Portable Generator FAQ

What is the difference between rated watts and maximum (surge) watts?
Rated watts describe the amount of power the portable generator can produce continuously. Maximum wattage is the power that the generator can produce for short periods of time. Motor starting is a good example of maximum wattage requirements.

What type of oil is recommended? How often should it be changed?
Above 40°F, use SAE 30. Below 40°F and down to 10°F, use 10W-30. Below 10°F, use synthetic 5W-30. Oil should be changed after the first 8 hours of operation and every 200 hours of run time thereafter.

When should I add engine oil through the spark plug hole in my generator?
Adding a little bit of oil through the spark plug hole in your generator so that it will directly enter the cylinder will prevent it from rusting. This should be done if you don’t plan to use your generator for a long time.

What type of gasoline is recommended?
Use clean, fresh unleaded gasoline with a minimum 85 octane rating. Turn off the generator engine and allow it to cool about 2 minutes before refueling. Never put gas into your generator while the engine is running.

Why should I use a gas stabilizer or additive for my generator?
The use of a gas stabilizer or additive will minimize the formation of fuel gum deposits during storage. Additives and stabilizers may be added to the gasoline in the fuel tank of the engine, or to the gasoline in a storage container. Make sure your fuel supply is reliable over time with the appropriate additives or stabilizers.

Does a portable generator require installation?
No. A portable can power individual appliances using extension cords. Using a manual transfer switch is even a safer way to power items in the house because it will block any power from back feeding in the power lines. It will also avoid a bunch of extension cords and allow you to power items hardwired into your house like a furnace fan.

Should the fuel be drained when storing the portable generator?

Yes. It is highly recommended that you drain the fuel from the tank and run the carburetor dry. You should never store combustible materials in your home or vehicle. Remember: You should never operate a generator in a confined space, particularly inside your home or garage. Carbon monoxide is deadly and can kill you without you ever noticing it.

Can I vent the exhaust out of an enclosed area?
No. Never run the generator in your home or an enclosed area adjacent to living spaces. Portable generators are designed to run outside where there is plenty of ventilation.

Can the generator be used during inclement weather?
Generators can be used during a wide variety of weather conditions but provide as much rain protection as you can. Protect your portable generator from the elements when not in use to prevent shorting and rusting. NEVER run a generator indoors.
