• Make certain the fuel shuto valve is o 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 ames, 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
(overlling prevention device) valve. Always
keep the tank in a vertical position with the
valve on top and installed at ground level
on a at 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 o the tank
valve and fuel valve, and disconnect the tank.
Make sure to always cover the generator and
tank outlet with protective plastic caps.
Large (500-1000 gallon) LPG tanks will
require a certied plumber to install the fuel
line to the generator and the loose regulator
is not used (the regulator that is attached to
the fuel tank). The pressure as measured at
the regulator mounted to the generator must
be 7” to 14” of water column. The plumber
will ensure that the pressure is correct or
install a step down regulator if needed.
CAUTION
Do not allow children to tamper or play with
the propane tank or hose connections.
WARNING
If there is a strong smell of propane while
operating the generator close the valve on
the propane tank immediately. Once the
propane is o, use soapy water to check for
leaks on the hose and connections on the
tank valve and the generator. Do not smoke
or light a cigarette or check for leaks using
any open ame source such as a match or
lighter. If a leak is found contact a qualied
technician to inspect and repair the LPG
system before using the generator.
DANGER
Gasoline and liquid petroleum gas
(LPG) are highly explosive and
ammable. Explosions and re can
cause severe burns or death.
Gasoline and gasoline vapor (Gas)
• Gasoline is highly ammable and explosive.
• Gas expands and contracts with dierent
temperatures.
• In case of a gas re, do not attempt to extinguish the
ame if the fuel shuto 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.
Liquid Petroleum Gas (Propane/LPG)
• LPG/Propane is highly ammable and explosive.
• Flammable gas under pressure can cause a re 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 re, do not attempt to
extinguish unless the fuel supply can be shut o.
• 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.
When starting generator:
• Make sure that the gas 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 and propane tank are on a

USING EFFICIENCY MODE
The inverter is equipped with an eciency mode switch
to minimize fuel consumption. In eciency mode, the
inverter will sense the load and adjust the engine RPM
to the current load requirements. Eciency mode
should be used only after the inverter has been warmed
up to operating temperature.
1. To turn on the eciency mode, press the switch to
the ON position).
2. If no load is present, the inverter RPM will drop
down to an idle speed.
3. As a load is applied, the inverter will sense the load
and engine RPM will increase according to the load
applied.
4. To run the inverter at maximum power and RPM,
press the eciency mode switch to the OFF
position.
OVERLOAD RESET
An electrical overload or short circuit will trip the
overload protection system by disconnecting the
generator’s AC output even though the engine is still
running. If this occurs, the overload alarm light will be
illuminated red and the output indicator light will be o.
The AC output can be restored as follows:
1. Turn o and unplug any electrical devices or
cords from the 120-Volt AC and 5-Volt DC USB
receptacles on the control panel.
2. Press the generator reset button on the control
panel until the overload alarm light goes o and the
output indicator light is illuminated green.
3. Check that the intended electrical running and
starting loads do not exceed the generator’s
capacity or have a licensed electrician rectify any
fault causing a short circuit in the load.
4. Reconnect any electrical devices or cords to the
receptacles on the control panel and then turn on
the electrical loads as required.
SWITCHING FUEL SOURCES
PLEASE REVIEW FUEL SAFETY
SECTION ON PAGE 6
The below assumes that the propane fuel line is already
attached to the generator securely and safely.
While the unit is running simply turn the FUEL
SELECTOR knob to the desired fuel source. If you
want to switch from gasoline to propane make sure the
propane tank valve is open before you switch. When
you move from propane to gasoline shut the propane
valve after you have switched to gas.
NOTICE
If you do not plan on operating the unit on propane do not leave
the propane tank valve open.
When starting on propane the engine may run rough for a few
seconds while it purges gasoline in the carburetor.
If the engine fails when switching fuel sources simply restart the
unit on the fuel source that you switched to.
STOPPING THE INVERTER

POWER OUTPUT AND DEMAND
The generator should not be run completely unloaded
for extended periods otherwise the engine may be
damaged. It is recommended that the generator should
always be operated with at least one-third of its rated
120-Volt AC power output. 120-Volt AC devices have
two dierent electric power demands that must be
taken into consideration, namely the running power and
the starting/peak power. Both are measured in Watts
(typically abbreviated as “W”).
The steady state continuous load is the running power
demand and this is often marked on the device near its
model number or serial number. Sometimes the device
might only be marked with its voltage (i.e. 120 V) and
current draw (e.g. 6 Amp or 6 A), in which case the
running power demand in Watts can be obtained by
multiplying the voltage times the current, e.g. 120 V
× 20 A = 2,400 W.
Simple resistive 120-Volt AC devices such as
incandescent bulbs, toasters, heaters, etc. have no extra
power demand when starting, and so their starting power
demands are the same as their running power demands.
More complex120-Volt AC devices containing inductive
or capacitive elements such as electric motors have a
momentary extra power demand when starting, which can
be up to seven times the running power demand or more.
Manufacturers of such devices rarely publish this starting
power demand and so it’s often necessary to estimate it.
A rule of thumb for devices tted with an electric motor is
to apply a starting power multiplier of
1.2 for small hand-held or portable devices and a value
of 3.5 for larger stationary devices. For example, a 900 W
angle grinder can be assumed to have a starting power
demand of at least 1.2 × 900 W, which equals 1,080 W.
Similarly, a 1,650 W air compressor can be assumed to
have a starting power demand of at least 3.5 × 1,650 W,
which equals 5,775 W.
To prevent overloading of the generator’s 120-Volt
AC system:
1. Add up the running power demand of all the 120-Volt
AC devices that will be connected to the generator
at one time. This total must not be greater than the
generator’s specied running power output.
2. Add up the running power demand again, but for
the largest motor-driven device use the value of its
starting power demand instead of its running power
demand. This total must not be greater than the
generator’s specied starting power output.
3. The total running power demand of all the devices
that will be connected to any one of the generator’s
outlets must not exceed the generator’s specied
running power output or 3,700 W, whichever is the
lesser.
TRANSPORTING THE GENERATOR
The generator should be stopped and both the fuel
control switch and fuel cap vent should be turned to the
OFF position before transporting the generator. Keep
the unit level during transport to minimize the possibility
of fuel leakage or, if possible, drain out the fuel prior to
transport.
If the generator has been operating, allow the unit to
cool down before loading it onto the transport vehicle.
The iGen4500’s wheels are only intended for ease of
moving the generator around by hand. The wheels are
not suitable for towing the generator either on or o-
road.
Use only the generator’s xed handle(s) for lifting the
unit or attaching any load restraints such as ropes or
tie-down straps. Do not attempt to lift or secure the
generator by holding onto any of its other components.
The iGen4500 is also equipped with an extendable
handle. To deploy it, push on the locking button and
pull on the handle until it’s fully extended. To stow it,
push on the locking button and push on the handle until
it’s fully retracted. Only extend or retract the handle
while the generator is stationary and resting on a
horizontal surface.
The extendable handle is intended for ease of wheeling
the generator around by hand. Do not use the
extendable handle to lift the generator entirely o the
ground, tow it or up-end it.

CAUTION
Avoid skin contact with engine oil or
gasoline. Prolonged skin contact with
engine oil or gasoline can be harmful.
Frequent and prolonged contact with
engine oil may cause skin cancer.
Take protective measures and wear
protective clothing and equipment.
Wash all exposed skin with soap and
water.
WARNING
Failure to perform periodic
maintenance or not following
maintenance procedures can cause
the inverter to malfunction and could
result in death or serious injury.
NOTICE
Periodic maintenance intervals vary depending on
inverter operating conditions. Operating the inverter
under severe conditions, such as sustained high-
load, high-temperature, or unusually wet or dusty
environments, will require more frequent periodic
maintenance. The intervals listed in the maintenance
schedule should be treated only as a general
guideline.
WARNING
Avoid accidentally starting the inverter
during maintenance by removing
the spark plug boot from the spark
plug. For electric start inverters, also
disconnect the battery cables from the
battery (disconnect the black negative
(-) cable rst) and place the cables
away from the battery posts to avoid
arcing.
Allow hot components to cool to
the touch prior to performing any
maintenance procedure.
Internal pressure can build in the
engine crankcase while the engine
is running. Removing the oil ll 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 ll plug/dipstick.
Always perform maintenance in a well-
ventilated area. Gasoline fuel and fuel
vapors are extremely ammable and
can ignite under certain conditions.

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 ow of fuel, preventing an engine
from starting after a prolonged storage period.
Proper care should be taken to prepare the inverter for
any storage
1. Make sure battery switch is OFF.
2. Clean the inverter.
3. Siphon all gasoline from the fuel tank as best as
possible.
MAINTENANCE
WARNING
Before attempting to service or troubleshoot the generator, the owner or service technician must rst 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 certication or product warranty, serious personal injury, property damage or even death.
TROUBLESHOOTING
PROBLEM POTENTIAL CAUSE SOLUTION
Engine is running, but no
electrical output
1. Circuit breakers are tripped. 1. Reset the circuit breakers and check for
overload condition.
2. The power cord’s plug connector is not fully
engaged in the generator’s outlet.
2. Verify plug connector is rmly engaged in
the generator’s outlet.
3. Faulty or defective power cord. 3. Replace power cord.
4. Faulty or defective electrical appliance. 4. Try connecting a known good appliance
to verify the generator is producing electrical
power.
5. If trying 1-4 above does not solve the
problem, the cause might be the generator has
a fault.
6. Take the generator to your nearest
authorized service dealer.
Engine runs
erratic; does not hold a
steady RPM.
1. Dirty air lter. 1. Clean the air lter.
2. Applied loads maybe cycling on and o. 2. As applied loads cycle, changes in engine
speed may occur; this is a normal condition.
3. If trying 1-2 above does not solve
the problem, the cause might be a
fault in the inverter.
3. Take the generator to your nearest
authorized service dealer.

TROUBLESHOOTING
Inverter suddenly
stops running.
1. Inverter is out of fuel. 1. Check fuel level. Add fuel if necessary.
2. The low oil shut down switch has stopped the
engine.
2. Check oil level and add oil if necessary.
3. Too much load 3. Restart the inverter and reduce the load.
Frost on the propane tank
or regulator
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 lled. 3. If you suspect your propane fuel tank
has been overlled, discontinue operation
immediately and return the propane fuel tank to
the place of purchase or relling.
Propane fuel smell
1. Fuel regulator or fuel hose and ttings 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 qualied
technician.
3. Residual fuel from the carburetor dispersing after
operation.
3. Normal, no remedy is needed.
Poor performance
or engine stalling on
propane
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 o. Start the engine and
allow the engine to run until the fuel has been
consumed in the carburetor. Begin propane start
up procedure.
