Capacity
You must make sure your generator can supply enough
rated (running) and surge (starting) watts for the items you
will power at the same time. Follow these simple steps:
I. Select the items you will power at the same Ume.
2. Total the rated (running) watts of these items.This is
the amount of power your generator must produce to
keep your items running. See Figure 9.
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
appliancessuch 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.

Power Management
To prolong the life of your generator and attached devices,
it is important to take care when adding electrical loads to
your generator.There should be nothing connected to the
generator outlets before starting it's engine.The correct
and safe way to manage generator power is to sequentially
add loads as follows:
I. With nothing connected to the generator, start the
engine as described 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 described above.
