Prevention. Your specic home and/or wind
conditions may require additional distance.
• While operating and storing, keep at least ve feet
of clearance on all sides of the generator, including
overhead. Allow the generator to cool a minimum of 30
minutes before storage. Heat created by the mufer and
exhaust gases could be hot enough to cause serious
burns and/or ignite combustible objects.
• DO NOT touch the mufer or engine. They are very
HOT and will cause severe burns. DO NOT put body
parts or any ammable or combustible materials in the
direct path of the exhaust.
• ALWAYS remove any tools or other service equipment
used during maintenance away from the generator
before operating.
• Avoid skin contact with engine oil or gasoline. Wear
protective clothing and equipment. Wash all exposed
skin with soap and water.
• A transfer switch must be installed by a licensed
electrician approved by the authority having jurisdiction.
The installation must comply with all applicable laws
and electrical codes.
FUEL SAFETY
• Store fuel in a container approved for gasoline.
• DO NOT smoke when lling the generator with gasoline.
• DO NOT allow the generator’s gas tank to overow
when lling.
• Shut down the engine and allow it to cool for two
minutes before adding gasoline or oil to the generator.
• NEVER remove the fuel cap when the generator is
running. Shut off the engine and allow the unit to cool
at least two minutes. Remove the fuel cap slowly to
release pressure, keep fuel from escaping around the
cap, and to avoid the heat from the mufer igniting fuel
vapors. Tighten the fuel cap securely after refueling.
• Wipe spilled fuel from the unit.
• NEVER attempt to burn off spilled fuel.
• NEVER overll the fuel tank. Leave room for fuel to
expand. Overlling the fuel tank can result in a sudden
overow of gasoline and result in spilled gasoline
coming in contact with HOT surfaces.
• Spilled fuel can ignite. If fuel is spilled on the generator,
wipe up any spills immediately. Dispose of rag properly.
Allow area of spilled fuel to dry before operating the
generator.
• Wear eye protection while refueling.
• NEVER use gasoline as a cleaning agent.
• Store any containers containing gasoline or LPG/
propane in a well-ventilated area, away from any
combustibles or source of ignition.
GASOLINE AND GASOLINE VAPOR (GAS)
DANGER
Fire and explosion hazard. Gasoline and LPG/propane
are highly explosive and ammable and can cause
severe burns or death.
• In case of a gas re, DO NOT attempt to extinguish
the ame if the fuel tank valve is in the ON position.
Introducing an extinguisher to a generator with an open
fuel valve could create an explosion hazard.
• Gas has a distinctive odor, this will help detect potential
leaks quickly.
• Gas vapors can cause a re if ignited.
• Gasoline is a skin irritant and needs to be cleaned up
immediately if it comes in contact with the skin.
When starting the generator:
• Make sure that the fuel cap, air lter, spark plug, fuel
lines, and exhaust system are properly in place.
• If you spill any gasoline on the tank, allow it to fully
evaporate before operating.
• Make sure the generator is on a at surface before
operating.

CO SENSOR
The CO Sensor monitors for the accumulation of
poisonous carbon monoxide gas around the generator
when the engine is running. If increasing levels of CO gas
are detected, the CO Sensor automatically shuts down the
engine.
The CO Sensor will also detect the accumulation of carbon
monoxide from other fuel burning sources used in the area
of operation. For example, if the exhaust of fuel burning
tools is pointed at a CO Sensor-equipped generator, a
shut-off may be initiated due to rising CO levels. This is not
an error. Hazardous carbon monoxide has been detected.
Move and redirect any additional fuel burning sources
to dissipate carbon monoxide away from personnel and
occupied buildings.
Note: Remote start-equipped generators must be restarted
with the START/STOP switch on the control panel
after an automatic shut-down occurs.
Generators are intended to be used outdoors, far from
occupied buildings and the exhaust pointed away from
personnel and buildings. If misused and operated in a
location that results in the accumulation of CO, like in
a partially enclosed area, the CO Sensor shuts off the
engine, noties the user with a RED indicator light, and
directs the user to read the Action Label for steps to take.
The CO Sensor DOES NOT replace carbon monoxide
alarms. Install battery-powered carbon monoxide alarm(s)
in your home.
WARNING
Automatic shutoff accompanied with a ashing RED
light in the CO Sensor portion of the control panel is an
indication that the generator was improperly located. If
you start to feel sick, dizzy, weak, or carbon monoxide
detectors in your home indicate an alarm, get to fresh
air immediately. Call emergency services. You may have
carbon monoxide poisoning.
ACTION LABEL
CONTROL PANEL CO AUTO-SHUTOFF
CO SENSOR INDICATOR LIGHTS
Color Description
RED
Carbon monoxide accumulated around
the generator. After shut-off, the RED
indicator light in the CO Sensor area
of the control panel will ash to provide
notication that the generator was shut-
off due to an accumulating CO hazard.
The RED light will ash for at least ve
minutes after a CO shut-off.
Move the generator to an open, outdoor
area far away from occupied spaces
with exhaust pointed away. Once
relocated to a safe area, the generator
can be restarted. Introduce fresh air and
ventilate the area where the generator
had shut down.
YELLOW
A CO sensor system fault occurred.
When a system fault occurs, the
generator is automatically shut down
and the YELLOW indicator light in the
CO auto-shutoff area of the control panel
will ash to provide notication that the a
fault has occurred. The YELLOW light
will ash for at least ve minutes after a
fault. The generator can be re-started,
but may continue to shutoff. A CO sensor
fault can only be diagnosed and repaired
by an authorized Westinghouse service
center.

fully closed position.
FREQUENCY OF USE
If the generator will be used on an infrequent or intermittent
basis (more than one month before next use), refer to
the Battery Maintenance and Storage sections of this
manual for information regarding battery charging and fuel
deterioration.
AC CIRCUIT BREAKERS
The circuit breakers will automatically switch OFF if there
is a short circuit or a signicant overload of the generator
at each receptacle.
If an AC circuit breaker switches OFF automatically,
check that the appliance is working correctly and it does
not exceed the rated load capacity of the circuit before
resetting the AC circuit breaker ON.
OPERATION

GENERATOR CAPACITY
NOTICE
DO NOT overload the generator’s capacity. Exceeding
the generator’s wattage/amperage capacity can damage
the generator and/or electrical devices connected to it.
Make sure the generator can supply enough continuous
(running) and surge (starting) watts for the items you will
power at the same time.
The total power requirements (Volts x Amps = Watts) of all
appliances connected must be considered. Appliance and
power tool manufacturers usually list rating information
near the model or serial number.
To determine power requirements:
1. Select the items you will power at the same time.
2. Total the continuous (running) watts of these items. This
is the amount of power the generator must produce
to keep the items running. See the wattage reference
chart on the next page.
3. Estimate how many surge (starting) watts you will need.
Surge wattage is the short burst of power needed to
start electric motor-driven tools or appliances such as a
circular saw or refrigerator. Because not all motors start
at the same time, total surge watts can be estimated by
adding only the item(s) with the highest additional surge
watts to the total rated watts from step 2.

POWER MANAGEMENT
To prolong the life of the generator and attached devices,
use care when adding electrical loads to the generator.
There should be nothing connected to the generator
outlets before starting the engine. The correct and safe
way to manage generator power is to sequentially add
loads as follows:
1. With nothing connected to the generator, start the
engine as described in this manual.
2. Plug in and turn on the rst load, preferably the largest
load you have.
3. Permit the generator output to stabilize (engine runs
smoothly and attached device operates properly).
4. Plug in and turn on the next load.
5. Again, permit the generator to stabilize.
6. Repeat steps 4 and 5 for each additional load.

STORAGE
Proper storage preparation is required for trouble-free
operation and generator longevity.
NOTICE
Gasoline stored for as little as 30 days can deteriorate,
causing gum, varnish, and corrosive buildup in fuel lines,
fuel passages, and the engine. This corrosive buildup
restricts the ow of fuel, which can prevent the engine
from starting after a prolonged storage period. The use
of fuel stabilizer signicantly increases the storage life of
gasoline. Full-time use of fuel stabilizer is recommended.
Follow the manufacturer’s instructions for use.
STORAGE TIME RECOMMENDED PROCEDURE
Less than 1 month No service required.
2 to 6 months
Fill with fresh gasoline and add
gasoline stabilizer. Drain the
carburetor oat bowl.
6 months or longer
Drain the fuel tank and carburetor
oat bowl.
SHORT TERM STORAGE
• Allow the generator to cool a minimum of 30 minutes
before storage.
• If operating on LPG, turn the propane tank valve to the
fully closed position and disconnect the LPG/propane
hose from the generator and propane tank.
• Replace all protective covers on the generator control
panel.
• Wipe the generator with a moist cloth. Clean any debris
from the mufer cooling vents.
• Store the generator in a well-ventilated, dry location
away from sparks, open ames, pilot lights, heat, and
other sources of ignition such as areas with a spark-
producing electric motor or where power tools are
