Do Not Overload Generator

Overloading a generator in excess of its rated 
wattage capacity can result in damage to the 
generator and to connected electrical devices.

To prolong the life of your generator and 
attached devices, follow these steps to add 
electrical load:

1. Start the generator with no electrical load 
    attached.
2. Allow the engine to run for several minutes 
    to stabilize.
3. Plug in and turn on the first item. It is best to 
    attach the item with the largest load first.
4. Allow the engine to stabilize.
5. Plug in and turn on the next item.
6. Allow the engine to stabilize.
7. Repeat steps 5-6 for each additional item.
