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, crawlspaces, or other partly 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 batterybackup 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: The exhaust from this product contains chemicals known to the State of California to cause
cancer, birth defects, or other reproductive harm.
WARNING: 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 it isn’t directly in
contact with gasoline.
• Do not operate near open flame.
• Do not smoke near 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.
• Empty fuel tank before storing or transporting the generator.
WARNING: This generator produces powerful voltage, which can result in electrocution.
• ALWAYS ground the generator before using it (see the “Ground the Generator” portion of the
“GENERATOR PREPARATION” section).
• Generator should only be plugged into electrical devices, either directly or with an extension cord.

GENERATOR PREPARATION
USING THE GENERATOR FOR THE FIRST TIME
The following section describes steps necessary to prepare the generator for use. If after reading this section, you are unsure about how to perform any of the steps please call (800) 232-1195 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 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 0.37 quarts (0.35 liters). For general use (above 40° F),
we recommend 30W, 4-stroke engine oil.
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.) Use the ASE viscosity grade of oil from the following chart (Figure 1) that
matches the starting temperature anticipated before the next oil changes.
Figure 1 - Engine Oil Replacemendations
To add oil, follow these steps:
1. Make sure the generator is on a level surface. Tilting the generator to assist in filling will cause oil to flow
into engine areas and will cause damage. Keep generator level!
2. Open the access panel. Remove the dipstick from the engine. (Figure 2)
3. Add oil slowly to bring level to full. (Figure 2).
4. To check the oil level: wipe the dipstick with a clean rag. Insert the dipstick into the oil fill opening
without screwing in. Remove the dipstick to check the oil mark.
5. Slowly add more oil and repeat step 4 until the oil mark reaches to the top of the dipstick (Figure 2). Do
not over fill the crankcase. The generator is equipped with a low oil sensor and will not start if the amount
of oil is in sufficient.
6. Check for oil leaks. Tighten dipstick firmly before closing the access panel.

GENERATOR PREPARATION
Step 2 - ADD GASOLINE
WARNING: This generator may emit highly ammable and explosive gasoline vapors,
which can cause severe burns or even death if ignited. A nearby open ame can lead to
explosion even if not directly in contact with gasoline.
Use fresh (within 30 days from purchase), lead-free gasoline with a minimum of 87 octane rating. Do not mix oil
with gasoline.
To add gasoline, follow these steps:
1. Make sure the generator is on a level surface.
2. Unscrew fuel cap and set aside. NOTE: The fuel cap may be tight and hard to unscrew.
3. Slowly add unleaded gasoline to the fuel tank. Be careful not to overfill. The capacity of the fuel tank is 1
gallon. NOTE: Do not fill the fuel tank to the very top. Gasoline will expand and spill over during use even
with the fuel cap in place.
4. Reinstall fuel cap and wipe clean any spilled gasoline with a dry cloth.
IMPORTANT:
• Never use an oil/gasoline mixture.
• Never use old gasoline.
• Avoid getting dirt or water into the fuel tank.
• Gasoline can age in the tank and make starting difficult. Never store generator for extended periods of time
with fuel in the tank.
Step 3 - GROUND THE GENERATOR
WARNING: Failure to properly ground the generator
can result in electrocution.
Ground the generator by tightening the grounding nut on the
front control panel against a grounding wire (Figure 3). A generally acceptable grounding wire is a No. 12 AWG (American Wire
Gauge) stranded copper wire. This grounding wire should be
connected at the other end to a copper, brass, or steel-grounding
rod that is driven into the earth. Wire and grounding rods are not
included in generator contents.

USING THE GENERATOR
WARNING: When this generator is used on a building’s wiring system, the generator must be installed by a qualified electrician and connected to a transfer switch as a separately derived system in accordance with the National
Electrical Code, NFPA 70. The generator shall be connected to a transfer switch that switches all conductors
other than the equipment grounding conductor. The frame of the generator shall be connected to an approved
grounding electrode.
For power outages, permanently installed stationary generators are better suited for providing backup power to the
home. Even a properly connected portable generator can become overloaded. This may result in overheating or
stressing the machine’s components, possibly leading to a generator failure.
Before connecting electrical devices, allow the generator to run for a few minutes to stabilize the speed and voltage
output.
CAUTION: Become familiar with the markings on the panel before connecting electrical devices.
Connect electrical devices running on AC current according to their wattage requirements. The chart in Figure 6
shows the rated and surge wattage of the generator.
The rated (running) wattage is the wattage the generator can produce on a continuous basis.
The surge wattage is the maximum amount of power the generator can produce for an extremely short period of
time (seconds). Many electrical devices such as refrigerators require short bursts of extra power in addition to the
rated wattage listed by the device to start their motors. The surge wattage ability of the generator covers this extra
power requirement.
Item Rated (Running) Wattage Surge Wattage
56200i 1600 2000
Figure 6 - Generator Wattage
The total running wattage requirement of the electrical devices connected to the generator should not exceed the
rated wattage of the generator itself. To calculate the total wattage requirement of the electrical devices you plan
to connect, find the rated (or running) wattage of each device. This number should be listed somewhere on the
device or in its instruction manual. If this wattage cannot be found, calculate it by multiplying the Voltage requirement by the Amperage drawn:
Watts = Volts x Amperes
If these specifications are not available, estimate the watts requirement of the device by using the chart in Figure 7.
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 of the generator, DO NOT connect all
these devices. Select a combination of electrical devices, which have a total rated wattage lower than or equal to
the rated wattage of the generator.
14
USING THE GENERATOR
CAUTION: The generator can run at its surge wattage capacity for only a short time. Connect electrical devices
requiring a rated (running) wattage equal to or less than the rated wattage of the generator. Never connect devices
requiring a rated wattage equal to the surge wattage of the generator. This can trip the circuit protectors (circuit
breakers).

MAINTENANCE & CARE
CLEANING THE GENERATOR
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 a short circuit or corrosion.
Always try to use the generator in a cool, dry place. If the generator becomes dirty, clean the exterior with a damp
cloth, a soft brush, a vacuum or pressurized air.
CHECKING THE OIL
Check the oil level of the generator according to the Recommended Maintenance
Schedule in Figure 9. The generator is equipped with an automatic shutoff to protect
it from running on low oil. The generator should be checked before each use for
proper oil level. This is a critical step for proper engine starting. To check the oil
level:
1. Make sure the generator is on a level surface.
Oil Dipstick
2. Open access panel. Clean around oil fill. Remove dipstick and wipe the
dipstick with a clean rag. 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.
3. Slowly add more oil and repeat step 2 until the oil mark reaches to the top
of dipstick (Figure 10). Do not over fill the crankcase.
4. Reinstall oil dipstick and access panel.
CHANGING/ADDING OIL
Change the oil according to the Recommended Maintenance Schedule in Figure 9. Change the oil when the engine is warm. This will allow for complete drainage. Change oil more often if operating 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. The oil capacity of the generator engine is 0.37 qts. Add oil when the oil level is low. For proper
type and weight of oil refer to “add oil” portion of the “Generator Preparation” section.
Drain the oil from the generator according to the following steps after removing the side panel.
1. Place generator on elevated platform such as table or desk. Put a container next to it to hold the used oil. Turn
the vacuum relief valve to “OFF” position.
2. Unscrew the dipstick from the engine and set aside.
3. Tilt the generator so the used oil flows from the engine into the container. Tilt some more to ensure all oil is
out of the crankcase.
Figure 10 - Oil Fill Opening,
Dipstick and Oil Level
4. Fill the crankcase with fresh oil and reinstall the dipstick. Clean any oil spillage before closing the side panel.
17
MAINTENANCE & CARE
To rell the crankcase with oil, follow these steps:
1. Make sure the generator is on a level surface. Tilting the generator to assist in filling will cause oil to flow into
engine areas and will cause damage. Keep generator level!
2. Remove the dipstick from the engine.
3. Using a funnel or appropriate dispenser, add the correct amount of oil into the crankcase. The engine is
equipped with a low oil pressure sensor and will not start if the amount of oil is insufficient.
4. Reinstall dipstick.
NOTE: Never dispose of used motor oil in the trash or down a drain. Please call a local recycling center or auto
garage to arrange oil disposal.
AIR CLEANER MAINTENANCE
Routine maintenance of the air cleaner helps maintain proper airflow to the carburetor. Occasionally check
that the air cleaner is free of excessive dirt. Refer to Recommended Maintenance Schedule in Figure 9. For air
cleaner detail, refer to Figure 11.
1. Remove the side panel.
2. Remove three screws then pull the air cleaner cartridge out in the arrow direction shown in Figure 15.
3. Check and clean the air cleaner element, replace with a new one if the element is damaged. Good element can
be washed in soapy water, dried and reused. There is no need to add oil to the element.
4. Wipe off excessive oil from the air cleaner case. Small amount of oil in the element is normal and necessary for
the engine to work properly.
5. Reinstall the air cleaner element, cartridge and access panel.
CAUTION: running the engine with dirty, damaged or missing air cleaner element will cause the engine to wear
out prematurely.

MAINTENANCE & CARE
SPARK PLUG MAINTENANCE
The spark plug is important for proper engine operation. A good spark plug should be intact, free of deposits,
and properly gapped. Refer to Recommended Maintenance Schedule in Figure 9. To inspect the spark plug:
1. Remove side panel.
2. Remove spark plug boot. Be careful not to tear insulation or wire.
3. Unscrew the spark plug from the engine using the spark plug wrench provided. There is limited space for the
wrench to turn. Use both rows of holes in the spark plug wrench to gain leverage to loosen the plug.
4. Visually inspect the spark plug for cracks or excessive electrode wear. Replace as necessary.
5. Measure the plug gap with a wire gauge. The gap should be 0.6-0.7 mm (0.024-0.028 in).
6. 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.
7. Screw the spark plug back into the spark plug hole using the spark plug wrench. Do not over-tighten spark
plug. Recommended tightening of spark plug is ½ to ¾ of a turn after spark plug gasket contacts spark plug hole.
Reinstall the spark plug boot and control panel.

MAINTENANCE & CARE
DRAINING THE FUEL TANK
Clean fuel tank each year or before storing the generator for extended periods of time. To drain the fuel tank and
carburetor:
1. Set idle control switch to “ON” position. Start generator without any device connected to it. Turn the fuel valve
to “off” position while the engine is running until it stops. This burns out the fuel in the carburetor and fuel line.
2. Set the vacuum relief valve on top of the fuel cap to “OFF” position. Drain oil from the crankcase (refer to
“changing/adding oil” section of this manual).
3. Remove the fuel cap; carefully turn the generator over to pour the gasoline in the fuel tank to appropriate con-
tainer.
4. Once fuel is drained, reinstall the fuel cap.
5. Store the emptied gasoline in a suitable place.
CAUTION: Do not store fuel for more than 3 months.
STORAGE & TRANSPORT PROCEDURES
CAUTION: Never place any type of storage cover on the generator while it is still hot.
If the generator is being stored for short periods of time (30 to 60 days), add stabilized fuel to the fuel tank until
full. NOTE: Filling the tank reduces the amount of air in the tank and helps reduce deterioration of fuel. Run
the engine for 2 – 3 minutes allowing stabilized fuel mixture to circulate through the carburetor.
When storing the generator for extended periods of time:
• Drain the fuel tank (see “Draining the Fuel Tank” in the “Maintenance” section).
• Change oil.
• Do not obstruct any ventilation openings.
• Keep the generator in a cool dry area.
When transporting generator:
• Tighten fuel cap and vacuum relief valve. Drain the fuel tank if possible (see “Draining the Fuel Tank” in
the “Maintenance” section).
• Keep the generator upright. Never place the generator side down. Doing so will make it difficult to start.
