GENERAL SAFETY PROCEDURES
For any questions regarding the hazard and safety notices listed in this manual or on the product, please
call [phone] Mon-Fri 9-5 EST before using the generator.
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. Deadlylevels
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: 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.
NEVER connect to a building electrical system without a qualified electrician. 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.
•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.
•Do not use in rainy conditions.
•Do not touch bare wires or receptacles (outlets).
•Do not allow children or non-qualified persons to operate.

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.
AC Usage
Connect electrical devices running on AC current according to their wattage requirements. The chart
below shows the rated and surge wattage of the generator.
Model
Rated Wattage
Surge Wattage
PS50
900W
1000W
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.
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 wattages requirement of the device by using the
chart in next page.
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.
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

check that the air cleaner is free of excessive dirt. Refer to Recommended Maintenance Schedule in last
page. For air cleaner detail:
1. Undo the 2 bolts holding the air cleaner cover in place.
2. Remove the sponge-like elements from the casing.
3. Wipe the dirt from inside the empty air cleaner casing
4. Wash the sponge-like elements in household detergent and warm
water. Allow to dry.
5. Drip the sponge-like element in clean engine oil, squeeze out extra
oil and reinsert into the casing.
6. Attach the air cleaner cover with the 2 bolts.
CAUTION: running the engine with dirty, damaged or missing air cleaner element will cause the engine
to wear out prematurely.
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. To inspect the spark plug:
1. Remove spark plug boot. Be careful not to tear insulation or wire.
2. 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.
3. Visually inspect the spark plug for cracks or excessive electrode wear. Replace as necessary.
4. Measure the plug gap with a wire gauge. The gap should be 0.7 to 0.8 mm (0.028-0.031 in).
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. 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.
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. Turn the fuel valve to the “OFF” position.
2. Remove the fuel line between the fuel valve and carburetor. Caution: A small amount of fuel may
leak from the hose during removal.
3. Attach a fuel line (not included with the generator) to the exposed end of the fuel valve.
4. Position fuel line into an appropriate container and open the fuel valve allowing fuel to flow into the
container.
5. Once fuel is drained, shut off the fuel valve.
