Make sure the generator can supply enough continuous (running)
and surge (starting) watts for the items you will power at the
same time. Follow these simple steps.
1. Select the items you will power at the same time.
2. Total the continuous (running) watts of these items. This is
the amount of power the generator must produce to keep
the items running. See the wattage reference chart at
right.
3. Estimate how many surge (starting) watts you will need.
Surge wattage is the short burst of power needed to start
electric motor-driven tools or appliances such as a circular
saw or refrigerator. Because not all motors start at the
same time, total surge watts can be estimated by adding
only the item(s) with the highest additional surge watts to
the total rated watts from step 2.

To prolong the life of the generator and attached devices, it
is important to take care when adding electrical loads to the
generator. There should be nothing connected to the generator
outlets before starting its engine. The correct and safe way to
manage generator power is to sequentially add loads as follows:
1. With nothing connected to the generator, start the engine
as described later in this manual.
2. Plug in and turn on the first load, preferably the largest
load you have.
3. Permit the generator output to stabilise (engine runs
smoothly and attached device operates properly).
4. Plug in and turn on the next load.
5. Again, permit the generator to stabilise.
6. Repeat steps 4 and 5 for each additional load.
Never add more loads than the generator capacity. Take
special care to consider surge loads in generator capacity as
previously described.
Do not overload the generator’s capacity. Exceeding the
generator’s wattage/amperage capacity can damage the
generator and/or electrical devices connected to it.
