DOH'TOVERLOADGENERATOR
Capacity
You must make sure your generator can supply enough rated
(running) and surge (starting) watts for the itemsyou will
power at the sametime. Followthese simple steps:
1. Selectthe 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 manysurge (starting) watts you will need.
Surge wattage is the short burst of power neededto
start electric motor-driven tools or appliancessuch as a
circular saw or refrigerator. Becausenot all motors start
at the sametime, 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 exceed5600. Also,
given the 5600 watt rated limit, additional surge (starting)
watts cannot exceed 8600.
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, preferablythe largest
load you have.
3. Permit the generator output to stabilize (engine runs
smoothly and attached deviceoperates properly).
4. Plug in and turn on the next load.
5. Again, permit the generator to stabilize.
6. Repeatsteps 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
describedabove.
