GENERATOR SAFETY WARNINGS
DANGER! CARBON MONOXIDE
Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monoxide (CO). This
is a poison gas you cannot see or smell. If you can smell the generator exhaust, you are breathing CO. But even
if you cannot smell the exhaust, you could be breathing CO.
NEVER use a generator inside homes, garages, crawl spaces, or other partially enclosed areas. Deadly levels
of carbon monoxide can build up in these areas. Using a fan or opening windows and doors does NOT supply
enough fresh air. ONLY use a generator outside and far away from windows, doors, and vents. These openings
can pull in generator exhaust.
Even if you use a generator correctly, CO may leak into the home. ALWAYS use a battery-powered or battery-
backup CO alarm in the home. If you start to feel sick, dizzy, or weak after the generator has been running, move
to fresh air RIGHT AWAY. See a doctor. You may have carbon monoxide poisoning.
WARNING! RISK OF EXPLOSION. HIGHLY FLAMMABLE: This generator may emit highly flammable and
explosive gasoline vapors, which can cause severe burns or even death, if ignited. A nearby open flame can lead
to explosion even if not directly in contact with gasoline.
• Do not operate near open flame, heat, or any other ignition source. Do not smoke near the generator.
• Always operate on a firm, level surface.
• Always turn generator off before refueling. Allow generator to cool for at least 2 minutes before removing
fuel cap. Loosen cap slowly to relieve pressure in tank.
• Do not overfill fuel tank. Gasoline may expand during operation. Do not fill to the top of the tank. Allow for
expansion. Always check for spilled fuel before operating.
• If fuel spills, move the generator at least 30 feet away from the spill and wipe clean any spilled fuel before
starting the engine.
• Empty fuel tank before storing or transporting the generator.
WARNING! If this generator is used as a supply for a building’s wiring system, the generator must be in-
stalled by a qualified electrician and connected to a transfer switch as a separately derived system in accordance
with all applicable laws and electrical codes and the National Electrical Code, NFPA 70. The generator shall be
connected to a transfer switch that switches all conductors excluding the equipment grounding conductor. The
frame of the generator shall be connected to an approved grounding electrode.
WARNING! This product can expose you to chemicals including carbon monoxide and engine exhaust,

to perform any of the steps please call 1-847-429-9263 M-F 8-5 CST for customer service. Failure to perform these
steps properly can damage the generator or shorten its life.
STEP 1 - ADD / CHECK OIL
The generator is shipped without oil. User must add the proper amount of oil before operating the generator for the
first time. The oil capacity of the engine crankcase is 16.9 fl. oz (0.5 L).
• 30W Engine Oil
Temperatures above 40°F
• 10W-30 Engine Oil
Temperatures between 0°F - 40°F
• Synthetic 5W-30 Engine Oil
All temperature ranges
ENGINE OIL RECOMMENDATIONS
Select good quality detergent oil bearing the American Petroleum Institute (API) service classifications
SJ, SL, or SM (synthetic oils may be used). Select the SAE viscosity grade of oil that matches the
expected operating temperature.
CAUTION! Keep the generator level. Tilting the generator to
assist in filling will cause oil to flow into the wrong areas of the
engine and cause damage.
1. Open the side panel (to the right of the control panel) by twist-
ing the side panel access knobs (Fig. 2 - 1). Remove and wipe
the oil dipstick with a clean rag. Insert the dipstick into the oil fill
opening without screwing it in.
2. Remove the dipstick to check the oil mark on the dipstick (Fig.
3). Add oil if the oil mark covers less than one half of the dipstick.
3. Slowly add oil and repeat step 2 until the oil mark measures
between the upper limit mark and halfway mark of the dipstick. Do
not overfill the crankcase.
4. Wipe clean any oil leaks and firmly tighten the dipstick.
CAUTION! For subsequent operation, the oil
level should be checked before each use, or
after every 8 hours of operation. The gen-
erator is equipped with a low-oil sensor and
will not start without a sufficient amount of
oil. Follow the instructions on the next page
to check the oil level.

• If fuel spills, move the generator at least 30 feet away from the spill and wipe clean any spilled fuel before
starting the engine.
• Empty fuel tank before storing or transporting the generator.
STEP 2 - ADD / CHECK FUEL
ONLY use fresh (within 30 days from purchase), lead-free
gasoline with a minimum of 87 octane rating. The genera-
tor performs best with ethanol-free gasoline. DO NOT use
gasoline with over 10% ethanol.
The capacity of the fuel tank is 1.53 gallons (5.8 L). Do not
mix oil with gasoline.
TO ADD GASOLINE:
Use fresh (within 30 days from purchase), lead-free gaso-
line with a minimum of 87 octane rating. The generator per-
forms best with ethanol-free gasoline. DO NOT use gasoline
with over 10% ethanol. The capacity of the fuel tank is 1.53
gallons. Do not mix oil with gasoline.
1. Place the generator on a level surface. Make sure the
engine is off before adding or checking the fuel.
2. Unscrew the fuel cap (Fig. 4 - 1) and set it aside. The fuel
cap may be tight and hard to unscrew.
3. Slowly add unleaded gasoline to the fuel tank. Be careful
not to overfill. Reinstall fuel cap and wipe clean any spilled
gasoline with a dry cloth.
NOTE: Do not fill the fuel tank to the very top. If you do so,
gasoline will expand and spill during use, even with the fuel
cap in place.
4. Reinstall fuel cap and wipe clean any spilled gasoline
with a dry cloth.
IMPORTANT:
• Avoid getting dirt or water into the fuel tank.
• Keep gasoline away from sparks, open flames,
pilot lights, heat, and other sources of ignition.
• Gasoline can age in the tank and make starting
difficult. Never store the generator for more
than 2 months with fuel in the tank.
• Never use an oil/gasoline mixture.
• Never use old gasoline.
FUEL OPTION A: GASOLINE
14
FUEL OPTION B: LIQUID PETROLEUM GAS (LPG)
To connect your generator to an LPG cylinder:
1. Take off the safety caps from the cylinder valve, genera-
tor mounted regulator, and regulator connecting hose ends.
2. With the LPG tank valve closed, attach the LPG regulator
connecting hose (Fig. 5 - 1) to the valve. Turn the plastic
coupling from the hose right (clockwise) to tighten hose
assembly onto the LPG tank.
3. Remove the protective cover from the LPG inlet (Fig. 6 -
1) on the generator. Push the connector on the other end of
the regulator hose into the LPG inlet until it clicks into place.
4. Turn the LPG tank valve ON and check for leaks by spray-
ing soapy water to check connections. If bubbles appear,
become larger in size, or increase in number, a leak exists.
This MUST be corrected before using generator. Contact
WEN customer service at 1-847-429-9263, M-F 8-5 CST, or
email [email protected] for assistance.
NOTE: If you would like to purchase other accessories for

PREPARATION
WARNING! Failure to properly ground the
generator increases your risk of electric shock.
WARNING! To prevent serious injury from
fire, follow the kit installation procedures in a
well-ventilated area away from ignition sources.
If the engine is hot from use, shut the engine off
and wait for it to cool before proceeding. Do not
smoke near the generator. Warranty will be void
if adjustments are not made for high altitude use.
CAUTION! UNINSTALL the high altitude kit when
operating at altitudes below 2000 feet.
NOTE: Grounding wire and grounding rods
are not included with the generator. A general-
ly acceptable grounding wire is a No. 12 AWG
(American Wire Gauge) stranded copper wire.
Grounding codes can vary by location. Contact a
local electrician to check the area codes.
Fig. 7
1
STEP 3 - GROUND THE GENERATOR
To reduce the risk of electric shock and to maximize safety,
the generator should be properly grounded.
1. Attach one end of the grounding wire to the grounding
nut (Fig. 7 - 1). Tighten the nut to secure the grounding
wire.
2. Connect the other end of the grounding wire to a copper,
brass, or steel-grounding rod that is driven into the earth.
HIGH ALTITUDE OPERATION ABOVE 2000 FEET
The fuel system on this generator may be affected by opera-
tion at high altitudes. Proper operation can be ensured by
installing an altitude kit at altitudes higher than 3000 feet
above sea level. At elevations above 9800 feet, the engine
may experience a decrease in performance, even with the
proper altitude kit. Operating this generator without said kit
may increase the engine’s emissions and decrease both fuel
economy and performance.
This kit should be installed by a qualified mechanic. You can
order the kit at wenproducts.com by searching part number
DF360iX-HA39. Refer to the instructions included with your
altitude kit for more information about installation.
AUTO FUEL SELECTION
Your generator is equipped with Auto Fuel Selection Technology. What this means is that the generator will auto-
matically select the fuel source (LPG or gasoline) depending on availability. LPG is prioritized; this means that if a
propane tank with enough LPG is connected, the generator will automatically use LPG. If no propane tank is con-
nected, the generator will use gasoline (if there is gasoline in the fuel tank). The LPG regulator hose must be discon-
nected for the generator to switch to gasoline. If the LPG regulator hose is connected and you run out of LPG, the
generator will not automatically switch to gasoline.
NOTE: Make sure the generator can handle the load(s) you plan to connect. The generator can provide more power
when running on gasoline than on LPG. Consult the specifications table on p. 3, as well as the “Calculating the Watt-
age of Your Device(s)” chart to ensure that your load(s) will not exceed the rated wattage for a particular fuel. See
also the “Switching Fuels” section for more information.
16
CAUTION!
Disconnect all electrical loads from the generator before attempting to start.
Before starting the generator, make sure you have read and performed the steps in the “Preparation” section of this
manual, pages 12-14. If you are unsure about how to perform any of the steps in this manual please call 1-847-
429-9263 M-F 8-5 CST for customer service.
To maximize safety, ALWAYS ground the generator before using it. See page 16, “GROUND THE GENERATOR”.
Use a ground fault circuit interrupter (GFCI) in highly conductive areas such as metal decking or steel work. GFCIs
are available in-line with some extension cords.

PARALLEL OPERATION
The parallel connection feature (Fig. 12 - 1) allows you to connect
two WEN generators to increase the total available electrical power.
The “Parallel Connection Kit” can be purchased from wenproducts.
com.
Follow the instructions included with your WEN parallel connection
kit for proper installation and operation.
ENGINE BREAK-IN PROCEDURE
The procedure below should be followed when you receive your gen-
erator in order to prolong the engine’s service life. This procedure
helps to seat the piston rings properly in the cylinder, and will reduce
overall wear on the engine.
For the first 8 hours of operation, vary the load, but keep it at or be-
low 50% of the generator’s rated wattage, if possible. If your genera-
tor is equipped with an Eco-mode switch (only applicable for certain
inverter generators), engage Eco-mode periodically during the first
8 hours. After the first 8 hours, change the oil, then change it again
after the first 25 hours. You may run the generator at full load af-
ter the 8-hour oil change. Refer to the Recommended Maintenance
Schedule in Table 4 for the full maintenance schedule.
ECO-MODE SWITCH
This generator is equipped with an Eco-Mode Idle Control Switch (Fig. 8 - 1). Engaging the switch automatically ad-
justs the engine to match the load. When the electrical load changes, the generator engine will automatically speed
up and slow down as needed. This reduces fuel consumption and noise levels.
Keep this switch engaged when the power load requirement is less than 2000W. Do not engage the Eco-Mode
Switch when the total load is more than 2000W. The generator engine must run at full speed to supply power for
anything over 2000W.
OIL LEVEL SHUTDOWN
The low oil indication light on the data meter (Fig. 11 - 1) will turn on to remind you that the engine oil level is low
and need to be refilled. The generator is equipped with a low oil pressure shutoff that will automatically stop the
engine when the oil level is too low to protect the unit from damage. The oil level of the engine should be checked
before each start to ensure that the engine crankcase contains sufficient lubricant.

USING YOUR GENERATOR
CALCULATING THE WATTAGE OF YOUR DEVICE(S)
Connect electrical devices running on AC current according to their wattage requirements. Calculate the total run-
ning wattage and starting wattage of the device(s) you wish to connect, and MAKE SURE that they are within the
capacity of your generator and the capacity of each individual outlet.
Generator
Wattage
Capacity
GENERATOR RUNNING (RATED) WATTS GENERATOR STARTING (SURGE) WATTS
Gasoline: 2900W Gasoline: 3600W
LPG: 2600W LPG: 3500W
What this means:
The generator can produce a maximum of
2900W / 2600W on a continuous basis to
supply ongoing power to your electronic de-
vices.
NOTE: Also check the rated amperage for
each outlet and make sure not to overload
the individual outlets.
What this means:
Some devices such as box fans require short
bursts of extra power in addition to the rated
wattage listed by the device to start their mo-
tors.
The generator can produce a maximum watt-
age of 3600W / 3500W for a short period of
time (seconds) to cover the extra starting
power required by your electronic devices.
Electronic
Device
Wattage
Calculation
Find the wattage information of each device you plan to connect. The information should be
listed on the device or in its instruction manual, or you may refer to page 22, Table 2.
The wattage can be calculated using this equation: Watts = Volts x Amperes
To calculate the total running watts of your
devices:
+ Add up the running wattages of all the
device(s) you plan to connect.
= The total running (rated) wattage.
This wattage should NOT exceed the run-
ning wattage of 2900W / 2600W.
It is recommended to maintain a load at or
below 2610W / 2340W (90% of the rated
output) to ensure steady voltage output and
to prolong the generator’s lifespan.
To calculate the total starting watts of your
devices:
+ Add up the total running wattage of all the
device(s) you plan to connect.
+ Add the single highest ADDITIONAL start-
ing wattage out of the device(s) you plan to
connect.
= The total starting (surge) wattage.
This wattage should NOT exceed the starting
wattage of 3600W / 3500W.
If any of either of the total calculated running watts or starting watts is higher than the capac-
ity of your generator, adjust the load until both wattage requirements are met. Otherwise you
will overload the generator, and cause damage to the engine and your electrical device(s).

USING YOUR GENERATOR
CONNECTING ELECTRICAL DEVICES
When the rated wattage requirement of each electrical device has been determined, add these numbers to find the
total rated wattage needed. If this number exceeds the rated wattage (2900W) of the generator, DO NOT connect all
these devices. Select a combination of electrical devices with a total rated wattage lower than or equal to the rated
wattage of the generator.
CAUTION! Become familiar with the markings on the control panel (Fig. 13) before connecting electrical
devices. Do not connect 50 Hz loads to the generator.
1. Before connecting electrical devices, allow the generator to run for a few minutes to stabilize the speed and volt-
age output.
2. Make sure that all devices are turned off. Start plugging in each electric device, from the highest wattage to the
lowest. Check the power indicator light (green) to ensure the generator is producing power.
3. Do not overload the generator or individual panel receptacles. If an overload occurs, the overload indication light
(red) will activate. If it is flashing, turn off and unplug one load. If it is solid (not flashing), the generator will cut
off power to protect itself. Unplug all electrical devices and then press the reset button to reset the entire circuit,
or press the circuit breaker to reset the DC circuit. Check the total wattage of the devices and reduce the load if it
exceeds the capacity of the generator. Then, plug the loads back in one by one.
NOTE: If the reset button or circuit breaker does not reset, wait several minutes and try again. If problem still per-
sists, please call 1-847-429-9263 M-F 8-5 CST.

WARNING! Generator should only be connected to electrical devices, either directly or with an extension
cord. NEVER CONNECT TO A BUILDING ELECTRICAL SYSTEM without a qualified electrician and connected to
a transfer switch as a separately derived system. Such connections must comply with local electrical laws and
codes. Failure to comply can create a back-feed, which may result in serious injury or death to utility workers.
NOTE: For power outages, permanently installed, stationary generators are better suited for providing backup
power to your home. Even a properly connected portable generator can become overloaded. This may result in
overheating or stressing the machine’s components, possibly leading to generator failure.
24
USING YOUR GENERATOR
CO SENSOR INFORMATION
The CO Watchdog carbon monoxide monitoring system (Fig.
14 - 1) measures the accumulation of poisonous CO gas
while the generator is running. If the level of CO gas gets too
high, the CO Watchdog system will automatically shut down
the generator. This system is not a substitute for an indoor
CO alarm.
Whenever the CO Watchdog system shuts down the genera-
tor, the LED on the generator control panel (Fig. 14 - 1) will
blink red for at least 5 minutes after the generator is shut
down. If you notice that the LED is blinking red, vacate the
area immediately. Go to an open, outdoor area. Ventilate
the area around the generator thoroughly before returning.
Let the generator stay shut down for a few minutes before
restarting the engine. This should allow carbon monoxide to
dissipate from the area. If you restart the generator and the
CO Watchdog detects that CO levels are still too high, it will
shut down the generator again. If CO levels are low enough,
the generator will run normally.
1
Ensure that the generator is located in an open outdoor area, with the exhaust pointing away from occupied struc-
tures, and pointing away from the prevailing winds, such that those winds do not blow engine exhaust towards the
sensor module. If anyone experiences dizziness, headaches, nausea, fatigue, or other symptoms of CO poisoning,
get to fresh air immediately and seek the attention of a qualified medical professional. Follow all other directions in
this manual regarding the connection and disconnection of electrical devices when starting or shutting down the
generator.
When starting the generator, the CO Watchdog LED on the panel may flash. This indicates that the system is running
a self-test procedure, and does not indicate a problem.
If the CO Watchdog LED on the panel is yellow, a system error has occurred, or the CO sensor has reached the end
of its life. Contact WEN customer service (1-847-429-9263, M – F 8 – 5 CST, or [email protected])
for assistance.
When operating your generator, please note the following:
• The CO Watchdog does not discriminate in its input; any source of carbon monoxide in the area around the genera-
tor could cause it to activate. If the CO Watchdog LED is blinking red, safety measures should be taken immediately.
• Tampering with, disconnecting, or bypassing the CO sensor could cause hazardous conditions, including but not
necessarily limited to injury or death, and will void your warranty. The generator will not run with the CO sensor
disconnected or bypassed, or if the CO sensor indicates an error.
• The CO sensor has a lifetime of about 7 years, and is capable of monitoring its lifetime. If your generator shows
an error light several years after purchase, it may be time to replace the CO sensor. Contact WEN customer service
for assistance.
NOTE: if the generator is oriented so that the
engine exhaust is blown towards the CO sensor,
the generator may shut down.

STOPPING YOUR GENERATOR
SHUTTING OFF THE GENERATOR
1. Turn off all electrical devices and then unplug the devices from the generator.
CAUTION! Unplugging running devices can cause damage to the generator. Never stop the engine with elec-
trical devices connected and running.
2. Allow generator to run at no load for a few minutes to stabilize
internal temperatures.
3. Turn the 4-in-1 switch (Fig. 13 - 1) to the “FUEL OFF” position.
4. If using LPG, turn the LPG tank valve OFF and remove the LPG
regulator hose from the tank and inlet on the generator. Push the
collar on the LPG quick-connector back to release the end of the
LPG regulator hose.
4. The engine will continue to run until the majority of the fuel in the
carburetor is consumed, which takes a few minutes. It will then shut
off automatically. This feature helps to prevent the carburetor from
being clogged by stale fuel, extending your generator’s lifespan.
5. In case you are in a hurry and do not want to wait for the generator
to automatically shut down, turn the 4-in-1 switch to the “ENGINE
OFF” position and the generator will shut off right away. However,
this method will leave stagnant fuel in the carburetor, possibly caus-
ing blockages, a shortened lifespan, and other maintenance issues. If
this approach is frequently taken, make sure to drain your carburetor
before any long storage periods.
WARNING! Allow the generator to cool for several minutes
before touching areas that become hot during use.
CAUTION! Allowing gasoline to sit in the fuel tank for long
periods of time can make it difficult to start the generator in the fu-
ture. Never store the generator for extended periods of time (over
2 months) with fuel in the fuel tank. Refer to “Storing the Genera-
tor” on page 28.

IMPORTANT GENERATOR MAINTENANCE TIPS:
• Drain your carburetor after each use and before storage to prevent it from clogging.
• Do not store the generator with fuel inside the tank for more than 2 months - the fuel will go bad.
• Run the generator for at least 20 minutes every month to maximize its lifespan.
CLEANING THE GENERATOR
Keep the generator clean to prevent improper operation or machine damage from dirt and debris. Inspect all venti-
lation openings on the generator. These openings must be kept clean and unobstructed. If the generator becomes
dirty, use a damp cloth to wipe exterior surfaces. Use a soft bristle brush to loosen dirt and oil and use a vacuum to
pick up loose dirt. Use low pressure air (not to exceed 25 PSI) to blow away dirt.
CAUTION! Never clean the generator when it is running! Never clean with a bucket of water or a hose. Water
can get inside the working parts of the generator and cause corrosion or a short circuit.
NOTE: Failure to properly maintain the generator will void the warranty.
27
MAINTENANCE
WARNING! Make sure generator is shut off before performing any inspection or maintenance procedures.
CHECKING / ADDING OIL
Check the oil level of the generator according to the Recommended Main-
tenance Schedule in Table 4. The oil level should be checked before each
use or every 8 hours of operation. The oil capacity of the generator engine
is 16.9 fl. oz. (0.5 L). Add oil when the oil level is low.
For proper type and weight of oil refer to “ADD / CHECK OIL” section. The
generator is equipped with an automatic shutoff to protect it from run-
ning on low oil. To check the oil level:
1. Make sure the generator is on a level surface. Do not tilt the generator
to assist in filling, as oil will flow into engine areas and cause damage.
Keep generator level!
2. Open the side panel (to the right of the control panel) by twisting the
side panel access knobs (Fig. 16 - 1). Remove and wipe the oil dipstick
(Fig. 17) with a clean rag. Insert the dipstick into the oil fill opening with-
out screwing it in.
3. Insert the dipstick into the oil fill opening without screwing in. Remove
the dipstick to check the oil mark. Add oil if the oil mark covers less than
one half of the dipstick.
4. Using a funnel or appropriate dispenser, slowly add more oil. Repeat
step 3 until the oil mark measures between the upper limit mark and half-
way mark of the dipstick. Do not over fill the crankcase.
5. Reinstall dipstick and wipe clean any spilled oil with a rag.
DRAINING / CHANGING THE OIL
Change the oil according to the Recommended Maintenance Schedule in Table 4. Change the oil more often if oper-
ating under heavy load or high ambient temperatures. It is also necessary to drain the oil from the crankcase if it has
become contaminated with water or dirt. Changing the oil when the engine is warm allows for complete drainage.
Drain the oil from the generator according to the following steps.
1. Place generator on an elevated platform such as table or desk. Prepare a container underneath the oil fill to catch
the oil as it drains.
2. Open the side panel. Remove the dipstick and tilt the generator towards you to allow the oil to drain from the
engine completely.
3. Reinstall the oil dipstick and tighten it securely. Wipe clean any oil spillage and close the side panel.
NOTE: Do not dispose of used motor oil in the trash or down a drain. Please call a local recycling center or auto
garage to arrange proper oil disposal.

4. Visually inspect the spark plug for cracks or excessive electrode
wear. If the electrodes are worn or burned, or porcelain is cracked,
replace with a Torch E6RTC (NGK BPR6HS) spark plug (Part No.
56360iX-002), available at wenproducts.com.
5. If re-using the spark plug, use a wire brush to clean any dirt
from around the spark plug base then re-gap the spark plug.
6. Measure the plug gap with a wire gauge (Fig. 19). The gap
should be 0.023 - 0.031 in. (0.6 - 0.8 mm). Carefully adjust the
gap if necessary.
7. Screw the spark plug back into the spark plug hole by hand.
After the spark plug is properly seated, use the spark plug wrench
to tighten it.
NOTE: The recommended tightening of the spark plug is 1/2 to 3/4
of a turn after the spark plug gasket contacts the spark plug hole,
or 11.1-14.7 ft-lbs (15 - 20 Nm). Do not over-tighten the spark
plug.
8. Reinstall the spark plug boot over the spark plug.

TRANSPORTATION & STORAGE
WARNING! Avoid direct sunlight inside a vehicle. If the generator is left in an enclosed vehicle for many
hours, the high temperature could cause the fuel to vaporize and result in a possible explosion.
WARNING! Store the generator upright in a cool and dry location, away from sources of heat, open flames,
sparks or pilot lights.
TRANSPORTING THE GENERATOR
To prevent fuel spillage when transporting, be sure to perform the following:
1. Tighten the fuel cap.
2. Flip the 4-in-1 switch to the “ENGINE OFF” position.
3. Drain the fuel tank if possible. Refer to page 28, “Draining the Fuel Tank.”
4. Keep the generator upright. Never place the generator on its side or upside down - doing so could damage the
internal components of the generator and make it difficult to start.
STORING THE GENERATOR
Shut off the generator and allow the unit to cool to room temperature before storing it. NEVER place any type of
storage cover on the generator while it is still hot. Do not obstruct any ventilation openings.
Follow the procedures below for properly storing your generator. We highly recommend running your generator
once a month for 20 to 30 minutes. Plug in a small load in to ensure there is proper power output.
PRODUCT DISPOSAL
Do not dispose of a used generator or parts with your household waste. This product contains electrical or elec-
tronic components that should be recycled. Please take this product to your local recycling facility for responsible
disposal to minimize its environmental impact.
Do not dispose of used oil or fuel in the trash or down a drain. Please contact your local recycling center or auto
garage to arrange proper oil/fuel disposal.
For Short Periods (30 to 60 Days):
• Drain the carburetor. Refer to page 30, “DRAINING THE
CARBURETOR.”
• Add fuel stabilizer: Follow the suggested portions and
instructions of your preferred stabilizer. Run the engine for
15 to 20 minutes, allowing the fuel stabilizer to mix with the
gasoline and circulate through the carburetor, and then top
off with fuel. Filling the fuel tank full reduces the amount of
air in the tank and helps fight deterioration of fuel.
For Extended Periods (Over 60 Days):
• Drain the fuel tank and carburetor (see
“DRAINING THE FUEL TANK”). Never
store generator with fuel in the tank for
more than two months.
