FUEL SAFETY
DANGER
Gasoline and liquid petroleum gas
(LPG) are highly explosive and
flammable. Explosions and fire can
cause severe burns or death.
Gasoline and gasoline vapor (Gas)
•Gasoline is highly flammable and explosive.
•Gas expands and contracts with different
temperatures.
•In case of a gas fire, do not attempt to extinguish the
flame if the fuel shutoff 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 fire if ignited.
•Gasoline is a skin irritant and needs to be cleaned up
immediately if it comes in contact with the skin.
Liquid Petroleum Gas (Propane/LPG)
•LPG/Propane is highly flammable and explosive.
•Flammable gas under pressure can cause a fire or
explosion if ignited.
•LPG/Propane can settle in low places because it is
heavier than air.
•LPG/Propane has a distinctive odor added to help
detect potential leaks.
•Always keep LPG/Propane tank in an upright position.
•When exchanging LPG/Propane tanks, be sure the
tank value is the same type.
•In case of a LPG/Propane fire, do not attempt to
extinguish unless the fuel supply can be shut off.
•LPG/Propane will burn the skin. Prevent skin contact
at all times.
WARNING
Never use a gas container, LPG
connector hose, LPG tank or any
other fuel item that appears to be
damaged.

•Make sure that the gas cap, air filter, 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 and propane tank are on a
flat surface before operating.
•If there is a propane odor do not start the unit because
there may be a potential leak.
•Never place propane tank near engine exhaust.
When transporting or servicing the generator:
•Make certain the fuel shutoff valve is off and the fuel
tank is empty.
•Make sure the LPG tank and LPG hose is not attached
to the generator.
•Disconnect the spark plug wire.
When storing the generator:
•Store away from sparks, open flames, pilot lights, heat
and other sources of ignition.
•Do not store gas or LPG tank near furnaces, water
heaters or any other appliances that produce heat or
have automatic ignitions.
CAUTION
Only use approved LPG tanks with
OPD (overfilling prevention device)
valve. Always keep the tank in a
vertical position with the valve on
top and installed at ground level on a
flat surface. Do not allow tanks to be
around any heat source and make sure
it is not exposed to the sun, rain and
dust. When transporting and storing,
turn off the tank valve and fuel valve,
and disconnect the tank. Make sure to
always cover the generator and tank
outlet with protective plastic caps.
CAUTION
Do not allow children to tamper or
play with the propane tank or hose

OPERATION
BEFORE STARTING THE GENERATOR
BEFORE STARTING THE GENERATOR,
REVIEW SAFETY SECTION STARTING
ON PAGE 5.
Location Selection – Before starting the generator,
avoid exhaust and location hazards by verifying:
• You have selected a location to operate the generator
that is outdoors and well ventilated.
• You have selected a location with a level and solid
surface on which to place the generator.
• You have selected a location that is at least 6 feet
(1.8 m) away from any building, other equipment or
combustible material.
• If the generator is located close to a building, make
sure it is not located near any windows, doors and/
or vents.
Weather – Never operate your generator outdoors during
rain, snow or any combination of weather conditions that
could lead to moisture collecting on, in or around the
generator.
Dry Surface – Always operate the generator on a dry
surface free of any moisture.
No Connected Loads – Make sure the generator has no
connected loads before starting it. To ensure there are no
connected loads, unplug any electrical extension cords
that are plugged into the control panel receptacles.
NOTICE
Starting the generator with loads already applied to it could result
in damage to any appliance being powered off the generator during
the brief start-up period.
Grounding the Generator – The National Electric Code
(NEC), as well as many local electrical codes, may require
the generator to be connected to earth ground. The
most common application that requires a ground rod is
when you are using the generator as a separately derived
system to provide back up power to your house. Typically
this is when a transfer switch has a switched neutral.
As the generator application has many variables that
cannot be determined by the manufacturer of the
generator, a licensed electrician will need to determine if a
grounding rod is needed.
WARNING
Always operate the generator on a level surface.
Placing the generator on non level surfaces can
cause the generator to tip over, causing fuel and
oil to spill. Spilled fuel can ignite if it comes in
contact with an ignition source such as a very hot
surface.
Do not operate a device plugged into the USB
ports. Prolonged exposure to engine exhaust can
cause serious injury or death. While charging a
device do not place on the exhaust side of the
generator. Extreme heat caused by exhaust can
damage the device, and cause a potential fire
hazard.
NOTICE
Only operate the generator on a solid, level surface. Operating the
generator on a surface with loose material such as sand or grass
clippings can cause debris to be ingested by the generator that
could:
• Block cooling vents
• Block air intake system

If a licensed electrician has determined the application
requires a ground rod, make sure it is connected to earth
ground by connecting the ground terminal on the control
panel to earth ground using copper wire (minimum 10
AWG). Consult a qualified electrician for local grounding
requirements.
Neutral Bonded: There is a permanent conduct between
the generator (stator winding) and the frame.
WARNING
Be sure the generator is properly connected to
earth ground before operating. The generator
must be grounded to prevent electrical shock
due to faulty appliances.
High Altitude Operation
Engine power is reduced the higher you operate above
sea level. Output will be reduced approximately 3.5%
for every 1000ft of increased altitude from sea level.
This is a natural occurrence and cannot be adjusted by
engine. Increased exhaust emissions can also result
due to increased fuel mixture. Other issues include hard
starting, increased fuel consumption and spark plug
fouling. Contact our service team 1-855-944-3571 for
altitude part kits.

Using Extension Cords
Westinghouse Portable Power assumes no responsibility for the content within this table. The use of this table is the
responsibility of the user only. This table is intended for reference only. The results produced by using this table are
not guaranteed to be correct or applicable in all situations as the type and construction of cords are highly variable.
Always check with local regulations and a licensed electrician prior to installing or connecting an electrical appliance
Using Westinghouse Power Cord
Use the extension cord chart to determine the size
of the conductor for extension cord applications.
Determine the distance of the generator to the
appliance on the top line of the chart. Then select the
rated amperage of the generator on the left side of the
chart. Where the two meet is the size of the conductor
required for the application.
The WCG25 power cord is connected to the generator
at the 120/240 plug. The opposite end of the power
cord is a fan tail receptacle with 2 green receptacles
and 2 red receptacles. Each receptacle is rated at
120 volts AC. To balance the load on the generator’s
alternator, use the red and green identifiers on the fan
tail receptacle. To keep the load balanced, connect
the loads so that both color receptacles are used. An
example is one in red and one in green. Do not connect
2 in red and none in green, or 2 in green and none in
red. If only one color receptacle is used with multiple
loads, the alternator may experience an unbalanced
load, causing undue vibration to generator.

OPERATION
TRANSFER SWITCH CONNECTIONS
The Westinghouse generator is wired with the neutral
bonded to ground. If you are connecting your generator
to a panel board transfer switch, a licensed electrician
will need to consider removing the bonded neutral to
ensure proper operation of household GFCI circuits.
This is done by removing the jumper wire that connects
the alternator ground to the alternator neutral.
If the bonded neutral is removed the generator must be
relabeled as floating neutral on the control panel.
If your generator is equipped with GFCI receptacles,
removing the bonded neutral may not allow proper
operation of the GFCI receptacles. Keep the jumper
wire with the owner’s manual in case it is needed for
future use when not connected to a transfer switch.
Before starting the generator, always check:
• Level of Engine oil
• Level of gasoline in the fuel tank
• Secured connection to an undamaged LPG tank
It is not safe to add gasoline to the fuel tank or engine
oil to the engine while the engine is running or the
engine and muffler are hot.
CHECKING AND / OR ADDING ENGINE OIL
WARNING
Internal pressure can build in the engine
crankcase while the engine is running.
Removing the oil fill plug/ dipstick while the
engine is hot can cause extremely hot oil to
spray out of the crankcase and can severely
burn skin. Allow engine oil to cool for several
minutes before removing the oil fill plug/
dipstick.
The unit as shipped does not contain oil in the engine.
You must add engine oil before starting the generator
for the first time. See Checking Engine Oil and Adding
Engine Oil on page 24 for instructions on checking
engine oil level and the procedure for adding engine oil.
NOTICE
The engine does not contain engine oil as shipped.
Attempting to start the engine can damage engine components.
The owner of the generator is responsible to ensure the proper oil
level is maintained during the operation of the generator. Failure to
maintain the proper oil level can result in engine damage.

sure all engine air inlet and outlet ports are clean of any
dirt and debris to ensure the engine does not run hot.
Clean All Engine Cooling Fins – Use a damp rag and
a brush to loosen and remove all dirt on or around the
engine’s cooling fins.
WARNING
Never store a generator with fuel in the tank
indoors or in a poorly ventilated area where the
fumes can come in contact with an ignition source
such as a: 1) pilot light of a stove, water heater,
clothes dryer or any other gas appliance; or 2)
spark from an electric appliance.
NOTICE
Gasoline stored for as little as 60 days can go bad, causing gum,
varnish and corrosive buildup in fuel lines, fuel passages and the
engine. This corrosive buildup restricts the flow of fuel, preventing
an engine from starting after a prolonged storage period.
Proper care should be taken to prepare the generator for
any storage.
1. Make sure the Engine Switch is switched to STOP
so the generator does not draw power from battery.
2. Clean the generator as outlined in Cleaning the
Generator.
3. Drain all gasoline from the fuel tank as best as
possible.
4. With the fuel shut off valve open, start the engine
and allow the generator to run until all the remaining
gasoline in the fuel lines and carburetor is consumed
and the engine shuts off. If you used propane the
last time you ran the generator: start the unit up
with propane then shut off the propane tank valve
allowing the engine to use up all the remanding
propane in the carburetor before it shuts off.
5. Close the fuel shut off valve.
6. Change the oil (see Changing Engine Oil on page
25).
7. Remove the spark plug (see Spark Plug Maintenance
on page 26) and place about 1 tablespoon of oil in
the spark plug opening. While placing a clean rag
over the spark plug opening, slowly pull there coil
handle to allow the engine to turn over several times.
This will distribute the oil and protect the cylinder
wall from corroding during storage.
8. Replace the spark plug (see Spark Plug Maintenance
on page 26).

9. Move the generator to a clean, dry place for storage.
TROUBLESHOOTING
WARNING
Before attempting to service or troubleshoot the generator, the owner or service technician must first read the owner’s
manual and understand and follow all safety instructions. Failure to follow all instructions may result in conditions that
can lead to voiding of the EPA certification or product warranty, serious personal injury, property damage or even death.

authorized service dealer.
1. Fuel shutoff valve is in the OFF position.
1. Move the fuel shut off valve to the ON
position (see Figure 9 page 21).
2. Generator is out of gasoline.
2. Add gasoline to the generator (see page
19).
3. Fuel flow is obstructed.
3. Inspect and clean fuel delivery passages.
4. Starting battery may have insufficient charge 4. On electric start models only. Check battery
output and charge battery as necessary.
Engine will not start or
remain running while
trying to start.
Generator suddenly
stops running.
5. Dirty air filter
5. Check and clean the air filter (see page 25).
6. Low oil level shut down switch is preventing
the unit from starting.
6. Check oil level and add oil if necessary (see
page 24).
7. Spark plug boot is not fully engaged with
the spark plug tip.
7. Firmly push down on the spark plug boot to

TROUBLESHOOTING
PROBLEM
POTENTIAL CAUSE
SOLUTION
1. Dirty air filter
1. Clean the air filter (see pages 25-26).
Engine runs
erratic; does not hold a
steady RPM.
2. Applied loads maybe cycling on and off
2. As applied loads cycle, changes in engine
speed may occur; this is a normal condition.
3. If trying 1-3 above does not solve
the problem, the cause might be a
fault in the generator
3. Take the generator to your nearest
authorized service dealer.
Push button start is not
working and the cranking
speed drops after each
attempt.
1. Battery is not adequately charged
1. Turn the engine switch to “Run” and hook
up the battery charger (provided) for 1 hour.
Frost on the propane tank or
regulator
2. Try manually starting the generator to let the
battery charge while it is operating.
1. This can be a normal occurrence caused
when liquid propane changes phase to a
gas. As this process occurs the fuel tank
or regulator will cool and allow humid air
surrounding the propane tank or regulator to
condense into frost.
1. As this can be normal, providing all
the propane fuel handling equipment is
functioning normally, no remedy is needed.
2. The propane tank is not equipped with a
OPD (rollover protection device) and has been
stored in a horizontal position allowing liquid
propane to enter the downstream fuel handling
equipment.
2. If you suspect your propane fuel tank is
not equipped with a OPD device, discontinue
operation immediately and replace the
propane fuel tank with a propane tank
equipped with a roll over protection device.
3. Propane fuel tank over filled.
3. If you suspect your propane fuel tank
has been overfilled, discontinue operation
immediately and return the propane fuel tank
to the place of purchase or refilling.
1. Fuel regulator or fuel hose and fittings not
securely sealed.
1. Using a soap solution check each
connection and tighten as needed.
2. Propane fuel regulator vent active.
2. The propane fuel regulator is equipped with
a small vent that will allow a small amount
of propane fuel vapor to escape from the
regulator when the propane tank valve is
opened. This can be normal providing the
venting of the propane is brief. If you suspect
that this is abnormal, immediately discontinue
use and have the propane regulator inspected
by a qualified technician.
3. Residual fuel from the carburetor dispersing
after operation.
3. Normal, no remedy is needed.
1. Propane fuel line kinked or crushed.
1. Inspect propane fuel line and remove kinks
or other obstructions.
2. Fuel selector valve not properly positioned.
2. Rotate the fuel valve fully until the pointer is
directly in line with the desired fuel.
3. Gasoline not purged from the carburetor
before switching to propane.
3. Turn the propane fuel tank valve to closed.
Move the fuel selector valve to propane. Turn
the gasoline fuel valve to off. Start the engine
and allow the engine to run until the fuel has
been consumed in the carburetor. Begin
propane start up procedure.
