DON'T OVERLOAD GENERATOR
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:
1. Select the items you will power at the same time.
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 the table
on the 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.

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:
1. 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.
