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. Foiiow these simpie steps:
1. Select the items you wiii power at the same time.
2. Totai the rated (running) watts of these items. This is
the amount of power your generator must produce to
keep your items running.
3. Estimate how many surge (starting) watts you wiii need.
Surge wattage is the short burst of power needed to
start eiectric motor=driventools or appiiances such as a
circular saw or refrigerator. Because not aii motors start
at the same time, totai 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.

watts cannot exceed 5300.
Power
Management
To proiong the iife of your generator and attached devices, it
is important to take care when adding electrical ioads to your
generator. There should be nothing connected to the
generator outiets 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. Hug in and turn on the first ioad, preferably the largest
load you have.
3. Permit the generator output to stabiiize (engine runs
smoothly and attached device operates properly).
4. Hug in and turn on the next ioad.
5. Again, permit the generator to stabiiize.
6. Repeatsteps 4 and 5 for each additional load.
NEVERadd more loads than the generator capacity. Take
speciai care to consider surge loads in generator capacity, as
described above.
