ELECTRICAL
GENERATOR CAPACITY
Make sure the generator can supply enough continuous (run-
ning) 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.
Example:
Tool or Appliance
Continuous
(Running) Watts
Surge
(Starting) Watts
CD Player 100 0
Airless Sprayer 600 1200
Electric Drill 600 900
27 in. Television
500 0
Light (75 Watts)
75 75
1875 Total
Running Watts
1200 Highest
Surge Watts
Total Continuous (Running) Watts 1875
Plus Highest Additional Surge Watts + 1200
Equals Total Generator Output Required 3075
POWER MANAGEMENT
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 stabilize (engine runs
smoothly and attached device operates properly).
4. Plug in and turn on the next load.
5. Again, permit the generator to stabilize.
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.

CAUTION:
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.
