a poisonous, colorless, odorless gas that can cause death or
serious injury.
Always operate on a level surface
Keep away from rain, snow or other wet conditions
Keep away from smoking materials, sparks, and other sources
of combustion when refueling.
Pre-Operation:
1. Add oil by removing the maintenance panel and inspecting the dipstick. Fill the oil reservoir
with 7.4 oz. (220 ml) of oil or to the full mark on the dipstick. Use appropriate grade,
high-detergent, premium quality, 4-stroke engine oil. Use SAE 15W-40 viscosity oil unless
operating at ambient temperatures below 32° F (0° C). For temperatures below 32° F, use
SAE 0W-40 viscosity oil. See page 14 for more information about operating at extreme
temperatures.
2. Carefully add regular unleaded automotive gasoline up to the shoulder of the filler neck. To
avoid spilling fuel, use care to not fill too quickly or over fill. Avoid getting dirt, dust, or water in
the fuel tank. Do not use a blend that contains more than 10% ethanol. Do not use gasoline
containing methanol. An octane rating of 87 or higher is recommended.
Operation:
1. Ensure that no loads have been connected to the AC receptacle.
2. Open the fuel valve.
3. Push the engine switch on the control panel to the ―ON‖ position.
4. Move the choke lever to the ―START‖ position.
5. Pull the starter grip lightly until resistance is felt, then pull briskly out. Repeat until the engine

4.2 High altitude operation
At higher altitudes, the standard carburetor air-fuel mixture will be excessively rich. Performance will
decrease, and fuel consumption will increase.
High altitude performance can be improved by installing a smaller diameter main fuel jet in the carburetor. If
you always operate the generator at altitudes higher than 5000 feet (1500 m) above sea level, have your
authorized dealer install a high altitude main jet.
Even with suitable carburetor jetting, engine horsepower will decrease approximately 3.5% for each 1000
feet (305 m) increase in altitude. The affect of altitude on the horsepower will be greater than this if no
carburetor modification is made.
Be sure to have any carburetor modification reversed before operating at lower
altitudes. Operation of the generator at an altitude lower than the carburetor is
jetted for may result in reduced performance, overheating, and serious engine
damage caused by an excessively lean air/fuel mixture.
4.3 Operating at extreme temperatures
High temperature adversely affects generator operation. Generator performance will decrease 1% for each
10°F (5.5°C) increase in temperature above 85°F (29°C). The normal operating range of this generator is 0°
to 113° F (-18° to 45°C). Although the generator can operate at 0° F (-18° C) it will be necessary to use a
lower viscosity engine oil such as SAE 0W-40. Even with 0W-40 oil, the engine will be more difficult to
start.
■ Do not operate the generator when the ambient temperature is below 0°F
(-18°C).
■ Do not operate the generator when the ambient temperature exceeds 113°F
(45°C).

5. MAINTENANCE
The purpose of the maintenance and adjustment schedule is to keep the generator in the best operating
condition.
Inspect or service as scheduled in the table below.
There are no special operating instructions for the break in period for the engine, but the oil should be
changed between the first 4 to 6 hours of operation to remove any manufacturing debris or contamination.
■ Shut off the engine before performing any maintenance. If the engine must be
run, make sure the area is well ventilated. The exhaust contains poisonous
carbon monoxide gas.
■ Use genuine Powerhouse parts or their equivalent. The use of replacement parts
which are not of equivalent quality may damage the generator.
■ When repairing or replacing the accessories of emission control system, only
use parts known to comply with EPA standards.
5.1 Emission control system
Emission source
Exhaust gas contains carbon monoxide, nitrogen oxides (NOX), and hydrocarbons. It is very important to
control the emissions of NOX and hydrocarbons as they are a major contributor to air pollution. Carbon
monoxide is a poisonous gas. The emission of fuel vapors is a source of pollution as well. The
POWERHOUSE® generator engine utilizes a precise air-fuel ratio and emission control system to reduce
the emissions of carbon monoxide, NOX, hydrocarbons, and evaporative fuel emissions.
Regulation
Your engine has been designed to meet current Environmental Protection Agency (EPA) and the California
Air Resources Board (CARB) clean air standards. The regulations dictate that the manufacturer provides
operation and maintenance standards regarding the emission control system. Tune up specifications are
provided in the Specifications section and a description of the emission control system may be found in the
appendix to this manual, Adherence to the following instructions will ensure your engine meets the emission
control standards.
Modification
Modification of the emission control system may lead to increased emissions. Modification is defined as the
following:

Disassembling or modifying the function or parts of the intake, fuel, or exhaust system.

Modifying or destroying the speed governing function of the generator.
Engine faults that may affect emission
Any of the following faults must be repaired immediately. Consult with your authorized POWERHOUSE®
service center for diagnosis and repair:

Hard starting or shut down after starting

Unstable idle speed

Shut down or backfire after applying an electrical load

Backfire

Black smoke and/or excessive fuel consumption
22
500Wi OM
Replacement parts and accessories
The parts making up the emission control system applied to POWERHOUSE® engine have been
specifically approved and certified by the regulatory agencies. You can trust the replacement parts supplied
by POWERHOUSE® have been manufactured to the same production standard as the original parts. The
use of replacement parts or accessories which are not designed by POWERHOUSE® may affect the engine
emission performance. The manufacturers of replacement parts and accessories have the responsibility to
guarantee that their replacement products will not adversely affect emission performance.
Maintenance
Maintain the generator according to the maintenance schedule in this section. Service items more frequently
when used in dusty areas, or under conditions of high load, temperature, and humidity.
Air Quality Index (only for California certified models)
CARB requires that an air quality index label be attached to every certified engine showing the engine
emission information for the emission duration period. The label is provided for the user to compare the
emission performance of different engines. The lower the air index, the better the engine emission
performance. The description of durability is helpful for the user to learn the engine emission duration period
and the service life of emission control system. Refer to the warranty section of this owner’s manual for more
information.
The air quality index label is designed to be permanently affixed to the generator and removal should not be
attempted.

5. Visually inspect the spark plug. Discard it if the insulator is cracked or chipped.
Clean the spark plug with a wire brush if it is to be reused.
6. Measure the plug gap with a feeler gauge.
7. The gap should be 0.024-0.028in (0.6-0.7mm). Correct as necessary by carefully bending the side
electrode.
8. Install the spark plug carefully, by hand, to avoid cross-threading.
9. After a new spark plug has been seated by hand, it should be tightened 1/2 turn with a wrench to
compress its washer. If a used plug is being reinstalled, it should only require 1/8 to 1/4 turn after
being seated.
10. Reinstall the spark plug cap on the spark plug securely.
11. Reinstall the spark plug access door.
■ The spark plug must be securely tightened. An improperly tightened plug can
become very hot and possibly damage the generator.
■ Never use a spark plug with an improper heat range.
■ Always use an A7RTC resistor-type spark plug. Using a non-resistor spark
plug will interfere with AC output.

6. TRANSPORTING and STORAGE
6.1 Transporting the generator
To prevent fuel spillage when transporting or during temporary storage, the generator should be secured
upright in its normal operating position with the fuel valve and engine switch in the ―OFF‖ position.
When transporting the generator:
■ Do not overfill the gas tank.
■ Do not operate the generator while it is on or in a vehicle.
■ If you must transport the generator in an enclosed vehicle, drain all fuel
from the generator.
6.2 Short term storage of the generator
During short term storage, the generator should be secured upright in its normal operating position with the
fuel valve and engine switch turned ―OFF‖.
Avoid placing the generator in direct sunlight when storing
If the generator is left in an enclosed area or vehicle, high temperatures inside could cause residual fuel to
vaporize resulting in possible explosion.
30
500Wi OM
6.3 Storing the generator for an extended period:


Gasoline is extremely flammable and explosive under certain conditions.
Do not smoke or allow flames or sparks in the area.
1. Be sure the storage area is free of excessive humidity and dust.
2. Regardless of whether you plan to store your generator with or without fuel, add an appropriate
amount (per the instructions on the bottle) of fuel stabilizer and run the generator for 5 minutes.
This will assure that any fuel trapped in the system will have the stabilizer in it. If you do not drain
the fuel, it is best to keep the tank full, as it will be less likely to form condensation in the fuel tank.
You may also choose to add the fuel stabilizer and run the unit until it is out of fuel. If you choose
to drain the fuel, then continue on with the instructions below.
3. To drain the gasoline from the fuel tank, turn the engine switch to the OFF position.
4. Attach a hose to the drain fitting on the carburetor and place the other end of the hose into an
approved gasoline container.
5. Turn the fuel valve ON, and loosen the carburetor drain screw and drain the gasoline into the
approved gasoline container.
6. After the fuel tank has been drained, with the drain screw loosened, disconnect the spark plug
wire and pull the starter grip 3 to 4 times to drain the gasoline from the fuel pump.
7. Turn the fuel valve to the OFF position, and tighten the drain screw securely.
8. Change the engine oil.
9. Remove the spark plug and pour about a tablespoon of clean engine oil into the cylinder.
10. Crank the engine several revolutions to distribute the oil and then reinstall the spark plug.
11. Slowly pull the starter grip until resistance is felt. At this point, the piston is coming up on its
compression stroke and both the intake and exhaust valves are closed. Storing the engine in this
position will help to protect it from internal corrosion.
6.4 Exercising the Generator
It is essential that the generator be exercised on a regular basis. This will prevent the accumulation of
varnish or sludge in the fuel system and remove moisture from the generator windings. Additionally the
engine seals and moving components will be lubricated. Exercise the generator by running it with at least a
1/2 load (225W) for 15 minutes per month. Gasoline fuel treatments to prevent contamination of your fuel
supply are available from your dealer. Fuel varnishing necessitating replacement of the carburetor is not a
warrantable failure.
