Parallel Kit Precautions
Carbon Monoxide Safety
Carbon Monoxide
Generators are very convenient, but they can also be very
dangerous. All fuel-burning appliances and equipment release
a poisonous gas called carbon monoxide. Carbon monoxide
(also known as CO) can be dangerous for humans and pets,
even in small amounts, because it blocks oxygen from getting
into your body. Carbon monoxide poisoning can lead to death in
a very short time. It is odorless, tasteless and invisible, so you
may be exposed without knowing it. That is why carbon
monoxide is sometimes called “the silent killer.”
To prevent serious injury, death, and generator and/or
equipment damage from electric shock and fire:
1. Follow Parallel Kit instructions provided with it for
connection and use of a Parallel Kit.
2. Only connect two identical Inverter Generators together
using a Parallel Kit.
3. Connect Parallel Kit only to terminals marked “Parallel”
on the front of the Generator.
4. Do not remove or connect a Parallel Kit while the
Generator is running.
5. Do not use a Parallel Kit that is attached to only one
Generator.
WARNING
NOTE
CO Sentry
The CO Sentry system was created to protect from dangerous
carbon monoxide. Just like the detector for your home the CO Sentry
tests the air for dangerous levels of carbon monoxide. If dangerous
levels of carbon monoxide are detected this generator will
automatically shut off.
CO Sentry Indicator Lights
RED
Carbon monoxide has accumulated around the generator. After
shut off, the RED indicator light in the CO Sentry area of the control
panel will flash to provide notification that the generator was shut off
due to an accumulating CO hazard. The RED light will flash for at least
five 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 Sentry system fault occurred. When a system fault occurs, the
generator is automatically shut down and the YELLOW indicator light
in the CO auto shut off area of the control panel will flash to provide
notification that a fault has occurred. The YELLOW light will flash for
at least five minutes after a fault. The generator can be re-started,
but may continue to shut off.
WARNING
Automatic shut off accompanied with a flashing RED light in the
CO Sentry 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.

space for fuel expansion.
• To ensure that the generator runs smoothly use only FRESH,
FRESH
GASOLINE WITH AN OCTANE RATING OF 87.
• Never use old gasoline.
• Avoid getting dirt or water in the gasoline tank.
• Gasoline WILL age in the tank and make it hard to start the
generator
in the future.
• Never store generator for extended periods of time with
gasoline in
the tank.
This engine is equipped with a low oil shut-off and will stop
when the oil level in the crankcase falls below a critical level.
CAUTION
Check oil level often during the break-in period. Refer to the
Maintenance section for recommended service intervals.
NOTICE
The first 5 hours of run time are the break-in period for the
generator. During the break-in period stay at or below 50% of
the running watt rating and vary the load occasionally to allow
stator windings to heat and cool. Adjusting the load will also
cause the engine speed to vary slightly and help seat the piston
rings. After the 5-hour break-in period, change the oil.
NOTICE
Synthetic oil may be used after the 5-hour initial break-in
period. Using synthetic oil does not increase the recommended
oil change interval. Full synthetic 5w-30 oil will aid in starting in
cold < 41° F (5° C) temperatures.
NOTICE
TO PREVENT SERIOUS INJURY FROM FIRE:
Fill the gasoline tank in a well-ventilated area away from ignition
sources. If the engine is hot from use, shut the engine off and wait

For proper break-in, do not exceed 50% of the rated running watts
during the first five hours of operation.
Use supplied oil until first recommend oil change. Do not use full
synthetic oil during break in period. Full synthetic oil may prevent
proper break-in and seating of the piston rings.
Vary the load occasionally to allow stator windings to heat and cool
and help seat the piston rings.

Operation
Generator Capacity
Make sure the generator can supply enough continuous
(running) and surge (starting) watts for the devices you
will power at the same time.
The total power requirements (Volts x Amps=Watts) of
all devices 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 devices you will power at the same time.
2. Total the continuous (running) watts of these devices.
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. 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.
Do not overload the generator's capacity. Exceeding
your generator's wattage capacity can damage the
generator and/or electrical devices connected to it.

High Altitude Operation
At high altitude, the standard carburetor air/fuel
mixture will be too rich. Performance will decrease,
and fuel consumption will increase. A very rich mixture
will also foul the spark plug and cause hard starting.
Operation at an altitude that differs from that at which
this engine was certified, for extended periods of time,
may increase emissions. High altitude performance
can be improved by specific modifications to the
carburetor. If you always operate your generator at
altitudes above 5,000 feet (1,500 meters), have your
qualified technician perform this carburetor
modification. This engine, when operated at high
altitude with the carburetor modifications for high
altitude use, will again meet each emission standard.
Even with carburetor
modification, engine power will decrease about 3.5%
for each 1,000-foot (300-meter) increase in altitude.

Maintenance
Turn the generator “OFF”, wait for the engine to cool, and disconnect the spark plug cable before performing any inspection, maintenance,
or cleaning procedures.
EQUIPMENT FAILURE: Do not use damaged equipment. If abnormal noise, vibration, or excess smoking occurs, have the problem corrected
before further use.
Many maintenance procedures, including any not detailed in this manual, will need to be performed by a qualified technician for safety. If
you have any doubts about your ability to safely service the equipment or engine, have a qualified technician service the equipment
instead.

Checking and Filling Fuel
4. Add fuel, if needed.
5. Replace the Fuel Cap.
6. Wipe up any spilled fuel and allow excess to evaporate before
starting the engine. To prevent FIRE, do not start the engine
while the smell of fuel hangs in the air.
Engine Oil Change
1. Turn the generator off and allow the engine to cool for 30
minutes.
2. Place the generator on a level surface in a well-ventilated
area.
3. Place an oil drain pan under the generator and center it under
the oil drain opening.
4. Remove the oil drain plug from the generator, tilt the generator
slightly to facilitate drainage, and wait for the oil to drain
completely. Recycle used oil.
5. Clean the top of the oil fill and the area around it.
6. Add the appropriate type of oil until the oil level is at the proper
level. SAE 10
w-30 oil is recommended for general use.
Note: Make sure the generator is level when adding oil to prevent
overfilling which could cause engine damage.
7. Check engine oil level daily and add as needed. Remove and
clean the dipstick. Reinsert the dipstick but do not screw it back
in. Remove the dipstick and verify the oil is at the correct level.
8. When the engine oil is at the correct level, reinstall the dipstick
and screw it down until it is sealed. then, reinstall the right-side
panel.
TO PREVENT SERIOUS INJURY FROM FIRE: You must shut off
the engine and allow it to cool before refueling.
1. Clean the Fuel Cap and the area around it.
2. Unscrew and remove the Fuel Cap.
3. Remove the strainer and discard any dirt and debris, then
replace the strainer.
Note: Do not use gasoline that has been stored in a metal fuel
container or a dirty fuel container. It can cause particles to enter
the carburetor, affecting engine performance and/or causing
damage.
WARNING
Oil is very hot during operation and can cause burns. Wait for
the engine to cool before changing the oil.
CAUTION
• Do not attempt to run the generator with too little oil. The
engine will not start with low or no engine oil.
• Change the oil while the engine is warm but not hot. Warm
engine oil drains more quickly and thoroughly than cool oil.
Contact with hot oil will cause serious burns
NOTICE

Storage
When the generator is to remain idle for longer than 20 days,
prepare the engine for storage as follows:
1. CLEANING:
Wait for the engine to cool, open both side acess panels and blow
(or vacuum) any dirt or debris.
2. FUEL:
Gasoline Treatment/Draining the Fuel Tank
To protect the fuel tank during storage, fill the tank with fresh
gasoline that has been treated with a fuel stabilizer additive
(such as Sta-Bil, or Pri-G).
Follow fuel stabilizer manufacturer's recommendations for use.
Draining the Carburetor
Shut off gasoline flow by moving the fuel petcock under the tank,
place an appropriate container under the carburetor and carefully
remove the drain bolt from the bottom of the carburetor bowl,
allowing the fuel to drain completely. Replace the drain bolt after
draining.
Aged gasoline that has not been treated with stabilizer ahead of time
must be safely drained and disposed of, never run old gasoline
through the engine.
3. Extended storage:
a. Change engine oil.
b. Clean out the area around the spark plug. Remove the spark
plug and pour one tablespoon of engine oil into the cylinder
through the spark plug hole.
c. Replace spark plug, but leave spark plug boot.
d. Pull Recoil to distribute oil in the cylinder. Stop after one or
two revolutions when you feel the piston start the
compression stroke (when you start to feel resistance).
4. STORAGE AREA:
Cover and store in a dry, level, well-ventilated area out of reach
of children. The storage area should also be away from ignition
sources, such as water heaters, clothes dryers, and furnaces.
5. AFTER STORAGE:
Untreated gasoline will deteriorate quickly. Drain the fuel tank and
change to fresh fuel if untreated gasoline has been sitting for a
month, if treated gasoline has been stored beyond the fuel
stabilizer's recommended time, or if the engine does not start.
To prevent serious injury and fire, move the fuel petcock under the
tank to shut off gasoline supply before draining the carburetor.
WARNING
Fill the fuel tank in a well-ventilated area away from ignition
sources. If the engine is hot from use and wait for it to cool
before adding fuel. Do not smoke or vape anything.
WARNING
Use only BPR6ES (NGK) type spark plug or equivalent. Using
an incorrect spark plug may damage the engine.
NOTICE
Tighten the Spark Plug properly. If loose, the Spark Plug will
cause the engine to overheat. If overtightened, the threads in
the engine block will get damaged.
NOTICE
During extended storage periods, the engine should be started every
3 months and allowed to run for 15-20 minutes.
NOTICE
Do not clean using water. The water will gradually enter the
engine and cause damage.
