natural_image
Close-up of a mechanical clamp or bracket with a metal rod inserted, set against a grassy background (no text or symbols visible)Grounding codes can vary by location. Please contact a local electrician to check the grounding regulations for your area.

WARNING: Failure to properly ground the generator can result in electrocution.
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 a dealer perform this carburetor modification. This engine, when operated at high altitude with the carburetor modifications for high altitude use, will meet each emission standard throughout its useful life. Even with carburetor modification, engine horsepower will decrease about 3.5% for each 1,000-foot (300-meter) increase in altitude. The effect of altitude on horsepower will be greater than this if no carburetor modification is made.
When the carburetor has been modified for high altitude operation, the air/fuel mixture will be too lean for low altitude use. Operation at altitudes below 5,000 feet (1,500 meters) with a modified carburetor may cause the engine to overheat and result in serious engine damage.

natural_image
Close-up of a hand holding a white plastic cup, with a control panel visible in the background (no text or symbols on the cup or background)1. Check the oil
The generator is equipped with an automatic shutoff to protect it from damage due to low oil. Nonetheless, you should check the oil level of the engine before each use to ensure that the engine crankcase has a sufficient amount.
To check the oil level:
a. Make sure the generator is on a level surface.
b. Remove dipstick.
c. With a dry cloth, wipe the oil off of the stick.
d. Insert the dipstick completely back into its hole in the engine case. the pull it out again. There should now be oil on the stick. If there is no oil on the stick, or oil only at the very end of the stick, you should add oil until the engine crankcase is filled (see "Adding Oil" portion of the "Maintenance" section).
e. Be sure to replace the dipstick when finished checking oil.
NOTE: The oil capacity for this generator is 54 fl. oz (1.6L).
Step 2 - Check the Gas Level

natural_image
Close-up of a car door with a switch and circular icon (no visible text or symbols)1. Check Fuel Level

IMPORTANT: At this point you should be familiar with the procedures described in the first portion of this section entitled "GENERATOR SETUP" If you have not yet read this section, go back and read it now.
USING THE GENERATOR
AC Usage
- You may connect electrical devices running on AC current according to their wattage requirements.
- The chart below shows the rated and surge wattage of your generator according to its model number.
- The rated wattage corresponds to the maximum wattage the generator can output on a continuous basis.
- The surge wattage corresponds to the maximum amount of power the generator can output for a short period of time. Many electrical devices such as refrigerators require short bursts of extra power, in addition the rated wattage listed by the device, to stop and start their motors. The surge wattage ability of the generator covers this extra power requirement.
| Fuel Source Rated (Running Wattage) Surge (Peak) Wattage | |
| Gasoline 12,000 15,000 | |
| Propane 11,400 14,250 | |
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 wish 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 you cannot find this wattage, you may calculate it by multiplying the Voltage requirement by the Amperage drawn: Watts = Volts x Amps. If these specifications are not available you may estimate the Watts required by your device by using the chart on the next page.
Once you have found the rated wattage requirement of each electrical device, add these numbers to find the total rated wattage you wish to draw from the generator. If this number exceeds the rated wattage of the generator, DO NOT connect all these devices. Select a combination of electrical devices, which has a total rated wattage lower than or equal to the rated wattage of the generator.

Proper maintenance and storage of your generator is essential to ensure trouble free use of your generator when you need it.
By following the maintenance and care requirements, you can keep your generator running smooth and efficient for years to come.
MAINTENANCE AND CARE
Proper routine maintenance of your generator is essential for safe, economical, and trouble-free operation. It will also help reduce air pollution.

WARNING: Improper maintenance, or failure to correct a problem before operation, can cause a malfunction in which you can be seriously injured or killed. Always follow the inspection and maintenance recommendations and schedules in this instruction manual.
• Make sure the engine is off before you begin any maintenance or repairs.
- Let the engine and exhaust system cool before touching.
- To reduce the possibility of fire or explosion, be careful when working around gasoline. Use only a nonflammable solvent, not gasoline, to clean parts. Keep cigarettes, sparks, and flames away from all fuel related parts.
Maintenance Schedule
Remember that this schedule is based on the assumption that your machine will be used for its designed purpose. Sustained high-load, high temperature operation, or use in unusually wet or dusty conditions, will require more frequent service.

natural_image
Close-up of a hand pouring liquid into a cup, with industrial control panel visible (no readable text or symbols)1. Check the oil
The generator is equipped with an automatic shutoff to protect it from damage due to low oil. Nonetheless, you should check the oil level of the engine before each use to ensure that the engine crankcase has a sufficient amount.
To check the oil level:
a. Make sure the generator is on a level surface.
b. Remove dipstick.
c. With a dry cloth, wipe the oil off of the stick.
d. Insert the dipstick completely back into its hole in the engine case. the pull it out again. There should now be oil on the stick. If there is no oil on the stick, or oil only at the very end of the stick, you should add oil until the engine crankcase is filled (see "Adding Oil" portion of the "Maintenance" section).
e. Be sure to replace the dipstick when finished checking oil.
NOTE: The oil capacity for this generator is 54 fl. oz (1.6L).
Changing the Oil
Worn out or dirty oil does not cool the generator properly and can lead to catastrophic engine damage.
In addition to regular oil changes, it is necessary to drain the oil from the crankcase if it has become contaminated with water or dirt.
