DOH'TOVERLOAD GENERATOR
Capacity
You must make sure your generator can supply enough rated
(running) and surge (starting) watts for the itemsyou will
power at the same time. Follow these simple steps:
1.
Select the itemsyou will power at the same time.
2.
Total the rated (running) watts of these items. This isthe
amount of power your generator must produce to keep
your items running.
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. Becausenot 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.

NOTE:The rated (running) watts cannot exceed 6300. Also,

watts cannot exceed 9100.
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 managegenerator 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.
NEVERadd more loads than the generator capacity. Take
special care to consider surge loads in generator capacity, as
described above.
