You must make sure your generator cansupply enough
rated (running) and surge (starting) watts for the itemsyou
will power at the sametime. Follow these simple steps:
I. Select the itemsyou wilt power at the same time.
2. Total the rated (running) watts of these items.Thisis
the amount of power your generator must produce to
keep your itemsrunning. SeeFigure 9.
3. Estimate how many surge (starting) watts you wilt
need.Surge wattage isthe short burst of power
needed to 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 addingonly the
item(s)with the highest additional surge watts to the
total rated watts from step 2.

Power Management
To prolong the lifeof your generator and attached devices,
it is important to take care when addingelectrical loadsto
your generator.There should be nothing connected to the
generator outlets before starting its engine.The correct
and safeway to managegenerator power is to sequentially
add loadsasfollows:
I. With nothingconnected to the generator, start the
engine asdescribed in this manual.
2. Plugin and turn on the first load,preferably the largest
loadyou 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 loadsthan the generator capacity.Take
specialcare to consider surge loads in generator capacity,
asdescribed above.
